From what I've read and talked to friends about it Liquid is better than air cooling, but for me... A regular ass gamer it's way too much hassle when air fans do the job pretty well. Hell these days you don't even have to worry about after market CPU fans when overclocking.

I'd love a silent liquid system, but it's alot of work.

Also really expensive.

290 for the kit + 100 for the gpu waterblock

Air cooling failure: PC shuts down because of overheat protection...
Water cooling failure: If it's the pump, same as above, but if it's the tubing, anything from defect components (friend fried 2000 Euros worth of GPUs) to burning ya house down :/

That's expensive indeed. By reading this thread I'd say the extra work + price + dangers do not compensate. I mean, air cooling is 'equivalent' right?

Liquid cooling is quieter than air too. If you aren't gonna do any heavy overclocking though, liquid cooling isn't necessary and you could just get one of the closed loop solutions.

I love to watercool.  That being said the maintanence kills me,  draining the water out, replacing leeched hosing.  Sometimes it is necesary though,  especialy in the climate here.

Liquid cooling does look really... cool  :cool:, but air cooling is so good anymore that unless you're doing some serious overclocking, it's not really necessary.  One of the systems at my work got a leak, and the user didn't notice since it was under his desk, ended up trashing the whole system, and was a PITA to clean up.  Kind of turned me off from liquid cooling.

Someone else already said this but for me it was also noise. Prior to my current pc I used all air cooling and the noice from the fans and vibration was annoying. When you playing online and using a microphone and your teammates can't hear your voice over the fans .....

I have done both, and as awesome as a full custom loop is, I just don't like the amount of added time to pull a simple part.  I am a tinkerer, and didn't like draining the loop in order to move parts, then reassembling and priming everything again.  Also, I think some of the air coolers out there look very good.  The quietness of the machine with the full loop was great, but having gone back to a tower cooler, I invested in some good quiet fans and haven't regretted it at all.  My rig sits on my desk behind my monitor, and when in normal use is nearly in-audible.  I use a fan controller to up the rpm when I game, even though I probably don't need to, and even then, the only thing I hear is the air whooshing a little and the fan on my reference cooler (i have an aftermarket cooler ready to go on my gpu to make it even quieter  :thumb:)

corsair closed loop H Series.

never worry about leaks,evaporation,algae.

almost as powerful as triple rad setups (the 2x120), none of the hassle.

there are now many closed looped systems available from different manufacturers (i only say corsair cuz that's my experience)

i think last i saw Artic cooling is even releasing a  gpu only closed loop 120mm

that means on most modern cases you could have a
2x120mm cpu closed loop connect to the top

and a 1x120mm gpu connect to the back.

you don't have to deal with leaks, reservoirs, cleaning...

admittedly it is a 2 loop system, it's not gonna be as powerful as a more finely tuned triple rad, and have 2 pumps, but i'm sure it'll be at least 75% cheaper, be nearly as quiet and nearly as effective.

i don't remember the last time i opened up my pc or even checked my overclock, but it's an amd be dual core something that i unlocked the other 2 cores (so it's a quad) and went from 2.5 to 3.5G overclock. I think i've been running it for 2 years? this is on quiet too, i have the pump on the quiet setting (1 of 3) and my fans are controlled by speedfan, they've been spinning at 45% for years (unless i reboot, they go 100%).

the last air cooler i bought was some $50 monstrosity that worked really well but weighed as much as a show dog and needed 2 120mm fans. I gladly payed $90 for this closed loop 2x120mm corsair (i think it was a sale)

If you design your loop right, and in the right case maintenance and removal is a cinch. To drain it, I just open the plug in the bottom of the res, and let it come out. To fill it I turn it on it's side and fill through the drain port. That's something I need to address though since is a small inconvenience of bleeding it this way, as a bubble can seize the pump easily since it has to work and doesn't have gravity helping feed the water in but it's not too bad. One of these days I will find a matching Y fitting so I can fill through the top of my res, as the in from the rad goes in there and it's the only opening on the top. If I need to remove anything not part of the loop I can just do so without have to drain. I only need to unfasten the CPU block and push it out of the way. After that I can pull the cpu or motherboard if I want to. When I am done I only have to retim and fasten the block back.
Though, I don't put GPU under water anymore. The return on selling off blocks for GPU is abysmal. The biggest con is the initial cost of getting everything you need. Luckily I have been able to use the same components for quite some time since we have had intel being kind enough not to change the cooler mounting for CPU on consumer standard motherboards since s775.
For me the biggest pros are the amount of cooling you get with nearly no noise. My typical idle temps are about 3c above ambient room, and the only time I have seen it go 15c above ambient was during extended torture testing. More typical load temps for gaming and such is more like +8c above ambient. That's pretty decent for i5 750 @ 3.6gHz I think. It's really difficult to get as good cooling on air without a considerable increase in the decibels.

My favorite system though for lack of noise is a fanless convection cooled HP t5720 with the pci add on a geforce 6200 and an upgraded 16GB DOM. Being free of any moving parts it's great. I use that for my retro gaming DOS/98 machine.
The way temps keep going down, I hope to be able to have some similar cooling on modern gaming grade components in the near future.

the argument against water cooling is that you may go overboard and it is always expensive except when you go for those closed loop kits.

ouch my wallet still hurts

i guess the same could be said for any high end system but with water cooling you never really see a system using the cheapest parts you can get. (except for the closed loop kits or some ghetto thermaltake kit)

They're nowhere near as good as a 3x120mm rad setup.  The H100 is still worse than a good custom loop with a 240mm rad.  In fact, the H100 is worse than the Thermalright Silver Arrow SB-E Extreme even on the extreme setting and only beats out the NH-D14, Silver Arrow SB-E (not the Extreme version), and TC14PE when you put it on the loud high performance setting.

CLCs are really an aesthetic choice, not a performance choice, and I speak as someone who has one.

The reasons to buy a CLC are the following:

- You like the way they look.

- You have a system you move around a lot.

- Your case won't fit a good tower heatsink, but can fit a 120mm to 240mm radiator.

In general, it's best to either go with high end air cooling for performance, noise, and value, CLCs when you have case restrictions, or a custom loop if you have the money for it.

i haven't checked out any OC sites in 2 years, but i'm pretty sure at the time i got my corsair h100 at idle it beat out any $60+ dual fan air cooler at max. and when i said a 3x rad kit, i meant something like this.
http://www.frozencpu.com/products/14572/ex-wat-187/Swiftech_H20-320_EDGE_HD_Series_Liquid_Cooling_Kit_-_Black_CPU_Block_Universal_Mount.html?gclid=CJiDl-TRxrkCFXDNOgodgGoA7g

a semi custom kit from swiftech, built in res popular pump, swiftech rad and cpu block. it still costs almost 2x more than a CLC at 100bucks or 150ish bucks, and it still needs a degree or maintainance and care that a CLC does not need.

and this is the starting price for what'd consider "custom" it just goes up from here.

On the quieter mid-range setting, the H100 loses out to the NH-D14, Silver Arrow, Silver Arrow SB-E, TC14PE, and, I believe, the Archon SB-E.  It only beats them when you put it in the very loud high performance setting and only then by a 1C, 2C on a good day.  The Silver Arrow SB-E Extreme is as loud as the H100 on the highest setting and beats it at the highest setting by several C.

That kit you're linking to is ancient in water cooling terms.  It loses out to Swiftech's H220 and is handily beat by any custom loop on the market with a 240mm rad.  The XSPC Raystorm with AX360 (http://www.frozencpu.com/products/20836/ex-wat-264/XSPC_Raystorm_750_AX360_Universal_CPU_Water_Cooling_Kit_New_Rev_4_Pump_Included_w_Free_Dead-Water.html?tl=g30c321s1310) is dramatically cheaper than the Swiftech you linked to and will dance circles around it and the H100.  You can also pick up an even cheaper XSPC Raystorm kit with 240mm rad (http://www.frozencpu.com/products/21235/ex-wat-270/XSPC_Raystorm_750_EX240_Extreme_Universal_CPU_Water_Cooling_Kit_New_Rev_4_Pump_Included_w_Free_Dead-Water.html?tl=g30c321s1310) that will dance circles around the H100, H100i, and any other 240mm CLC and costs the same as the CLCs and a new pair of fans.

I had that basic XSPC kit except with an EK supreme cpu block (before the raystorm was introduced).  Great kit for the money, and you can upgrade it in pieces if you want.  Pump/res was plenty powerful enough to add another 120 rad and gpu block in the loop.  If you buy used, you could probably do the whole loop for under $100 (I did  :thumb:)

Yeah, if you know what to look for and keep an eye out for used parts, you can easily build a custom loop for around $100-150.  You can pick up a DDC pump here for $35 (http://bmaverickddcpumps.wordpress.com/buy-ddc-pumps-here/) and can sometimes find one cheaper, you can usually find a 240mm rad anywhere from $25-35, you can find a waterblock from anywhere from $35-50, you can go resless and just use a t-line or can get a res for $20 or so, and then it's just your fittings and some cheap tubing and distilled water.

the first time you setup liquid cooling it sucks. it is scary, expensive, and no set of instructions are sufficient.

the second time you setup liquid cooling it is cake. so easy.

i would never build a desktop without liquid cooling at this point in my life. partly because i dont have A/C in my house (which is in denver) and mostly because Intel cpus run hot as **** these days.

but here is some advice from a liquid cooler:

GPU liquid cooling is awesome.  If you want to do this go EVGA and buy the EVGA waterblock for your card (~150$)

RAM liquid cooling is full retard status. dont do it.

you cannot really **** up a closed loop system.

most electronics are fine if they get wet. just dont send any power through them until they are fully dried off. wait 48 hours for full dryness.

your case is very important if you want to water cool. dont just buy any case.

thats it.

Post by: eth0s on Thu, 12 September 2013, 19:38:36
I have been building water cooled rigs for 10 years.  It's expensive and time consuming.  It's also overkill for anything but the most extreme systems.  And once you have more than 10 fans in your case, it's no quieter than an air-cooled rig. 

As for danger with water cooling, it's there.  Anybody with long-term water cooling experience, who is not a liar, can list the parts that have been ruined by leaks.  In my case it's been two mobo's, and two separate graphics cards.  All expensive at the time.  Not to mention the hassle of replacing them.  Also only one time was it an obvious leak, with water visibly splashing around (which happened in my early noobish water cooling days), and said water caused a snap, sizzle, and a pop, with a little puff of grey smoke coming from the graphics card.  The other times it was the tiniest little blurble of a leak coming from a defective fitting, that I had to track down by adding UV reactive dye to the loop and find the leaky fitting with UV light.  After two mobo's were killed, I finally learned not to trust anything but straight barbs with hose clamps, which is what we used to use back in the very beginning of water cooling.  I've also had two pumps fail, and a water block warp a graphics card, and ruin it in about 8 months (but that was back when gfx water blocks first came out, and they are all much better now, so that probably won't happen nowadays, but you never know.)  I also had a serious algae bloom happen twice (despite the use of biocides), and I had a bizarre chemical reaction happen from too much biocide which caused the water in my loop to turn into a conductive copper sulfate solution.  I also experienced extreme galvanic corrosion from mixing aluminum and copper.  I know you're not supposed to mix aluminum and copper, but I thought I could fight galvanic corrosion with automotive antifreeze containing pentosin, but I was wrong.  So wrong.  The aluminum gets removed from the aluminum parts and gets deposited on the copper parts.  That's also called electro-plating.  But when it happens without the application of an electric current it's just galvanic corrosion, and the electrical charge is supplied by the ions in the water.  I also experienced extremely low flow from not enough pump head pressure, and cavitation from too much head pressure.

With that said, I still love the challenge and fun of building a water cooled rig.  For the expense and the time however, I am growing a bit weary.  Like any hobby basically, it's really for enthusiasts, and enthusiastic enthusiasts at that.  It's not the most practical way to cool a computer.  I don't want to discourage anybody who wants to get into water cooling, as it really is a great hobby.  However, it can be even more expensive than keyboards.

In fact, right now, I am contemplating my next build as a simple, low-heat, low-noise, air-cooled rig.  I am seriously considering a Haswell i7-4770s paired with a single GTX 770, in a Nanoxia DS1 case.  Low heat, low noise, low hassle, and relatively low price.  For data storage, I am thinking of using 2x Samsung 840 Pro 256GB SSD's (one for the OS, and one for redundant back-up, with all other storage on the cloud.)  I would splurge on 32GB of RAM, probably 2133mhz or higher.  For a mobo, I was thinking Gigabyte or Asrock, but nothing costing more than ~ $180.  Anyway the whole rig should come in under $1,500, and it should be able to handle any game or task I throw at it.  And I don't need to worry about my OC (because you can't OC the i7-4770s), and I don't need to worry about maintaining the loop or checking for leaks, or a warped gfx, or algae, or galvanic corrosion, etc.  And if I want to add a second GTX770, I can just plug it in, and start gaming.

@ eth0s ... I will agree with most of what you said and don't want to start an in-depth discussion of WC rigs, but I will say that the 17 Gentle Typhoon 1850's on my Aquaero is NO WHERE near as loud as what it took to air cool three GTX 470s. I would guess my average RPM for the fans is 800 to 900 and the rig is very close to dead silent. The Aquaero is an absolutely amazing controller. I only ramp up the rpms when needed, based on component temp, water temp or temp deltas, which are all setup in the controller.

Also, like yourself, I really enjoy building things. It was a great learning experience but next time I will go air, if I ever even build another pc. I don't game anymore and portables, including smartphones can do most things nowdays.

Also, like yourself, I really enjoy building things. It was a great learning experience but next time I will go air, if I ever even build another pc. I don't game anymore and portables, including smartphones can do most things nowdays.

Yeah, in previous builds, I went from GT AP-15's, to AP-14's, to AP-13's, and finally down to AP-11's (500 rpm - a truly silent fan). 

Right now, I've got the Aquaero too, but it doesn't do PWM all that well.  You need to daisy-chain your PWM fans, or use an interlink like a sunbeam rheobus, which is what I'm doing.  In this current WC build, I used 7x 140mm PWM controlled fans.  I thought it would be the best cooling vs. noise.  It's pretty good, with the 140mm fans going from 600 to 900 rpms.  But 140mm fans are still not as good at blowing air as GT 120mm fans, and PWM control is not the forte of the Aquaero.  So I had to add a Sunbeam Rheobus PWM controller as well. 

Well, like I said, I'm leaning toward a quick and cheap air cooled build next.  Maybe I can even do it for ~ $1K.  A $1K build seems like an exciting idea to me right now.  I guess I have gone full circle.

If I had a problem with noise, I'd just add some longer cables and stick it in another room :P
Obviously you have not experienced loud. I mean loud enough to wake up every person in a 6 unit apartment building. You literally could not sit at the pc and do anything.

^ + 1.  Yeah.  You have no idea about loud. 

If you want to learn about loud, put one of these Delta's in your case:  http://www.frozencpu.com/products/8147/fan-500/Delta_Mega_Fast_120mm_x_38mm_Fan_-_252_CFM_-_Bare_Lead_PFB1212UHE-F00.html?tl=g36c15s562&id=otNeECuk

You won't need two.

LOL, that is exactly the fan I had, in addition to the 3 on card fans of the 470. It sounded like a freakin jet airplane and the middle card still ran hot. In less than a week I was planning the move to wc.

I'm going to look at one of those giant heatsinks that are passively cooled for a fanless  computer. Although my rooms going to heat up >.>.

But I never overclock since I don't open 74 porn tabs at once like the rest of ya

I overclocked my i5 2500k to 4.6 GHz and can passively cool it with a Hyper 212+.  The only fans I need running in my computer are the built-in PSU and GPU ones.  Idle, the CPU temperature is about 38C, and playing games it's around 83C.

Liquid cooling is quieter, cooler and looks amazing compared to air cooling!

Yes it comes at a price but if you have th money is worth it!

Personally if you design it properly, put it together properly, you wont have any leeks or issues!

My 2500k@stock clock idles around 30c with a Hyper 212+ (fan running) and 4 case fans, am I doing something wrong?

Then again it never goes past ~60C under load...

My favorite post on any forum goes something like this:

"I cool my Intel Xeon Eight-Core Processor with the beanie cap shown here:

I have my cpu OC'd to 5.2 ghz @ 1.118V.  I use my own recipe of toothpaste and bird cr@p for TIM.  I keep my computer in the sauna, and my ambient temps are 49C night and day, but my idle temps hover around 10C, and my max temps get just over 22C. 

I have no fans in my case, but my dog wags his tail near it at least once a day.  My case was carved out of a solid block of acrylic plastic and conducts no heat whatsoever.  The foregoing proves that I am a genius, and cool guy."

I have a H110 (dual 140mm) closed loop system on mine, and I'm pretty happy with it for what I use my computer for. I have the PWM Noctua fans turned all the way down, and it keeps things cool enough for me.

after reading eth0s' words, I dunno if I will try real water cooling now...I was under the assumption that water cooling had come a long way since the early days and that maintenance was very minimal and that risks were also minimal...seems not to be the case at all

As for danger with water cooling, it's there.  Anybody with long-term water cooling experience, who is not a liar, can list the parts that have been ruined by leaks. 

hi long time water cooler and not a liar. i have never ruined any hardware water cooling my systems. i am a hardware technician, and i am patient. maybe that helps.

anywho if you do it right you dont have to worry. when you start taking shortcuts and dont do your due diligence then you will have problems.

or you can go closed loop and never worry and have great water cooling. it isnt as flashy but it works like a champ on a cpu. 


dont be scared. be excited.

I USED TO HAVE A DELL PENTIUM 4 LAPTOP WHERE I'D PUT IT IN THE FREEZER TO KEEP IT FROM OVERHEATING.

I bet it was a Prescott core.   lol

THOSE THINGS MAKE GREAT SPACE HEATERS, DON'T THEY?

Yeah, martin of martinsliquidlabs reviewed it and several other did too.  It's a good unit, though it seems like early models were plagued with some QC issues.

There are risks with CLCs too.  Look at posts where they burst and took out components in systems.  With what you spent on an H110 and four Noctua fans, a custom loop would have been a great alternative without a ton of risk as long as you take your time and double and triple check that you're doing things right. 

Most of the cases where I see something went wrong are user error.  They did something like forgetting to tighten the compression fittings down all the way and to retighten them for the first week or so, forgetting to leak test before turning the computer on, or other things like that.  You're putting water near electronics, so there's always risk, but there's a ton you can do to mitigate that risk.
