quiet 70mm fan

[tp4tissue]

Is there such a thing?

Low RPM ones.  What are you trying to cool specificaly?

Low RPM ones.  What are you trying to cool specificaly?

vrm section of the graphics card.. nothing else will come close to fitting there.

I mounted a 120mm cpu cooler to this card. but the 70mm fans I have, double ball bearing ones are a bit rattle-ee.

[tipo33]

shop around for some 70mm fans.  you may be able to use sleve bearing fans depending on the orientation of the card.  Depending on the temps you may want to get a lower RPM fan.  Really depends.  What card is it?

I don't know if any 70mm fit your definition of quiet but there are numerous techniques to make them quieter.
From brushless motor with ball bearings to careful turbulence management. It really depends how much air you want and the clearance you have to bring it there.

Here's a good reading for you

QOTD - The loudest fan of all is pretty quiet compared to a Harley Davidson.

You can try one from Noctua:

Or a Gelid Silent 7.  I'm sure there are others too, but I've never looked into 70mm fans.

[BucklingSpring]

Stupid question but are you sure you are looking for a 70mm? It doesn't seem to be a standard size (at least according to Noctua)
40, 60, 80, 92, 120, 140.... No 70.

70mm fans do exist but they are not common.  If I'm not mistaken they were used on stock AMD coolers for a while.

I don't have any personal experience with this fan but you could try the Gelid Silent 7.

If it was too noisy you could use a Zalman RC56 connector to reduce the fan speed.

Best bet for cooling VRM is probably water.

Best bet for cooling VRM is probably water.

This, or if you can, lower the voltages. If you need high voltage to maintain good OC, water cooling is the biz. Of course, the cost is pretty high. Just a decent block for a single card can be $100 and they won't work on the next card you buy (this is why I am still running a pair of GTX460s!).

Are there already decent heatsinks on the VRM chips? If you can dedicate a full air channel through the case which runs over the VRM chips or reorganise the overall airflow (so they get cold air from outside the case directly) it can also be more benificial then simply adding a fan. If they don't have a heatsink, then add one first. On some boards, they haven't all been soldered on flush, so they may not be angled flat or the same height which makes it difficult to fit a heatsink, though. In this case you can try small individual heatsinks per chip.

The Gelid will be quiet (relatively speaking), but it doesn't have the highest flow rate (about half of what the highest flow is for 70mm fans). It'll do the job if the flow path is good (getting cold air from outside the case).

For qualification reference, I have been OC'ing PC's since 486DX days and have achieved the highest score on 3DMark for my combination of hardware a while back (with a daily use setup): http://www.3dmark.com/3dm11/2773922

I see it's still the highest for a Phenom X2 and GTX460 combo  I have since upgraded to an X6, but it doesn't OC as well as my X2.

Water is impossible..

I'm doing a Quiet PC.. 

I've not heard a single water pump that doesn't make a relatively high pitched  rrrrrzzzzz.......  sound.

My pump is mounted on silicon dampers and is vewy, vewy quiet. In general water cooling is a LOT quieter than air, just got to find the right parts. The noisiest part of my currect system is a one of the radiator fans... gonna replace them all with a bigger, slower one soon. Here is a pic:



The fans pull the air through the rad into the case, then it goes out the top, back and front. Got 2 loops, one for the CPU, 1 for the GPUs, the radiator also acts as a reservoir.

There are a lot of different types of pump to choose from, some are even submersed (my previous system had one of these, it was designed for a fountain).

I have personal experience with the Gelid Silent 4 and Silent 6, they're pretty quiet, I might try to get a video later of it OuO

I second that...
Switched to low RPM Noctuas some time ago (CPU and case), good stuff!

I honestly don't think the noctua price is justified..  especially when we're talking low rpm.. 

now, if you're running high rpm fans, then noise become an "issue"..


Then some people turn this towards the "middle" of the road argument, high-er performance @ only slightly increased noise...  this part is so difficult to determine because of disagreement on noise-profile, the frequency vs perceived loudness.


I had the nhd14 on an older setup.. I really think noctua is a triumph in advertising rather than real technological improvement..
