A lack of observational skills may cause you issues in other areas of life but when it comes to computers if it works you're doing it right, and if you do it really wrong your nose will alert you to the foul stench of magic smoke being released from whatever you just killed and you'll never make that mistake again.
I wonder how your computer worked with negative pressure though - less air in the case means less air to absorb heat. Unless your case has vents in low down in which case it might have worked nearly as well as with the fan blowing the "right" way...
(always filter the intake)
These days, connectors are keyed and fans have arrows and such.
I had to completely disassemble an old Dolch 486 computer to be able to do repairs to the case... and when I assembled it again, I noticed that I did not know how to reconnect everything properly. "Hmm.. Is this a fan header?"
Of course I did not have any motherboard manual. Soo... It is now sitting unused.

Yeah I know, thought about that after the fact. Just woke up and dropped the ball. I am sure the server can handle it. We live life, make mistakes and hopefully learn from them.
Not all fans have the arrow
Look at the Fins,
The air goes IN the Convex (dome) side, and out through the Concave (swoop) side.

too much science
brain cant handle
my take:
where they stick the sticker (usually), the one with voltage, logo, etc is the out flow

I do use filters but it probably doesn't help that there are two massive fan holes at the top of my case acting as the entrance to a gaping dust circus. I have not done anything about this because I keep telling myself it is a temporary case anyway and that I will get a new one soon, for 2 years.
I've looked at lot of fans, generic Chinese ones, Thermaltakes, Antecs off memory. I have looked for something obvious like arrows, never seen any.
The 140mm fan is probably supposed to create positive pressure within the case. If it is filtered and blowing in the right direction, you will massively cut down on dust regardless of the other fan holes.
My case has big exit holes on top and the rear, but because the intake fans are filtered and the case runs positive pressure, I have never had to dust out the case once, and it's been in use for five years.
I use 3M Filtrete for the intake fans.

It might be common on newer fans, all the fans that I have were purchased no greater than 4 years ago. I just checked my pile of fans and the only ones that don't are the Phobya slim fans. Time for show and tell, not that anyone could be that interested in case fans lol.
The funny thing is that the markings in the corner are just not that noticeable it kinda seems like a waste of time even having it there. I guess you can't accuse a manufacturer of killing your computer from incorrect placement if it is printed on the fan.
whaa....
Are you getting good flow using the filtrete ?
I've noticed that computer fans don't have enough pressure for furnace filter material..
Pressure is very low.

I'm not sure what Filtrete is in the US, the stuff sold in Asia is really thin and designed to be slapped into wall-mounted air conditioners. It doesn't impede airflow much.
I have no idea what a furnace filter is...

Get a really good case. If you have space and don't move often, get a massive full tower and build new parts into it one-by-one.
I started doing this a decade ago and I am certain that every single component in my computer has been replaced at least once, most 2-3 times or more. About every 3 years, when the motherboard is due, I completely dis-assemble it and clean it thoroughly.
With this method, upgrade costs can be contained in the $50-$200 range (per instance) and you can stay up to date painlessly.
I am to the point where I would love to get a new case (mine has half a dozen fans, but all are 80mm, and the USB and audio sockets are on the top rather than the front (it was a "server" model I suppose)) but I am still waiting for just the right one.

Get a case from CaseLabs.. you can pick the parts you want and get just the right one :o
Mine is a "Maxtek" which was made by "Casetek" and is in it that bulletproof/hernia category of cases that just won't give up.
I particularly like the slide-in brackets and mounting hardware throughout, and the nice washable fan filters.
I also have an even heavier and larger case that is likely close to 2 decades old, even more massive and solid, but there are no markings or identifications on it at all. But the Maxtek has the better mix of size and features.
Have you got any photos? it sounds interesting

I just had a look they are some nice cases. I like the simple design. Do you have one? I am just wondering if they are a solid build like they appear in the photos? Or if they are have the standard case feel/build.

Not immediately available. You have to wire these things up in the corner behind the desk and leave them for months at a time, otherwise you injure your back.
And, being ancient, they are strictly beige throughout. I am sure that 99% of modern cases are black, if not worse.
Approximately along the lines of these:

you have to cut some fan slots yourself. if you want silent 120/140mm cooling..
Most of the old stuff weren't designed for high flow.

could you link to the filter ur using?
I've tried from Merv 8 , essentially even that is too restrictive for computer fans..

Sorry, all it shows is the packaging. It's kind of like a fluffy mesh sheet.

I could probably help with that. Built several computers of that era. :thumb:These days, connectors are keyed and fans have arrows and such.

Man that sucks, surely there is some vintage computer forum with someone who could help you out?
