Windows 7: Fan placement in chassis.

Fan placement in chassis.

I'm having real trouble figuring out which way these case fans go. I'm getting confused which side the wind blows as exhaust outside of the case. It would be nice if they came with stickers that said EXHAUST or INTAKE. lol.

This is the fan I purchased is as follows: Amazon.com: Corsair Air Series AF140 LED Quiet Edition High Airflow Fan - Blue (CO-9050017-BLED): Computers & Accessories

I just want to make sure that the fan exhausts through the top of my case. I have a Rosewill Blackhawk.

Additionally, can you guys help me fine a 120mm x 18mm or thinner fan? Thank you.

If you look closely on the sides of the fan body, you should see an arrow faintly molded into the plastic to show air flow direction. Also, air usually flows toward the frame that holds the center hub of the fan blades.

What about 15-18mm fans (120mm) motherboard cooler ones. I am having a hard time finding one. Not sure about how many RPMS I need, too?

Do you care how much noise the fans make?

I'm not sure I ever heard of anyone wanting a fan just to cool the motherboard. Where would you intend to mount it?

Do you have some peculiar situation that you think generates an abnormal amount of heat and therefore requires unusual cooling?

Do you have any specific reason to think that your temps are too high without this motherboard fan?

Downblowing CPU coolers usually provide a greater degree of motherboard cooling than do standard tower coolers, but the more typical idea is to just ensure that your fans generally encourage front to rear airflow--sucking cool air in on the front side and blowing it out the backside. Fans on tower coolers should be mounted in such a way as to coincide with this front to rear idea.

Fans on the top or side panels of the case may or may not help--you'll have to experiment. If you are a practicing fanaholic, you'll want a bunch of case fans regardless. Otherwise you might want 2 or 3.

That case has comes with 4 fans and can mount a total of 6 or 7. I'd start with one or two front intakes and one rear exhaust and then evaluate temps and noise. If temps were too high, I'd experiment with the other fans or consider replacing the two ro three I started with, depending on noise levels.

Here's a list of slim 120 mm fans under $25:

The part with the frame holding the fan is the exhaust side.

You want AF fans to blow free air, you want SP fans for radiators and when the fan is against a hard drive cage.

Although, I use AF`s everywhere accept the radiator.

RPM`s are not a major concern, your not gonna run them at max rpm anyway.

Just browse through Newegg for fans, I doubt you`ll find thin fans, I can`t even add fans to the bottom of my rad because they would hit the motherboard. I would need to find some adapters and use 120 mm fans.

Corsair sells 2 types of fans, Performance edition and Quiet edition, so do your research and get what you want.

Fan rpms can be set in the mother board bios I have mine on turbo mode which is about 1500rpms

cpu liquid cooler sp140 fans are set to performance mode which is about the same rpms using Corsair link utility.

Alan, can you find them in a 140 mm version ?

I think they would fit nice. Then I could attach my Corsair LED`s I ordered to the bottom of the rad and put the thin ones on the top.

I bought one Scythe but never again; the airflow rating was exaggerated and the noise level rating was understated.
