Is my fan setup ok?

post #1 of 11
Thread Starter 
Hello,

So i have my computer for some time now, but recently i started thinking if my fan setup is alright, especially my cpu cooler, im debating whether to push/pull it, and to mount it horizontal.



This is my setup now.

My GPU is a non-reference, so it exhausts most of its air in the case.

I also have a 200mm side intake, which im thinking of getting rid of, because it might just disturb the airflow, and replace the mesh with some plexi biggrin.gif

So my question is, is there anything i can do to get my airflow better? me temps arent that bad, but i think they can be better.

What is the distance between GPU and face of CPU fan intake?

If you remove side intake fan you will need to get air into case from somewhere else. wink.gif
I believe in more intake than exhaust because it lets less dust in.. assuming all intakes are filtered.
I have 3x 140mm intakes (TY-140). No exhaust fans. biggrin.gif

I have two 120MM AF120s exhausting from the top, and one NZXT stock fan for the rear.
I have an NF F12 pulling air in from the front along with a stock CM fan.
I plan to get some fan filters so that dust doesn't get inside my rig.

So 2x fans intake and 3x fans exhaust.

3x exhaust fans will be trying to pull more air out of case than 2x filtered intakes are pushing.

Result:
Air will be sucked into case through any/all places air can come in through. This means optical drives, case seams, USB ports, power switch, etc. will start collecting dust/fuze.

Above is the reason I suggest designing so total intake fan airflow is rated higher than total exhaust airflow.

End result regardless is "what goes out must come in" / "what goes in must come out" .. except dust biggrin.gif

All of my intakes have filters (come to think of it, its been half a year since ive cleaned them.... whoops)

@doyll, when i get home, ill check what the distance between the heatsink and gpu is.

So, if i remove my side intake, is it a good idea to put my front top intake upside down, so it sucks air in?

Filters need to be cleaned every week or 2. These fans loose airflow even with clean filters.. like 20%.

No. That would only create a fuster cluck FUBAR.

Airflow is not "3 fans in and 2 fans out."
You want the air to flow smoothly with no abrupt changes in direction or it scattering in all directions. wink.gif
You need to visualize how the air is moving through your case... and that's not easy to do... even harder to show. I searched You Tube and can't find a single good airflow.
This is the best I could find. Think of the AP121 as the best at "flowing" air and T.B.Silence and Sickleflow 120 as best at "blowing" air.

In your case front and side in with top and back out.

The back exhaust is doing very little if anything. it might be helping move air between motherboard and CPU cooler and maybe not even that.

Yeah, i guess that makes sense. So i have my pc apart now (to do some cable management) and also to install another fan on my heatsink for a push/pull, and to change my paste to something that has a name.

Also, there probably is about 5-6 cm of space between my heatsink (about 4 with another fan on it) and my gpu. Would this be ok?

5-6cm.. 4cmwith another fan... fans are 2.5cm. doh.gif I'm confused. Are you putting 2 fans on intake? I would put one on intake and one on exhaust of cooler.

Rule of thumb is area of fan <= area of airflow to fan. So 140mm fan has 154 sq. cm are with 1/2 of fan circumference + fan diameter. So 22cm + 14cm x 4cm = 180 sq.cm 154 < 180. Over simplified. Hope that helps.

Im just putting 2 fans on my heatsink wink.gif

Also, i calculated my intake and exhaust, and they roughly match thumb.gif
