Best method for me?

post #1 of 7
Thread Starter 
Im wondering whats the best method for setting up my fans. I have a Phantom case with two 200mm fans up top, a 200m on the side, 120mm on the bottom right, and a 120mm in the front and back. At the back i have a rad for my cpu cooling with push pull. Atm the top 200mm fans are setup to be exhaust ports, the side 200mm blows air towards the mobo/top graphics card (im running 6950 crossfired and the bottom gpu runs 5c hotter so i dont think the fan is really blowing air at it), the bottom side 120mm pulls air out since i have a feeling their is a air pocket their and the front 120mm blows air into the case. Is this the best method or should i switch the fans so the top two are intakes and the side is the exhaust. One thing to note my case is by a wall so the intake meaning the intake fan is faxing a wall.

However it works out to have intake low and in the front and exhaust high or out the back.

You said your side intake is near a wall, I wouldn't even bother hooking it up. It is not going to pull much air in, and would probably mess up the air flow lines inside the case.

my side intake fan is maybe around a foot from the wall, guess ill play some game see how my temps are then switch them and also look at the temps and see which is best.

The only means to determine what works best is by careful testing as each application is different.

Here is a very old (by internet standards) article on fan placement and air flows: PC airflow and heat – a cooling guide

(Im glad I found the article. I have referred to it often over the years but was never able to find it before)

^^^^^ The airflow guide is exactly what I have told people over and over... The only means to tell what works for your PC case and hardware is to actually test. Different cases, HSFs, hardware, fans, etc. produce different results.

For those with a clear PC case side panel, you can use yarn tufts to actually see where the air is flowing, which can help with how you use your fans for best cooling. Cardboard or plastic air deflectors can also direct the air where needed for improved cooling.

Too many fans creates a lot of turbulence that prevents good air flow thru the case to remove the heat and bring in cooler air.

well i played some bf3 since its the most demanding game i got atm and the hottest my cards got were 65c. Switched the fans and the hottest they got were 62-63c so looks like having the top two fans as intakes are kinda batter.
