Standard rule is side and front in, rear out. It's somewhat beneficial to have high pressure in the system so the air will circulate before it leaves. Equal intake and out-take is normally fine, but can cause some hotspots where air isn't circulating since all the air coming in immediately leaves. Negative pressure will definitely cause some hotspots, and may even bring more dust into your case (debatable).

so the fan on the front should be smaller then the one on the back?

Larger (well technically, just one that moves more air).

so the front one should be larger? I thought the point was to get the hot air out faster then getting air in?

The problem with that is the air wont circulate around your case. While this is good for anything in the way of the airflow, the GPU is typically set at the back lower section of the PC, and without some circulation you'll actually have less effective cooling.

Which way would cool the GPU better, I usually have cooling problems with those. My CPU now running what I said before is running at 15 C.

How is that even possible? How cold is your house? 15c is around 55f.

house is 68 F, maybe core temp is off, now it is saying both cores are 11 C. Thanks for the advice, will have to save it. Guess 80mm on back 90mm on front. up to 17.

What are you using to monitor the temps? Are you looking at the temps in the BIOS or software that came or was made for the motherboard? If you're using third party software to monitor the temps, there's a chance that it's listing the CPU temp as something else, or it could just be flat out wrong.


Like I said, just stay away from fanless video card models. The GPU will have it's own fan, it'll cool itself just fine. And depending on the model, it probably wont add any heat to the case. A lot of the higher end video cards have their own air duct and exhaust heat from the video card directly out of the case. Even when they don't, they should add too much heat to the case, if any at all.

I am using core temp. version 1.3
