Desktop Airflow.

Hello, right now i'm having trouble with a failing cpu and video card. Until Tuesday I won't get my replacements in the mail, and I'm just wondering if anyone can help me out with some techniques for my case. I've tried the positive pressure airflow technique to the best of my knowledge and it seems like my idol temp for my video card raised from 40-45c(without the side case and fan on) to above 50c(with the positive airflow).

I have this case which includes two 250mm fans. One in the front that doesn't do much(It's actually not spinning anymore and if it does it makes scraping noises).

And the other 250mm fan on the removable side. THIS FAN BLOWS INTO THE CASE. They both also have controls for the speed of the fans.

The second fan I'm using for PULLING HEAT OUT OF THE CASE is a standard 120s fan I got from a thrift store.

^^^^^^^(google picture of same model Fan) ^^^^^^^

Any help is really appreciated. For more info my pc make up is:

  1. sounds like you need to replace the front fan first so it helps cool better,i think with 2 250mm intake and one exhaust of 120mm this may be too much positive pressure,you can run 0ne of these 250mm intakes,if you are using both,you can remove a few pci covers at the back of the case to help vent some of the pressure in the case
  2. The 120mm fan is on the back I didn't really specify that. I will try to get the front one working, but even when looking inside the case, most of the drive bays are attached to a sheet of metal attached to the front/inside of the pc. Not much room for air to flow to reach the front fan but I could be wrong.
  3. and the smaller fan has no speed control that I can see/know of.
