I have a heavily modified Compaq SR1717cl and I'm starting to think my cooling setup isn't doing what it should. The case itself has sets of holes on the side panel up near the power supply, adjacent to the cpu (big holes there) and another spot at the bottom right corner near the front under where the HD is. There is no space or hole for an intake fan in the front and I can't put one there because all the connectors for the front panel LEDs are there.
As of now I have a fan mounted in the rear drawing air out and a doublesize slot fan mounted below my video card drawing air in and onto my video card heatsink.
After doing some very rudimentary tests (holding a cigarette in various places to visualize airflow) I found that the aeration holes in the side of the case were causing "air short-circuits". The fan in the rear of the case was drawing air not from inside the PC, but right through the holes in the side of the case and out the back.
So I got some duct tape (If you can't duck it, **** it amirite?) and covered all the holes except for the small grouping in the far corner and I seem to get better airflow (at least it's not coming in the side and right out the back anymore) but I'm wondering if the intake in the back from the video card cooler is countering the main case exhaust fan and keeping it from pulling air through the vent holes in the front and through the case.. as I'm not seeing any real air movement in the front there. The air may just be making a short loop from the intake past the video card and right out the back and that could be bad. My temps are fine but.. I'm a perfectionist.. Any suggestions? Would a small fan mounted near the vent I left open near the front help pull some air through the case?
And is it just me or are the companies who put holes in the side panel and then also supply you with a mount in the rear for an additional fan just not thinking at all?
