I had two 80mm fans in the front of the case, blowing air in and the I had an 80mm exhaust fan as well. My PSU has two fans, one sucking air in on the underside of the PSU and one blowing out as exaust. I also had a side case fan, I also have a manually speed controlled fan on the cpu, and my case temps were at about 34C to 36C, and CPU at around 40-43C (no load) my hard drive temp fluctuates between 30 and 37C also.
I removed both fans blowing air in at the front of the case, and the side fan, leaving only the PSU fans, because those obviously can't be removed, and the exhaust 80mm fan, and CPU fan. My temps read basically the same, no real change. If I turn up the manually controlled fan I can get the temp on the CPU to drop to about 38C (no load), but it is way too loud, sounds like an airplane, but case temps stay the same.
In my older comp which has the socket 478 the case temps are around 25C and CPU temp at about 32C, and it only has a cpu fan and one 80mm exhaust fan, oh and also the PSU exhaust fan. I just don't get it.
Do I need to add a bigger exhaust fan like 120mm and a 120mm blower fan in the front?
Any help would be appreciated.
