Not sure if this should be in water cooling or air cooling…Note:
These tests were to find the best possible position/temps for my case/setup before remounting. Temps are worse after moving to new mobo and going from stock paste to mx-2. Will be remounting soon.Flaw in testing methodology:
I have nothing to record ambient temps but house does run AC on 77F/25C. My room is the hottest in the house and is normally 79-81F/26.1-27.2C in the summer day or night.
Tested 8 different fan/radiator setups using the Antec Kuhler 620 with stock fan in CM690II Advanced B&W. 20min Prime95 Blend runs recorded using Open HW Monitor.
Tmp#1=random mobo sensor
955 @ 4ghz 1.488v load 1.456v idle 1.072v power saver idle
Cpu-nb stock 2ghz 1.1v
Results are listed from WORST to BEST based on MAX CPU CORE temp
Result 1: 63C Very stupid setup... Just shows how your fans are setup make a big difference. Refer to Result 4 for comparison.
Result 2: 61C Thought this result would be better than Result 3 due to recycling hot exhaust back into radiator. Apparently not.
Result 3: 60C
Result 4: 58C
Result 5: 57C Seems to be recycling warm exhaust. Look at Result 7 for comparison.
Result 6: 56.5C Not bad but would prefer to not intake from the rear... no dust filtration.
Result 7: 55.5C Not bad result but the antec fan is loudest when mounted vertically in the top as intake as compared to horizontally mounted.
Result 8: 54.9C and 54.8C. These two tests were taken on two separate days and should show that ambient temps and overall testing methodology were fairly consistent. The only difference was the side intake fan.
How it looks inside the case:
