So, it's the rig in my signature. Phenom II 940. currently @ 3.5ghz and 1.4875v. It's being cooled by a Sunbeam Core Contact Freezer 120mm. The cooler has a manual speed dial, and I've tested it on "low" and "High" Unfortunately, my temperatures seem painfully high. Running an OCCT stress test I get to 64*C on high, and 73* on low. What's really odd is that I'm idling at 51* on high and 53* on low.

Now I know that I'm putting out a lot of heat, (180w if my math is right) but it doesn't seem like the heat sink is being overwhelmed. The top is barely warm to the touch during these runs. It also *SHOULD* be doing much better with these temperatures. According to Frostytech on a 150w intel system they saw increases of 16.1* over ambient on high, and 21.2* on low, which in my 25* apartment would put me at about 41* on high and 46* on low. Both of these are lower than my idle temperatures, so clearly something's wrong.

I'm running with the case open, so it's not a case airflow issue. I've re-mounted the heatsink 4 times using three different paste application methods (dot, lines on the pipes and spread with a ziplock bag.) I've used both AC-5, and the Zalman paste, and when i pull it off every time it looked like the paste was on right.

I'm pretty much out of things that I can think of trying. I'm sure that something's wrong because if nothing else, then I shouldn't be idling that high. the only things that i can still think of is that something's wrong with the heatsink (heat pipes not under vacuum like they're supposed to be?) or that the cpu/board isn't reporting the correct temperatures to me. Is there anything at all that I'm missing?

Edit: could someone fix the thread title please?

Sounds like cool and quiet is off in your bios, you might try making sure its on as you should be in the 20c range idle even with that voltage.

The chip is a POS to be honest. It NEEDS that much voltage to be stable @ 3.5. It crashes if the voltage is even .0125 lower. The thing won't even hit 3.2 on stock voltage. It's also an older cheap board (ASRock A780FullHD) which does not support CnQ as far as I know. My issue is that even with these kinds of voltages I shouldn't be seeing these kinds of temperatures. an IDLE of 50*+ is just crazy with the giant hunk of copper and alluminum that I've got strapped to the lid of that CPU.

Anyways, maybe it's that cooler? Is the BIOS using smartfan or something else that's not making the fan go to faster RPM?

The cooler is supposed to be one of the best out there. It's a 120mm tower cooler made up of 1.3lbs of copper and aluminum. The fan speed control is a manual knob coming from a 3 pin header, so the mobo isn't playing with fanspeeds on me.
