Recently I decided to build a new rig (see sig for details) and after doing a lot of reading decided on the Thermalright Ultra 120 with the medium speed S-FLEX fan (120mm, 49CFM, 20dBA) for my E6300. My problem is that the temperatures I'm seeing with this setup seem high to me given what I've read in reviews and posts.
Idle is 38C as reported by CoreTemp 0.95, ambient temperature is about 68F. Currently the components are sitting on boxes on the floor with no case, open to the air on all sides. There's a slight breeze in my room due to an open patio door.
Running Orthos Small FFTs test, the temperature shoots up to 60C within 2-3 seconds. Over the next minute, it gradually climbs from 60 to 62. At 10 minutes it rises to 65, and at 20 minutes it hits 66. These temperatures seem really high to me, especially with other people reporting mid 40's under load, and the fact that I've barely raised the Vcore at all (+0.025 from stock).
I've tried reapplying the thermal paste several times, first using the stuff that it shipped with (some white goop) then using some Vantec Copper Ice and finally twice with Arctic Silver 5 (the second time with an even thinner and more even application). None of it made any difference.
One thing I've noticed is that the heat spreader on the CPU has left a slight outline on the bottom of the heatsink, which leads me to suspect that the heat spreader is very slightly concave, but it's nothing that you can see visually. I put a drop of isopropyl alcohol on the center of the CPU and placed the heatsink on top then removed it, and there was liquid spread over the entire contact area, so I don't think that's the cause.
What should I do to try to track down the cause of these temperatures? Any advice would be appreciated!
