Hey guys, just got my MSI 790FX-GD70 two days ago and spent the last day and a half putting my rig together/troubleshooting it.
Despite the fact I'm now an owner, I have no specs to apply for membership since... well, I'm not sure I'm an owner of a functional board. The temperatures with my rig have been far too high. They're not going to damage anything, but I'm wondering if I have a sensor issue. The reason I first suspected, was because upon booting into the bios (directly from a state of inactivity) my cpu temp read 39 C /102F and system temp was 37 C / 98 F. This was with a Zalman CNPS 9700 NT
. Note that my ambient room temperature was 23C/73F.
After seeing this, I performed several tests. I also seem to have one of those nearly overheating Northbridges, though since I'm worried about the Mobos temp sensors, I'm not going to bother trying to take off the heatsink quite yet to fix that.
So back to the tests: I realized I could be doing something wrong in regards to my application of the zalman cooler (though the high system temperature seemed to indicate otherwise.) So I removed the Zalman and stuck on my phenom II x4 955's stock cooler. I then proceeded to see a 37C CPU temp, and 27C system temp immediately upon startup. (This was a cold startup, and my room was/is 21C. I should note that I have an Antec 1200 with the optional fans installed. It's a beast, and I set a thermometer in the case near the mobo. Temp shown is the same as the temp outside the case.
After letting the stock cooler sit in bios for a few minutes, the temps rose steadily to 43C (CPU) and 37C (System) before apparently stabilizing.
Here's screens of my tests in Everest for the temps of the Stock cooler vs. Zalman Cooler:
Any thoughts on the matter? Advice? Etc? I've tried this with both BIOS version 1.6 (came with mobo) and 1.8. No differences.
My thought is that the sensors are just messed up due to the system temps, and the fact that my listed core temps are lower than my listed cpu temps. If anyone has any theories, or possible solutions, let me know please. Or hell, even if there's somewhere else I should post this
. Going to see what people think before calling AMD or MSI tech support. Would hate to spend hours on the phone with AMD if it happened to be a mobo thing.
Appreciate any help I get. Thanks.
 I should also note that I can feel heat when I touch the heatsink. It's almost unnoticeably different though. It's not hot by any means though. In fact, It's barely above case temp. Haven't tried touching it under load with stock cooler though.
And no, my phenom is not overclocked.
