According to MSI, my X2 CPU is running at -10C using the stock heatsink/fan, despite it being 29C in the rest of the case. It must be only a matter of time before the rest of the case cools down and the whole thing becomes a block of ice. However with my apartment a/c running maybe I can keep it dry.
I had the a/c running all day while I was sleeping, and it was raining and cool outside so it got really cold in the apartment (68F according to my fridge thermometer sitting on my desk), I wanted to see how that was affecting my computer temps, how much of that cool air was getting in there. Normally it runs at about 43 to 45 when the apartment is just in the tolerable warm range. I found that the laws of physics had broken down inside the case.
So, apparently the CPU was at 12 degrees Fahrenheit. Touching the heatsink certainly seemed warmer than that. Maybe I need to put better thermal goop on there. MSI's CoreCenter unfortunately doesn't give readings in F so I had to convert using the calculation.
Anyway I shut down to see what the BIOS hardware monitor actually said. Apparently my house isn't about to fall into a spacetime rift, it's just a BIOS/monitoring bug. It was reading -10C/50F. Calculations show that 50F is actually +10C. Of course even that is impossible given the temperature of the air in the apartment and the rest of the case.
I'm not sure if there's a threshold where the readings suddenly jump 30 degrees, or if they just slowly got less and less accurate as it got cooler, going down by 2 degrees for each 1 actual degree, then 3 for 1, then 4 for 1, etc. Running two session of Prime95 has only managed to get the CPU back up to +1C in CoreCenter. I'll see what happens as the apartment warms up now that the a/c is off.
Just goes to show how unreliable and inaccurate temperature monitoring is. If I took the 50F reading from my BIOS, that's 15 degrees minimum difference between what the BIOS showed and what the actual air temperature was, which would be the minimum CPU temperature. So my usual 45C readings might actually be as high as 60C depending on what degree of inaccuracy there is as the temperature rises. The 56C 100% load readings I was getting might have been 71C or more! Am I concerned though? Not really; the system doesn't crash and Prime95 doesn't get any errors, so I'm all good.
