It was cold in this room when I got up and came in. Not below zero (that's ice crystal time!), but cold enough that the case felt like ice.

So you're saying it defies the laws of physics?

Pics of a room thermometer in your room or it didn't happen.

First, it's a "stuck sensor" (nope).
Second, the room can't be too cold. (nope)
Third, now "pics of the room thermometer" are needed.

Now if I knew that the temps were that cold BEFORE I turned off the AC and started doing other things which raised the temps again -- I would've gotten more evidence! But it took a stray look at the HWmonitor to even notice the temps got that low (I'm using it to monitor how hot the GPU core gets, not how cold it can get to [as with folding that's not even an issue!!]. lololol

BTW, about the law of thermaldynamics: my room is my room, it defies explanation how and why what is "normal" to keep things cool doesn't work. Tech relative used to argue "that can't happen" as you guys , until he saw it himself that the cooling I had (7 80mm fans for a stock run system) wasn't enough, even with the AC.

Well you could take a picture of the temperature. Reading over the thread, sounds like this process is repeatable. Nothing like verification! I'm curious as to the temperature in your room mainly to achieve such temps, if at all possible.

A GPU temp of 7C, idle or not, would require a room temperature of around 0C at the warmest. There's no way a simple AC can make the temperature drop that low. It's typical inaccurate sensors.

Would people stop saying that this is impossible, he already stated that the AC had been running at maximum for a long time, so the room was very cold, and assuming that the ambient was less than 7C (which is quite possible) there are no laws of physics, thermodynamics, etc. being broken.

I'm not saying its impossible, but I would just like some more evidence is all. Why would you be against the inquiry of people he wanted to share this with?

noobpower2 · 03-20-09

just log all the temps on graphs through rivatuner and come back with the results. according to your picture you maxed like 76 and currently at 69. if you were right you'd see the core temps gradually dipping to 7, if not the sensor malfunctioned.

I'm not, I'm mainly speaking to the people who just say that is is completely impossible, no matter what.

A GPU on stock cooling (especially a GPU like the 4870), no matter what the fan speed, does not get that close to ambient temperature. It just doesn't happen. As I said, the room would have to be below freezing for those temperatures to be plausible.
And what about the CPU? Why isn't it about the same temp if it's just sitting there idle? CPUs can usually get much closer to ambient on air cooling than a GPU that's simply on stock cooling.
