Possible bug in temperature reading (gtx470)

There seems to be some kind of a "bug" in the gpu-z 0.4.4 reading GPU core temperature. A picture is worth more than lots of words, so:



The (GPU core) temp jumps from 49°C to 80°C and shows no temps in between, as you can see. This happens also when temps are going down after shutting down a 3d app. Other measurements seem to be ok and "real-time", like the fan-rpm and fan-%. HWMonitor does not seem to have similar problem, so I'm guessing it's GPU-Z related.


GPU-Z says the card's (Zotac GTX470) bios version is 70.00.1A.00.03 and the drivers are 258.96 WHQL (Win7 x64).

Have you tried any other software?
Yeah, but only HWMonitor so far like I said.

To be a bit more precise, the problem is not "just" going from 49°C to 80°C, the reading can hang at any given temperature, and then change after a while.

It seems so, yes. GPU temp jumped from 59°C to 67°C when I increased the GPU load a lot. I removed the load and GPU-Z kept showing 67°C for over a minute, then it dropped to 64°C.
