I got this issue quite often with my gtx 560 ti. This issue happened with the 3 latest drivers and beta drivers(haven't other drivers). Hope nVidia will fix this.
Hi, i have 2 ideas (dunno if it`s existant or not) about showing the temperature of your component.
1. Put/spary/paint some thermochromic paint(transparent and change to red at let's say...40 dg) on the key component like gpu's fan, cpu's fan. These paint will actually alarm you of any...
