What app are you guys using to measure the temp of your video cards?

[Ichigo]

I'd like to use it too.

The built in section of the drivers.
Not all cards support temperature readings.
ATi 9800XT and later cards do AFAIK, the Geforce 6xxx and later do, not sure about any earlier nVidia cards, or budget ATi card, but the high end from both from th elast 2 generations has supported tem preadings shown in drivers.

Didn't find it in drivers, but found an option in AtiTool. =p
