My ThinkPad is not engaging the fans like it should (Or so I think). I can feel the heat coming out of the exhaust and it sounds like the fans are running, however with increased load it doesn't speed up. The system got up to 81C while play MineCraft (I know there are problems with it not being optimised just giving details) and the fans never kicked into high gear like they would on Windows.

My specs are:

Processor: Intel® Core™ i7-2640M CPU @ 2.80GHz × 4 (It was a debate between dual and quad, still not sure if it was the right decision)

Graphics: Quadro 2000M/PCIe/SSE2

Memory: 7.8 GiB

Does anyone know some good software for controlling fans, or if this is a driver issue, or anything of that sort I would be very happy!
