I just upgrade my mac from a T2300 to a T2600, I applied the thermal paste pretty good but with the heatsink just having 3 plastic pins that hold it down instead of 4(one broke) im kinda worried about it overheating. It's been running great for almost 2 hours now (while installing the mac os x disc)....well is there a way I could view the temperature of the cpu (instead of waiting for my mac to shutdown unexpectedly)?
