So my 4-month-old Core i7-920 has been overheating recently. It's nothing drastic but it's enough to make me think something is wrong. When the PC is sitting in the BIOS, the CPU temp hovers around 46C. When I first boot up and it's sitting idle in Windows, I get temps around 55C on CoreTemp. A couple minutes later the loads start jumping all over the place and the temps jump up to the 60C-70C range. This is when I'm doing nothing more than using Firefox and CoreTemp.

The inside of the computer looked a bit dusty so I bought some compressed air and blew out all the dust, but that made little difference. Fans are all spinning. The heatsink is locked firmly in place. I don't overclock. Ambient room temp is 24C. Even with the side of the computer case off the temps only drop 2 or 3 degrees. And I don't know if this is relevant, but my GPU fan has been running loudly as of late.
My next step is to buy some new thermal grease and reseat the heatsink, and if that doesn't work maybe buy an aftermarket cooler. Before I start shelling out cash, however, I wanted to get some expert opinions from here and see if there is a simpler solution to my problem.
