I have the following PC configuration and since September 2011 when I bought and assembled it the only maintenance I did was cleaning every fans with compressed air.

Now we come to the part I care the most. I have monitored my GPU temperatures lastly, especially during playing a new game (requirements here) when the two fans under it start running very fast, something never happened to me before.
The idle temperatures for my CPU are around 35-40 C, while during the game are around 50-55 C. For the GPU, idle temperature resides around 50-60 C, and during the game hit up to 80-85 C. My GPU is not under/overclocked, I never touched MSI Afterburner because I don't know well how it works and never needed it.
I know I should not be scared because the maximum declared temperature for the GTX 580 from Nvidia is 97 C, but still I think that looking at the requirements of games like the one linked above, it shouldn't reach this temperature and the fans shouldn't start spinning and causing noise like this.
I use dual monitor with different frequency (120 Hz main monitor in DVI, 60 Hz secondary monitor in VGA adapted from DVI)
Now comes the real question: A friend of mine at work suggested me to change the stock thermal compound on the processor of my GPU since I never did it. Do you suggest me to do the same? Have you got any suggestion to achieve this without causing troubles? Right in this moment, I got in my hands an ARCTIC MX-2 (4g) Non-Electricity Conductive, Non-Capacitive and Carbon-Based Thermal Compound.
