I know this isn't related. But how can I cool my HP G61'S laptop memory down? the HDD and Memory (RAM) feel about 60degree's which can't be good. Its burning my legs.

Put it on a table and raise the back end up so that the fan(s) can work properly to keep it cool! It's being sufficated.

I keep the fan clear, i've had issues with this before. EVEN on a table... the cpu got 100degree's and the fan has not even linked in any way to the memory and the hard-drive. To be honest, the fan isn't even close to it.
