Well im sure the thermal paste in the x360 not even close to as good as Arctic Silver 5. From my own PC overclocking experiences I know how good it is. Infact, opening up teh X360 I can see the obvious cooling problems ...
... question is, is it easily openable. I know opening the X360 to a motherboard state takes under 5 mins if you have the kit. Infact, when I got this console, it was opened for me to check using a X360 opening kit ... and took that time.
When I say easily openable, I mean is the GPU and CPU heatsink easily removable or not ?
Otherwise, I had another idea ... putting a heatshield between the GPU and the DVD drive will prevent the drive heat from going towards the GPU aswell. Ill do some research and rip this thing apart after exams and do some mods to help in heat control and circulation.
