Heatsink compound and warranty?

Hey guys,

Recently my T520's been overheating when I play games. I know its not a gaming laptop, but at the beginning I had no trouble paying bf3 on min settings and other games ran fine.
Recently though, after 10 minutes, the gpu temp reaches 94 degrees and gets throttled down to the abyss.

I'm just wondering if replacing the heatsink compound with some arctic silver wil help, and if doing so will void the warranty, I know basic maintenance and changing arts is alright, but this is a lot more invasive.

I've tried everything I can think of as far as playing with fan settings, I've dusted out the vents, and that didn't help.

 

It may help, but will also void the warranty. If it's still under warranty, why not call support and ask them why it's running so hot.

 

Depending on the GPU, 94C isn't that hot. 94C for the CPU, however, is.

Yes, but probably not a huge amount (unless the existing application is wildly defective.)

If you screw up something while you do it, yes, it will.

What GPU do you have? And what are your CPU temperatures both at idle and after a few minutes at full utilization?

And ZaZ has the right idea: if it's under warranty call support and talk to them. That's why support exists!
