Can I change the cooling paste on my CPU without voiding my warranty?

So my T450s is sometimes running relatively high tempearture, so I was thinking of applying new cooling paste. But will this void the warranty? Can I replace my keyboard as well, without voiding the warranty?

How high?  A relatively new machine will not normally need new paste.  Has it been disassembled?  The new fans come with paste applied in tiny dots and they can get better coverage than you usually can with manually applied paste.

Idle is around 35 C. 

Browsing Chrome with some tabs 40-44 C. 

Wathcing videos/streaming in HD gives temperature around 65 C+, sometimes 70 C with multiple Twitch streams. 

 

So it's really only a problem when streaming in HD. I read the temperature test of the T450s on Notebookcheck which showed much lower temperatures during benchmark tests. My PC has not been disassembled - but that's only because I worry that about the On Site warranty being voided. 

Maybe disabling Intel SpeedStep would help with the temperature?

I think your temperatures are fine.  I think changing the paste wouldn't help, and if you get poorer coverage on the paste, it may hurt.

OK thanks. Still unsure what I'm allowed to do, without voiding the warranty

And we're back...
