What TIMs are used in laptop cooling?

[Skree]

As per thread title really. Was just wondering what kind of TIMs are used between the heatsink and any chips it's on in typical laptops.. I'm presuming it'll be thermal pads rather than the white goop you used to see a long long time ago on mass made stuff..

Don't really want to take my Samsung R20 apart just to find out, while it's still in warranty but am wondering if it'll be worth upgrading the TIM to AS5 or even if it's easy - have heard some heatsink retainers are designed with pads in mind.. just a thought coming from an old head at fixed pc stuff but relative n00b to laptops...

No it is in warranty, and isn't overheating. But i use this laptop a LOT (it's on pretty much 24/7 at the mo) and i was thinking about minimising temperatures within it. I've always tried to do so on PCs i've built myself, which is very possibly why all my 24/7 on machines last a long time. I still have a P2-350 in 24/7 usage, and have a couple of early P1 systems in bits in my spares boxes that are fully working. Even a difference of a couple of c is worth it.. Not worth invalidating the (two year, commencing mid july 07) warranty for though.
