    My vpcz1 have cooling issues. Usual things, such as surfing the internet or watching youtube, spin the single fan to its maximum, so laptop becomes too noisy. Sometimes it even turns off because of overheating. Laptop was cleaned from dust. Should i try to replace paste with liquid metal (Coollaboratory Liquid Pro or Thermal Grizzly Conductonaut)? Btw cpu and gpu have thermal pads. Sorry for bad english. [​IMG]

    There's nothing as good as liquid metal (cheaper option: 10x more for the same value).

    Only thing is whether you're confident enough and can be bothered to tape off the exposed interface dots on the cpu and gpu. Heatsink is copper, so that's great. And the cut-to-size pads make a perfect dam, so your system looks like it was designed with lm in mind :vbsmile: .

    Quirky system, btw; an ultrabook with VGA and DVD plus a physical MUX switch and a DVD eject key ... this laptop is weird! It does explain that crazily cramped motherboard.

    Thank you very much for the answer. i`ve heard about some situations, when copper heatsink absorbs liquid metal after long time. Is it true? i dont want to repaste it every time

    Yes, a little. It'll react a bit at the surface and cause discoloration of the copper. It won't affect performance though (more like the reverse) and you'll never have to repaste either way; lm is a one-time thing, unlike every other type of paste.

    Sometime have to remove heatsinks in order to swap cpu or gpu and the liquid metal is always in perfect order (liquid, that is), so just even it out a bit and re-attach heatsink without the usual clean and repaste.
