changing brand new laptop's thermal paste

[thib.g]

hi everyone , i bought a Lenovo idea pad 330s ( ryzen 5 2500u version) about a month ago and i want it to be as quiet as possible so i thought about changing the termal paste.

i already opened it to add 4 gigs of ram so there's no problem for that part.

the thermal paste i'll be using is the Cooler Master IC Essential E1 (i have it laying around) .

is it worth it , what temp temp decrease should i expect and is liquid metal (and coating) worth the extra cost ?

Lenovo usually uses really high quality thermal paste so the temperature difference may be within margin of error. Bob of All Trades on YouTube made a good video about a Lenovo laptop's thermal paste and performance, and I'd assume they probably use the same paste on all their laptops. Do NOT use liquid metal. If you're careful its fine for benchmarking, but please do not use it on a regular every day machine. You'd have to replace it every so often (probably twice a year or so but don't quote me) and thats assuming it doesn't leak out over time an kill your laptop completely. Also, welcome to the forum!

That is only applicable for Legion Y740

I suggest using a higher quality paste, but this will be better than stock too

Well, I got the "don't use liquid metal" part right. 1/3 ain't bad.

That's true. Liquid metal is nasty stuff. It still reacts with copper albeit at a much slower pace. It is fun to use to melt metal items, but I wont ever put it on electronics that I plan to keep. 

 

It doesnt need to be replaced as often as you said though. A good application should hold up for 1-2 years. Honestly better than most performance non conductive pastes. The major caveat being it eventually will ruin everything it touches.

Quite the caveat
