P650HS Liquid Metal Paste Expired?

Recently my P650HS-G has been firing up even on idle. Around 60-70 for CPU when idle, and about 90 and sometimes 95 when playing PUBG and War Thunder, both max graphics. Once I was playing War Thunder, my computer crashed, making buzzing sound, monitor glitching out, and I couldn't check the temperature, but I believe it was very hot, even on plastic outer surface on keyboard.

I purchased from GenTechPC 1 year and 7 months ago, and added option to use Coollaboratory Liquid Ultra. Is it time for repaste? If so, should I switch out to MX-4? (I got 2 of the syringes)

 

Well, any paste is better than an overheating CPU.

 

True, but I would like to know if Liquid Ultra expires after 1.6 years

 

I've heard of it either spilling out or reacting chemically and evaporating.

 

Alright, what is the best procedure of removing Liquid Ultra from laptop?

 

Carefully with alcohol and cotton buds or pads.

 

Have you tried cleaning out the fan grills, could be the case of them getting blocked on the inside of the fan, not really noticeable unless you unscrew the fan from the heatsink. Compressed air should blast it out.

my p670 was overheating and I had small carpet but not as bad as you on idle

 

Good point, shine a light through and make sure it looks clear.

 

I opened up the bottom and cleaned out the visible dust, not the internal fan. Thanks for letting me know.

 

It could have fully sunk into the pores and become much less liquid to the eye. Sort of bonds with the metals after a while from my experience and then becomes much less paste. You just maybe need to add a tiniest drop. But if you repaste with something else, you have to completely clean it up, which might not be as easy as it seems.

 

I have been using this laptop actively, almost 4 hour every day on average. If that happens what would be the best way to clean?

 

the best thing is to use more LM to fix it. Otherwise your gonna need the good stuff to clean it, and it might permanently be "stained" or so it will look. It might affect performance too switching pastes, but I have never tested that to be honest, just being hypothetical.

 

If you switch out, please opt for Thermal Grizzly kryonaut and not MX-4. The latter is okay, but expect up to 5C more under load with MX-4. Undervolting CPU and GPU plus repaste would be my advice.

 

Kryonaut does have higher thermal conductivity than MX-4. Of course everyone's mileage varies, though.

 

IC diamond does have a funny smell when removing it I have found, krynaught offers the same performance without that and the scratching.

The other option is to regenerate your current application with a tiny drop extra.

 

Sorry for late reply because I have been busy and was confused on either remove the LM and go for MX4 (budget issue), or repaste with another LM (don't have one cuz GenTech applied it)

These days i was in 65c idle

 

Did you double check the fit and contact is still good? LM does not need a repaste every time you remove the cooler.

 

I was able to check a bare inside because my screw for heatsink came as stripped. With a small swipe with swab, it was literally particles of metal, looks like a bit oxidized

 

It can develop a sheen but should be fine.

 

I repasted successfully, temperature went down in 50C CPU and 48C GPU.

But I have a question: What is this black clunk in the middle whilst cleaning?

 

Weakness leaving the core.

 

Contamination.
