Repeating my Clevo/Sager and found this :(

My temps haven't been great on the laptop. Nothing way out of line, but I'd like to get them into the 80s while gaming.

I cleaned the fans of dust, no change. So I decided to repaste, and I'm a bit troubled about the state of my CPU die and heatsink.

They both seem to have some sort of scorch Mark or smudging on them.

Am I screwed?

Did it come with IC diamond? If so, you might've just scrubbed it off and scratched the die/heatsink.

It is recommended to wait 45s-1m for alcohol to weaken the IC diamond, then you scrape it off very gently. Repeat until no thermal paste is left.

 

I have no idea. But I don't think that's what happened, you can see where a very similar shape is on the heatsink copper, note it's upside down in comparison.

Is there any way to fix this?

 

This is nothing to worry about. I would just apply some fresh thermal paste and forget about it. The paste will fill the imperfections in the scratched area. I suspect someone repasted it and applied too much back and forth pressure on the heatsink trying to spread the paste which caused these scratches. Even if the paste was not abrasive, enough back and forth pressure where the copper meets the silicon will cause scratches and scuffs. I would only worry if the silicon gets chipped, which does not appear to be the case with yours.

 

Agreed, just apply new thermal paste and forget it.. Nothing has happened from the looks of it, everything should work fine just some surface scratches..

 

Thanks everyone. I think the previous paste job was actually overpasted.

It glooped over on one side pretty nastily.

I'm pretty sure the job I just cleaned was MX4, but the original may have been AS5

I would look at liquid metal pastes like Coolaboratory Liquid Ultra or Thermal Grizzly Conductonaut. Should drop your temps significantly under load. Conductonaut, which I use, dropped my load temps by around 10 degrees C with my 920xm.

 

Not required for OP and honestly, you need to be a pro to apply it or you'll fry your laptop.. Not worth the risk..

 

You're probably right, especially with a BGA board. Perhaps Gelid GC Extreme may be a better choice.

 

IC Diamond is a better choice, its thicker and lasts longer in my experience..

that's what she said

 

Had good results from ICD, that said MX-2/MX-4 have worked well for me too, any reputable paste will do unless you're trying to go for that extra degree lower.

 

MX-4 lasts for a day or 2 and then pumps out.. Hence ICD is my hero, it lasts for 6 months at least..

I have used ICD for most my personal stuff along with some AS5, both seem to work very well

 

AS-5 is generally not recommended anymore, it's obsolete... I don't think it will be able to withstand the heat generated especially by desktop CPUs anymore..

 

Never had real issues with AS-5 but ICD is my go to.

 

Well, I actually ended up putting Gelid GC Extreme on , all is well

It will be fine.. Generally works for everyone.. I had a horrible repaste using ICD and only paste I have left is Gelid so probably will have to get more ICD or use Gelid!
