This laptop seems familar

Is there much difference in the temperature compared to stock paste / self applied liquid metal ?
This particular LM need some time to cure for best results.

initial temp difference after application is between 7 to 8 degrees

The stock thermal paste from lenovo is already very good (Shinetesu 7921)

replacing thermal compound is idiot proof. even without experience can do.
I think it depends on the manufacturer. I recall there were couple of instances where I open the laptop, and then I close it back because it was too troublesome to get to the heatsink.

Nail polish insulate (1st coat)



Nail polish insulate (2nd coat)



Silly question, will any nail polish do the job? I am not talking about the color of the nail polish, rather is there any specific brand that is tested, or just any cheapo nail polish will do the trick too?

Anyway, I read that when you apply liquid metal to bare copper (i.e. the heatpipe in this case), you will need to apply it a second time. Source below, mentioned at around 13 mins into the video.

The purpose is to insulate, using nail polish is just a matter of convenience.

Just make sure the nail polish is not electrically conductive some nail polish do contain some metallic looking dust, these are not recommended.

To apply a second time on the bare copper HS is subjective , depends on the type of LM used.

Need to insulate. So that the liquid metal won't touch the other components

thermal conductivity of liquid metal is much higher than thermal paste, even the best ones. it helps to transfer heat from cpu to heatsink as efficiently as possible, allowing the cpu to run cooler even with same heatsink.

however, liquid metal is not for everyone as it is also electrically conductive. if it flows out, it might short the motherboard without an insulative layer like the nail polish. it will sometimes leave permanent marks on the heatsink and cpu too.

I used Grizzly, a type of liquid metal, and it was pretty easy. Just keep it a drop or two so it doesn't leak out on the side.

Also clean the previous thermal paste w alcohol.

How tight should/do you screw on the heat sink after apply thermal paste? Too tight paste all squeeze out, not tight poor contact & conductivity.

Saw your post on reddit. Have you checked your temps recently to see if it degraded? The LM should form a layer of alloy with the copper and hence probably need to re-apply LM?

Word of caution, liquid metal can used on desktop CPU which have lid over it.
Notebook which chips are exposed, recommend using normal thermal paste.

I killed one notebook before when using wrong thermal paste which either is electrical conductive or consist of metal.

Noctua HT-N1 is the safest choice which I have been using to service both desktop and notebooks.
If you want to bring down notebook temp get a nb cooler as well.

I want to know if my 6 yr old lenovo laptop thermal pad can be replaced with new thermal paste. Its been running hot recently and i think its due to the heatsink and paste dried up or something.

SLS ppl can help to replace the thermal paste?


Go youtube, learn and DIY.

Didn't noticed any degradation in temps. Been using average 6hrs daily.

What was observed was the XiaoXin Pro is limited by the PD limit of 65Watts. which R20 tops 4300ish. @87deg with the LM application.
