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?

Yes. At second floor. There are few shops doing this. Cost about $30.

This can easily be performed by yourself. You have already opened up the base, so its a matter of removing the 6 screws holding down the heatpipe to your CPU and GPU, and the cooler should be free to remove.

Then you should also try to clean the fans. They look dusty, and not unexpected after 6 years of usage.

Not as easy. Need rubbing alcohol to wipe the previous paste away. Then buy thermal paste and apply it.

It is not hard. But if you are not comfortable with it, better get someone else to do it for you. Considering it cost $30, that's not too bad.

I don't get it. How does wiping old thermal compound and repasting make it not as easy? You don't need alcohol to remove dried thermal compound.

It is down to your confidence level. I am just letting you know that it is a simple process, though you will need to spend money to buy thermal compound.

stock thermal paste tends to be low quality.

I used Thermal Grizzly for my XPS and it made a big diff. It never goes above 85 even when I OC the GPU.

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)

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. :s13:

Silly question, will any nail polish do the job? I am not talking about the color of the nail polish:s13:, 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.
