How to remove laptop CPU heatsink? + more questions

Go to solution Solved by Jurrunio,

If the heatsink wont come off, they are usually more screws in places you don't notice. For example my laptop, I need to remove two plastic vents that are there to look good and protect the aluminium fins first, then the frame with the fan held on by a dozen screws (the fan cable if I'm bothered to) which also covers the VRM, finally the heatsink held on by screws around the CPU and GPU (8 in total).

 

I'd try it anyways. Most paste will be beyond dry after a decade but can't say for all of them.

 

Depends on how dirty is the heatsink. If there's tar (cuz someone smoke), you'll have to soak it in soap or it will never be clean. Otherwise a small brush that doesn't lose its hair easily will do

The so many times I have opened up a laptop, I have always been curious to see the naked CPU die. But even when I unscrew all the screws of the heatsink, the heatsink is stuck to the die with a huge pressure. Am I supposed to do something else or just use a screwdriver (or more) and apply pressure upwards to remove the heatsink? Will it stick back into place easily after applying decent force and screwing in?

 

Also, do I consider replacing the thermal paste to a machine that is 10 years old? Do I really need to do this, or I won't see much improvement?

 

One more thing, my newer laptop used to reach the TjMax limit no matter what at full utilization in PL2(turbo) power limit. I had the exhaust heatsink cleaned, and now with the fan repaired (it no worky), it never goes above 85C in turbo. So, I am thinking to clean the exhaust heatsink of my older laptop as well, but I don't have compressed gas, I will try to clean as much as possible with a brush, but is sUbMeRgInG iT iNtO wAtEr a good idea? Also, I want to clean the motherboard as well, but I don't have isopropyl alcohol. Now I am not that crazy to s u b m e r g e that, so I guess a brush and cloth should do. Or I will try to get isopropyl alcohol.

 

Is it totally fine removing the CMOS battery? Like absolutely fine?

Microsoft owns my soul.

 

Also, Dell is evil, but HP kinda nice.

Dusting is good (Avoid the fans if you can).

Submerging in water is not good 😀.

You could rather change the cmos battery.

I wouldn't change the thermal paste but you can do it.

Chances are the heatsink sticks due to the thermal paste. It might rotate freely while sticking.

And it will stick again after changing the thermal paste.

I'm willing to swim against the current.

@Jurrunio Wait, wth? A 10nm 8th gen i3 exists? 10 NM?? I thought Intel got 10nm working only on late laptop 10th gen CPUs.

Call it a prototype that's good enough to not be scrapped. It's still released way later than many other 8th gen mobile CPUs
