2,000 + Grit sandpapers

[EarlZ]

---

For the obvious reasons for heatsink ang CPU/GPU lapping, Im wondering where can i buy a 2,000+ grit sandpaper. the highest i can find is 1,200 grit.

murag wala man sad gyud ko kakita ug 2000grit nga sandpaper bai... nagpalit pud ko... 400, 600, 800, ug 1200...

EarlZ, you DO NOT NEED 2000 grit!
The processor does not need to be shiny! You need to make the surface FLAT, of booth surfaces, the processor and the cooler.
Even 800 grit is enough.
After lapping, you use little thermal paste (size of a rice corn), and spread it with a credit card or something similar. This fills the gaps. Thats it.

i agree...been lapping for some time now & even noticed when i reached 1500 grit, i would go back to 800 to get it more polished.

Flatness is very different from polishing

so why need a 2000 grit if the aim is just to get it flat?

LMAO, Isnt the whole idea if lapping the CPU/GPU and heatsink base to get a close to perfect flat surface even for a mere 3-4c drop in temps ?

I would advise that you read more on the difference between flatness and polishing when it comes to lapping. ( no offense ment )
