Wet sanding would make things a bit quicker, but messier. Once you start getting down to copper the redish powder gets all over your hands and makes a mess.
So you're going to risk corrosion? Electronics are all made from metals. I've seen circuit boards with rust on them...

You're also going to likely have water molecules stuck in the pores of your heatsink which will turn to steam when it gets hot enough to boil and create air pockets in your thermal paste. Scratch that, water boils at 100 degrees celcius... oops. But the water will still cause corrosion.

Sure, you can reapply thermal paste. But what are you going to do if your heatsink is corroded to your cooler? Pry it apart and wet-sand it some more? It's not like you'll see it coming unless you make it a common practice to remove your cooler on a very regular basis.

But hey, go ahead and take a needless risk. You're already voiding your warranty. Wet-sanding may be safe but dry-sanding works just fine. It's not my dollar.

lol , anyway , what I use is cooler master's thermal fusion 400 .. It's got a low thermal conductivity , but small particles that work better than AS5 O.o

Very debatable... but thats not the point here.. so 600 grit max feels stupid for me .. I think 800 should do it for me .. mirror would be going too far..

*************

So water paper and a BIT of H2O with some sanding = win ??

Do that 2600K xD

Using a polishing agent is foolish ///

isnt the warranty already void if we overclock the processors anyway ?

Ok it does not ruin the CPU. Us engine builders lap the sealing surfaces where gaskets go to make the gaskets seal better, and its done the same way, 600 grit sandpaper and working up to like 1000 grit. Same with a cpu, cept it makes the CPU flat(like the mating surface of an engine) and it also makes the TIM spread better onto the CPU. Dont ever lap a CPU without a IHS. You are lapping the IHS on a cpu. It pretty much makes the temps better. Only downside that i can think of is voiding the CPU warranty.

I think that would depend on the cpu. For the 2600k I would have to say no, up to a limit. They specifically advertise "Unlocked and unleashed." But if you overclock past 3.4GHz then your warranty is void? I highly doubt it. They marketed the 2600k specifically to overclockers.

Also, some motherboards come with the turbo boost on by default, mine did. So that means my cpu was already being overlocked to 3.8GHz without me even doing a thing.

Now if you overclock to 6Ghz and end up burning out your cpu. I would say they will not honor the warranty. Yes, it will be completely obvious if you do that.

Agreed there isnt really much of a point to wet sanding, all wet sanding does is make it easier to deal with the dust created from sanding a substance, like metal or paint. Wet sanding dosnt make any smoother of a surface. Now if you take valve lapping compund, its different because its pretty much tiny pieces of aluminum oxide suspended in some type of light weight oil. So it wont corrode the CPU, but you have to use some kind of evapourative degreaser when your done to remove the tiny pieces of aluminum oxide and oil. The degreaser id recommend is brake cleaner, pretty much its a mix of isopropanol alcohol and hexane. Evapourates super fast, and leaves no residue behind.

Kay .. Not going with the cool compounds and all I think the metal dust coming off the CPU's IHS while lapping should suffice..

Have isopropyl alcohol lying , will use..

Screw the warranty!! We're here at OCN Don't care abt warranties much xD
Hmm... explain my copper on the Hyper 212+ I had corroding a bit in under a year ??
Reside off my hands ??

Technically, the flatter the surfaces, you are right, the less TIM you need. And no, do not use polishing agents. If the CPU and contact base were both 100% flat in a perfect world, you would not need any TIM.

Before i lap it... i will post load temps as well as idle temps before concluding i am 1337?
