Just about to swap out the cpu in sig for a 3770k. Current chip has liquid ultra applied. Whats the best thing to use to remove the old paste?
 
Do you mean one of the liquid metal ones? Goes on with syringe and spreads out over the IHS?

If so, your options are limited. The liquid runs into the cracks in the surface in the same fashion of solder wetting copper. This is part of why it works so well as a tim. It also means the only convincing means of removing the stuff is lapping.

You can use normal paste on top of it without ill effect, but the IHS will still look stained. Or you can use more of the same liquid. If you're selling it, the buyer may be twichy about it having a really high end thermal interface material filling the voids within the surface, but if so the same buyer probably doesn't want it lapped either.

I remove standard paste with alcohol, but I'm pretty certain that won't touch the metallic stuff. I just leave it on the cpu.

Not really the answer you wanted
 
Kitchen towel and a bottle of cd cleaner with isopropyl alcohol are what ive got to hand. Ill be using ultra again on the new cpu, so not fussed about it leaving a little trace on the heatsink base. If anything, with it "tinted" like this it will probably be a bonus. Just applying ultra to the new chip as i type this, luckily i had just enough for this cpu.
 
All installed and up and running again on the new chip. The base of the heatsink stained a little bit, but got most of the residue off with a scouring pad. Still have to clean the old cpu though. Screenshot of idle temps on the 3770k below.



Pretty similair to the 3570k on most cores, though i think core 3 on it had a dodgy sensor as it often read as low as 12c.
 
whats it like for load? does core 3 give proper reading then?

some brasso would have cleaned the heatsink up
 
At load in ibt, the 3rd core on the 3570k did fall into line with the rest. Still have to run a quick blast on the new cpu to see what temps are like at 100% load. So far in games its maxed at 50c. Thought about using some brasso but couldnt find it. Just used the scouring pad that came with the clu paste and a few drops of the cd cleaner. Screenshot below of the new chip running p95 small fft.

Get overclocking mate. :D

Metal polish finished with alcohol will take Liquid Ultra/Pro off with a perfect finish, no need to scour it next time :)
 
Will do once i get a bit of time.

Wasnt that fussed about getting the cooler base perfectly clean tbh, the cpu itself has stained a bit. But it's only cosmetic and wont affect it's operation. Cooler is an alpenfohn k2 wazza, pretty similair in performance to a d14, though ive replaced the stock alpenfohn 1500/1100 rpm fans for x2 1900 rpm akasa piranhas.
