HELP: CPU Block Corrosion

[PapaSmurf6768]

Hi guys,

After taking my rig apart a little while ago for a motherboard RMA, I left my XSPC Raystorm just kind of sitting around with the thermal paste still on. I finally got around to cleaning it today, but some of the spots aren't coming off. Looks like it's corroded or something in some areas. Tried to get as best a picture I could of it, it's hard when it's so reflective:

Should I be concerned? Is there anything I can do? I'll contact XSPC and see what they say.

if all else fails you can always just lap it until the spots disapear.

Yeah if XSPC says "Suck it up" that's probably what I'll do. A quick Google is making me think lapping is a lot easier than I thought it was.

Is that a copper Block ?
If so you can use a copper cleaning product , you know the one you find in supermarkets for cleaning copper kitchen ustensiles like pans .

Thats what i did with my corroded gpu blocks and now they shine like the first day again !

Good plan boss, would be a hell of a lot easier than lapping. Will update you on what I decide to do!

a slow dip in distilled vinegar will shine it right up. no vinegar, then sitting
in a pool of ketsup or catsup. i'd bought some water blocks and they were
stained, so i poured a 3mm bath for the copper to sit in and monitored the
progress every 15-20min. after 45min bright and shiney. lapping can have
a tendency of de-crowning areas that may/may not be important. plus
can be a lil off and worsen the situation.
