I hope this is the right forum for this posting. I'm thinking of building my own watercooling block, using an old video heatsink as the base of the block.

The size seems perfect for my celery (566), and 72 watt peltier. The only thing holding me back is my fear of ruining the heatsink (not to mention the video card), if i use my trusty plier to remove it.

I think I read somewhere that putting it in the freezer for awhile, somehow lets you just pry or pop off the heatsink.

Thanks in advance and my apologies if this is the wrong forum.
this should be in the cooling forum, but thats alright. Yeah, the freezer trick works well because it makes the glue bonds much more brittle.
Dont forget to put it in a freezer bag of some sort 1st, ive done this a few times and works great. ive never really been told a proper length of time to put it in for, i think ive heard 45min, well mine was in there 1h and worked good.
Play a game of Q3A for a while pop out the card and wrap a flat head screw driver with a cloth or something thick enough and stick in between the HS(underneath HS) and card not damaging the lil parts and just twist slowly it should pop off. Use acetone to clean off.
