I used the cold spray method....but sprayed much longer than 10 seconds. In fact, I tried first with a short shot of spray...something like 10 sec., and had remarkably little success.

I then sprayed the block, on top and both exposed sides (the sides w/o the heatpipe entering/leaving the block) for maybe 30 sec., or even longer. I know the entire block ended up covered in frost as was the surrounding part of the motherboard.

I didn't use the motherboard proper to lever upon, though. Instead, I put a very small piece of wood along side the block and that's what I pried upward against. The entire NB section then just popped off lickety split. Only took a second or two of easy prying.....and I was quite worried about the IHS coming off as I had run the board on aircooling for well over a month prior to doing this.

Other things I'd consider to use as the "fulcrum" block.....a Molex fan connector, a thumb drive.....anything about a 1/4" tall or so to get the screwdriver off the motherboard and give you more leverage, so you can pop it off without having to twist the screwdriver, esp. against the motherboard itself. The slight increase in height will give you a lot of leverage, making it very easy to get the HS off......and it removes any chance of damaging any traces on the motherboard.

Here's what the bottom of the HS looked like after I got it off:




I just think you didn't freeze it nearly long enough......and I wouldn't worry about the frost that happens on the board.....your board will stand cold much easier than heat....just make sure you let the frost you create dissipate before you hook it back up to electricity. There are even companies that'll cryogenically freeze your electronics....supposed to align the molecular structure in all the metal to give better performance. Heard they do a lot of car parts for racing, too. (Pistons, rings, valves, metal brake rotors, etc. All for enhanced performance.)
