Im tring to replace my stock cooler with a gelid tranquillo v2. I have unclipped the hsf from the brackets, but the heatsink wont part from the mobo, as the termal paste is now like concrete. Pulling doesn't work, it wont twist what so ever. I have heard that alcohol on the contacts between the cpu and hsf may work, but also that heating with a hairdryer may work. I am not going to try stressing by Prime95, as I cannot be bothered to reconnect again
Specs:
haf 912+
phenom 2 1075T
GB GA 870A UD3
4gb ram
amd stock cooler
5850

unplug the fan, go into the bios and look at hardware monitor, wait for it to get to about 50C, and try again

Has this been tested???
The stock heatsink with the fan is pretty crap, without I think it will overheat very fast, and wouldn't a hair dryer do similar?
I just dont want to take any risks.

First, try twisting the heatsink back and forth if you haven't already.

If not, then yes. 90% or better isopropyl alchohol does work - soak the heatsink contact area in it for at least 5 minutes, then get some dental floss and start at a corner of the processor/heatsink contact area and gently floss it. As you go along the processor go back and forth while applying force in the direction away from the corner where you started

good luck!

just drip the alcohol on the contact area.

Used a hairdryer, twisted it with my strong hand and it came off like a dream.
Turned out I was using my left hand. Thanks for the help.

congrats!

If you ever run into a similar situation, you can use a medicine dropper to get the alcohol to the contact area.
