AMD cpu stuck to stock heatsink

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

haf 912+
phenom 2 1075T

4gb ram
amd stock cooler

Help!

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!
