How to detach Lindbergh CPU from its cooler?

[bubbly]

When trying to replace the cpu fan the CPU itself came with it.
I tried to separate them but it looks like glued or maybe the thermal paste is too dried it just won’t let it go.
I tried several tinks like alcohol or using dental floss but nothing.
I was able to get a working cpu replacement but I would like to separate the original cpu from its cooler.
Any advice?

Do not try the hairdrier trick. I've done it like this guy usually works well.

oh, very interesting! I didn't think about that.
I'm afraid I already toasted the CPU with the non-recommended way of using the drier... but I'll make use of if on my other Lindbergh
Thank you!
