Greetings HW enthusiasts,
The motherboard of one of my system is RIP. When I took out the CPU
heatsink+fan, it came out with the CPU firmly stuck to the copper!.
I have tried to separate the CPU from the heat sink without much
success. I am afraid if I try any solution it might damage the CPU.
Any suggestion to resolve this 'sticky' issue would be much appreciated.

alcohol loosens anything. But detach the fan as alcohol could damage the
winding.

Will immersing the cpu in a plate of rubbing alcohol damage the cpu?

winding.
Thanks will ensure this does not happen.

No. BUT isopropyl alchol is usually adulterated with kerosene and naptha.
That leaves a white residue. This residue is an excellent insulator. If you
get it on the pins, there is some chance of the cpu becoming intermittent.
So ideally immerse only the heatsink and cpu without getting the pins into
alcohol.
OR get unadulterated alcohol - an extremely difficult ask, unless you have
friends in the chemical industry.

rubbing alcohol is ~70% pure isopropyl + 30% distilled water.

Not really true. 99.95% pure is available but expensive.
Slightly less pure but perfect for contacts is also available.
Another option would be to use acetone.

Not quite sure if available in small quantities. It is available in big
drums with excellent purity.

NEVER use acetone unless you are sure of the encapsulation material. It can
chew quite a number of epoxies and plastics. Although CPUs have a ceramic
substrate, the metal heatsink to ceramic bond is epoxy.
