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.
rubbing alcohol is ~70% pure isopropyl + 30% distilled water.
OR get unadulterated alcohol - an extremely difficult ask, unless you have friends in the chemical industry.
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.
