Uhm yeah, I need to replace fan on CPU,since stock one can't keep up with my demands anymore, unfortunately ain't have isopropyl alcohol so is it possible to use acetone instead? are the any risks regarding this?
I wouldn't.
Acetone is a strong solvent. It is not like alcohol. It can soften or completely dissolve petro-chemical or polymer based materials. This is good for cleaning and degreasing metals, but NOT good for spills on other materials.
Any pharmacy should have isopropyl 70-90% rubbing alcohol. This is fine.
