I think you'll have to open it up to peek inside to guess if the new HSF (heat sink fan) looks to fit.
Also, you would check out your PC's socket type and see if the Cooler Master (you didn't reveal which CM model) lists that socket type.
My fan is going bad (A7015-45RB-3AN-C1) and i want to replace it ,
but i want to replace the whole unit fan and cup. I would like to know
if anyone knows of a unit that would replace the one i have. My computer is a cyberpowerpc model Z1-7641.
Thank You for any information you can give me.
