reusing a cpu?

[brokeguy]

Is it possible to re-use a cpu from a pre built PC? I have a computer with a i7-12700F on a MSI pro b660m, 

 

 

the only issue is the motherboard has been fried, no clue if the cpu still works and have no way to check it

Sure, as long as you get it out of its socket and have a compatible socket in the new board, you can continue to use it

Almost always yes.

 

It is possible to lock some processors to specific motherboards - for example Lenovo did this with some Ryzen Pro processors, locking them to Lenovo motherboards.

So you do have to pay a small amount of attention if you plan to buy something, check description and stuff like that.

As long as socket/chipset compatibility is maintained then sure. There's also the addition caveat of the board needing a BIOS that supports you chip, but given that 12th gen was the first LGA1700 generation that shouldn't be an issue.

 

The only possible risk is that your previous board took the CPU along with it when it died. I'm not saying that's necessarily true (or even likely for that matter, it depends on how your board failed) but it is something to keep in mind.
