Question Used Asus RTX 3070 works though fans don't spin?

[MutualBenefits]

Brought a used Asus Strix RTX 3070 from a person on craigslist, though it was too late that I found out he tinkered with it. Seems to work on my build though fans aren't spinning at all should I dump it, I got it for $300 because he said it couldn't game at 4K? Also, should I take a trade offer of RTX 3060 plus $100 for my old RTX 2080 to have it as a spare GPU.

Never buy an used GPU since it's been used to mine the ghost out of it.

Have you tried any utility software to spin the fans?

Also pretty much all GPU fans don't spin until they hit a temperature threshold.

I think it's the stutter bug from TPM, I tried to switch to ftpm to dtpm but my bios reset it and go back to ftpm.
