Is it bad for my iMac

[Beluga1000]

I'm wondering is if its doing any damage to my iMac if I download a fan control app and give permission to it. Thanks,

Depends what speeds you apply under what loads, short answer is yes it could be damaging if you're not careful.

What would you like to do with the fan control program? It seems you're running an Apple Silicon M1 iMac?

Yes

I bought a cheap iMac 27 with a bad sensor and I have to use Macs Fan Control or it sounds like an airplane. The alternative would be to replace the sensor. You just have to use a fan control program sensibly. As in don't turn it off if there may be a thermal problem.

Depends on what you do with it.

I use TG Pro on my M1-Pro during some 3D renders to run the fans at full speed because it keeps the CPU cool enough to avoid throttling.
