Fan won't stop running

crwdns2934249:0crwdne2934249:0:

I easily replaced my broken exhaust fan. (the old one had two small broken plastic pieces causing the fan to still work but it rattled).

The new fan now spins ALL the time, regardless of the laptop temperature. It starts spinning at 2000 rpm  as soon at it turns on. From a dead cold position. This causes a low annoying hum. I tried resetting both the SMC and PRAM but the problem persists.

Any ideas?

Thanks
