GPU fan will not go below 4000rpm. MSI Afterburner hasn't helped.

My GPU is a Gigabyte windforce gtx 770 and has been making an unbearable amount of noise. At first I thought it was just dirty, so I tried cleaning it out, but that didn't work.

After checking the fan speed I found it was at ~4200rpm. I tried using Afterburning to set a fan curve, but it just ignores it.

No matter what I do it will not get slower and quiet down.

The fan is that loud from the moment my computer turns on.

It didn't for a short bit after I took it out to clean, but then it started up again.
