GPU fans don't work below 80%!

For a bit less than a year I had this problem, but at first it was only when I played demanding games. Then it went to mediocre games and now if I am just browsing the internet.

The fans don't work and when the graphics card heats up to 80° they work like crazy. Before that they had a set minimum and the GPU never over heated. However for the life of me I can't figure out when did they started to work differently.

At first I thought the GPU was dirty, but after a thorough clean up and observation it is definitely something to do with software. I deleted MSI Afterburner, "reset-ed" Bios to default and re-installed my GPU drivers. But it is still the same. I'd rather not have to download some third party software to set a manual speed, I simply want my GPU do to it alone as it did when I bought the damn thing, that means it worked on a small speed (I mean the fans) and if need be it increased the RPM, but that was never necessary.

3072MB ATI AMD Radeon R9 200 Series (Sapphire/PCPartner)
Windows 8.1 64 bit

AMD Global drive shows that my fan is working bellow 80% and that it gradually it increases as the temp does, but I am looking at the fans and they are simply not spinning, so I am definitely convinced no software is gonna make it work below 80%.

 

UPDATE: The only time I could manually change fan speed below 80% is after installing the drivers but before REBOOTING.

You may have changed something with Afterburner or whatever other OC utility(utilities?) you've installed, such as reflashing the card's BIOS, which would require more extensive troubleshooting to fix (this seems less likely - if you flashed BIOSes on the card though, this may be your problem). Alternately, the fan may be on its last legs and can't start at lower voltage like it should (and used to; this seems more likely); if you spin it up to 100% and then dial it back down to something lower (say like 40%) will it keep spinning? Or does it just freeze?
