Fan Speed suddenly spikes and drops. Radeon HD6770.

I have a MSI Radeon HD6770. I had flashed it to 5770 for it to work on Mac OS X 10.8. And it worked fine. But i removed mac so i reflashed the card with a rom from techpowerup. Also, i updated the drivers to 12.11 beta 8.

Now the problem is that, the fan speed suddenly spikes to a 100% and then falls back and this happens multiple times in a minute and i can't figure out what exactly the problem is. I noticed this problem only after re-flashing and updating drivers, so i'm unsure as to what must have caused the problem or if it is something else. I have added a screenshot from both, GPU-Z and Afterburner so you can get a better picture. Hope to get it resolved.
