Why CPU fan runs at full speed?

Hi Guys!

I have a problem with my macbook.

Few months ago I replaced my spilled keyboard and after that iSight camera doesn't works anymore.

Today I decided do fix it. After disassembly I noticed that there is some deformed pins in camera/wifi connector. I fixed that and after booting my mac I was surprised - the camera works. I make a FaceTime call and camera really works great, without any problems. But later i noticed that CPU fan spins at max (sounds noisy) and CPU runs at only 796 MHz all the time. I was trying to boot with unplugged camera connector but it doesn't helps.

Please tell, what can I do with it.

Thanks.

I've done all resets (SMC, PRAM) few times but doesn't succeed. Then I decided just to completeley reassemble my MBP to make sure that everything is clean and well connected. And OMG, it work fine so far. Thanks for your replies guys.

You should apply new thermal paste to the heat sink and stop using the laptop until you do.

Sounds Like battery trouble. Is the battery ok? Did you try a SMC reset?

My battery is really old and has only about 50% of health. But it's not the main problem. Thanks.
