My MacBook Pro (mid 2010) has cursor problems when the fan comes on.

Hi, I have been trying a variety of recommendations to see why my MacBook Pro seems to be having slowness issues. yes, I took it in to the Mac store and they found nothing. I have tried some other things that I think may have helped but now I see that specifically the cursor goes crazy when the fan kicks in and when the fan goes off it is okay again. I have run SMART Utility & I didn't see anything from that.

MacBook Pro (13-inch Mid 2010), OS X Mavericks (10.9.1)

The fans coming on and the cursor going crazy are a correlation, not a cause-and-effect.

The fans come on when measured temperatures inside your computer are getting too high. The fans come on to try to exhaust the excess heat. If the cursor goes crazy at the same time, this is likely to also be caused by the computer getting too hot, not by the fans.

This is one possible cause:

Runaway applications can shorten battery runtime, affect performance, and increase heat and fan activity
