I've had a problem with my iMac fan kicking on because it is getting hot. I'm always running Safari when this happens. Once I switch to Firefox the heat dissipates and the fan stops running. This has been going on for quite some time now when using Safari. Why doesn't Apple fix this issue?
close safari, hold down the shift key and relaunch safari with it held down.
if that does not fix the issue the next step would be reset the SMC and PRAM
