Hello.

About a month I use smcfan control, only for monitoring of speed of fans, the other day there was a problem.

Speed of the right fan shows about 2000 turns, the left fan consults, works for 6200 turns at loading.

In what there could be a problem?

I did SMC several times.

Prompt how to solve a problem

I will be very grateful

Try taking the bottom off and blow the fans out with compressed air.
