So I have had my Toshiba A30 laptop for over a year and it has worked well. Lately the fan started to run at high speed all the time and performance was sluggish. I was thinking the heat sink on the CPU needs adjustment or that the fan sensor is flaky. So I did some googling ( GIYF Google is your friend) and came across an article on the same laptop with the same problems. I followed the instructions and found that my heat sink was all clogged like his.

I cleaned it out, and now my laptop is running cool and quiet.

Cheers…
