I have a noisy fan on a relatively new Aspire with a 8 Gig flash drive After a minute or so the fan begins to rumble as it kicks in The laptop is running Xbuntu linux I have read a number of possible fixes 1) the software patch. My concern is if I slow down the fan of overheating 2) thermal paste. One person said by replacing the thermal paste this solved their problem 3) update the bios . The current bios is .3109 any help and recommendations would be much appreciated thank you
