I've blown it out with the canned air but I haven't taken it apart yet to do a complete cleaning. As for the BIOS, I haven't checked to see if it does. I'm not that computer savvy anymore. It passed me by and left me far behind haha.
Mooshy, I just looked it up and it's supposed to have an option in the BIOS to turn off the smartfan and also change the voltage. I may try this to see if it makes a difference. Right now I'm using a cooling dock to keep it cool enough that it will stay running.
Haha no worries. Okay! If you feel comfortable try to see any settings in the BIOS that may help, or reset to defaults in case something wrong got changed. Otherwise like @jsmithepa said, call in some help and see if they have anything for you.
