ive tried speed fan, but i couldn't configure it. my mobo manufacturer only had one model(not my model) in the configuration website.I feel that if i could get my fan to run at 90-100% constantly i wouldnt have a problem. i assume that the temperature is causing the shut down. but once i put the laptop on an a/c vent, when i picked it up and tried to do something it shut off.. it wasn't even close to warm.. any input would be grateful
