HWinfo

Hello. So i have new laptop by the name of Dell Latitude 3350. My fans seem to run constatly at 7000+ RPM even though my cpu is on like 10% use. HWinfo or speedfan doesnt work. I've set the computer to power saving mode and quiet mode through Dell Command Power Manager, but it still doesnt work...

I am having a problem for 5 weeks that I can't solve and it's driving me crazy. By the end of the post, you’ll see why I need help from you guys. [EDIT: My warranty expires shortly. There are so many unexplained things, asked as 3 Qs at the end, that I have to assume this problem may recur...
