x51 cpu fan problem

[J_Johnson]

Recently, for some reason, my cpu fan runs on turbo speed.
this just recently started, the pc is stock out of the box, purchased in 2012.
sometimes it will run full speed for 10 seconds, calm down and 20 seconds later start it all over.
running LOTRO, is no longer fun, because the fan runs turbo speed constantly.

any help or ideas appreciated
running win 10 ( which updated on it's own, and I hate it)
thought about going back to stock win7 home, to see if that helps

thanks

Go through your drivers for EVERY part of your motherboard. It sounds like Windows has picked one for the motherboard which isn't sufficient!

well, found out the issue is 2 of the cpu fan hold-down tabs are broken, epoxied the tabs back on, new heat sink paste, installed the side cover and "pop" one of the other tabs popped loose (GRRRRRR) called dell - and of course, no parts available
ok so what are you folks replaceing crap cpu fans with??? my OE part # is F718g -- looking for new or upgrade, let me know folks -- I'm off to epoxy the 3rd broken tab

thanks
