It worked. Set fan management to manual then nvapoke e118 80000002 and you'll
get quietness.

I kind of have the same problem with the other nvc1 I have access to at work.
I'll be digging into this to fix this problem for good. Good that I got access
to this board, your bug would have been a mystery otherwise...

Thanks!
