well i am in windows and so far so good but i only see 4 of the 5 GPU's for some reason... will have to figure out why and address it. though i have the 4 GPU's running and folding stable.
as for the fan controller it was a Silverstone CPF04 1-to-8 PWM Fan Hub. but i can buy a replacement capacitor for it and it'll work just fine again. i had the power to it reversed when i changed its sata connector.
EDIT: just to figure out the issue with the missing GPU i will have to completely take apart my system again... so screw it im running 4 GPUs with 5 slotted. just disable the slot with the mobo switch and unplugged it.
