Im a cheep skate and got twin fans and a adjustable thermostat off flebay (all new), bin on 2 years now and not a prob. Kenlowe to much money unless of corse you got plenty.
I did mine and it's defo not stock :lol
Cant stand the broody noise that viscous thing makes
I find most of the time they're not on at all. Also worth bunging in some "water wetter" stuff, it brings the running temp down a bit. Often used in race cars etc :thumbs
