rb26stagea Posted September 19, 2009 Share Posted September 19, 2009 Hi guys; I have recently fitted an aftermarket Davies Craig thermo fan to my car, and currently have it wired to the ignition, which is obviously not ideal. Does anyone know if the Power FC has an output that can run an electric thermo fan, or will I have to sort it out with a separate temp sensor and relay?

_Ryan_ Posted September 20, 2009 Share Posted September 20, 2009 Micah, have you checked the PFC FAQ? Link to comment https://www.sau.com.au/forums/topic/288615-power-fc-and-electric-thermo-fans/#findComment-4835798 Share on other sites More sharing options...

66yostagea Posted September 21, 2009 Share Posted September 21, 2009 I am interested in the idea of running thermo fans instead of the stock one.My plan is to fit a front facing plenum, fmic and thermo fans. Has anyone considered this mod or know someone who has done it to a street car? My son's S13 is set up like this and has not temp trouble even drifting on a stinky hot day. His fan unit is a double.

Daleo Posted September 21, 2009 Share Posted September 21, 2009 Some cars it works fine, others not so well. Just remember that a thermo will not supply anything like the volume of air that a viscous clutch fan can supply. From memory, at full whack, a clutch fan will pump over 3000cu/ft per min, a 16" thermo around 1500cu/ft. If your cooling system is marginal, it won't keep up. I've run them in the past and had no issues, always Davies Craig, never cheapies.

rb26stagea Posted September 21, 2009 Author Share Posted September 21, 2009 Yeah I hear you: the radiator has just been replaced with a huge PWR unit which even without a fan running, never saw over 85degrees whilst driving, and I now have a DC thermo fan on it. However, I am thinking now of adding an additional 8" fan or 2 on a separate circuit, purely for the sake of redundancy. I doubt the FC will be capable of doing what I want it to, and am now considering the Davies Craig fan switches, which will also allow the fans to run after the car is turned off...

KiwiRS4T Posted September 22, 2009 Share Posted September 22, 2009 Jaycar do a thermoswitch kit for about $40 (KC-5381 + box UB3) but I guess it would only be worth building if the alternatives were twice the price or more.

rb26stagea Posted September 23, 2009 Author Share Posted September 23, 2009 Pretty sure the DC ones are around $40 or so... I'll keep you guys posted on whatever solution I go with, and its effectiveness...
