Triathlete - good luck with the electric running cooler than stock - I tried two different shrouded, dual high flow flow fans to pull through the radiator and could not keep it below the stock running temps and consistently ran hotter. There was also a lot of noise and some vibration. A push fan on the outside might be more efficient but there is less room there. I also saw no increase in power with the fan removed. Please let us know how it works out for you though

Tone...I'm running stock fan with no intentions of changing. Why fix what works? I've never had overheat problems.
