Rad fan on the outside? Do's/don'ts,tips/tricks

[billythakidd]

So my buddy is talking about putting his radiator fans on the outside of the radiator..

Kinda makes sense you push air into rad when you ride anyways

I got a rad cage and I could easily weld mount tabs to it if this works for a 2nd fan

Sorry if this is a repost search button dosnt work on my phone
Anyone that has done this a little input would really help out

Thanks I heart you guys !!!!

pulling air through and pushing air in seems to do the same, if anything seems like the fan on the outside would block a lil bit of air. but the fan on the outside would look goofy imo plus i dont think it would fit with fenders or fairings

I was thinking like top middle of the rad for mounts for 1 fan would clear all an hardly be seen and really wouldnt block air, basically just the fan motor would block pushed air

Then even when your up air still push's in

Edit: I can't spell

keyword... cause just as much as it kinda makes sense, it kinda doesn't all at the same time.

yup. theres not a lot of space between the tire and the radiator as it is, and you wanna close that gap with a fan motor? illogical!

Push/pull systems are often ran on cars, where the radiator is boxed in. With a full upper and lower it might be beneficial, but on a bike with an radiator in open air there would be no cyclone effect.

Just run the pushing fan on the outside and staggered of the puller. At least the fan motor will be cooler, lol.

I would think less air will go through the front with the fans on the front , like Austin said

how do you keep the tire/fender from hitting the fans?? sounds like a for sure clearance problem
