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 !!!!
