Diy cooling fans
has anyone built their own cooking fan system? Ive been kicking the idea around for a while now and think Im gonna squeeze the trigger. I basically want to just build a set to test, then after I get some miles on them and work any bugs out, Ill build a better set and Powdercoat them. If anyone has done this, what fans did you use? How well did they stand up to water?
Im looking at 4 inch fans that only cost about 60 bucks. They will be going inside a steel housing that I will tig weld, then powdercoat In the barn. Originally I was thinking of going with a cylinder shaped housing, but I might try diamond shaped depending on the size and appearance once I get the shell fabricated and mounted. Also looking to make them quick connect so cleaning my engine fins is easier.
Any advice is welcome. Hopefully Ill have a good final product to post back with.

There used to be a guy around here that R&Dd a bunch of fans.....I believe he ended up using some computer fans.......nice set up with a heat actuated switch. Worked GREAT......started to sell them and got burned down by a large corporate thing............now he's gone and the big corporate thing is selling his design............but there are still some of his artwork in use out there........you can them on my sig pic..........
Good luck.......watch yer a$$!

Wow I wouldnt expect computer fans to hold up very well to moisture but whatever works. Im by no means looking to make a business out of this, just want to build my own system for my bike and the ols.

The above linked fans are supposedly what Wards used. IP55 and about 60 cfm.
Personally, that seems a little inadequate to me. If I was doing thisyself, I'd dig around a bit more for something more robust. IP65 or better, all metal, maybe fluid bearings (would need to research fan bearings with regard to heat amd vibration) and at least 100 cfm. Maybe marine bilge fans or something from ebm pabst.

Well I will tell you that the 60 CFM it quite adequate........I can idle my bike till it gets to 275*-300* and turn on the fans and in a matter of minutes temp is down to 235* and stays there.
AND I've had these on for like 3-4 years now with NO problems.

I was actually planning on using 240 cfm fans. As far as triggering them goes, I just want a simple toggle switch as I will only need them when riding in the city on hot days. When its 80 or higher it only takes about 2-3 minutes to hit 300 which is where I shut it down. I dont know the amperage they draw but finding out is definitely on my to do list. Im not too worried about the stator because Im not gonna but fans that draw a lot of current. As Im sure you know they draw much higher current when first starting than they do while theyre running.
