WTB Stock main fan
 

Mine shit the bed at WSIR today. I need a fan to tide me over until I can get a low-pro setup together. Preferrably cheap, maybe free if you have it just laying around? I'll pay shipping obviously.

Will an NB fan work? I think I've got the stockers lying around off my '01 with 30k miles on them.

I can send the motor for the a/c fan :)

Is it the same motor as a 99'? Cause the motor on my 99's A/C fan has over 1/4" of slack in it along the axis of the motor's shaft, and it makes a bad "clicking" noise when I spin it, or an audible noise when running.

no idear. more than likely.

Flyin miata shows them being the same from 90-05. :)

Well If Sav doesn't want the motor you can has.

Sweet! :fingerscrossed&grin:

I require information on "low-pro" setup.

Buy some ebay fans and strap them to the rad. Cut the factory plugs off the old fans and attach em to the new ones.

To bad I never kept my fans, at least the motors. I tossed them in the trash after I got my slim fans.

I hate the ebay fans. There's a reason SPALs cost as much as they do.


The ebay 12" fan motor could not spin my stock 12" fan blades...dunno what that says, as the ebay fan blades are very very light comparatively, but it's obvious they didn't have tons of juice to be able to...

I know on some setups one ebay 12" 1600CFM was enough without shrouding, on other setups it wasn't. In fact on Newbsauce's radiator it wasn't; and his second 12" fan wired up in parallel, you could tell wasn't blowing as much air. Fortunately it was all he needed.

I'm still just running a stock fan with a slightly smaller core all-aluminum radiator compared (1.5" IIRC) to most here and have no issues dropping the coolant temps when the fans kick on, even without shrouding around the mouth.

Way off topic, but if anything, I'd like to find a higher power motor to swap into the mazda shroud/blade. Or perhaps a better blade to go onto the factor motor/shroud. I'm gonna have to do some research and see if some old car out there had badass fan motors that might can be adapted to work. The local yards have thousands of cars to sift through if I knew what to look for.

The reason is called name branding.

Personally, I got mine from siliconeintakes and wired in parallel its like a monsoon under my hood when they kick on. I have them unshrowded zip tied right to the radiator and temps drop as soon as they kick on.

I disagree. Spal puts a very powerful motor on their fans compared to the ebay special stuff. Spals pull more current, make more noise, and create a larger pressure differential when running. But theyr'e $$$. Nothing wrong with that, but I prefer to find a cheaper, easier, DIY solution if I can before I shell out the big bucks.

see what i say about the motor not being able to spin the stock fan blade...that says something. I can try the stock 10" fan tonight... I can even take a video.


just kidding, seem like I threw the ebay fan i had away...I am still however using an ebay fan motor and 10" blade without the stock A/C shroud for my A/C fan...no issues.

I just re-read that thread a few minutes ago and didn't see that. So basically you're saying the ebay fans have a weaker motor than the stock fans, but a better blade. Problem is the ebay fans have no shroud. In a perfect world, we'd put the ebay blade on the stock fan motor in the stock shroud and the blade would fit as well as the factory blade.

Been reading up on fans, I'm ready to come up with something.

try it: eBay Motors: Used 13" Cooling Fan Curved Blade Puller (item 300285215130 end time Jan-13-09 06:25:39 PST)

Like I said, the 10" blade fits perfectly within the OEM A/C shroud. But I'm still using the ebay motor...

I got another idea. I wanna get a set of motors from someone and take them apart.

There's a couple ways to make an electric motor put out more power. One is to double up the leads that go to the brushes. I've done this on a starter before on a high compression V8. Dunno how much of a difference it would make on a smaller scale fan motor though. But I just looked and the main fan's motor is just glued together, so it couldn't be too hard to get apart and have a look. Might be an easy way to mod the factory motor to get some more power out of it. Could possibly add another set of brushes, though that would probably make for a 'too powerful' motor that would be susceptable to overheating... But then again, that's how they make 2 speed fans....

Also the factory motor is a sealed unit. Could open it up a bit so it can cool better if it's indeed possible to put a second set of brushes.
