Cooling Fan Solution for 24V running A/C

[dude8383]

So I have finally found and installed my solution to cooling a 24V E30.

I chose this particular setup because I will be installing A/C and from what I've seen, few fan's are narrow enough to fit behind the radiator. I wanted to find something that would obviously fit and withstand the heat while sitting in traffic.

FF Dynamics makes some seriously high quality fans, I read about them on several Muscle car forums. I ended up purchasing their 12" fan.

This unit fits pretty darn close on the 318is radiator but leaves enough room to install the compressor. I got the chance to test it out today and it does the job quite well.

Now I wanted to be sure that I would have absolutely no problems overheating once I do install the compressor. I decided to change my aux fan as well. I purchased a 16" Spal fan.

Its a bit loud, I'd say just as loud as the stock aux fan, but again gets the job done.

So the way I have it setup is, the smaller 12" fan turns on when temp hits the 1/2 mark on temp guage. The high speed aux fan kicks on when temp reaches 3/4 mark. Once it does hit 3/4 the fan cools the car pretty quickly and shuts off after it comes back down to 1/2. The smaller 12" fan does not shut off at any point.

I'll try to get some pics of everything mounted so that you guys see the clearances. I will try to get the compressor mounted tomorrow.

Why is your regular fan set to come on so early? It should only need to run at low speeds or idle most of the time.

mines really close... spal ftw

What are you guys using for fan controllers? (are you using fan controllers?)

Mine runs off the stock wiring and a low temp oem radiator sensor.

werd.

my aux runs of the t-stat thats in the radiator and the 12" is running of another t-stat thats on the upper coolant hose.

i'll snap some pics in a few, need to cool of with some a/c in the house first. its HOT outside.

pardon the not so clean engine bay, i was bleeding the cooling system and that crap gets everywhere. the wiring is pretty f'in ugly too so that will be addressed over the weekend, i just wanted to get everything hooked up to make sure it works :)

looks purrty

Pardon my ignorance on this subject, but you had to delete your fan clutch for this mod to work correct?

well SOME people can fit the clutch fan, in my case there is no room for it!

[EightiesBaby]

so those people would be running THREE fans?

oh hell no man. you only have two choices for the radiator side, clutch fan or electric fan.
