Title: electric radiator fan options
Post by: nomad on June 27, 2008, 12:10:45 AM
I came across these electric fans online. Anyone think it'll last a few years?

14" fan, flows 1800cfm but is no name and seems pretty basic. $30

Better to go get a junkyard 200,000 mile electric fan etc? (worried about it crapping out)

I don't know which would crap out first, a 200,000 mile OEM fan or a $30 aftermarket fan, would be a pretty fair competition, haha.

I'm curious how that fan manages to make that much airflow though.  Spal, a maker of high quality electric fans, has a 14" curved blade fan and it can only do 1720 cfm at 16.3 amps. info here (http://www.spalusa.com/fans/automated/tech_sheets/2042-2056.pdf)

The fan you posted just has simple flat blades, isn't as deep and draws only 7 amps while creating 1800cfm?  Some wizardry is at play here if that cheap fan can be so much better than an expensive fan.

yeah, that's what I was thinking. There's someone on the other forums selling a use one... for more than the website sells them new. ha ha

For something as crucial as the cooling system, I don't think I would trust a $30 fan, that doesn't appear to very efficient, to keep my coolant temps down in the hot summer. A nice "high performance" spal fan can be had for less than $100 new, is $70 really that much money when it comes to critical components to your engine (not blowing up in your face, leaving hot boiling liquid that smells like melted mike & ikes, when you open the hood after you over heated your car because your $30 piece of crap fan decided its super cool reverse switch technology wasn't uber cool anymore and refuses to go on as a total square), I don't think so, haha.

I would still trust any used OEM JY fan over aftermarket. The car makes has a huge warranty liability if the car overhears. The aftermarket really has none. They are all made in china.

went to the JY today and didn't see JACK! I saw the perfect volvo candidate but it had the fan pulled already. I did get a volvo front lip though, so that was cool.

The fans used in Lincoln Mk VIIIs and Ford Tauruses (same motor, different shroud and blades) are impressive, but power hogs.

Fans aren't THAT crucial...:rolleyes:

I mean, they only get used when you are driving below 20 mph in hot weather.  I drove my 2001 E46 330i around for a few weeks(an experiment only) in the winter (50F-60F) without any fan and it didn't overheat.  The needle stayed perfectly vertical once the car was warmed up.  I was even able to drive in stop and go traffic without the temp gauge moving.

A properly functioning and sized radiator and a working thermostat are a much higher priority than a fan in my opinion.

Sorry, I live out here in the Inland Empire. ;) Temps are once again kissing 98-100+ and we're just getting into it. After replacing one cyl head... ALL cooling components are important. Problem is that i can't afford a fancy SPAL. :(

so what's the concensus? Volvo 850 FTW?
Its 50% off this weekend at the 'yard so I need to find something.

Try volvo 940 or 960 first. Same fan but the shroud is easier to adapt. 850 fan and shroud is second choice.

I've heard that the 318ti electric fan is a good option but i haven't looked into myself yet.

I wish the 'yard had one.
This weekend I hope to see some of those as well. I'd love to get a LSD. Preferably 4.45 or whatever it is

I have a Mk VIII fan in my Corvette - when I test-ran it with a set of jumper cables off of my battery, it sucked up small gravel from my driveway and threw it at me.  The sucker moves serious air.

MK VIII = Lincoln?

Can these be used with our stock/M44 auxiliary fan switches?
Title: electric radiator fan options
Post by: tjts1 on July 02, 2008, 06:44:59 PM
Yup. I connected my fan directly to the aux fan circuit (sent the aux fan to the circular file) and replace my switch with the colder M44 switch. Its a 2 speed fan so all you have to do is identify the low and high speed on the fan and car to run it through the existing relays.

Yeah.  I'd almost be afraid that it would inhale a little 318i radiator.  :p

Saw a mark viii today but passed on the fan

Got one from a 950 volvo, now to hook it up and take out that stupid stock fan!
