Electric Cooling Fan Comparison Chart
 
I started making a comparison list for electric fans since I was interested to see what was out there.

I hope this helps some people. I know it helped me so far.

I already have a fan on my car but it pulls 14+ amps while running and 15+ when starting but it does blow a crap load of air and cools the motor down in a few seconds. I don't know the CFM rating but regardless its pulls way to many amps for me. I like 11 and under.

If you have more brands or fans that can be listed please post the information.

Here is the link to the list.

So which would you recomend for the cost versus function?

Aaron Cake 12-21-06 09:20 AM

There is a mistake on the page:
Amps / Volts = Watts should be A * V =W

It's also hard to get a good estimate on startup current unless you have the appropriate equipment. Most digital meters are too slow to respond to the startup peak drawn by the motor. To log this, you need a high quality graphing meter or a scope. Keep in mind that most of these fans will pull up to 60 or 70A for a second or two during startup which is well outside of the range of most cheap meters. Those meters may just show the maximum current, register an overload condition, or pop the fuse.

Other than that, how do you think the chart looks? If you/people think it's pretty valid I think I'll bookmark/subscribe this thread. If not... oh well.

taurus fan FTW! cheap and very effective

That is the biggest issue when finding the right fan. I Will have to see what the limit is on my meter or buy a cheap analog one that measure up to 100amp possibly. Manufactures only list the running amps and most of the time that is way off to.

My ebay fan was listed as a 7amp fan. I know its ebay so most of the time everyting is a lie and it was cause mine runs much higher then that. Although its been running for years without issues so I can't complain to much.

They are also old. So there years of service are numbered. Also, tell me what the startup and running amps are.

I had to make another SN because my other one wont except any of my passwords. I will have to look into that.

RotaMan99 12-21-06 10:50 AM

I also made a colume for the flow direction. As I was filling that column in I thought that it wasn't very important since all the fans I would have listed would be able to pull. So im thinking of getting rid of that column, think I should? Is there other information I should put in the chart?

our cars are even older...whats your point?

It's like 20-25 amps while running. When it starts it's about 40. This is more than almost all thoes fans and they cost like $30. you should put a price column on your chart. They fit the stock radiator perfectly and have a shrowd...cant beat that

RotaMan99 12-21-06 12:01 PM

What is YOUR point? You trying to compair the durability of a gasoline motor or a steel body to the durabuility of an electronic device that has a much shorter life span?

MY POINT IS, that electronic fans pulled from a junk yard may not last for many more years.

You have much to learn. The more amps is not always better, especially with our charging system. You want to look for the most CFM and the lowest AMP for the less strain on the electrical system. I saw one post on here about a guy that had a fan and he was all happy because it pulled 60amps!

You want to try and find a fan that runs at less then 12amp so it doesn't strain the electrical system. Otherwise, stick with the stock clutch fan cause you will loose more HP running a higher amp fan then the clutch fan.

I was thinking about putting a price column but it would only be an estimate since everyone sells them for diff prices, plus the price may fall after a while and im not going to keep up with that.

They're also from a Ford. Which, if you want my opinion, hasn't made a decent product in 15 years. :squint:

I havn't really looked at the cost yet, but the Sheraco fans are pretty cheap and have a high CFM rate and low AMP rating.

Vintage Air has some nice fans, you may want to add them to the list. Their Monster fan pulls 3700+CFM.

Only problem with Vintage Air is you PAY for what you get (which is a damn good fan!)

your car doesnt have any electronics? its not just a metal frame and a motor. if you search you will find there are many people using these fans and they are better than most aftermarket units. your right about the most current isnt always better, i dont know how many cfm they flow being an oem unit. sure they may not last for many more years, but you can say this about pretty much anything. if it fails, get another...they are simple to find, install and again they fit perfectly with the stock radiator.

RotaMan99 12-21-06 01:41 PM

I was more refering to a E-fan. I should have been more clear. My ebay fan has lasted me for about 3 years now and is still going strong. I don't know when it will quit but in my way of thinking, it should last longer then a junk yard fan. Im not trying to bash the taurus fan because like you said, a lot of people use them without troubles, I just don't want to have that thought in the back of my head that is saying, its old, used and it may fail anytime.

My main concern about OEM fans is they usually pull more amps then I like. Which is why I don't like them, but they are also built better so they last a long time, but the ones that you usually get from the junk yard are already 13+ years old. How much longer do they have to live?

I don't feel like installing many different fans if they fail which is why I like new stuff which should last a long time.

I give props to people using the taurus fan since they know that a shroud is very important. Some people will just hang the fan on the radiator not knowing a shroud is important.

I remember looking at those. Their 18" fan pulls some serious air, but is also huge. Will that fit on our radiators?" I suppose you could make it fit. The motor looks big too. I wonder how much power that sucks up. I will add that once I get more info on it.

Thanks for the link :)

RotaMan99 12-21-06 01:48 PM

I just noticed their braket is adjustable. Very neat.

They also have a shroud for a 18" fan that just may fit on our radiators. Look at page 69 at shroud 37202-VUF. 17.5" x 22" Be slightly big but could trim it to fit.

djmtsu 12-21-06 02:17 PM

The whole argument that the Taurus fans is old pointless since the motor can be replace with a NEW one for under $40. fuck

RotaMan99 12-21-06 04:54 PM

Your missing the major point.

Not going any further.

JCurry 12-21-06 05:08 PM

How are you guys hooking up these taurus fans? I mean what relays and such? And what year taurus are yall pulling them from?

Thanx

the search feature is your friend

JCurry 12-21-06 07:41 PM

Actually the search feature was not working or somethin when I wrote that, and dont get onto me about the searching stuff, im not a noob, I search more on this forum than I drive my car....lol....
