Let us know how it works.
I can tell you that my fan being wired directly runs at the same speed as the factory installation judging by the sound. I'm not about to stick my finger in there and count the whacks.

based again on the limited run I did, I can't see a reason for the low speed other than noise.

It faked me out into thinking it was the regular speed, till I heard regular speed later that day.

If it ran for 2 days, and you didn't notice any issues, I would still try and return it.

If you smoke the replacement, then try feet's idea.

I guess the other question is, how long was the actual total run time. That is you had it hooked up 2 days, but did it run 1 hour or 8?

IMO not starting anything but on 01/14/10 3wbagell you started a post on overheating.A member offed to help you that didn't live far from you.You were concered about the cost of small items.Did you ever get that issue solved?Are you going to keep guessing or did you follow up with the free help?Like i said not trying to start anything but have you ever finished anything you started with this car?

i think the total run time would be somewhere between 3 and 4 hours.
it did exactly what the directions said it would do, it burned the IC card.

Just a heads up for anyone wanting a real nice fan controller... I've been building my Torana for a while, and used a Spal controller to run the fans on it Spal Fan Controller and just got it all dialed in today. Works awesome

Has low and high temp limits for the fans along with an a/c input as well (which I used) so it kicks them up automatically when needed.

It can also use a factory sending unit if you want too, or add thier own. I am running mine off the stock sending unit..

I'm still testing the older fan.I have it hooked up to a battery and the battery to a charger set on 20 amps to keep battery charged so far the fan has been running nonstop for 5 hours no problems yetNo smoke no nothing just runnin.Here are some pictures.

another pic

did you bypass the controler box?

Wonder it it is the starts and stops,not continuous running?

Didn't bypass running it straight.I just cranked the amps on the charger up to 40amps.Fan picked up a lot of speed.Will let that run till it gets dark about 3 hours from now.Inthe morning will let it run for five hours and see if it lasts .

Last one till tuseday

When i increased the amps to 40 the fan cut off after running for 1/2 hour.In the morning i will cut the wires bypass the box and try that.

Not sure if that would be a good idea. I think the fan uses a capacitor to get it started.

I didn't have any luck bypassing the box and jumping power to the motor. It would spin once or twice then shudder back and forth while trying to cook the wires. I never did cut the wires to eliminate the box on the old style motor I played with. Maybe eliminating feedback from the control box will help.

When the fan died, would it start again?
How long did it run on 20 amps?

I see that your fan is an aftermarket unit also. I wonder if it's made by the same people as the one Performance Only used? Is there a manufacturer's name on the motor or controller?

Fan just shudder and shaked wouldn't run.I had cut wires to controller and bypassed

It looks like the older style aftermarket fans won't handle the direct 12v signal. Apparently, a 40 amp feed is a little too much for it.
I haven't tried the old style factory fans. I could set one up to run but my battery charger will only hold 20 amps. It would eventually discharge the battery.

The new style fans don't have any issues.

Is this the right fan to get?

Is it the older or newer one and any adv/disadv to either?

This one cheaper; not the right one?

The newer fan is the one to get. It requires the controller found in the new products section. Running a direct 12 volt feed to it will kill the fan.

I have not worked with the older fan. They had stand alone controllers and are wired differently than the fan I used. If you take that path, you're on your own.

Great info, glad you posted it the flexalite fan on my 71 won't keep it cool.
I was wondering, do you think it would move enough air to cool down an 01 cummins? The elec fans for it are in the $550 range and I don't trust flexalite.

It should handle that with no problems. These things move an insane amount of air.

I don't know the dimensions of your radiator so I can't say how it will fit.
The fans with the metal heat sink MUST use hooziewhatsit's fan controller.
Other fan controllers on the market will NOT work with these fans.
