Electric Fan woes

[Anonymous]

hey guys i was wondering what fan and CFM flow rate/mounting diameter/mounting width/etc. I bought a 2300cfm flow 16 inch fan with a 3.24 inch depth and i had to stagger it on the radiator to prevent it from grinding against the front of the motor. Needless to say, in a hard acceleration the motor torqued a bit and slammed the fan into the radiator which subsequently self-destructed the fan. Anyway, i re-installed the motor-driven fan only to find it makes the car run cooler?! :roll: Why is this? and what fan can i get the will actually fit?
thanks much guys

1) Im amazed you got the electric fan between the motor and the radiator.

2) Why did your motor move enough to smash the fan into the radiator?

3) Are you sure you had the fan installed properly? Some are pusher applications, meaning they go in front of the radiator.

How was the fan operated?

Sounds like you either had too small a fan for your application or that it wasnt set to come on when it was needed.

it was a puller, i cant mount one in front because i have a tranny oil cooler there. It was on a manual switch so it was on all of the time.

Sounds like you have needed a larger diamater fan.

Give me a call next week and I will put you in touch with our sales guy and have him set you up proper. We might even see about moving the tranny cooler to a differnt place etc.........

I am also surprised you sqeezed a fan in there. I guess you are still using a 2 row radiator. Anyways what fan did you buy? Just because they say 2300 cfm does not mean they actually pull that. They might be rated at 14 volts.

Do not take offence to this Philip. But, the only fans that I have seen work well on hi HP V8's are the Spal fans. If people can cool down those V8 monster's than the Spal fan should also work well for us.

If your engine did move that much to crush the fan you might check your motor mounts.

I have a 14" mounted as a pusher that works well with the aluminum radiator. But if I had room, I'd be running an engine driven fan with a clutch.

Sometimes when you add an electric, it actually blocks airflow thru the radiator. Another thing is that even a huge electric fan can't move as much air as an engine driven fan. An engine fan may use a lot of power, but they do move a lot of air.

It's a compromise.
