PWM cooling fan(s) control using ECM - Page 49 - Lateral-g Forums

Here is a dumb thing, it is seemingly impossible to purchase a Spal brushless fan by itself anywhere on the internet. It seems they used to be everywhere and they have all ghosted.

Anyone have a source?

I'm sure DeWitts will sell me one, I was just surprised when I couldn't find it at Summit, Lane, or anywhere else where they had been listed before.

Semi related, I have the GM 600 watt fan in my hand. Part number 23376530 It is absolutely a Spal unit, their name is all over it. Not sure if that is common knowledge or not.

The fan blade measures 14 1/4"

The meat of the shroud is 23" wide and 13 1/2" tall. This would work really well on a 24 x 16 core.

Doesn't Holley sell Spal fans?

I just checked, and I see what you're saying.

It's hard enough to find info on the brushless fan lineup, let alone find somewhere to buy it!

Wizard Cooling has a bunch for their radiator setups, but don't list them individually. Found one 16" puller and one 12" pusher on Kartek.com

Story is that Spal doesn't have any faith in the general publics ability to properly mount these fans. I didn't get a technical explanation.

I got the one I needed ordered.

Donny,

Do you know the OEM application for that fan?

The brushless fans are easy to spot because they have the heatsink on the motors and the big, round Yazaki connector with two big wires and a small wire for the PWM signal.

Found it. Looks like C7 Corvette.

C&R makes C7 Radiators and they will sell the little aluminum tabs that can be easily welded to any aluminum radiator. That is what I did with the C6 fan on my Cougar.

So Andrew,

The brushless Spal fans have the PWM built in to the motor housing, eliminating the need for the C6 controller?

I'm just trying to get an idea of wiring, and would love to eliminate the C6 controller of I can.

Thanks!

Yes, the C7 fan and the Spal brushless have the controller built in. You still need to send it a signal though and I do not know if they require the same signal.

They both appear to take the same Yazaki connector and they are available as a kit on ebay pretty reasonably.

....

That is my understanding. I do not have first hand experience with them, but this thread has all the relevant information.

Although, if you already have a C6 controller and a good fan, I see no reason to change.
