Electric Fan Engine Cooling

I have a 69 Camaro with 383 stroker and with a Wizard Cool custom radiator with dual 12" SPal fans. I am running a sensor that turns them on at 180 degrees. I also have a manual switch.
Question: What are others doing here, are you running then constantly or same as I have described here.

Just want some thoughts on this.
Thanks

Re: Electric Fan Engine Cooling

My set-up with the SBC,3 row aluminum (stock style replacement) with twin 11"-12" ? (forget) that were on all the time with motor running. No issue.
Now with the LSx using the same cooling system and a fan controller (Davies Craig) that cycles them...I also now use an electric water pump (35gpm) and no thermostatÖ. still no issue

Re: Electric Fan Engine Cooling

I would let the sensor turn on at 180 and off at 175. No need for a separate switch imo

Where would you get a 180f on/ 175f off coolant switch? I have a Ron Davis setup with dual spal fans. Spal offers 2 settings for their stainless coolant switches. 195f on/175f off and 185f on/165f off. I have the latter but my coolant will never go below 165f in hot weather/traffic so basically always on unless coasting downhill.

Thanks in advance

Thanks I was looking at that a while back. For $15 more the newer version has Bluetooth so you donít need to crawl under dash for setting adjustments.

If I canít find a switch with on off settings I want I might just get one. Already have Dakota digital hdx so bim cable connection uses existing sending unit.

Re: Electric Fan Engine Cooling

Here's the one I'm running

Turns one on at the temp I set, with the other coming on 5 seconds later, then turns them off at the temp I set. So they'll cycle on/off like in a new car.

I use a Dakota Digital fan module. It turns my dual fans on at 205 degrees and off at 195. The fans get turned on when the A/C is on and the car is not moving or moving slowly. I have a Be Cool aluminum radiator.
