Yep! Even with the top down I cannot hear the fan.

As said the computer will then control your spal fan progressivly with temperature, and if you are inclined for coding the computer it can be adjusted. There are a few threads on this if you want to micromanage it. Im in FL and have used it all summer and had no issues w/ my temps even in traffic. The fan runs if your AC is on also if im not mistaken. Lastly its not at all noticable from inside the car while the fan is running. Outside you can tell its on but again the noise from this larger fan is a non issue.

Hope that helps.
Thanks, but I am trying to run the AUX fan with the SPAL as a secondary source once the car gets too hot

Why?

The aux fan only runs if the car gets too hot. If you delete the aux fan and run the spal fan off the aux fan controller, the spal fan will only run if the car is too hot.

Removal of the aux fan also allows more air to the rad, which helps at speed.

Most people run them together for additional cooling. I deleted my clutch fan a year ago, with a cooling system overhaul, and with just the AUX fan, my car never overheats at the track in 100 degree weather, nor in stop and go traffic with the AC on.

I want the AUX fan to function normally, but once the engine reaches 180 degrees, I want the SPAL to kick in as a secondary source for additional cooling.

Despite the extremely poor reviews? Seems risky.

Lol. What's risky about it?
The 2nd review said it was a bad batch.
The guy that told me about them use to run them on hot rods with 2 fans.

yea i looked at that one also, but the reviews sucked, so i stuck with a preset temp one.

Mishimoto uses this one with their kit, you need the probe unless you tap the coolant line.

Am I understanding that right. A water jacket sensor. Where and how does that thing mount? Where and how does it read temp?

Which prayer one do you run? I don't really need the adjustability.

Is this the non adjustable one you're running?
