Opinions on PWM fan controllers

Correct me if I'm wrong and things have changed since I purchased about 3 years ago but my Vaporworx controller is made by DC Controls. DC Controls also makes a nice PWM controller, one of if not the first PWM aftermarket unit to the market that I can recall. I've installed 4 of them over the years on friends cars and none have ever had an issue.

However, as the OP mentioned, he wants a thread-in style probe and DC only makes them with a dry-style probe for direct fin contact. While I'd also prefer a thread in wet-probe for cosmetics in reality DC's dry fin contact probe works *extremely* well and the unit is very accurate and repeatable. I'll let the fin-probe slide because the rest of the unit works fantastic.

Check out the new Derale PWM fan controller. I can attest to the robustness of the design and function ;-)

It has a screw in option for the sensor as well.

What can also be done with excellent results is to take the DC Controls press-in sensor, remove the covering, and epoxy it into a fitting. On the Camaro an old temperature sensor was gutted so only the brass housing remained. The sensor was then potted into the sensor body. A 3" pigtail/plug was added to make installation easier. Has worked flawlessly. The sensor is small enough to fit in quite small NPT fittings as well.

Carl, are you using the Derale 16795 controller? http://derale.com/products/electric-...n-probe-detail Are you using one controller for 2 fans and AC or more than one controller. Thanks for any info.

I have an older DCC version in the Camaro. It drives a Mark VIII single fan and no AC.

If memory serves the Derale part has an AC override function and can drive multiple fans at the same time.

Interesting idea.

Carl, do you know if it is ok to put a connector on the dcc temp lead? I want to put a weatherpack on it so i don't have to pull the sensor out of the rad fins.

That's what was done on mine since screwing in the modified sensor would be tough. Try to put the connector on such that it can be supported by zip ties, clamp, etc. The weight should not be supported by the fit of the sensor.

Thanks for the info!
