Speed Parts Review: Proform Universal Cooling Fan


We handed our good friend Nick Taylor, owner/driver of Mailboost, some much needed parts to help keep his turbocharged G-Body cool, under the pressures of hard driving on the street and the track, and this is what we got…

Boy, did I love my previous fan, but it was time for it to GO…and that’s when the box marked Proform Performance Parts found it’s way onto my porch.

The old fan in the Malibu was pulling far too many amps and did not contain nearly enough cooling capacity needed for the punishment I was putting the car through at the track, let alone on the street, and it put me in the situation where I was forced to not run a thermostat in my motor for the past 3 years because it. With the old fan, I just could not move enough air through the radiator to keep it cool while trying to maintain a constant temperature.

Upon pulling the new fan out of the box, I could instantly tell that it would move twice the air of the old fan with a heavy-duty motor, highly angled blades, and 15″ diameter. The Proform fan has a much better shroud design to contain the fan blade, along with a high-quality rubber seal that will help control the air it’s moving considerably better than the previous set-up. With the rubber seal around the shroud, it helps maintain a low and constant amp draw on the fan motor since it keeps a constant load on it. Not to mention it moves a tremendous (this unit pulls up to 2,800 cfm) amount of air compared to the factory unit – twice as much, if my math is right. Proform also has incorporated an internal thermostat equipped with an adjustable 180°-240°F that is easily adjustable on the fly, and comes in handy when track conditions change from morning to night.

With the new fan installed and moving more air on demand (with the fore-mentioned internal thermostat) I will be able to hot lap the car, which in some classes is almost mandatory, True Street NMCA for example. Along with being able to hot lap the car, I can also really start to dial the tuning of the car due to having a more constant coolant temperature.  That has a lot to do with the tune and fuel graph. The more variables I can make constant (coolant temp for example) the more I can start to lean on the tune and crank up the power – you might not always look at your cooling system as a source of power, but it does all work in unison, and we all know that the cooler your engine, the happier it is…

Here is the in-house video from Proform Parts – to give you their insights.
