With summer temps on the rise and massive heatwaves sweeping the United States,  your engine could also feel the strain to keep the coolant from spewing out of the radiator overflow tank. That’s where today’s PROFORM’S new brushless fans come into play.

While the aftermarket industry has addressed these ongoing issues for years, PROFORM’s new brushless electric fans are the latest answer to these problems. While electric cooling fans are nothing new, it’s the research, design, and engineering that can make the world of difference.

But even the best fan or fans won’t cure all your ills if your cooling system is not up to snuff. Check out this StreetMuscleMag.com story for more insight.

Lightweight and powerful, PROFORM’s Brushless Electric Fans are engineered to cool any street machine in the most extreme conditions.

There are many factors to consider when it comes to choosing the correct fan for your particular application.

Muscle car purists typically stick with the traditional OEM-style five- or seven-blade belt-driven fan and factory-style radiator. But many street enthusiasts, hardcore drag racers, and RestoMod owners are more likely to upgrade the radiator to an aluminum unit and run one or two electric fans. We see this a lot in Coyote, LS- and G3 HEMI-swapped machines, and more enthusiasts than ever are looking to drive their vehicles and road trip to events like Power Tour, LS Fest, Sick Week, etc.

When it comes to custom builds and getting the cooling system dialed in, electric fans offer versatility, and flexibility, especially on engine swaps when space under the hood becomes an issue.

Ditch The Brush

The folks at PROFORM have now made electric fans even more efficient with their new line of brushless units. So, what makes brushless fans better than the traditional brushed units? First, brushless motors replace mechanical contacts with electronic communication, causing the magnets to attract and repel. With no brush contact, the wear and tear is reduced dramatically. No brush contact extends the lifespan of the brushless fan motor and also improves its reliability.

Another area where PROFORM brushless fans shine is their slow ramp-up, which means no amp spike. The demand is whatever the amperage is at maximum power. On brushed fans, they start instantly with a big amp spike, then run at some lower max speed and can be less efficient when cooling the engine.

Now, you’re probably wondering how brushless motors are controlled. It’s very simple, the
Brushless motors utilize Pulse-Width Modulation (PWM), a type of digital signal that
simulates analog signals by switching the output on and off at a very rapid rate. Most
brushless fans require the use of an EFI unit or proprietary electronic controller to
communicate that signal. Once again PROFORM has done their research on their brushless fans.

Unlike other brushless fans on the market, PROFORM brushless fans are totally
universal for 12-volt systems, eliminating the need for fancy engine-specific controllers. These fans also utilize a built-in advanced voltage regulation system to control the fan motor speed with a single-wire connection and it’s a very simple installation for any vehicle. There are six brushless fan models with CFM ranging from 2,100 to 4,200 that’ll move air like a hurricane under your hood.

These fans are lightweight (3.9 lbs. to 4.7 lbs.), have a three-inch thick profile to fit the tightest locations, reinforced glass-filled polypropylene blade with plastic housing and mounting kit.

PROFORM’s Multi-Speed Controller (PN. 67039) allows you to control the speed of the fans. It’s simple hook-up and can be mounted inside the vehicle.

Sing The Body Electric

“The electric fan has several advantages over mechanical fans in terms of performance. Since mechanical fans are belt-driven, the power is transmitted from the crankshaft. Therefore, the mechanical fan’s performance is tied to the engine’s RPM, and horsepower that would otherwise be transmitted to the wheels is instead going to the fan,” said Ryan Salata, Marketing Director at PROFORM. “Additionally, in low-RPM situations, such as at a traffic light, the fan may not generate enough airflow for the required cooling.

“Conversely, at highway speeds, the natural airflow is sufficient to keep the engine cool, and a mechanical fan may over-cool the engine, reducing efficiency and gas mileage. Since electric fans draw their power from the electrical system, they can be run more consistently at a set fan speed, especially with a thermal controller, without loss of horsepower. Taking it a step further, brushless motors offer advantages over brushed motors, including higher reliability, longer lifespan, and overall better performance.”

Ryan also gave us great info on how electric fans get rated which was eye-opening to us. “We rate electric fans by static pressure. Static pressure is created when something is blocking the air that the fan is trying to pull through. In automotive, that something is the radiator and any other coolers that are stacked in front of the fan. The CFM drop as static pressure increases. At PROFORM, we rate our brushless fans wide open, ensuring no static pressure, and we record a video to verify the accuracy of the number for potential purchasers.  Some fan manufacturers falsely advertise CFMs that are significantly higher than the actual values.”

These brushless electric fans come with a reinforced glass-filled polypropylene blade with plastic housing and include a mounting kit.

How CFM Is Calculated

PROFORM said it is transparent about the CFM performance of its brushless fans, noted
Ryan.

“Other methods electric fans get compared is the power of its motor, blade design,
speed, and pressure resistance,” he said. “All these should be considered, but PROFORM has done all that research in their new brushless electric cooling fans.”

So if your street machine is puking coolant on the side of your highway, or you can’t run the dial-in at the strip due to engine heat soak from hot lapping, PROFORM’s new brushless electric cooling fans may very well cure those problems.

PROFORM’s brushless electric fans will prevent your high-performance street machine or drag car from puking its coolant out this season.

Its electric brushless cooling fans come in various diameters (12-in., 14-in., 16-in.), CFM ratings (2,000-2,499, 2,500-2,999, 3,000-plus), and styles (S-Blade, Straight Blade). PROFORM also has its Multi-Speed Controller (PN. 67039), which allow  you to control the speed of the fans. It’s a simple hook-up and can be mounted inside the vehicle.
