Proform’s 15” Thermostat Fans Are Back


After nearly a two-year hiatus, Proform’s hugely popular 15” thermostat fans are back. A complete redesign plus some new tooling have resulted in a sleeker shroud, more modern circuitry, and a wider range of temperature adjustability. No doubt, the completeness of these fan kits is surely part of what made them so well-liked in the first place.

To start out with, the thermostat is built into the housing. No external module or wiring accessories are required, thereby greatly reducing installation time and difficulty.

Plus, it helps clean up the engine bay aesthetics. Just wire it up and turn the built-in dial to adjust kick-on temperature from 160° to 240° F.

The included brackets maximize versatility in that the fan can be bolted or clamped onto the radiator. Furthermore, it can be mounted either vertically or horizontally, depending on what works best for the application.

These air movers are universal and can be had with straight blades (P/N 67017) or S-blades (P/N 67029). Both are rated at a stout 2,800 CFM with overall dimensions of approximately 16.5” wide by 18.5” tall by 4.25” thick.

However, the S-blade model will be slightly quieter for those that prefer the purr of the engine. For those that are running open header big blocks, the straight blade’s more noticeable whirr might be just fine. Either way, with an electric fan design that’s this turn-key, why not save 10 or 15 horsepower by ditching that old mechanical spinner?
