BLACKHORSE-RACING 12ft Electric Radiator Cooling Fan Kit - Universal

In this review of the BLACKHORSE-RACING 12' Universal Electric Radiator Cooling Fans kit, the bottom line is simple: it is a practical, low-cost auxiliary cooling solution for hobbyists and everyday drivers who need extra airflow in tight engine bays. The reviewer found the kit most useful as a supplemental fan for radiators, intercoolers or transmission coolers rather than a primary cooling system, and highlights the kit's slim profile and included thermostat relay as the single biggest reason to consider it.

Key Features

• 10-blade 12V fan: The 12' fan with ten blades is designed to move a lot of air, helping lower coolant and surrounding component temperatures when installed as an auxiliary fan.
• High airflow: Rated for up to 800 CFM and a maximum RPM of 20,000, the fan can deliver strong airflow for spot cooling smaller radiators and intercoolers.
• Slim design: At about 2.36' thick the slim housing makes it easier to fit into congested engine bays without interfering with other components.
• Thermostat relay kit: The included thermostat probe and relay switch the fan on at 180'F and off at 165'F, providing automated control to protect the engine from overheating under load.
• Complete mounting kit: Mount brackets and tie straps are supplied so the fan can be secured to different radiator setups without sourcing extra hardware.

Who It's For

This kit is aimed at DIY mechanics, weekend racers, and owners of older vehicles who need a compact, universal auxiliary fan to supplement cooling. It works well for radiators, A/C condensers, intercoolers, oil coolers and small transmission coolers where added airflow helps performance or prevents heat soak.

Those who should look elsewhere include owners who require a drop-in, vehicle-specific primary cooling fan or who need a guaranteed solution for sustained high-load track use; some users reported mixed cooling results under extreme conditions, so a dedicated factory replacement may be preferable for heavy-duty or long-duration racing applications.

Pros & Cons

Pros

• Good value and perceived build quality for an accessory fan kit.
• Useful automated control from the 180'F/165'F thermostat relay for hands-off operation.
• Slim profile and included mounting hardware make installation practical in tight bays.

Cons

• Cooling effectiveness is mixed in extreme or sustained high-speed applications; some users reported overheating in intense track conditions.

Our Verdict

The BLACKHORSE-RACING 12' fan kit is a sensible, budget-friendly auxiliary cooling option for DIYers and drivers who need extra airflow in cramped engine bays. With a slim profile, decent airflow and an included thermostat relay, it offers good value as a helper fan, though those needing a primary, heavy-duty cooling solution should consider vehicle-specific or higher-capacity options.

Frequently Asked Questions

Will this fan fit any radiator?
The fan is a universal 12' unit intended for a wide range of radiators and coolers, but fit depends on radiator size and mounting space; use the slim thickness to assess clearance.

What temperature does the thermostat use?
The included thermostat probe turns the fan on at 180'F and turns it off at 165'F, and it comes with a 3/8' NPT probe plus a 1/2' adapter.

Is wiring and installation easy?
Installation is straightforward for someone comfortable with basic wiring and mounting; instructions are provided in the main image but customers sometimes request clearer wiring diagrams.
