MOSTPLUS Black Universal Electric Radiator Slim Fan 7in Set of 2

In this review of the MOSTPLUS Black Universal Electric Radiator Slim Fan set, the bottom line is straightforward: this kit is for anyone who needs a compact, high-flow cooling solution for tight engine bays or swapped engines where space is limited. The reviewer found the pair of 7in slim fans deliver strong airflow and a solid motor package for their size, making them a practical choice for radiator or condenser assistance, provided the buyer plans on professional installation and verifies fitment before ordering. Overall, this is a functional, no-frills cooling kit aimed at installers and experienced DIYers.

Key Features

• Slim 2.5 in profile: The thin assembly makes it easy to fit in constrained spaces behind slim radiators or in engine swaps where clearance is tight.
• High airflow: With a rated maximum CFM of 1200-1600, the fans move a significant volume of air relative to their 7in diameter for improved cooling under load.
• Powerful motor: Each fan uses an 80 watt motor with a top RPM around 3000, providing consistent performance for demanding cooling needs.
• Set includes mounting kit: The package includes two 7in fans and two mounting kits, which supplies basic hardware needed to secure the fans to a radiator or shroud.
• Moderate current draw: Drawing roughly 5-7 amps per fan, the unit balances strong airflow while remaining compatible with typical 12V automotive electrical systems.

Who It's For

This set is best for vehicle owners doing engine swaps, radiator upgrades, or those needing supplemental cooling in a tight area where standard 10in-plus fans cannot fit. Professional installers and experienced DIY mechanics will appreciate the compact dimensions and included mounting kit when integrating the fans into custom setups.

It is not ideal for someone who expects a fully plug-and-play consumer product with instructions included; there are no installation instructions in the box and the product recommends professional installation. Buyers who need extensive guidance or a manufacturer-backed installation manual should look for a kit that includes wiring instructions and step-by-step mounting documentation.

Pros & Cons

Pros

• Compact 2.5 in thickness allows installation in cramped engine bays where larger fans will not fit.
• Strong reported airflow and cooling performance for 7in fans, useful for radiator or condenser assistance.
• Included mounting kit provides the basic hardware needed to secure the fans to many applications.
• Reasonable power draw of 5-7 amps per fan keeps electrical load manageable on most 12V systems.

Cons

• No installation instructions included, which requires professional installation or prior wiring experience.
• Some customers have mixed feedback on long-term durability, so buyers wanting extended warranty reassurance may look elsewhere.
