ISR Performance Electrical Universal Radiator Cooling Fan - 12"

The ISR Performance universal 12 inch electric radiator fan is a compact, high-flow fan suited to SR20DET swaps and any 240SX that needs to move away from the clutch fan. It fits a wide range of radiators thanks to its universal mounting and can be flipped to work as either a pusher or a puller.

Sizing for a 240SX

ISR recommends running two 12 inch fans on 240SX and SR radiators. A single fan leaves part of the core without direct airflow at idle and in traffic, and a pair covers the width of a 240SX radiator properly. If you would rather not fabricate your own mounting, the ISR fan shroud kits for the S13 and S14 come with dual 12 inch fans already fitted.

Why go electric

An electric fan removes the parasitic load of the mechanical fan, frees up space in front of the engine on a swapped car, and lets you control fan operation with a thermostatic switch or your engine management. It also keeps airflow steady at idle, where a slow-turning clutch fan is least effective.

Wiring note

Run the fan through a relay with a properly sized fuse and a temperature-based trigger rather than directly off a switched ignition feed.
