SPAL Radiator Fan vs cheap eBay fan

Ever wondered how a genuine SPAL High Performance radiator fan performs against cheap eBay fans? We found a few people who use SPAL fans that were eager to find out too!

In the video below you will see the tester comparing a 14” SPAL fan like the ones we sell here at Performance Airflow with a cheap generic brand eBay fan.

He first connected the fans a power supply showing 13.8 volts on the voltmeter (see image) - which is roughly what your vehicle will be pushing out when the alternator is running.

First up was the cheap eBay fan. When this was turned on it looks like there isn't a lot air coming through and the card is hardly moving at all.
