## Questions & Answers

**Q: Is this fan UL compliance?**
A: Not sure as it is a 12Vdc fan. I purchased one of these to circulate cool air thru my "inter cooler" I built to cool the inside of my car while it is sitting out in a parking lot. That way I don't have to get into a hot car to drive home. FYI, it is powered by a  solar panel.

**Q: Do I have to get a thermostat or speed control or can I just wire them up to a 12v lead and ground? Im using in a car audio setup to cool amplifiers??**
A: Yes, you can using in a car audio setup to cool amplifiers.

**Q: UL compliance?**
A: Great fan, still working just great.

**Q: Does the fan have an automated temperature shut off?**
A: No those fans always run constant that’s what you want when the pc is running keep it cooled

## Customer Reviews

### ⭐⭐⭐⭐⭐ Fixed my noisy PSU
*by J***B on February 10, 2025*

Bought this to replace that fan in my 850w NZXT brand PSU that I've had for maybe 11 years now. My original fan had developed a rattle. I didn't want to replace the power supply as it was fine otherwise.The specs for my fan were 0.5a and 2500rpm. This fan was the closest I could find on Amazon to the original spec. It works perfectly. Even though it spins a bit faster it is pretty quiet. No louder than my original anyway.Solid buy.

### ⭐⭐⭐⭐⭐ Quiet
*by I***S on April 3, 2025*

They move good amount of air and are relatively quiet.

### ⭐⭐⭐⭐⭐ Excellent OEM Choice
*by T***E on May 10, 2025*

This item was a perfect replacement. I used it to replace the cooling fan in bottom of upright drink cooler. My drinks were cold again. It hooked up just like the old one I took out. Very easy to replace.
