Review: good value - Good replacement, aloud louder than the fans i replaced but the ones replaced were failing so could be that.
Review: Work as expected. - I have purchased these fans to cool off my fiber optic modem which was running quite hot. I selected this size to fit my 40x40 mm aluminum heat sinks. The goal was to cool it down below 40.0C (104F). I'm running all four fans at about 70% speed per manual external power controller. This keeps the device's external hot spot at 37.1C (98.8F). Before I used any fans, the heat sinks alone did not do much, although they did get quite hot too. I needed fans. Either way, at the time, the device was hitting above 47C (116.6F). The fans move enough air for a small size and my application. My room ambient temperature at the time of measurements was 23.5C (74.3 F). They are definitely audible at 70% speed. My room ambient noise floor average was ~26.4 dB at the time of measurement. 4 fans on at 0 distance blend in with the background noise ~10% speed 4 fans on at 0 distance average about ~40.1 dB ~70% speed 4 fans on at 0 distance average about 44.8 dB ~100% speed The time will tell how long these will last as all four are on and running 24/7 since the day of the purchase.

## Questions & Answers

**Q: How come does it say it's quiet but there's no dba mention in the listing? How am I supposed to know its noise level?**
A: One of the pictures shows the dB as 18. Typical background noise in a quiet room like a library is 30dB so you aren't going to hear this unless it's close to your ear.

**Q: Does this set have 4 (four) 12V fans?**
A: It depends on the "color" you order. I purchased the option with two 5v 30mm fans, but four 12v fans is one of the other options. Just make sure you order the correct 
"color" option.

**Q: Will the fan work fine with 13.8volts?**
A: It should but I would go for original part replacement

**Q: What gauge wire are these?**
A: Hi, these gauge wire is PH 2.54.
