Pack Of 4 Dorhea Brushless Cooling Fans - 60X60X10Mm DC 12V 6010 Ball Bearing Replacement For DIY PC Computer Case Fans - 2 Pin Connector For Enhanced Cooling Efficiency Review

Bought these to make a DIY RV fridge evaporator fan. They work great for this! They draw a tiny amount of current and I can't hear them running at all. They move enough air over the fins to help the heat exchange.Handle these with care, the hub supports aren't indestructible.I may add more.

I searched for 60x60x20 but these 60x60x10 showed and I didn't notice they were the incorrect size. I made up for the amazons poor search engine and put two fans in line to fit the space. It worked out OK anyway.

They have Brass Bushings . Arrived fast and in good shape . All worked and blow OK air flow. Not strong enough for my project , so I ordered a Ball Bearing Fan that has much higher air flow . It costed more than all 4 of these , but it is like they say . I will use these on less demanding job .

Need a fan for a small project. Glad they came in a pack of 4 cause 2 didn’t work straight out the package Used these in a NVR for case cooling.Installed Nov 2020, dead by May 2021.

I bought this to replace the loud PSU fan in my Voxelab Aquila hoping to be a bit quieter. It didn't make much of a difference if any at all. If you are looking at this fan for this specific reason, look elsewhere. I know it doesn't say "quiet" anywhere, but I'm docking a star for just how loud this fan is.

I bought these little things for radio and SBC purposes. They do work just fine.I have only one real complaint and that is noise level. They are a bit noisy for how much air they DONT move. You'd expect a bit more CFM from the noise, but. hoping it is quieter once placed in project case, and installed under seat of truck. I use one of these on a raspberry pi4. I am able to keep device cooled to about 45°C. That is with moderate to high processor use. Ambient air temperature has been 16-30°C.Fan

Purchased the 4pk of these 60x60x10 fans for their small size and low dB levels at this low price. Ech one I have installed smells pretty strong of electrical problems upon first supplying power to them. it does dissipate after a time but it will really make you think that you seriously messed something up for a minute. Haven't had one fail yet, but they don't move very much air either so probably not running very high RPM. wouldn't place these anywhere where cooling is super important but if…

It functions well, but doesn't quite work in my intended application due to higher-than-expected noise level. I did not measure sound level in decibels, but it was audible from over 10 feet away in an otherwise quiet (but not silent) room. That would be tolerable by itself, but the timbre of the fan is a little irritating.

Got these to replace the 24v fan on a big LED unit. The 4-pack was cheaper than I could find a single. The fan moves a lot of air at 24v. There is a whine from the high-speed blades, but it's not noticeable from 30'.

Installed 2 of these in my surveillance NVR as replacements and both failed in less than 2 years. One seized and the other has a bad bearing rattle in it and it's not long for the world. They were fine while they lasted, but they have very poor longevity.

I bought it to replace the FAN of a Disk Enclosure, some how this fan was even louder than the original one.Quality seems to be OK for the price.

This fan actually draws 95-100 mA at 24V (2.4W) despite being rated at 0.6W. It produces much less airflow than the 2.4 W fan I was replacing though. But the main reason I bought this model was the hope for ball bearings, witch it does not use.

I bought these to replace failing fans in an NVR power supply. NVR power supplies are very expensive, if you can find them and it seems silly to replace the NVR just because the fans are failing. These were so quiet, I thought the power supply failed. Since they were so quiet, I replaced the other case fans. The $15 spent on these saved my client $300 for a new power supply or $800 for a new NVR.

These fans circulate enough air to prevent mold and crown rot inside a 4X2" grow box and I can barely hear them running. That's my feedback!

Had a fan that started making noise shortly after install, contacted merchant and got no response. Dont waste your time on this junk, buy from another seller who is responsive and doesnt sell garbage product.
