Coolerguys 12V Ultra Quiet Fan For Pi Devices, 3D Printers, And Microelectronics (40X10Mm) Review

Once the sleeve bearings broke in and stopped screeching, very quiet. But I don't see how they can cool anything. No mounting screws provided and the holes are non-standard so standard fan screws split the mount.

I made the mistake of buying winsim fans. Two out of the five were bad and the third one I put in was the loudest thing I’ve ever heard coming from a device!But this Review is about coolerguys fans. I put it in the system and it was a great replacement. I’ve had one fan that was slightly quieter than this one, but this is still more quiet than the hot end fans anyway. I will be buying them again when needed.Thanks!

I'm using this for my propane fridge, it uses almost no power, very quiet, and for my use it is perfect. The amperage is like .010a. I'm living off-grid so the less power i use the longer my batteries will last.

Fan is about 4000 rpm which is lower than the 8,000 rpm ball bearing fans I purchased earlier, which were incredibly noisy.This looks to be an exact replacement of the OEM part and is almost silent in operation which is exactly what I wanted. It moves a low volume of air but that’s what i needed for a low heat generation device. I am concerned about the lifespan relative to the ball bearing motors, only time will tell on overall lifespan.So far very happy with this product.

There is a review below that complains about noise? Just got this today and installed in my NVR and There is 0 noise from it! you will need to swap the plug on the end or splice the 2 wires. Took about 10 min to swap the fan!Hope this helps

Great replacement fan for my battery charger in my RV. Quieter than the original fan. Now if it lasts a couple years I'll be happy! So far it's great.

The first of thing from being ultra quiet. Installed in a LG home theater, when it comes on, drowns out the sound of the TV. The compensate for the extremely loud air flow noise I cut out the air great on the back of the home theater system but it's still too noisy.

ordered 4 coolereguys ultra quiet fans. got 4 wei wang zin fans. loud. i now have 4 loud fans in my livingroom on the fish tank fluorescent fixture. great. powerful quiet in the test. installed and vibrate like heck.

Absolutely amazing! Whisper quiet which is just what I needed for a piece of studio and stage equipment.I’m recommending this to a group on social media who need the same solution as me!

I should have read closer since I needed something with higher flow rate. This is very leisurely. Good if you're in a glovebox and don't want to mess with a balance or powders too much. Not so great for pulling air through a packed bed. It's very very quiet, barely noticeable.

I install this in the power supply of my 3D printer. Worked okay for two weeks, then suddenly got noisy. May not be strong enough to cool certain devices.

Its been a week since I put this fan in my cr-10s case and its already chattering. Totally junk in my opinion. Guess I need to find a better brand.

Was replacing the fan in an Akitio Thunder2 enclosure (SunOn Maglev Fan). It was decently quieter, but had a noticeable tick up close. Not as good as I hoped, but it'll do.Was nice that I could get a model with the 2-pin connector and good cable length so it was just an easy swap.
