SoundOriginal 2pcs Cooling Blower Fan DC 12V 0.15A 50mmx15mm for Laptop Humidifier Aromatherapy and Other Small Appliances Series, PC CPU Server Dissipation and so on-Repair Replacement

I have an older 3D printer (Monoprice Maker Select V1) that had heat issues and couldn't print PLA worth anything. It was also getting clogs due to heat creep. I printed some extra parts using my newer printer and installed these two fans, one for the hot end and one for part cooling. They aren't quiet, but I don't think any blower type fan is. They did move a lot of air though, and they solved my issues. Fans work fine at 100%, and also work fine adjusted down to about 20% speed (and possibly lower, I didn't test any lower than 20%).

Using this as a replacement part cooler for an Anycubic i3 Mega-SSo far works great... too good in fact.. I need to keep it under 50% or it cools too fast.Even at 50% it's much quieter than the stock fan and moves much more airI'm only using 9V as well with no issues... spins up fine

I bought these fans for use on a 3D printer. Unlike some other fans that I bought for it, these do work fine with PWM control so they satisfied my requirements for a material cooling fan. I gave them four stars because I would have preferred a little more airflow, but they are doing the job fine, so if this is your application, buy them with confidence.

My xbox 1 power supply fan quit this fan was the perfect size and works exactly as the original thanks will definitely be ordering another set from this seller arrived is more then reasonable time

Used as a layer fan for my 3D printer project. Definitely audible but the output is good. Double check polarity of your application; I had to reverse the pins to use it on a MKS Gen L board.
