Everflow 70x70x10mm Ultra High Speed Dual Ball Bearing 12 Volt PWM Fan R127010BUAF

Used to replace fans on an old LIAN LI PC-C37B Micro ATX HTPC Case. This case has been excellent but uses odd sized fans one of which began making horrible noises. I used three of these fans to replace the original two fans. They are quiet and I believe I have improved cooling air flow as I have more fans. I used a splitter to drive them all off one MB PWM header and control the speed with speed-fan. Quiet and move plenty of air as needed dependent on CPU temp.

This fan is an unusual size, but Coolerguys is good about stocking unusual sizes and making them easy to find. This fan is getting the job done as a CPU fan in an embedded server. Nice to know it has a high max RPM just in case, although I'll be running it at a lower RPM. I did have an issue where I received a 3-pin fan instead of the 4-pin PWM fan described in the Amazon listing. The seller, Coolerguys, was very responsive about fixing the issue and sent me a replacement fan directly at their own cost. Apparently, with this manufacturer, the 3-pin and 4-pin fans have the same model number on their sticker, which is understandably confusing. Based on this experience, I will personally go out of my way to shop with Coolerguys in the future and can highly recommend them to others.

This is a really impressive slim fan in an oddball 70mm size. If you can't fit an adapter or literally anything else, this is your answer. Just know that absolutely WILL be loud when it ramps up over 5k RPMS to move air. Still, this moves as much air as a higher end full thickness 80mm.

This fan does the job and was easy to install as a replacement for the existing fan. Delivered promptly.

on the plus side it spins. on the down side it's grinding out of the box. loudest fan ever. if it weren't in a closet i would return.

Fast shipping and great sale by coolerguys, however I wish I would have looked at product pictures a bit better as the solid pipe style pass through for the screws rather than individual holes on each side of the frame kept me from installing this fan with the screws for the delta it replaced just something to consider when replacing a small fan such as this.

The fans are great, powerful, slim, small and move a ton of air. Ball bearing design so should last forever. I did get a dud that died after 3 months but the sellers are amazing. They promptly sent replacements and kept me up and running. Thanks so much CoolerGuys!

Good strong fan my sons pc is running cool 😎
