5015 Cooling Fan (DC12V 2PCS)

It's no louder than the stock fan. The rattling isn't from the blearing or fan, it's vibration from the housing. Just dampen the vibrations by adding tape or fastening it down better. Works great.

I needed a replacement cooling fan for my CreatBot 450 PEEK 3D Printer. The factory fan make is SUNON and the part number is GB1205PHV1-8AY. After an extensive web search from reputable electronic distributors; Digikey, Mouser, Allied, ... The part seems to be "Discontinued." Ebay does have the part but it costs $21 with a 3 to 6 week lead time from China. (no, thank you)ONE NOTE: This fan does the job beautifully WHEN I SWAPPED THE LEADS.Upon inspection, the SUNON and YIOVVOM fans appear to have identical mechanics (likely the same molds for that matter) and the YIOVVOM fit right in.Again, there is something strange about the red and black leads - they are either swapped or miscolored (by convention) If your fan seems not to work, try swapping the leads.Up and running in 24 hours - Thank you Amazon.

The media could not be loaded. Worked really well for the first month but then one of the fans began vibrating excessively and loudly. Looks like the bearing gave out and even started leaking fluid. Could no longer be used.

Easy to install on my Ender 3 Pro. Used Thingiverse to print hotend shroud. Fan fit perfectly. Little louder than stock but prints turn out great.

These suckers blow! A lot of air. I saw other reviews where poeple used them at 90 percent on their 3d printers. I agree. In comparison to the original one these really move the air even more than the 10x40 noctua fan its replacing. Coupled with a fang they are perfect. Hooking them up was a breeze. I had issues with my prints but I found it was the filament. Too much moisture and the only way to print was high heat no blowerI had originally received 2 duds dead out of the box. But as soon as I let them know they shipped replacements. Returning them was a breeze.They work great. I honestly cant hear it over the other fans. Which are in the controller box. I now know where to order 5015s from... these guys.I am doing one mod at a time and will hook up the second one later. Though really, the one does the job. The wire connectors I borrowed from my noctua fans. Now I have a spare for both, parts and hot end fans.

It is just another generic blower fan so it is noisy.Purchased for 3D printer, I upgraded other regular fans on my printer to Noctua but decided to get a blower fan to pair with the rest of the upgraded fans. The noise level is horrendous when pairing with quality fans.

If you are buying this for a 3d printer with a silent board like I did, you can rejoice in the fact that your power supply fan is no longer the loudest part of your printer.Also pretty good at cooling off stuff. I used these on 2 setups. One is a hemera (single fan dual duct) and the other is the hero me v5 on a nearly unmodded ender 3 pro (single fan dual duct). Both had cooling improve by installing this but I am considering switching to dual fan dual duct on the bare bones printer because it prints very fast and may need more cooling.

Picked up a two pack for a 3D printer project I'm working on. I hooked up the first one, noticed it wasn't working, then was hit in the face with a burning electric smell. I pulled power as quick as I could. I looked at the fan to see if maybe there had been an obstruction or something keeping it from spinning, none to be found, spun freely. Ok, maybe the other one will work. Check the next one for free movement before wiring it up. Chugs and vibrates a bunch, struggling to even run, never gets up to full speed. 100% failure. Ordered a set from another seller, and worked fine. AVOID!
