WINSINN 5015 Blower Fan 24V, 3D Printer 24 Volt Fans Blower Turbine Turbo Dual Ball Bearing, Brushless Cooling 50mmx15mm 2PIN (Pack of 2Pcs)

I'm using both of these on a low cost Sovol 3D printer, and they improved a small problem I had with prints failing due to heat creep, and separately, with poor performance when printing bridged areas. With the two fans installed (and after printing two small adapters, available on printables.com or thingiverse), the printer performance is much better and bridging is especially improved.Note: these fans are rather noisy. If you have an enclosure you probably won't notice, but if your printer is in an office setting, you certainly will. I have some dielectric oil and applied a tiny amount but it did not help. They're just a bit noisy. But it's worth it, given the performance improvements.

I bought these to replace the parts cooling fan on my creality cr-200b. I am only using one. So far I have ~200hrs run time on the first fan w/o any issues that leave me concerned. I print a lot of ASA in a heated enclosure so the fan is often in higher than ambient temps (40-60c enclosure temp). I will update this post if there are any premature failures.Noise is higher than the stock parts cooling fan, however it is still relatively quiet (much quieter than the stock hotend fan - I don't even notice it). Air volume is much much higher than the stock parts fan.I've been able to double or triple my PLA print speed, with far better overhangs and bridging. This should be the default fan solution for printers imo. The 4010 just can't keep up during the warmer months.

One star off for noise, seems 3x louder then my oem on my humidifier. Also the plug is wired reverse of my humidifier, but sold for printer format. Chessy plastic on my humidifier socket, was able to simply force on in reverse direction. Could have just filed down the side pins too. No speed rpm listed.

Nice little fans, I was quite surprised at the air they move for their size.

Success running dual 5015 fans on an SKR Mini E3 V3.0!Get these fans and only these fans (others are weaker and will break themselves and the SKR,) compile firmware with the following changes:Configuration.h#define FAN_SOFT_PWM // makes them not blow up#define SOFT_PWM_SCALE 2 // best for noise#define SOFT_PWM_DITHER // get linear rangeConfiguration_adv.h#define FAN_MIN_PWM 48 // the best value for only a bit of air (lower at your own risk)#define FAN_MAX_PWM 255 // full blastRemove current cooling fan, cut the blue and yellow wires, connect (ideally solder) both fan's red wires to the yellow one and the black ones to the blue one. Attach fans very securely - I highly recommend Thingiverse thing:5750189 for a fan shroudOnly need to run fans at about 50% during the print and I'd set the first few layers at 0%, 2%, 10%, 20%, 30%, 50% and keep it for the rest of the print

I had to solder the wires to the fans. I had to modify a fan mount because one fan was a little larger than standard 5015 fan.

I upgraded my part cooling on my Ender 3 with two of these fans…Amazing performance - I can’t recommend them enough. No coil wine and no rattle so I’m happy. For some reason I thought you only got 1 fan with the purchase of a single quantity - so I was surprised to find I accidentally ordered 4 fans instead of just 2. I’ll save them for future projects so I don’t mind.

LOVE Winsinn fans. They've all been reliable and consistent for me. Before going with these ball bearing 5015's, I bought the hydraulic bearing ones. They're cheaper, but they're still great. These ball bearing ones are just a step above the hydraulic ones, and they're worth it. Quiet, consistent, powerful. Love them. I use them on 3D printers, but nonetheless, great fans.
