GDSTIME 30mm Blower 12V 2Pin 3010 Dual Ball Brushless DC Cooling Fan 2-Pack

Bought these for a 3d printer. These things are NOT quiet at full speed, but they push A LOT of air. That said, you really do not need to run them at full speed, and probably actually shouldn't. They push A LOT of air for their size, and I found that at full speed I was getting GREAT overhangs, but my layer adhesion was suffering, i believe they were cooling the filament too fast. Cut fan speed down to 50% to 75% and have been getting great results with much less noise. haven't run an overhang benchmark again yet, but I am pretty pleased with these fans. The cords are also nice and long, I can;t imagine too many people will have problems getting them hooked up unless your rig has super long cable runs

These are exactly the fans I needed to repair my Xbox 360 power adapter. *However*, for anyone else looking for them for that purpose, do be advised that the polarity of the connector is inverted compared to what you need. The best way to fix this is to get a MOLEX Mini-Fit Extraction Tool and carefully swap the pins in the plastic connector. You don't NEED the tool to do it, but it makes it MUCH easier having the correct tool. For that purpose, these fans are also quite a bit noisier than the stock fan, so if that bothers you, pick something else. The cooling power can't be beat in this form factor though! They're also made with tough double-ball bearings, so they'll probably outlast the life of the console itself, lol.

I’m running two of these 5015 blower motors on my fan duct with great results. All the cooling you’ll need. The only negative is that they are a bit noisy/loud. I would purchase again.

Decent blower fan. I typically purchase my fans from Mouser, but I decided to try these. I found that they move the same amount of air and are the same sound level, pretty quiet. Overall, these fans work as I need and were a decent price. I am happy with my purchase...

I bought these to replace one on a super loud humidifier. I only needed one, but the price was better for the two than most places wanted for one. I had to de-pin the connector and use the original since it was a different style. Overall it works well, moves a fair amount of air, and is probably slightly louder than the original, but not bad.

This is the one you want. Blow enough air to cool prints. Don't get those cheaper ones or the silent ones. Get this one and set the fan percentage to whatever fits your need.i don't think there is a lot of 12volt fans out there that can move as much air as this.noise level is ok. Not silent but not as loud as the original anet one.

The first fan I plugged had a weird high pitch noise. Like a coil whine. It went away on its own as I increased the RPM. However, the second fan suffers the same problem that doesn't go away. Airflow is good overall. Definitely a hit or miss with questionable quality.

These 12v 5015 fans have much more air flow than any I've purchased previously and are as quiet or quieter than the next best I have. I was not expecting a one year return policy, but there was a slip of paper in the package that stated they could be returned for up to a year if they fail for other than a human error (wrong polarity or voltage would be the most obvious of these to happen). I'll have them installed by tomorrow and will see how well they endure my 3d printer work load.
