I purchased the 'quiet' 5015 fans, the 'high speed' 5015 fans, and the 4010 fans, all from WINSINN for comparison. My focus was for a parts cooling setup for my Ender 3 3D printer. I was addressing noise generation, physical size (for printing multiple parts one at a time), and air movement - both restricted and unrestricted. These qualities would determine what kind of cooling system I would decide upon.This weekend, I will try to supplement this review with db readings from my smart phone app and some kind of repeatable test for air movement.In my unscientific tests, I found the 'high speed' 5015 fans to be the loudest, the 4010 to be the middle noise, and the 'quiet' 5015 to be the quietest. The 'high speed' 5015 fans were too loud for me, while the 4010 being pretty quiet, and the 'quiet' 5015 fan very quiet.In that same order did they seem to move air, both unrestricted and restricted. However, I found that 'high speed' 5015 fan and the 4010 to be pretty close in restricted air movement. The 'quiet' 5015 moved too little air for what I think I need for parts cooling on my Ender 3, especially when restricted. The air movement was unacceptable.After testing all three fan types from this brand, I deemed the 4010 fans to be the best in terms of noise generation and both types of air movement. I was actually surprised how much air the 4010 actually moved.So, for parts cooling on my Ender 3, I chose two 4010 fans for the lack of noise generation, size, and ability to move restricted air.These other blowers are not bad at all, they seems to have good build quality. But, not what I was looking for.
