6500 RPM Fan for AntMiner DR3 L3+ S9 S9i S9J S9 SE S11 T15 S15 Z11 S17+ S17 Pro S17e DR5 D7 Z9 AsicMiner Misieren BRUSHLESS SHLF1212GHE-07, V12E12BS1B5-07

These fans work very well. Each five large blades with a distinct curvature to the face allowing it to "scoop" in or push out more air. There is also more air flow compared to the stock Bitmain fans with have much smaller/shorter blades. Although these generic fans are rated to 6500 rpm, they have never needed to go that high, due to the very good air distribution, even when operating the L3+ in hot summer months.

Quieter and Really Smooth, especially at the slower speed, at any rate, exactly what I spend hours deciding on and hoping for! Definitely Recommend, my personal recommendation, two thumbs up.

Received next day after orderingWorked exactly as expected

The fan was a direct replacement for my s19j but i had to move the top fan to the bottom because the leads are too short to be used as a bottom fan. The leads were about 4 inches too short.

Used in Antminer S9's, the headline says it all. This is the third fan of this brand that has blown itself up in service, over the last 6 weeks.These were all at the exhaust end of the miners. Ambient operating temperature varied from 21C to 38C, averaging 31C.I was lucky this didn't damage the hash boards.

Decent fans for the price. A little rattle in between 25% and 30% load though. Cools my l3+ effectively.

You need to cool something down this is what you need!

It works just like what it claim to be
