Review on 🌀 High-Speed 24V Hydraulic Bearing Brushless 30mm Fan - WINSINN 3010 (Pack of 5Pcs) by Justin Guldin

Purchased for Ultimaker 2. One was for cooling the E3D v6 clone in the print head, the other two were for layer fans. Pros: I think it's pretty quiet. Cons: These things created almost no airflow. Considering their price I wasn't expecting them to have the wind tunnel performance of the Delta - however I wasn't expecting their airflow to be so poor that I didn't feel any wind coming off these fans at all. . The fan cooling my hot end was so inefficient that I started getting excruciating heat and eventually the PLA got stuck in the thermal barrier, PTFE LINED HEAT BREAK. Two-layer fans facing the same area produced virtually no noticeable wind. To be honest I think my background boost would cool both the hot end and the part more efficiently. I'm not sure what application these zero airflow fans were originally intended for. I can't think of any. This is definitely not enough for a 3D printer.
