“I found the assembly quite finicky, and the fan is very noisy. Because the fan leads are stuck together, you can only use pins 2 and 3 (the 5V pins combo). I attached a different fan where the pin connectors are not stuck together, and am using the 3.3V pins, so it's nearly silent now. I would give this product 5 stars if it was easier to assemble, and the fan connector pins weren't stuck together (so you can attach the fan connectors to different pins to make the fan quieter).”
