Review on 🌀 Cooler Master 80mm Silent Fan with Sleeve Bearings for Computer Cases and CPU Coolers by Tom Schuster

I couldn't find a better deal. These fans are great mid-range fans. Since these are sleeve bearing fans, they MUST be used vertically. If you use them horizontally, they get very noisy and fail within a few months. (This is NOT a Cooler Master design flaw, it's just how the bearings work!) I had to replace 3 fans on my PC heatsink and they fit the bill and work better than the ones that came with my EKWB EK-CoolStream XE 360 were delivered. (Triple) liquid cooler! They are 3 pin MB style connectors so keep that in mind when you buy them. Pros: Moves a decent amount of air Fairly quiet (unless you max it out) Good amount of cables to work with Cons: No sleeved cables (which is what you'd expect from a cheap fan) A little noisy at high speeds ( if you have all 4 in one little case price per product i can't take anything away from these fans i've been using them for 6 months now and have no problems they keep my system cool well someone said you can't install them and keep them they pretty May I suggest: Cosmos ® 12 pcs Black Rubber for PC CPU/Chassis Fan Mounting Screws Rivets
