RosewillUltra Slim Case Fan 120mm Case Fan with Long Life Sleeve Bearing, Super Quiet Computer Case Fan with PWM (Pulse Width Modulation) Supported, 15 mm Thickness Very Thin & Low Profile, Black

Perhaps I got a defective fan, but this fan rubs up against the adjacent material that it's screwed to. I know it wasn't the fault of the dust filter I'd used, because the filter is aluminum and doesn't sag. Perhaps this fan was pro-rated to be in vertically-adjusted orientation but it's no good for being upside down (at the top of the tower) and it makes noise. It would not seem that good reviews of this product were valid based upon this. I'm dissapointed.

Revised: Complete utter trash.Original: This is by far the worst fan ever made. If I owned this manufacturer I would fire the entire assembly line, liquidate the assets, sell the property and buy a food truck to flip burgers because that's pretty impossible to screw up. This loud piece of junk clicks none stop because of its bearings. It's a total joke. On the package they have "long lasting bearings", I guess they made them long lasting so the fan noise can drive you mad as long as possible. It's not even a little clicking sound....its super loud! Like seriously, how do you screw a fan up this bad? It spins to push air. That's the only thing this object does and it does it terribly. It's such a basic concept I can make a manual one with a piece of paper. They must be joking right? The real one is still in the mail on the way?FYI if you need skinny (<=15mm) PC fans Amazon US has much better ones, they ship to Canada, and cost about the same.

The fan has a tilt when installed 'upside down' as an intake. Therefore the fan blade strikes the case, I had to raise the fan significantly from the case for them not to make noise, which is not ideal for positive case pressure, I have ordered a set of Noctura slim fans to replace these and will be returning.If you are using them as an intake I would suggest only using them for vertical mounts. On the plus side, they do push a decent amount of air when scaled with PWM and did provide an improvement in case temperatures [specifically GPU].

I needed a slim fan for the back of my case (exhaust) to clear my AIO lines.Very surprised with the volume of air this fan moves for how small it is and how loud it is.Granted its not quiet by any means at full tilt. But considering its moving 54cfm, you cant expect it to be silent. My Noctua fans are louder (they do move more air) but still. I'd say the noise level is appropriate given the level of air it's moving and how slim the blades.Also this is a PWM fan, when I'm not gaming my fans are at 20-50% load. In that realm it's silent.I'd urge people not to by this fan for a radiator or CPU cooler. As it's static presure is not great. But as a case fan, works perfect.I only used this in exhaust configuration. I see some people having clearance issues using it as an intake. So I can't speak to that.Price = CheapPerformance = GreatForm factor = Slim asLongivety, couldn't tell ya. This is all based on first impressions but so far so good.

This fan was exactly what I needed. I like that it was simple: no software needed, came with a power cable adapter for multiple option installation options, screws included, easy to install. It fit perfectly, runs pretty quiet, has good airflow and the blue LED lighting looks good. Very happy with this purchase.
