Pros: These come out to 3 bucks each after rebate. They both work. They both move a little bit of air but I don't believe 40cfm.
Cons: I have 7 case fans and these fill only two spots so I was not extremely concerned with how much air they moved I just wanted to fill the last empty spots with more matching led fans to match the rest of my case. The problem I have with them is they are much more of an electric bright blue than th...
Summary: As far as doing the job they worked fine, I just wasn't a fan of how plastic-y they felt so I ended up giving them away after about a week of use. But you're getting two fans for ten dollars so what can you expect.
Pros: I've had two of these for about 5 months. They push an alright amount of air, I like the blue light.
Cons: I have these fans placed horizontally (bottom case fans), and they make a lot of noise when at maximum speed. They make a sort of "clicking" sound. I was okay with this for the first few months, but recently theyve started to emit a very high pitched noise, which is so annoying ill have to buy ne...
Summary: Works well for a time, and maybe I just ended up with a bad pair, as the reviews seem to be overwhelmingly positive. Unfortunately it appears I'm past the 1 year warranty period.
Pros: Worked great, they were quiet -as quiet as something can be considering its a fan- the LED looks cool, and it was a great value
Cons: Well 1.5 years after purchase they appear to be failing. One of the two fans started making a loud buzzing noise and I was forced to remove it. I attempted to clean it out really good but it is still very loud. The second fan, while not loud like the first, is also emitting an annoying sound. I'm...
Summary: I did have to drill the screw holes a bit bigger due to the attachment method my side window/panel uses to keep the fan attached. I imagine with the screws the holes would widen themselves via the screws. That is not really a Con though seeing as I have drills and it is an easy fix.
Pros: I am only using one of them at the moment, but it brightens up half of my case and is surprisingly cool and very quiet. I love these fans!
Pros: Installed the new fans within a couple minutes, bright blue, silent (even when turned up a bit higher than normal), and seem to be much sturdier and blow harder than the fans that came with my case.
