ENERMAX Twister Pressure UCTP12P High Static Pressure PWM 120mm Case Fan w/ Adjustable Peak Speed Function

Pros: I bought these fans to go with an AIO I bought from enermax and bought 4 and I am sold on these. they move air more than any fan on the market. and at such a great price i filled my case with them. At there full 1800rpm speed they have a little noise to them but it is mostly wind noise and when on a radiator they are dead silent. and i had 1 fan that had a slight noise and emailed there tech support and had a new fan the next day no questions asked. I was shocked on the delivery of it.

Cons: wish they came in 140mm sizes. and maybe rubber mounts on the corners. really nothing to complain about. switch placement on rear of hub cant be accessed once fan is installed on a radiator.

Pros: Quite and pushes some nice air flow through rads Black with a nice look to them. Not cheap looking.

Cons: Not really a con at all but can get a little loud when ramped up but thats any fan. but thats like maxed out. and they NEVER get like that on their own. more my mobo fault at start up.

Overall Review: I got these to push more air through my Corsair H105 as it has a thicker rad than most aio coolers. Did the trick pretty well for not much $$$

Pros: Very quiet at low and medium speeds. At high speeds, they move massive amounts of air while being mildly audible.

Cons: Over the past year or so, I have had to RMA three fans because they developed a rattle that got progressively louder. One fan seemed as if it all of the sudden became out of balance and vibrated loudly.

Overall Review: When these fans work, they are honestly the best fans I have used. Have five in my gaming PC, three in my living room HTPC and two in my bedroom HTPC.

Pros: 1. Those fans honestly move a LOT of air. 2. Good pressure 3. Not loud,,,,, surprisingly. 4. cheap ish 5. build in 3 speed variable speed. 6. sleeved 4pin connector.

Cons: 1. NOT 80CFM as advertised. 2. NOT 25 Dba 3. moves a lot of air and isn't loud, BUT no where close to 80/25

Overall Review: A lot of air is directed outwards. so a fan shroud would work well here. Moves the same amount of air as my Cooler Master Blade Master 120, but has more pressure and is quieter

Pros: Initially they seemed like nice fans for a case side panel to blow air into the case using a foam filter on the outside of the case. The idea was to pressurize the case so that the inside of the case had positive pressure wrt the room. I used rubber mounting pins.

Cons: Every so often they would begin to squeal or vibrate and I would take the side panel off remove the fans and clean them. They would be ok for a while and then they would start to vibrate again. This last time I cleaned them and both still vibrate and one of them squeals unless you put it in the horizontal position blowing downward. None of the other case fans have had any problem, just this particular model.

Overall Review: I do not recommend this product and I will not buy the brand again.

Pros: -High Static Pressure -Quiet -Nice looking, in an industrial, understated way.

Cons: -A tad on the expensive side

Overall Review: I've used this non-stop since May, 2017. It is actually paired up as the CPU Cooler fan for the Enermax ETS-T40F-BK. There, in that orientation it has served admirably, providing excellent airflow through the cooler fins with no more noise today than the day I installed it. In that role, I can give this a hearty recommendation!

Pros: Easy to install Rather quite (when they work) Removable fan blade for cleaning (sometimes the cause of excess noise)

Cons: I've had 3 out 6 that I have purchased fail. One was after about 6 months, 2 were less than month old. The cost to return them makes them unlikely to be returned, as you can buy a replace for roughly the same cost. Enermax needs to fix whatever flaw this is with them. They get alittle noisier, then a week or two I could hear the pc from the furthest room away from the living room with the Tv on.

Overall Review: I would not recommend this product until they resolve whatever the issue is. When they work they work great, but they have a unusually high fail rate in my experience. (Not just my pcs but others I know who bought them also.)

Pros: The PWM feature is great, especially when using a PWM controller. The ability to remove the blades and clean them is fantastic! They can be as silent or as loud as necessary and work extremely well with my 2x120 and 3x120 radiators in my custom liquid cooling loop. They do work well with proper maintenance, which I'll explain momentarily.

Cons: They will start to make noise over time. This gives the impression that they are malfunctioning, damaged, or straight out broken.

Overall Review: Due to the nature of the type of bearing and the fact that they have removable blades, I have found that they need periodic oiling. Or rather, I remove the blades, then clean the bearing shaft with a cotton swab and alcohol. After the cleaning, I take a new cotton swab and soak it with oil that I use on hair clippers. This serves me well for months until having to perform this maintenance again. I've had to do this about twice in the year and a half that I've owned them.
