Enermax T.B.Silence Fixed RPM Series 140mm Cooling, UCTB14B

So at the time of purchase this 6 pack was heavily discounted and my gf and I were compiling a list of items to purchase for his/hers pc builds. We had seen reviews of Enermax's AIO and loved their fan design, and came across these. We bought two sets before reading the reviews...and well we were dreading how they would be after seeing so much negativity. I am happy to report that one month in, my set of fans seem to hold up. The colors are nice and vibrant, they stay relatively quiet and are only audible with all 6 kicked to their max speed, but they are not without faults. Some occasionally stop spinning completely and only kick back on when I mess with their speed settings on the included controller. Also their "motherboard" sync option is lackluster. While it responds to Asus Aura, they become very dim, as if they were on their lowest setting. Nothing within Asus Aura makes them any brighter and they only get bright when I set it to be controlled through their control box. Here's hoping that I don't encounter the awful grinding noise so many people seem to get - I really do like the look of these fans.

As others have said, the fans seem fine except the mounting screws don't fit the holes and you basically have to take a drill and enlarge the holes just a bit. The material that the fan frame is made out of is extremely hard. It isn't soft plastic that you can easily force a larger screw into like the plastic most fan frames are made of. You simply cannot force these screws in like you normally can. You just have to use a drill and be careful and not make the holes too big or that obviously won't work either. I got lucky and picked exactly the right drill bit. As far as the fans, they seem to work just fine. I needed an extra fan for the front of my hard drive cage so I just replaced them both with these. They're not silent but they're quiet. Then again the speed is only 900 RPM. You wouldn't expect much noise at that speed. Nevertheless, my hard drives are several degrees cooler and even my processor is running cooler. These are ideal for cooling hard drives. They don't spin any faster than they need to in order to produce enough air to cool a couple of hard drives for each fan. If you space your drives right these fans will blow a fairly wide swath of air. It surprisingly doesn't take a lot of force to cool hard drives. My drives will quickly heat up to about 55 C without any airflow. They stay around 32 C with these fans.

I got these fans for a steal at $6 and was pretty pleased with them at first; however, after a few months, two fan started to rattle really badly. Drove me nuts! I googled for some ideas and came across an idea of adding sewing machine oil to the bearing. Bought some singer oil and sure enough that did the trick! Fans are nice and quiet now. Hopefully, this works for those that had the same issueThe fans come off very easily by pushing the blades off the case from behind. Clean the metal rod, add/spread a few drops of oil, and pop it back on the case.

Pro: Easy to clean, looks amazing, RGB remote, can adjust brightness & fan speed with controller, long (flat) sleeved cables. Powerful and quiet.Con: IR sensor doesnt seem to work behind metal frame of my case. As seen in pictures I have glass panel that allows me to have "line of sight" with the sensor. Control box comes with sticky tape / magnet that are somewhat weak but doable. The adhesive didn't seem strong enough.Other thoughts: I got these fans because of the price and how nice they look. Only was able to use 5/6 fans for my case but it gives it a nice color effect fo display. Cannot get device to sync with MSI. Which is one of the main reason I bought the fans. I have everything connected properly from control box to the 12V RGB header on my mobo.

Fans have good airflow, look great and have a very premium feel to them. I bought 6 and replaced every single fan in my computer. These have proprietary 6 pin connectors and only work with the included controller. This is a problem for me, as i do not have a single fan connected to the motherboard. CPU FAN ERROR makes you enter the bios then exit and boot EVERY time you try to turn the computer on. I have a tower heatsink on my Ryzen 5 1600 @ 3.8ghz with 1.35v (Modest overclock) and these fans in push pull keep it under 70c for the full stress test for over an hour. I love these fans, just wish they would have Incorporated a CPU PWM plug so that you could control the fans through the motherboard and stop if from bugging out on every boot. Otherwise, they are near perfect.

Well these arrived today and I swiftly installed one into my case and one went into my PSU. The PSU is now a lot quieter, no more squeaky fan and the ambient temperature in my case is a lot lower. From about 38*c to about 30*c. I also have another one of these, and a cpu cooler on the way to combine the two. The fan are rather quiet, but spin rather slowly also.Pro's:-Quiet-Cool-Looks-CheapCon's:-Clear wire (I hate clear wire btw)-Silver screws (prefer black to match the case)-Bit slowOverall:Top notch fan, does as a fan should, but slower and more quietly. Ideal for an already cool system that just needs that bit of silence added. I recommend !!

Great

I've not found anything better in that price for years.

I can say no more about this product than has already been said. It is excellent value for money, and the fan fit easily onto my pc machine. I would definitely recommend this product.

Got these as they were on sale but turns out to be very quite and of good quality. Below 1000rpm very quite, above that I dont know yet as my system usually runs below 40 degrees
