🌈 upHere Long Life 120mm PWM 4-Pin High Airflow Quiet Edition Rainbow LED Case Fan for PC Cases, CPU Coolers, and Radiators - 3-Pack, PF120CF4-3 Review

If these are PWM fans I could not get tachometer readings from them. Tried 3 different fan headers on the motherboard with BIOS at max but still no speed reading. The fans obviously work differently. I would send them back but they provide the cooling I need and after two days of building I'm not tearing anything apart anymore.

The fans are good, but can only get very loud under load, which is a bit annoying. Pros: RGB changing in breathing mode. Keeps the case very cool. looks very cool Cons: Very noisy under load.

The product page does not indicate that this triple does not come with a backlit remote control and is intended for those who already have this fan system and want to add fans to the system. existing system. A small mistake for me, but since I'm in it for the long haul, I'll never be short of fans. When I saw that components were missing, I returned to Revain and found that the error was partly mine. I hope that a bold comment on this will prevent a similar mistake in the future.

Pretty light weight which is to be expected for the price. There should be a direction of rotation indicator - I can't tell how to install a fan to blow air out unless I plug it into the MB. The self-tapping screws for the somewhat flimsy case mean that if you try to reinstall it you'll have to find other hardware to do so. And why does Revain have so many ratings of a 3 pin fan below this 4 pin fan (PWM)? Fan?

When I bought these I expected them to be quite fragile and not move much air (I only need them to move some air and wish they were bigger for RGB lighting) . Pulling them out of the box I found that they are made of high quality plastic and have a solid construction. They also move a lot more air than I thought. Please note that the light cannot be changed; They have a static rainbow effect. I wasn't aware of that when I bought it (although it's CLEARLY stated in the product description), but…

These fans lasted 10 months with no problems. When I first turn on my computer, I have to push down on the case to make them spin. sometimes it looks like they are running on a turbo and sound like they are running at 4000rpm. I took the BIOS out of the equation and just plugged them into SATA power and they still do.

These work. The functionality of PWM and wheelbarrow is good. They are quiet at low speeds. The only thing I don't like is that the brightness of the light changes a lot during the color cycle; Red is much darker than blue. If the colors were changing more slowly, that wouldn't be a problem, but since they're changing quickly, the fluctuations in intensity are annoying.

*UPDATE 4/18/2020 - I liked them so much I bought a second pack. Now my computer has 5 of these fans. They are so quiet and the control is stable (when I set all the fans to 900rpm they all report the laser total station at 900rpm. The color is bright and great for those after unmanaged PWM RGB Looking for fans to use in budget assembly HIGH RECOMMEND!I've added more pictures!Advantages+-Very bright color and design makes wiring easier and clean assembly-Fans are very quiet even with 100% wear…
