Works great in my office

These fans work insanely well. Like....holy crap those are fans, well. I wish they had inline switches to run one or both because they are loud but overall I would reccomend.

These are big fans. I did not quite imagine how big they would be. They are in a closet so it is fine. I am very happy with these.

I have been running these non stop for over a year. I wanted to give this type of item plenty of time before I reviewed. The reason I gave four stars is there was a small short in part of the cable. But, price and quality has proven to over come this little issue. They have done the job for 4 years.

Work very well super quiet unfortunately larger than what I was expecting

Professional. Not too loud but there is constant humming with fans on as expected. I used double-sided tape before screwing them into my network rack.

Super high clarity you could buy a separate than adjuster to lower the fans down speed

These move a lot of air and does the job really well.
But they are noisy, was not a problem for me as my server cabinet lives in the basement.

VERDICT: High quality fans for rackmount enclosures. Moves lots of air, moderate amount of noise.

OVERVIEW: I purchased these fans for my Rising Electronics rackmount enclosure: 22U Wall Mount Network Server Cabinet Rack Enclosure Door Lock 600MM Deep. I had emailed Rising Electronics asking about fan sizes for their enclosures and they sent me a link to this product. The product is simple and has a high build quality, but it did take up a decent portion of the top 1U space I had in my 600mm depth rack enclosure. The fans themselves are high quality/thick plastic, and the power cable connector is 3 prongs, 2 of which are split out to the fans, and the grounding wire terminating in a grounding loop that can be attached in order to ground your case.

USE: The fans themselves are moderately loud (about expected to move air in a small enclosure), however this is somewhat reduced when the enclosure is shut. These are 120mm fans that spin quite quickly and move a lot of air - they would be good for any enclosed space where there is a lot of electrical equipment running.

INSTALLATION: Installation is simple and involves attaching 4 screws for each fan to the inside of the case. The cable length is sufficient to reach to the bottom of the rack and contains a grounding loop if you plan on grounding your case.

SUPPORT: I had to contact support 3x during my build process for a number of reasons (general questions mostly), and support was extremely fast to respond to emails. I had to call them at one point with questions regarding one of their sliding racks, and I got through immediately, and they were happy to talk to me and answer all of my questions. 5/5 stars for Rising Electronics as a vendor!

FINAL VERDICT: Highly recommended for any enclosure project, especially in conjunction with a buildout consisting of Raising Electronics server rack enclosures/
