Pyle 19” Rack-Mount Equipment Cooling Fans - 110V/60Hz Power, 4 Cooler Master 80mm Case Fans, Smart Cooling System, Digital LCD Temperature Display & Installation Hardware Screw Included -PFN41

One fan got a little noisy and i tapped it with my fingers and it stopped being noisy, I installed this fan into my stereo cabinet. the temp gauge works great also.

DO NOT PURCHASE....THIS IS JUNK My original 5 star review has now been lowered to 1 star because you are not allowed to give Zero star reviews. The product looked great and worked fine for a few months but then 1 fan went out while the other fan started making horrible noise requiring me to shutoff the unit. I contacted thier support which replied after 4-5 days informing me that I had to pay to ship back and they would repair and ship back within 6-8 weeks. I've been in IT for over 30 years and most companies would ship out a replacement and as for a return on their dime and would complete the process within a few days. With a 6 to 8 week turn around they must be sending back to China for the repair. Please read all the 1 star comments which will give you an idea on why so many units are failing and to stay away for this product. I considered having the unit repaired until I read the other reviews and decided I would be wasting my money because the new unit is probably going to fail and the wasted money on shipping could be applied to a better product. Also, the temperature reading is not accurate as others have stated. -- Original Review Below but please don't use for your eveluation -- This 4 fan 19" network rack cooling master with LED display adds cooling with a touch of pizazz. I tried another brand with the exact same look and functionality but experienced 2 defective units leading me to discover this version by Pyle. It is a very solid and mounts easily into any standard 19" rack. The 4 fans really push air but are not very loud. The LED display is bright with accurate reading. The price is really good so you get a big bang for your buck. I would purchase again.

Well-made, easily installed, and hook-up. Does the job well despite being a little noisy. It would be nice if they were two-speed.

Bought this fan for a rack case with three power amps for running studio sound boards. Been working perfectly, very little noise and keeps the rack cool.

Let's set aside the poor delivery condition where 3 out of 4 corners were completely mangled and bent, paint chipped etc, and one of the fan casing had an entire corner cracked off. The middle left fan was completely inoperable and DOA. Let's focus on part that was 100% within Pyle's control... the temp sensor on back seems more like a button. It was not seated correctly and I couldn't tell if it was reading proper temp. I tested it along side two other sensors and the reading, at floor was ~5º off. The unit being 2.5u is sort of annoying for full server cabinet when mostly everything is 1u increments, I suppose for audio AV rack less space the better, but not in my case. The blue sticker film on the fans is ugly. Total eyesore. I don't need the PYLE logo to be so prominent or the model number. It's ugly and unattractive to have it so proud and the hero of the system. No on off switch but not end of world if with a PDU switch board. I replaced it for a 3u Navepoint system running 3 fans. Seems to be a better built system.

Well worth the money all metal no plastic each fan ball bearings very powerful they are not that quite because they are powerful but if you want effectiveness that is something we can all live with for four fans they aren’t that bad

You get the impression that you are purchasing a professional grade cooling fan system. You are not! The device is a cheap knock off.... the cooling fan's bearings seem to burn up any lubricant that may have been installed and they quickly overheat and stop spinning causing excessive heat in the motors..... somewhat defeating the intent of moving the rack unit's heat.... they create heat. Unfortunately, parts are not easily accessible to make repairs, there is no support or implied warranty that will take care of fans which fail in operation. If you mount the unit in a horizontal position with fans blowing up or down it seems to work best as opposed to blowing in or out. I would suggest spending the additional money and buying a different suppliers unit. Although the unit has a nice appearance it's functionality is limited in that it fails very quickly! My fear is that unattended the overheating motors could cause a fire if not caught in advance when the fans stop spinning...

Looks like a nice product but the fans were a bit noisy but the rack mount was bent and QA did not catch it. No temp control . Nice display but without actually setting when fans turn off and on. Really regret buying it. Oh i forgot to mention that I got a used rack fan not a new one. This is typical of these cheap ass companies trying to pass off used damaged goods for new. geez I guess amazon needs to start getting on these folks for items advertised as new but is pretty clear that is was returned and tried to pass off to the next guy. Very poor and typical on Amazon goods these days. Its made by Plyle and might not be makers fault just the folks trying to pull a fast one on damaged and second hand goods. I guess knowly and willingly to do so might be considered fraud.

Great produc . I loved . Works super cool.

Buen producto la relación costo producto supero mi espectativa 👌

This is being sold on Amazon uk. IT IS 110VOLTS AND CAN NOT BE USED IN THE UK WTF!!!

This is by far one of the worst products I have ever ordered from Amazon. When I first installed the fans, they produced a foul stench of what I can only assume is the oil in the fans. I though that oil smell would dissipate after running for a few hours, but the smell never goes away. Also, the fans actually seem to be of no use at all in cooling my server rack, despite being at the top and back of the rack, with no air flow obstruction. When I las turned the fans on, the temperature in the rack started at 114F and then quickly rose to 117F, with no subsequent cooling until I turned the fans off. The display often shows invalid characters, at one point I believe it was attempting to display 119F, but the second 1 was display as some kind of backwards 2. Speaking of Fahrenheit, there is no option to switch the display to display Celsius readings. I recently purchased intake and extraction rack mounted fans for my rack and they are a far superior product. I will avoid anything made by Pyle in the future like the plague and recommend that everybody else does too. This is a garbage products - avoid!

El problema es que llegó muy sucio, no se si por uso o condiciones de almacenamiento. Los ventiladores son en extremo ruidosos. Dicho esto, cumple con el objetivo de enfriar el rack
