EZDIY-FAB 12cm 120mm 200CFM 4000RPM CPU Cooling Fan 12V DC 4-Pin Molex PC Computer High CFM Cooling Case Fan with Metal Finger Guard Grill

Pros:-No rattling-High flow rate-Heavy duty, really well made-Efficient running wattageCons:-No easy way to control RPM (molex)-Quite a bit larger than normal 120mm fans (sometimes hard to install depending on space)You will not want to buy these if you are looking for extra cooling fans for a gaming computer or regular workstation. These are extremely high RPM (which makes them extremely loud). High quality molex fans like these are perfect for my servers and mining rig operations at home. If you are looking for something that will continuously operate 24/7 reliably and safely, I would recommend these.

It moves a lot of air but they are straight out lying about the 59db unless they mean just the noise of the fan spinning. It's molex, so without an adapter/controller it's either on or off.To handle the noise issue I ended up having to put them on the bottom of my case exhausting down. Still moves a lot of air and makes less noise. Less. I installed a switch that I leave off except when gaming because people can very clearly hear it through my desk phone and there's no way I could sleep in a room with things going full tilt.But I have an MSI video card so I'll deal with the noise if it will push off the inevitable RMA.

They are noisy but they seem durable and blow quite fast. They also make this weird buzzing sound and for one of them when spinning too fast it starts making very strong vibrations and shaking the table. I guess that's part of the deal though.Edit: The seller reached out to me and offered me a replacement for the shaky fan. Excellent customer service, excellent product, excellent price!

Not sure whether to give these a three or four star rating. They move the air, but they are LOUD. With two of them in the same box at one end of our kitchen, you really had to raise your voice to be heard over the noise. I decided on four stars because they do move air and any 400 cfm installation might be just as noisy.

4/9/24Finally had to remove one fan due to failure. It was the loudest one and it finally just stopped moving.Edited 12/16/23Going to revise this as the one that had a slight vibration is now extremely loud and shakes the whole PC. It sounds like it’s going to blow apart at any second.OG review:These are apparently server fans that I am using in my PC case for maximum air flow.This works for me because I have my PC in my basement and have all my cables routed up through the walls to my TV upstairs. So fan noise is no issue. Can’t hear a thing. However I would not recommend these fans for that purpose if you have your PC right next to you. These fans are extremely loud to the point of absurdity. They do however move a ton of air which is what I wanted.I read many people getting gpu temps of 75-85C on 7900xt. Mine can’t break 60C at full load gaming. The same is true for my 5950x. Most people see temps around 75-90C, and mine never goes above 65C with a tower cooler and these fans.Last note is that one of mine has a slight vibration which is annoying and I wonder if it will affect the life of the fan. Another is that they seem to be made of brittle plastic so whatever you do don’t let anything touch the blades while running. Fortunately they have grills included.

+Performance is crazy these move so much air.+Improved my hashrate about 20% after it took a dive due to summer heat.Cons are acceptable just a heads up-bigger and harder to install I had to rearrange my gpu so the longer ones were in the middle and not on the outer sides to get these to fit in my frame.-LOUD, I have these in a shop very loud between vacuume cleaner and almost lawn mower level. If I planned on working in the shop i would put these on a controller and dial it down while I'm in there.

BOTH of these fans move a high amount of air which is good, but they are both MECHANICALLY NOISY... and I don't mean the wind or fan noise you would usually be familiar with.... which that part actually isn't too bad at all. What I am hearing from one of the fans is a bearing that squeals something horrible! The other one rattles like there is a loose wire hitting the fan blades. I just got these yesterday, if they don't break themselves first, rather than break themselves in, they're going back.UPDATE: Only few hours after posting this the squealy fan just stopped its mouse-like noises and went to a violent shuddering which shakes my whole computer rack... it sounds like a small engine running in my server room and can be heard over everything else. The other fan is still sounds like it has something stuck in it, but there is no obstructions.

Man do these fans blow (or suck, depending on how they're oriented). I purchased 2 units without the disco lights, so this review is for the fans only. One used in an enclosure to move excess heat from my home server to the outdoors. The other is on a speed controller and pulls air through my workstation case. They are well built, solid, move a lot of air, and have minimal vibration once properly mounted.Now, these guys are a little loud at full power - louder than a standard PC fan, but certainly not as loud as say, a hairdryer. But at this price and size, you're not going to move a lot of air without a some noise. Nonetheless, I'm totally satisfied.

Used for moving air over a camper trailer fridge compressor. We travel in the outback of Australia and the fridge struggled with the temperatures. The fans work very well.

Muy potentes pero es una turbina. Son ruidosos. Válidos para sala de servidores y mineria

Je l'ai attaché a l'entrée d'air de mon poele, puis j'ai fait un bouton Home Assistant qui le lance pour 30 secondes lorsque je l'allume. Ca marche super bien.

Ventole molto potenti, che soffiano circa 4 volte più forte delle classiche ventole da Case PC.Sono pero molto rumorose, e sono anche troppo potenti per un utilizzo Home.Io le ho montate in un server, accese h24, e non danno il minimo problema.

Queste ventole sono un tornado di grado 5!Spaventoso lo spostamento d'aria che movimentano. Il rumore però è da classica ventola server: rumorosa!
