These fans are perfect! They are quiet, easy to control and really push the air. I've bought from other companies, but GDSTIME is always quality. I only expected grills on one side, but they are on both, so bonus!

Moves a lot of air, not much vibration, and it's actually pretty silent at the moderate to half speeds. I'm currently using this to cool a bunch of small desktop switches in a vertical stack that I use on my server set up. It's cooling a major hub in my home lab that constantly routes blue Iris ONVIF streams from wireless cameras. So they're always working (24/7) harder than they were intended. The extra cooling just provides peace of mind. This fan stand is actually a lot more powerful than you'll probably ever need, so it's a good thing the onboard controller can take it very low. But it's well balanced and I thought it was put together pretty well. I don't have any odd vibrations and it's been running consistently for about eight months now and has not developed any noise/grinding. The extra length is really good for longer items like 16 port desktop switches and things like that. Honestly for the price I thought it was a fantastic deal, I may repurpose it for something later, and the truth is is you can easily disassemble it and swap a similar fan and if you really needed to. As long as the controller keeps working the items lifespan is really indeterminate. You could essentially keep replacing fans as long as the controller works. So far I recommend this product, it's been nearly a year and zero issues or irritating noises. I run at about 40% of its maximum speed, according to the dial on the controller.

They work as fans but I was hoping they'd pull a bit more air especially for how much noise they put out twords max power. I got them as puller exaust for exterior cooling but I'm thinking about splitting them for intake inside the pc and exaust inside the pc. They'll probably work for you with some experimenting. If you don't care though remove the side of your pc case and replace the side with a box fan blowing into the case. That was the best cooling I ever had but I blew my gpu in about 9 seconds after it fell one day and I was mid fight in fallout 4.

Worked less than a year. All four fans locked up. Rheostat gets red hot at max setting Money back or replacement would be great….

Cannot easily separate so plan on using both in one place. Pretty quiet at low speed but mount with rubber grommets to stop most vibrations.

These work great. My PC case was running hot with the stock fans installed. I swapped them out with these and now it runs consistently 50-70 degrees Celsius even under heavy gaming. Noise level can be controlled when you select the speed. I usually turn the fans up higher when gaming then down to low when I'm just watching YouTube or Netflix. Best value I've seen on these so far. I even bought a spare pair.
