Bgearsb-Blaster 90mm 2 Ball Bearing High Speed Extreme Airflow Fan Black

For those saying this fan is fairly loud, you're correct. I have this fan wired directly to my EVGA power supply, so it is spinning at it's max RPM. It is quite noisy, however very functional. To compare, I have a second computer housed in an Antec 900, which has 2 front intake fans, a large top exhaust fan, a rear exhaust fan, and a side intake fan. The Bgears b-Blaster 90mm is still louder by itself than my entire Antec case is. HOWEVER, this fan pushes a considerable larger amount of air. I have a Dell Optiplex 7010 MT (not the small form factor) that I have re-purposed into a gaming PC. I modded the front of the case so that this fan could sit nicely as an intake fan, combining with a Zalman CPU cooler. Since adding this fan, my CPU temps dropped about 4 degrees C overall, so this fan is making quite a bit of difference. The Dell case that this computer is in is quite a joke for airflow, but considering how cheap this fan was, and how easy it is to cut some holes behind the front panel grill, it is quite a decent machine now.I would definitely recommend this fan if you are solely looking for airflow. If you are looking for a combination of quiet and efficient, you may want to consider a different fan, or attaching this fan to a controller or motherboard that will allow you to control the speed.

If this fan is installed with the blades passing close to a perforated surface, the fan will be noisy because the surface causes the airflow to be interrupted as the blades pass by. Actually, this is how a siren is constructed. If the blades are at least 1/8" from the surface the noise is significantly reduced. In my case, I mounted the fan on the other side of the surface. Of course, the noise would be greatly reduced if the fan blows through a clear opening.I mounted it in the front of a case to blow on the hard drives of a server to extend their life, and it worked well for that. But, because it moves a lot of air, it is not a silent fan.

This little fan is a workhorse.It's not pretty, it doesn't have bells and whistles, it's not the quietest, but it gets the job done well.I replaced my case fan with this fan and I objectively noticed my CPU temps going down by 5°C on average.Don't listen to the noise complaints. Yes, it will sound like a small vacuum cleaner when plugged in directly to the Molex cable. However, when plugged in to the 3 pin header on my motherboard, and having my CPU run at 100% load for hours at a time, the noise is low enough that it gets drowned by the sound of my ceiling fan.I'm very happy with this fan.

Yeah it really is too loud to enjoy your computer lol. It sounds like a room fan on high setting.Get a fan that can connect to a 3/4 pin connection on the motherboard. Not molex. Molex is connected directly to the power supply and doesn't allow the fan to communicate with the computer. The motherboard regulates fan speeds to reasonable numbers. When you plug a fan into a PSU directly, the fan automatically is just powered to full RPM. This fan would be good for a server computer that is left alone. The cooling is absolutely phenomenal. My CPU stays at 125 F even under a huge load.Instead of this ball blaster right here, spend the extra 7 bucks and buy a fan that will last, can be controlled through the motherboard and won't be loud as hell:https://www.amazon.com/gp/product/B00NEMG9B0/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

For the amount of air these things push, they're very quiet. And do they ever push air... this fan will outperform even some 140 mm fans. The noise emitted from the fans is a fairly low pitch, which is much more pleasing to the ears then a lot of other fans this size that have a high-pitched whine. I'm using these poor ventilation in a server rack and they do an incredible job of supplying are for all of my servers

Gave this 5-star ratings in every category, although I first had 4/5 stars highlighted for noise, because it is a bit noisy, but all super high-performance fans do, so I changed it to 5/5.Fan is VERY powerful and can move LOTS of air in no time! I also run my fans 24/7/365, at ~85% maximum power (fan speed/power turned down using voltage controllers).I love all my Bgears fans, and they have been my primary "go-to" brand for years!

Reemplace los ventiladores originales, sonaban como un tractor, por estos. Fantástico.Ahora calienta más rápido.A*****

This will be short. I bought this to replace a case fan which went out. I installed it, and the fan didnt act as it should. I went into BIOS to see if I needed to make a change- which I did not. I then installed a second fan and had no issues. The fan was DOA out of the box. Maybe others have had better luck. I might try this brand another time and if I do- I will update this thread.

This material is the worst I ever hadThe wires bread down just trying to connect them !Not as pictured... the wired shown in the pictures are not factual... it is cheap thin transparent wires, extremely fragile.terminal are not isolated properly or barely...Never had the chance to had it working, the wires breakdown in my hand while trying to connect them...Is that cheap... yes !!

Very strong airflow. The only drawback is it's quite noisy. If that is not a concern for you than this is a great fan.

Great airflow my computer is so cool it never had a intake. I also replaced my rear exhaust fan.... I think have both fans is very loud but I am alright with it considering the cool air that was hot before

Make sure you tie down whatever you're mounting these on, because it will fly away.
