AeroCool Shark 120mm Red Cooling Fan EN55437

Fan came in very nice packaging in decent amount of time. My fan is 120 red color was goodand bright. The fan can really move some air useing it as intake fan in front of my NZXT phanthom. It works way better than those factory nzxt fans. Overall excellent fan not noisy at all even atfull load.

Purchased this for extra cooling of my Gaming Desktop. Mounting it in the brackets provided in the Desktop went pretty easy. First used the regular screws but quickly switched to the rubber "screws" provided which were much quieter. These you have to insert and grasp the back end and pull them tightly into the screw hole. Easy to do if there is space but a few were difficult to get into place. Well worth the effort however as the fan runs much quieter with them.

So 26 dB is supposed to be just slightly quieter than a whisper (30 dB I believe) but this thing is definitely noisy when plugged into a molex cable. I suppose the term whisper is subjective even with numbers. The airflow is great but it blows outward, less forward and more radially is the best way to describe it. And since it was mounted on the side panel it wasn't blowing directly on my graphics card. Not wanting to have this fan go to waste I instead moved it to the back as my exhaust fan where it became much quieter thanks to PWM, and moved my Cooler Master 120mm Red LED Case Fan - (R4-L2R-20CR-GP) to the side. The results were better than I could have expected. When playing battlefield 3 for a few hours my temps were very low, my card never getting above 78, and whats more the sound from my computer never changing. Even with the gpu fan going it never got much louder than idle. Using my Sound Meter app, my computer is at 19 dB at idle and I will have to measure it some other time when playing a game though it was quieter than just having this fan on the side panel. I deduct one star not only for the noise (though that's less the card and more not understanding what 26 dB sounds like) and for the not quite forward airflow. As far as the red led. It's red, it's a light, looks nice.EDIT: After playing Battlefield for hours, my video card got to 76 degrees as the max and my CPU temperatures to 45. Other temperatures recorded were 53, 66, and 56 as Temps 0, 1, and 2. I do not have my desktop in what I would consider an open space due to spatial limits. The front fan breathes nicely and I would argue the side fan does as well, the rear exhaust fan, however, is only six inches away from the wall. So to see these temps after playing, and considering the less than adequate position of the desktop, this fan does an outstanding job.

I have to admit that I was attracted by the low price of this bundle, but these are not the cheapest either, having said that the fans were installed as auxiliary ventilation in an already water cooled rig, thanks god they were auxiliary! Because after two weeks of running at less than 25% of its rated RPM one of them started to make weird noises and suddenly stopped, I didn't wait for the other to fail, I replaced it with a Noctua; lesson learned. Doesn't even deserve the star Amazon forced me to give for this review, don't buy this!

Have 3 of these and 3 of their big brothers (140MM Shark fans) and I will be buying 2-3 more of these for my CPU heatsink (big heatsink, fits 3 120MM fans or 3 Phanteks 140MM fans). The LED is bright but not a flashlight and the fans run at a low hum and are working just fine mounted horizontally and vertically in my case!

I wanted great cooling with low noise, and these are a total fail. Sounds like an airplane running in my living room.

AeroCool Shark 120mm Red Cooling Fan EN55437I previously purchased a much cheaper product that was very noisy. I reviewed many reviews that stated these were very good and quiet. I purchased two of these units, but they are as noisy as the products I purchased that are only a 3rd the cost of these. This unit has good air flow and I like the additional blades and the lighting. My concern was due to the noise and therefore, since these are not any quieter, I'm returning them and keeping the cheaper units. I did read some reviews that discussed these make noise if in horizontal position and that is how I have them hanging.

Moves a vast amount of air and the noise does not bother me since these fans keep my PC components running cool for sure! The fan frames are not as rigid as some others that I have used but these fans work as advertised.
