ARCTIC P8 Slim PWM PST - PC Fan, 80mm Case Fan, optimised for Static Pressure, with PST Connection (PWM Sharing Technology), DC Fan, Extra Slim - 15 mm, 300–3000 RPM - Black

Excellent fans that fit great in my micro ITX case. They really move some air and are very quiet. Very thin, but feel very solid and well made. Great price for the quality.

Purchased for use in a Thermaltake Core V1 as exhaust fans. Much thinner than most 80mm fans and great for Mini-ITX setups like mine. The fans themself are quiet but they do move a decent amount of air so you can hear that, but nothing obnoxcious. Male/female plugs on each fan makes daisy chaining easy.

This fan worked better then I expected! I am using this as an exhaust fan for my 2 enterprise HDDs that were running at temps of about 45-47c when Idle with ambient temps in the room of around 80 degrees with the case completely closed up (thermaltake V21).This fan has dropped their idle temps from 45-47c to about 38-39c.As for noise, I am use to fan noise and always can hear the fans in my PCs but I did test it outside the case before actually installing it and with my ear close to it, It was barely audible to me. Inside the case, I can't hear this fan specifically at all because of other case fans I have running that I can hear.The built in daisy chain really came in handy for me because I only have 2 case fan headers on my mother board and have 3 fans in the case already so the built in daisy chain worked perfect for me!As others have mentioned, there are no arrows on the fan like most other fans or any documentation included that indicates what way the air flows but doing a quick google search can remedy that.Or the way I always remember is the side of the fan that forms the support struts for the fan or an X-shape is the exhaust side where the air is pushed out.Everyone is different and everyone has their own expectation and needs but for me, this fan was exactly what I was needing!

Works amazing!!! On my 3d printer . Was looking for a slim fan and I cannot complain !!! Thanks you

it can be a little loud, but it's a pretty good fan. great for the cheaper price too

Perfect for what I needed.Needed a smaller, slimmer fin to fit in my ITX build and these worked like a charm. Really nice fans with great airflow.I ended up 3D printing a couple shields/guards for the fans so that none of my cables got caught in the fan blades.I will be purchasing more of these in the future. Really good.

I needed a replacement fan for a power supply this has worked excellent since I purchased it a couple weeks back. Hopefully it will last a few years. So far so good. I like this brand because you can get information from their web pages. Install and Wiring info. Very helpful. The fan appears to be well made and very quite.

Way too small for good, robust, but quiet air flow. My fault that I didn't more carefully read the description. I find the Corsair 120mm fans more effective.
