ARCTIC BioniX P120-120mm Silent Cooling Fan for CPU, PST Control Function, High Static Pressure, 200 to 2100 RPM – Grey

Using two of these to replace a pair of Fractal Design 140mm fans in a Define 7. The Fractals were whisper-quiet, but summers here are boiling hot. These do the job well and push tons of air, with a significant noise penalty at high output. Some specific PWM tuning is needed to optimise performance to noise ratio for your needs.There's no motor hum or vibration - the chassis is hefty and reassuring and most of the noise is from airflow and turbulence, rather than motor and frame. The cable is braided and comes with a PWM chaining socket so you can run multiples off the same header. I would recommend this in a heartbeat.

Working as expected , low on noise, powerful airflow

Bit noisy in higher rpm but it's very powerful 140 mm fan, thank you

Now before people go complaining about how loud it can get under full load understand its a static pressure fan. By design at full speed they will be loud, any company you take.What is a static pressure fan: Its forces air inside your cabinet like a jet engine, concentrated jet, cylindrical fashion. Normal fans are like your home ceiling fans which throw air all around the place.So how is this useful: Its useful to force more air into the system and maintain high pressure where the heat from the system and can absorbed by the air. So its not just best but you need to put these as intake fans. If you put these as exhaust/outtake fans (any place, back or top) more air will be thrown out of the system than going in, essentially leading to negative pressure, meaning there will be lesser air than normal for heat in the system to be transferred to.How good is this particular one: Specs you can read. The fan itself is pretty good, performance wise and looks wise. It gets loud but better than Silverstone Air Penetrator. If you are having air cooling on CPU, you can see temperature decrease after installing these as intake fans.What needs to be improved: The screws provided are like as if they have no head on top. Also no washers are provided (which should be at this price point) and it scratched the paint on my TD 500 Mesh white.NO RGB, but I don't care, so no issue for me. I wanted white color to suit my case but are not available anywhere so had to do with red color.Overall, good performance wise, aesthetics wise good enough if you don' care about RGB. 4/5 because of screws.

efficient, almost noise less fan !

It's a nice case fan overall. loved the product, great airflow. The only problem i faced was that the cable was too short limiting the no. Of ways u can route that or u can just get an extention cable

I buy Arctic Bionix P120 fan from seller. The product not working after 20 days.I many time tried and requested to seller to replace faulty product but no response received.I wasted my money on product. Amazon or seller not provided warranty replacement to me.

Installs like any other fan but the fan frame is flexible. So, you should use a screwdriver to spin the blade after you install it, to make sure you didn't warp the frame and the fan blade is now touching the frame. It moves allot of air at lower noise levels than other fans. It's slightly thicker than standard fans so you'll need a little extra room for it. It's 28mm vs. 25mm thick. The only con is, it costs more than other Arctic fans.

Great fans. PWM fans is the way to go.Great static pressure and very low noise. Better than even Noctua fans.

I am using these fans on a artic cooler and love the aesthetic. Noise noise about the same as any other fan and haven't had any issue with temperatures.

Very good price and importantly better quality

perche sono piu silenziose
