Review on 🌀 ARCTIC P12 PWM - 120 mm Pressure-Optimised Case Fan with Very Quiet Motor, Computer, Fan Speed: 200-1800 RPM - Black/Black by Mike Marks

I have replaced all my stock fans with these (x3 120mm and x1 140mm). I have a dual 120mm AIO cooler in the front of my case for air intake, another 120mm in the back and a 140mm on top for exhaust. I've used some off the shelf 120mm fans and the included stock AIO fans from my cooler and the temps were fine but the stock fans would spin up to 2000rpm and not push much air due to the amount of noise made out. produced. These new Arctic PWM fans move the same amount of air but are much quieter. Even when they're all blowing at full blast, it's more of a low, low-pitched hum than a loud hum from the fans. I can make it almost silent while running or idling and then auto turn it on when gaming/under load and it's still not nearly as loud as it used to be. I didn't do any serious testing before replacing the fans, but I think I dropped about 5-10C across the board, at idle and at full load. The idle temperature varies between 30-40°C, with maximum load at 70°C. For context, I'm running an overclocked 3900X @ 4.45GHz @ 1.35V. Before that I had around 35-45C at idle and 75C under full load. Overall I would highly recommend these if you want higher temperatures than standard fans and much better sound. At $10 each, you can't go wrong unless you really need RGB fans.
