You need to have a four pin header and thermal PCM fan controller on MB or external unit. This fan moves an insane amount of air at 3,000 RPM! It crated so much static pressure that it made an unplugged identical fan next to it spin so fast that I thought it was plugged in before I did so. The noise curve is quiet and almost identical to the 2,000 RPM version and don't get loud enough to hear more than 3 ft away from PC until you get right at about 2,000 RPM. At 1,700 RPM, it is no louder than a CPU or graphic card fan at slow speed. Having the insurance of extra speed available if needed (A/C fail) or other case fan fail makes it well worth the extra cost. I plan to use this fan exclusively for all my cooling needs. You can't go wrong putting these on a radiator for a CPU/GPU cooling loop. Read full review

product works fine but was supposed to be open box but both fans had dust on them so they were used.

The industrial Noctua fans “can” be really loud if you need to move a lot of air… but you can move A LOT of air. Perfect for my 60 mm radiators. I believe they may be a bit louder at the same rpm than standard Noctuas but you have 1000 rpm overhead over standard. I never really hear them anyway unless I’m benchmarking. Plus these are water resistant.

When you care more about total system cooling and less about noise, these are the fans you want. I have an NZXT H7 Flow with seven of these bad boys installed, and at 50% speed, my temps on my CPU (Ryzen 9 5900X) and GPU (Radeon RX 6900XT) never go above 65c.

This are literally the best fans you can buy, quality and performance, a little loud at full speed but not so loud that is bothersome. Noctua has a customer in me for ever. 👍👍👍👍
