tyrindor Posted January 11, 2017 Author Share Posted January 11, 2017 Anyone interested in results? The Noctua P12s at full speed resulted in 45-50C during parity checks. The new Noctua NF-F12-iPPC-3000s PWM were set to 30C (low) and 40c (high) with autofan. I'm currently 7% into parity check and they are at 74% (2146RPM), and the hottest drive is 36C. Most are 33C. When the drives are below the low temp value, they spin down to a whopping 277RPM. This is crazy because they are only suppose to go down to 800RPM before turning off, they produce no noise at these speeds. I may tone my fan settings down because 36C is still pretty cold. Even at 74%, they are significantly louder than my P12s at full speed. At 50%, they are slightly quieter than the P12 but spinning about 400RPM faster. However, they seem to suck through the bays significantly better and will likely keep the drives <40C at those speeds. So the result is a quieter AND colder server. I still haven't sealed up many of the openings, which should help even more. Link to comment
garycase Posted January 11, 2017 Share Posted January 11, 2017 Not really surprised ... as I noted earlier "... with that much increase in static pressure there simply has to be a big gain in cooling efficiency. " I AM somewhat surprised at just how much better it is, however -- I figured at least a 5 degree drop; and yet you're getting well over 10 degrees !! ... and that's not even at full speed. Clearly this was absolutely worth it !! Link to comment
garycase Posted January 11, 2017 Share Posted January 11, 2017 ... and what's REALLY neat is that UnRAID already has the plugin you need to fully automate the fan speeds. Link to comment

Clearly this was absolutely worth it !! 14% in and still under 40C, with only 62%. About the same DB level as my P12s at these speeds. Definitely worth the $75. Link to comment
ldrax Posted October 12, 2018 Share Posted October 12, 2018 Not trying to wake up an old thread, but I was inspired by this thread and got a 1x140 (intake) and 1x120(exhaust) of the said noctua ippc 3000rpm, and in general they bring down the temperature of my 6x7200rpm drives by 9-11 degree during parity check, with both fans controlled by Asus motherboard Q-fan thingy (silent mode), so far it spins the fans max at +- 2000rpm, and yeah the noise not ideal but I can live with it for now.

garycase Posted October 22, 2018 Share Posted October 22, 2018 Glad the thread helped -- some of these topics can get "buried" and folks with the same issue may not ever see them. An occasional post that highlights that the info is still relevant isn't a bad thing at all. Link to comment
