amadeus1171 Posted June 1, 2019 Share Posted June 1, 2019 Does anyone know why my fans don't spin at the same speed? I'm using the Commander Pro. All six fans are Noctua 4-pin. The Commander Pro fan settings are all 4-pin. And they all share the same performance setting, Extreme. Can't the Commander pro provide enough power to spin all fans full speed? See image for fan speeds at Extreme. Fan Speeds Image Link to comment Share on other sites More sharing options...
c-attack Posted June 1, 2019 Share Posted June 1, 2019 Noctua 4 pin what? Since you are a measurable amount over 2000 rpm, I have fairly good guess, but in this instance you need to be clear. Link to comment Share on other sites More sharing options...
tiessar Posted June 1, 2019 Share Posted June 1, 2019 Seems like you have two different types of fans. Link to comment Share on other sites More sharing options...
amadeus1171 Posted June 1, 2019 Author Share Posted June 1, 2019 Fans 1,2,3 are Noctua NF-A12x25 PWM, Premium Quiet Fan, 4-Pin Fans 4,5,6 are Noctua NF-F12 PWM, 4-Pin Premium Quiet Fan Yes, they are different fans. But get this: fans 1 and 2 are the same fans set on the performance profile (CPU-not in the image shown). Fan 1 will spin near or over 2k rpm while fan 2 will be stuck at something like 1200 to 1300 rpm. I'll try and get a picture of this happening.

amadeus1171 Posted June 2, 2019 Author Share Posted June 2, 2019 I think I figured it out. It was the max fan speed. I just assumed the Noctua fans would go faster than what they can accomplish. Instead, they wig out when you set a value out of bounds from their specifications. Thus I kept getting weird fan speeds. I set the max fan speeds properly now, 2000 for fans 1-3 and 1500 for fans 4-6, and they appear to be functioning within specifications. This leads to a suggestion for a change in iCue, specifically, the fan settings for the fan pins in Commander Pro. Include setting for fan low and high to prevent the user from over or undersetting fan speeds, and/or include a list of popular fans from a drop down so these settings can be set automatically instead of manually.

You can set your fan speed to anything you want, within the operating range of your fan. However, it is up to the user to know what they are plugging in.

amadeus1171 Posted June 3, 2019 Author Share Posted June 3, 2019 That's my point. Give the user the option to set min/max speeds for fans. Over time you forget what you put in. I assumed the fans would know to stop at their max speeds, not have a conniption. lol And it doesn't help that my custom fan curses keep getting erased periodically, for some reason. x.x Link to comment Share on other sites More sharing options...
DevBiker Posted June 3, 2019 Share Posted June 3, 2019 The fans won't go any faster than their motor allows them to go. Period. As for the fan curves - this is a known issue and a painful one. Look in the release notes for 3.16 for a workaround. Link to comment Share on other sites More sharing options...
