Corsair Employee Corsair Notepad Posted May 28, 2019 Corsair Employee Share Posted May 28, 2019 What are you using to monitor and control the fan on the PSU? Link to comment Share on other sites More sharing options...
stevensong Posted May 29, 2019 Author Share Posted May 29, 2019 im using corsair iCUE version 3.15.101 under performance tabs create custom1 profiles and set fixed % to control the fans RPM speed. Im set it to 100% is should spin maximum speed but surprisingly it show 0 RPM . Currently i have another corsair RM1000i PSU and do the same setting it spin as expected.

Corsair Employee Corsair Notepad Posted May 29, 2019 Corsair Employee Share Posted May 29, 2019 How are you connecting the PSU to your system in order to control the fan through iCUE. Also the latest version of iCUE is 3.16.56 Link to comment Share on other sites More sharing options...
stevensong Posted May 31, 2019 Author Share Posted May 31, 2019 (edited) i had update to latest iCUE version 3.16.56 still the same the fans wouldn't spin. Im using USB cable to connecting to motherboard USB header. im even try on notifications tab set ( ( when temp value is ) to value below the PSU temps to trigger the fans spin 100% but also no use it wouldn't spin at all. Does the it something wrong with the PSU? Edited May 31, 2019 by stevensong Link to comment Share on other sites More sharing options...
Corsair Employee Corsair Notepad Posted May 31, 2019 Corsair Employee Share Posted May 31, 2019 So after creating the custom profile to have the fan run at 100% did you ever click on the actual Fan listed there in iCUE. Because in your screenshots where you show the 100% curve the fan is still set to the Default curve not a custom one. With your custom curve selected on the left click on where it says Fan to the right. It will then highlight yellow and instead of it saying Default it will say Custom Curve #1 or what ever your curve is saved as. Link to comment Share on other sites More sharing options...
stevensong Posted June 5, 2019 Author Share Posted June 5, 2019 Yes, i did click you can refer to picture attached. Im even check on the actual fans by reverse the PSU position the fans wouldn't spin no matter what i did even on full load or high temp. Link to comment Share on other sites More sharing options...
Yemble Posted June 6, 2019 Share Posted June 6, 2019 (edited) I have the same PSU and iCUE version. I also have a custom fan curve, but not at 100%, to keep the fan running constantly at at least 700RPM. My PSU fan speed is monitored in AIDA64 and functions perfectly. If this is not working for you, then I would suggest that the fan in your PSU is faulty, although I would try setting a custom curve, rather than 100%, first, before condemning it.

Yemble Posted June 11, 2019 Share Posted June 11, 2019 (edited) I think my PSU fans got problem as didn't have constant spin at all. zero RPM . Should be easy enough to fit a replacement ML-140 fan, if you you don't want to RMA the PSU. Check whether it's 3 or 4 pin and test it in your case (or a different PC) before ordering another. Having Googled this, I think that the correct fan is Corsair NR135P, 12v, 0.22A, 3-pin. If you can't find this, then the Noctua NF-P14 Redux-900 3-pin looks like a good silent alternative, topping out at 900RPM, which is more than sufficient (there is also a 1200RPM version). Pretty cheap on Amazon. Edited June 11, 2019 by Yemble Link to comment Share on other sites More sharing options...

The photo I saw looked like three wires, but I'm happy to be corrected. Do Corsair stock this fan as a spare?

Im even check on the actual fans by reverse the PSU position the fans wouldn't spin no matter what i did even on full load or high temp. Make sure you test this after a full restart or cold boot and not after resuming from sleep. We are seeing an issue with some devices not recovering after a sleep state. What you're describing was happening to me after resume with the fan profile applied in iCUE, but no action. Other PSU monitoring continued as expected. I either need to reconnect the PSU USB or restart. I am sure that will get worked out in the next version, but for now it is a pain. You may very well have a PSU issue, but make sure it is not the software glitch above. Link to comment Share on other sites More sharing options...

Corsair Employee Corsair Kevin Posted June 13, 2019 Corsair Employee Share Posted June 13, 2019 Have you tried running simultaneous benchmarks to ramp up the power consumption of your PC? The screenshots you shared with the custom fan curve setting show that the load at those times were only 82W and 73W. Both the HX850i and RM1000i PSUs have Zero RPM Mode, which means the fan won't spin at all until the load reaches at least 40%. In those screenshots, you're at <10% load. Custom fan curves will not, as far as I know, override Zero RPM mode, and the curve you set is ONLY for loads above 40% of max power output. Here's the HX850i manual which illustrates the fan curves: https://www.corsair.com/corsairmedia/sys_master/productcontent/HXi-Manual.pdf Since you've already tried the fan test function and it spun, that means it works. Fan test isn't supposed to make the fan run at full speed, it's just to check functionality in terms of having power supplied to it and that it can actually spin.

Hi kelvin, thank you for you recommendation and advise yes indeed i run 3D benchmark and try to load the PSU but no matter how i try i can't budge the fans to spin. Or do you have any recommendation freeware / trial software for me to try another round. The reasons i compare with RM1000i is that i understand RM1000i also have ZeroRPM feature but i manage to make it spins under certain circulation. That screenshot is i taken during everything idle time and Im even try to set the temp below the certain to trigger the fans to spin also it wouldn't work but i notice something is that weird when ever i boot up to restart i can see the fans like spark spins meaning it like move abit not even full round 360degree spins. just a jerking spin. Waiting for you to reply. TQ Link to comment Share on other sites More sharing options...
stevensong Posted June 13, 2019 Author Share Posted June 13, 2019 From my observation it might not due to the fans problem as fans test the fans was pass it will spins during the test ... as it might be the electronics circuity board that control the fans that have problems.

Corsair Employee Corsair Kevin Posted June 13, 2019 Corsair Employee Share Posted June 13, 2019 Hi Steven, if you've already tried everything and even at a >40% load, the fan doesn't turn on, I would suggest starting a support ticket at http://www.corsair.com/support. There, they can guide you further, whether helping you with that unit or setting up an RMA. I'm sorry for the inconvenience! Link to comment Share on other sites More sharing options...
Corsair Employee Corsair Kevin Posted June 14, 2019 Corsair Employee Share Posted June 14, 2019 Hi Steven, I was informed that setting a custom fan curve in iCUE SHOULD override Zero RPM mode. Sorry about that. There was a bit of a misunderstanding when I inquired about it earlier. In any case, it does seem like you just need to RMA your unit. If we can be of any further help, please don't hesitate to ask/inquire. Link to comment Share on other sites More sharing options...
Pocah Posted June 19, 2019 Share Posted June 19, 2019 When you set the notification, you have to click on the temp above to apply that notification. If you don't, nothing happens. The moment you apply the notification, everything will turn red and the fan will go to 100% Link to comment Share on other sites More sharing options...
