Philipyeung Posted July 24, 2020 Share Posted July 24, 2020 Hi, I currently using 10 X QL120 fans to set up my new pc, and I am running it with 2x lighting node pro, 2X PWM hubs (OTOTEC 10 portshttps://www.amazon.co.uk/gp/product/B07S89LLZZ/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 and 1 commando pro. for all ARGBs lighting setting, it works fine under iCue. For fan control setting. I am having a problem seeing all 10 fans. I have plugin port 1,2,3 & 6 for my 3 side intake fans and 1 rear exhaust fan. these fans are working perfectly and I can see them through iCue. However, The top rads x 3fans and bot rads X 3 fans are plugs into the 2 PWM hubs. which are not detecting in iCue. I am not sure if this is hardware problem or a software problem. if someone can advise that will be much appreciated. Regards Phil Link to comment Share on other sites More sharing options...
c-attack Posted July 24, 2020 Share Posted July 24, 2020 Try manually setting ports 4 & 5 for the PWM hubs to "4 pin" in the Commander Pro settings. Sometimes the auto doesn't read it correctly. Link to comment Share on other sites More sharing options...
Philipyeung Posted July 24, 2020 Author Share Posted July 24, 2020 Thanks for your help. I have tried to change the setting from Auto to 4pin in the commando pro. However, the fan control page still showing 0 RPM and will not make any different if I change to quiet or extreme. However, what I have noticed, is when I switch between the auto and 4 pin. the fan speed changed. I guess is doing something, but not quite right. Hope someone can help. Just don't want to buy a new commando pro or new hub incase is just a software or setting issue. regards Phil Link to comment Share on other sites More sharing options...
LeDoyen Posted July 24, 2020 Share Posted July 24, 2020 Are the fans spinning though? These hubs only have one plug that give the speed reading back to the Commander Pro. If you have no fans connected to the red plug, you won't see any speed reading at all. Link to comment Share on other sites More sharing options...
Philipyeung Posted July 24, 2020 Author Share Posted July 24, 2020 thanks. I did what you sugguest and moved one fan header to the red connection on one of the hub. It detected the fan speed now, you can set the speed in iCue but it does not change anything. :bigeyes: Link to comment Share on other sites More sharing options...
c-attack Posted July 24, 2020 Share Posted July 24, 2020 (edited) Make sure you are not using the three Commander fan presets (Quiet/Balanced/Extreme) to test this stuff. It is a hidden and mysterious curve linked to CPU temp and you are likely to see 1400 rpm all the time. I recommend everyone get off those immediately. For actual control, use your GPU or MB temps for a quick set-up. Long term the temp probes or your water sensors are the ideal control sensor choice. For now, just create a new custom curve and use the fixed RPM or Fixed % to deliberately move the fan up or down so you can test compliance. That said, there also is the possibility the Commander just doesn't like the PWM signal for the device. There have been some issues with compatibility and there seems to be some differences in PWM spec between regional areas. Some of the Noctua, EK Vardar, and BeQuiet fans don't always respond to the Commander's signal. I don't think we have a list going for PWM hubs as to what works and what does not. I know some use an obscure part from a Corsair case that essentially identical to what you have. I am using a Silverstone 8 fan PWM hub and it works great, including smoothing over some of those troublesome fans that don't work when connected directly. I have seen this hub online, but don't know anyone with first hand experience with it.

Philipyeung Posted July 24, 2020 Author Share Posted July 24, 2020 thanks, I did try to set the fan to stop and max on % and it result the same. But thanks for the tips. I will see if I shall buy a silverstone and have a go at it. Link to comment Share on other sites More sharing options...
Philipyeung Posted July 24, 2020 Author Share Posted July 24, 2020 currently, I am running 2 PWM hubs on 2 commando ports. Do you recommend 1 Silverstone 8 port is enough on 1 commando port, to do what I am doing here? Link to comment Share on other sites More sharing options...
c-attack Posted July 24, 2020 Share Posted July 24, 2020 It can handle the current. I have run 6 industrial fans off it for the side rad. 6-8 QL should not be an issue. Of course, they will all run the same speed so this is best for offloading a pair of 3x120 radiators. I think there is also 6 or 10 fan hub.

Philipyeung Posted July 24, 2020 Author Share Posted July 24, 2020 By the way, i manage to sort it out, and don't need to replace my hub. Thanks a million C-attack you are amazing! It work when I play around with customer graphic setting! Link to comment Share on other sites More sharing options...
LeDoyen Posted July 24, 2020 Share Posted July 24, 2020 Yup, those default fan curves are.. a nightmare ^^ Link to comment Share on other sites More sharing options...

It work when I play around with customer graphic setting! I'm glad to hear that. So far everyone has been having success with the PWM hubs. I am hoping that continues and it seems to be an effective solution. I like it better than running two Commander like I was before. Link to comment Share on other sites More sharing options...
