Moustache Boy Posted May 13, 2020 Share Posted May 13, 2020 (edited) Hey guys can you please help me out. My current system is going over 5 years old now, and with new gpu on the horizon I want do a upgrade, and build a system myself. However there are a couple a things I not sure about, and how to do them, how they work etc. So the plan is to buy: a Corsair 500D Case AIO 150 I pro RGB 3080TI :) I want to replace all the fans with QL120 fans. (7x 120mm, 2x 140mm top exhaust) Because I will have 9 fans I be using the Commander pro. But that has only 6 pwm fan connectors. (I think I figured out how the connect 9 rgb) using two led Hubs, connect these 9 to the hub. Connect the two Hubs to a lighting node pro, and connect the L-Pro to the C-Pro I want to setup my AIO As a push pull configuration. So 6x 120mm ql120 fans on my AIO Here's my question. Because of the limited 6 pwm fan connections the CPro, I still need 3 more connection. My idea can I use my AIO Fan splinter? (that are connected to the 150i pro) And connect this fan splitter to my Mobo CPU-FAN connection. Will I then still be able to use Corsair IQEU software to set my fan speed on those particular 3 fans? Or how else can I control then? Is it smart to do so. And which 3 fan's would be best. (sinds I want a push pull configuration.) also I want to front mount my AIO. Hopefully it's al clear, and hope you can help me out here :) Edited May 13, 2020 by Moustache Boy Link to comment Share on other sites More sharing options...
Baio Posted May 14, 2020 Share Posted May 14, 2020 I have a H150i in push/pull configuration and have plugged 6 fans to the AIO's header with Y splitters. Using this connection, I can control all 6 fans speed within iCUE, obviously the software will see them as 3 fans... Y splitters have 2 headers, one with 4 wires and one with 3, the 4 wires header is where I connected the AIO's orginal fan and acts like 'master', the fan plugged into the 3 wires header acts like 'slave', it just behave like the master fan. Be aware when upgrading from LL to QL fans... especially because the 3 packs come with different stuff inside. LL fan packs come with a Lighing Node Pro and a RGB Hub, so probabily in this moment you are just using the hub connected to the LED port of your CoPro. QL packs come with Lighting Node Core, which is substantially a LNP+RGB Hub, but speaking about connections a LNC has a SATA wire and a USB 2.0 wire. So your CoPro's USB ports will be both used by the 2 LNC, and you'll have either to connect the AIO USB plug into your mobo or grab a USB hub. Otherwise QL fans still work with RGB Hub (if you are not planning to sell LL as used), even if there are some limitations on the number of fans the hub will support (I can't answer about this as I'm not using RGB Hubs anymore).

c-attack Posted May 14, 2020 Share Posted May 14, 2020 The H150i should be able to take all 6 fans on its 3 fan channels. You would need to use a 2 way PWM splitter on each of the 3 lines. That leaves your Commander a bit lonely with only 3. It is possible to run them all off one Commander and none of the AIO. It's not what I would normally recommend. You would essentially be re-creating the same set up as above, using a PWM powered fan hub to take the radiator fans. You of course will already have that with the H150i. It's fine to use the QL on the radiator. However, for lighting you are going to want to avoid the Lighting Node Pro. It has limitation with QL fans. You best options are to run the lighting from the RGB channels on the Commander (if you already have RGB Lighting Hubs from another build or fan set) or to use the Lighting Node Core that comes in the multipack of QL. You will need two of those. It is a Lighting Node Pro and RGB Lighting Hub in one package -- but only 1 RGB channel. It connects back to the system via USB 2. The Commander has 2 USB passthrough ports and they can go there. Link to comment Share on other sites More sharing options...
Moustache Boy Posted May 14, 2020 Author Share Posted May 14, 2020 Using 3 Y splitters is indeed a good option. But using that won't that run 6 fans trough 1 cable? Or are you using 2 CPU-FAN connectors on the Mobo? Sorry real noob here Also upgrading from a older pc. Only a Air cooler en no RGB whatsoever Link to comment Share on other sites More sharing options...
c-attack Posted May 14, 2020 Share Posted May 14, 2020 The H150i and most AIO coolers now use a SATA connection for power and do not draw their fan, pump, and lighting current through the motherboard header. That connection reports a pump speed to the BIOS and little more. You will want to buy at least 2 "multi-packs" of 3xQL120 to get the two Lightning Node Core devices you need. The price may not be any different vs buying single QLs anyway. The other option would be to buy 2 RGB Lighting Hubs from Corsair that connect to the Commander via their RGB cables lines (vs USB). The problem with that is they are hard to find and it will surely cost more for those + shipping compared to the multi-packs vs single QLs.

Moustache Boy Posted May 14, 2020 Author Share Posted May 14, 2020 Oké I didn't know that. I though Sata power was just for the pump. And not for everything, good to know. But I think I get it know. Let met just summarize just be sure. I will buy two packs of ql120 (for 6 fans and lightning 2x node core) needs to buy other 2 140mm for top exhaust, and 1 single for back exhaust. I will connect the 6 fans to the radiator. Connect 3 Y splitters. Connect the end cable to CPU-FAN on the Motherboard. Connect USB cable to the AIO and Motherboard.(i believe this is for control) connect Sata power to cpu block and 2x Node core, C-Pro. Connect 9 rgb connects to core. 3 & 6, and connect those two to the Commander Pro. Connect the remaining 3 fans to the C-Pro And ik will have full control? Also the rpm of the radiator and pump? And. I Wil only see 3 fans, because they are split in two with the Y splitter. I believe I can also set a fan curve at a certain degree Celsius. I think that's it. :) Link to comment Share on other sites More sharing options...
c-attack Posted May 14, 2020 Share Posted May 14, 2020 (edited) Yes, you will have full control over all fans. The fans on the splitters will act as pairs, 1 control signal for each pair. There is no reason to run them at different speeds anyway. The pump and radiator fan control will be through the AIO tab in the software. The fan lighting will be through the Core tab. You will have two of those. The software will detect all of the known temp sources and they can be used. However for fan control, you will likely want coolant temp for the AIO and either GPU, coolant temp, or ambient air temp for the exhaust fans. Lots of USB 2 traffic these days. You will need 4. The Commander, H150i, and 2 LNC devices all need a USB 2 port. If the MB has two, then the Commander and H150i each take one, then the LNC devices go into the Commander. If your board only has 1 internal USB 2 hub, you will need a powered USB 2 hub. These are cheap and most any brand should do. For the 140mm size, the "multi-pack" is 2x140. That is another way to get a Lighting Node Core. I have not been watching European prices lately, but the 3x120 multi-packs have been the more economical choice to get the Core vs the 2x140 pack. You'll have to see when it is time to buy. Edited May 14, 2020 by c-attack Link to comment Share on other sites More sharing options...
Moustache Boy Posted May 14, 2020 Author Share Posted May 14, 2020 Oké i got yah. Thank you so much for all this info! I could not figured this out on my own. And these build guides on YouTube, the won't cover information like this. Also thanks for telling me about the 4x usb. Still don't get why motherboards have only 1 or in some cases 2. I could've allready see myself having everything, and coming 1 usb connection short. Thanks again, really appreciate it! :) Link to comment Share on other sites More sharing options...
