I have three roof fans mounted for top exhaust and I plug those into the builtin fan_hub using the PWM (4pin) connectors and then connect the 4 pin PWM lead from the Fan hub to a CHA_fan header. The last thing to note about fans is to avoid using fan headers that are labeled “W_PUMP”, “H_AMP”, or M.2_FAN.” These are meant to power different kinds of fans … You'll then just tailor the fan curves to what output expectations you have. Is it better to get a fan hub? As a follow up question, where did connect rad fans? If you’re passionate about learning all you can about engineering, and I’m pretty sure you are, ... We know the pumps need to push water through the chiller, so we can connect the pump sets to the chillers evaporator inlets. Would this cause any issues with being able to control the RPM of the pump or fans? It works (by default) as a PWM fan header. Otherwise, the pump won't get the full 12V that it needs. Cheers, I was planning to have nothing plugged into the CPU header as the radiator fans are connected to the water pump. Chilled water is generated in the evaporator so we’ll need to connect that back around to the pumps to create a circuit and distribute the chilled water. ThrashZone. Directly to Corsair pump cables or did you utilize other MB Headers? That way I can control all three fans (as one, not individually) from the same header using Qfan or FanXpert. System works flawlessly on the Maximus Hero XI. Your motherboard has a header for PUMP and CPU FAN / CPU OPT. Ok thanks, I found an adapter to hook up fans to my PSU. Pin 4 has a 5V 25 kHz PWM signal that tells the fan how fast to spin. And … One must not forget that fan noise is NOT just the noise made by the fan motor. Fan has a 4-pin power connector; desktop board has a 3-pin fan header: References . Win10 Pro 64bit . Posts : 95. And for completeness: With four pin headers, the 12V is constant.

I found a few 3-pin fans online, but all of the fan headers on my motherboard are 4-pin PWM. You need to consult your motherboard's manual if such 4-pin header that you'll plug your 4-pin fan and your 3-pin pump/fan into is a PWM or a DC header. So you can set a sys_fan header to respond to cpu_fan temp address, or even set the cpu_fan header to respond to the gpu temp address, however you choose to do it. Plug water block on "CPU fan" motherborad's header, for the fans, the kit shoul come with a 2 / 3 way spliter, plug all the fans into splitter then to motherboard "Sys Fan" header, also you can conect them to a molex, with the proper spliter, Now that the unit is mounted, we will want to plug in power cables for both of the fans and the pump. To control the pump the fan header should support PWM. Desktop Boards … If you have a PWM fan plugged in, it can change speed based on PWM signal (changing current on constant +12V). If you plug a non-PWM fan on that header, it will run 100%, providing constant +12V. Can you plug a 3-pin fan into a 4-pin fan header? You can choose the fan header to work either in PWM-mode (constant +12V with PWM signal) or in DC-mode (variable voltage … If you love Harrison Ford movies, you'll love these throwback pics Ed Sheeran teases new album in 30th birthday post Britney Spears through the years: a look back at her greatest red carpet moments 3 Pin Fan To … The pump on the H115i is powered by SATA Power connector, it powers the 2 140mm fans and only has a ground cable that comes off to connect to the AIO/CPU header, the pump/fan speeds are controlled/setup via the USB plug on the pump.

I recommend a good tower type cooler with 120mm a fan and the option to add a second matching fan if it becomes apparent that you need one with a Y plug into the same port (rare, actually). You could even use the low voltage adapter from the Noctuas to reduce the voltage to 7V on the pump and see how it sounds and performs. 4 years ago. But there should be a 3/4 pin plug coming from the pump, that goes to the cpu fan header on the board. You don't have to use the iCue software. On others, it cannot. Fan splitters are generally not a good idea. If you do not use the PWM header for the pump it will run at 100% which may be too loud for some. You would need both conditions to use this device. It was followed by the use of ordinary resistors to slow the fans down, fans equipped with thermal resistors, various potentiometers for a wide range manual speed control, etc. Proper fan connector placement is shown in the figures below: Fan has a 3-pin power connector; desktop board has a 4-pin fan header: Note: when using a 3-pin power connector with a 4-pin fan header, the fan will always be on; there is no fan control.
