It doesn't control the pump at all, so it doesn't matter what you set the header to. Oct 5, 2021 · AIO's (All In One" systems are sealed units of the pump/cpu cooling block and radiator/fan you can not replace any parts as it's sealed system that is not designed for parts replacement, you must replace all AIO parts, the only critical item is the radiator size 120mm/240mm/360mm this must match the old units size if you want to use the same mounting location for the new AIO Jun 28, 2023 · CPU Fan là ghim cái fan Rad (3fan của LT720 dc chia từ 1->3) Sau đó vào Bios setting điều tốc cho Fan thổi rad đó. If you plug a 3-pin pump/fan on a 4-pin PWM header, such pump/fan will run in full speed 24/7 due to the constant +12V the PWM header provides. These fans are generally smaller and quieter than GPU fans, as the CPU typically generates less heat compared to the GPU. Like I said, i base fan/pump speed off CPU/GPU and Water temp. In the Kraken x63 manual, it says I can plug the pumps 3 pin into the CPU fan header OR the aio pump header. Dây PUMP thì ghim vào cổng AIO_PUMP trên main kia kìa, có ghi rõ ràng rồi đó.

In the case of our iCUE LINK coolers you actually have the choice to forgo that cable completely should you choose to, with my earlier comment still applying (depending on the motherboard you may have to make a change in the BIOS). The motherboard has a 4 pin header for a cpu fan, 3pin header for Cpu Opt, and a 3pin AIO header. I am getting max pump speed and my fan rpm is now stuck at 2700 and loud as heck. Pump is fine at 100%, and fans depends on the load and the kind of fans, as some are higher rpm and/or cfm than others. Luckily for you, you only have to deal with 1 cable. A CPU fan is adjacent to or directly over a CPU because it needs to blow away the hot air efficiently and quickly. 08A each. On my mother board I have CPU fan and Pump fan so I decided to plug my CPU fan-always needs to be plugged or computer won't boot properly, so CPU coolers/pumps go in there. 1GHz) Go into bios > advanced > monitor > cpu fan monitor > disable. This sounds like a dumb question, but I have the iCUE H100i Elite Capellix cpu cooler, and an asus z-690 motherboard.

Now, I have a Y cable that came with the cooler and that I'm using to connect both fans to the 1 CPU_FAN, but can I use the pump fan connector for the 2nd cpu fan and it would work just as good? PUMP_FAN headers got by default 100% PWM set by the BIOS. Normal 4-pin headers can supply 1A (12W), so enough for 95% of fans but not enough for D5 or DCC pumps (D5 needs 23W at max speed). In the end they are all the same, but with different names. Can be used for case fans, but modern CPUs can have large temperature reactions to load shifts - that makes fans ramp up and down all the time. The pump is set to a fixed speed and that's it. I know the Pump header should be better because it will run at full speed with a pump connected, but I've noticed that connected to CPU_FAN, the aio ru Even if, if you're turning up the pump to run some super insane workload your fans are going to be cranking regardless.

I got 3 fans, 2 connected to motherboard and 1 to the PSU (since i broke the yellow cable of the third fan connector). Dec 5, 2020 · Most CPU fan headers were programmed to be a CPU air cooler control and run from CPU temp only. My wife's system has an air cooler and I've had a couple AIOs, I honestly can't discern pump noise over case fans. The fans have to go in cpu fan header and cpu opt header. Since the AIO waterblock is closer to the CPU_OPT header, I would probably use that, feed the excess cable behind the motherboard. CPU_FAN is 1A? and PUMP_FAN1 is 2A or something? According to Arctic, the pump + VRM fan draws ~2. Sep 1, 2021 · cpu fan / pump fan / sys fan 질문 드립니다.

Sep 6, 2022 · The Pump will always run full speed as intended, and the fan speeds will be controlled by the CPU_FAN header automatically according to the temperature inside the CPU chip. SYS_FAN or CHA_FAN are for case fans. Then plug the pump into the pump header. Two fans on CPU_FAN1 with a Y splitter, attached to the CPU heatsink for CPU cooling Three fans on PUMP_FAN1, attached via the case's "dumb" fan controller for rear and top exhaust One fan attached SYS_FAN1 for front intake One fan attached to SYS_FAN2 for front intake I would probably keep your CPU fans on the CPU fan header for simplicity sake. Both CPU_OPT and CPU_FAN headers can be used for CPU fans, but, as the names suggest, only one of these is ‘optional’. Of course, if your CPU fan keeps the CPU sufficiently cool, this isn't an issue, and you can turn the warning off in the BIOS. The dedicated pump headers were normally 2 to 3 amps depending on how the board was designed. Compared to the CPU fan which is PWM/lets you control fan speeds (in this case the pump itself). From what I understand the pump header on the board just gives a constant power, but that's it. The PUMP connector may support more amps than the CPU fan connectors, that is why using that for the AIO pump is recommended. Then your pump always runs, and your motherboard has control over the radiator fan speed to increase our decrease cooling as needed. That way if it fails, you still have a fan working for you. If your fan isn't working temps will gradually go up but if your pump isn't working temps will skyrocket instantly. Dec 24, 2023 · Using a Y-splitter to connect two fans to the CPU_FAN header may also result in a CPU fan warning. I’m very confused My Mobo is a Asus ROG Rampage VI Extreme Plug it into the CPU_FAN header and make sure you manually change the pump speed close to 100% in the BIOS.
