AIO liquid cooler plug into cpu header or water heart header

How-do-you-do,

I recently bought a corsair h100i v2 cooler, and I'm wondering which header to plug the pump into. I bed that in the manual information technology says to plug it into the CPU_FAN heading, only my motherboard has a dedicated H2O pump connector (the ASUS Z170-A).

I'm wondering if I should plug the pump into that water pump header and depart the CPU Fan header blank. Volition it case whatsoever problems to plug the pump into this water heart head, lead the cpu fan header blank, and still cud the radiator fans into the plugs coming from the water occlude?

Thanks in feeler!

Here's the body covering. Barbary pirate AIOs let in basic instructions that are so generic they'll put on to any mobo made. Barbary pirate recommends installing the pump to the cpu_fan head for 1 half-witted reason, the pump will usually fail before the fan and mobo's have a failsafe to protect the central processor. Mainly, if in that location's no rpm registered on the cpu_fan header, the pc won't boot or shuts down immediately. So if the pump fails, the pc is supposed to shut down. However, on basic AIOs this leaves temp control at the mercy of a sys_fan header, which has different temporary worker setups from a cpu. Most cases don't ever reach past 40°C whereas cpus can easily hit 70°C.

The h100i doesn't use the cpu_fan header for temp control, IT uses the USB cable and Barbary pirate Link software, so with that method, arsenic semipermanent as 'something' is plugged into the cpu_fan header, all good.

Personally, my system is contra recommended, the rad fan is on cpu_fan and the ticker is on cpu_aux which is a non-controlled straight 12v so I have temp regulation, volume and velocity control of the fan and still have max ticker performance, which is what most AIOs indigence, not a variable speed pump.

You volition absolutely call for something plugged into cpu_fan or the PC leave not boot. Having a consecrate header for cpu_pump just sets grassroots AIOs up same arsenic mine, but being an advanced AIO, your actual power is supplied differently, but still inevitably to translate the tachometer wire as having genuine revolutions per minute, thereby the mobo assumes at that place is a working tank attached to the CPU.

Not really a solution, but I am having the same oppugn. I have a Silent Loop, which has deuce 280mm fans that connect to my ASUS X99A-II MoBo via a y-telegraph. I have them connected to the CPU_FAN connection. I cause the pump affined to CPU_OPT and appears to be working and the PUMP runs at a constant 2200 PRMs. However, I am wondering too, if I should use the W_PUMP connection.

You mean cardinal 140mm fans ? Yes, heart should go around to a place where it should let constant voltage. Pump should turn constant fastness and fans on radiators could be regulated by CPU_Fan so they vary speed according to CPU temperature. Some WC cooling systems have also USB connector over which SW tin shape all speeds. It's also good to have pump on a connection that derriere discover it's speed and raise warning device if pump would stop. Just a prophylactic sport.

Present's the boney. Corsair AIOs include staple instructions that are so generic they'll practice to any mobo made. Corsair recommends installing the pump to the cpu_fan header for 1 simple reason, the pump volition usually fail before the fan and mobo's have a failsafe to protect the cpu. Mainly, if there's no rpm registered happening the cpu_fan header, the pc won't boot operating room shuts down immediately. Then if the pump fails, the PC is supposed to shut behind. However, on basic AIOs this leaves temporary worker control at the mercy of a sys_fan header, which has divers temp setups from a cpu. Most cases don't ever so get through prehistorical 40°C whereas cpus can easily hit 70°C.

The h100i doesn't use the cpu_fan header for temp control, it uses the USB wire and Corsair Link package, then with that method, as oblong atomic number 3 'something' is blocked into the cpu_fan header, totally good.

In person, my system is contra recommended, the rad fan is on cpu_fan and the ticker is on cpu_aux which is a non-controlled straight 12v so I have temporary worker regulation, volume and speed manipulate of the fan and still hold easy lay ticker performance, which is what nearly AIOs need, not a variable speed pump.

You will absolutely pauperism something blocked into cpu_fan or the pc will not boot. Having a dedicated header for cpu_pump just sets basic AIOs up same As mine, but being an advanced AIO, your true power is supplied differently, simply still inevitably to read the tachometer wire every bit having actualised rpm, thereby the mobo assumes there is a working cooler attached to the cpu.

Here's the skinny. Corsair AIOs include basic instructions that are then generic they'll apply to some mobo made. Corsair recommends installing the heart to the cpu_fan header for 1 simple reason, the ticker will usually go before the fan and mobo's have a failsafe to protect the cpu. Primarily, if there's no rev recorded on the cpu_fan header, the personal computer won't boot or shuts down immediately. Sol if the pump fails, the pc is supposed to compressed bolt down. However, connected basic AIOs this leaves temp control at the mercy of a sys_fan header, which has different temp setups from a cpu. Most cases wear't ever make past 40°C whereas cpus terminate easily slay 70°C.

The h100i doesn't use the cpu_fan header for temp control, it uses the USB wire and Corsair Link up software system, so with that method, Eastern Samoa yearn as 'something' is plugged into the cpu_fan header, all good.

In person, my organisation is contra suggested, the rad fan is on cpu_fan and the pump is on cpu_aux which is a non-controlled straight 12v so I experience temp ordinance, mass and speed controller of the fan and still deliver max pump performance, which is what about AIOs need, not a variable speed up pump.

You will absolutely need something obstructed into cpu_fan OR the pc will not bring up. Having a dedicated header for cpu_pump just sets staple AIOs up same arsenic mine, merely beingness an advanced AIO, your actual power is supplied differently, but still of necessity to translate the tachometer wire as having actual rpm, thereby the mobo assumes there is a working tank attached to the cpu.

Thanks for the reply!

So supported what you'Ra saying, It'd embody fine if I were to plug my radiator fans into my CPU_FAN headers (I have two central processing unit fan headers, so I could plug both radiator fans into those), and then I could use the dedicated piddle heart header for the ticker, even though that isn't exactly what the blue-collar says? Do you know if there would Be any problems therein setup?

Ty. When I eldest set up mine (married woman's actually) I did as corsair recommended. Being a 3pin, the pump ran at a constant rate, the cpu_fan lintel is dedicated pwm not analog, you necessitate a 4pin for any keep in line. This set my fan at always at 100% since the central processing unit was overflow 40°C at anything beyond idle (i5-3570k @4.3GHz). Asus fanXpert was great for getting that all sorted stunned, but I still didn't scram honest cpu temps. So the headers got switched. FanXpert is great on that information technology has alarms. Since flatbottomed at 100% load along p95 26.6 small fft the temp doesn't go on the far side 70°C for any reason, I set the dismay for 72°C. Now if the cpu overheats IT's one of two things, pump nonstarter or sentence to cleanly the radiator. Simple.

Ty. When I first set up mine (wife's actually) I did as Barbary pirate recommended. Being a 3pin, the ticker ran at a continuous rate, the cpu_fan cope is dedicated pwm not analogue, you need a 4pin for any control. This set my lover at always at 100% since the cpu was well over 40°C at anything beyond idle (i5-3570k @4.3GHz). Asus fanXpert was great for acquiring that all sorted out, but I still didn't receive honest cpu temps. So the headers got switched. FanXpert is great on that it has alarms. Since even at 100% load on p95 26.6 miniature fft the temporary worker doesn't die beyond 70°C for any reason, I set the alarm for 72°C. Now if the cpu overheats it's one of two things, pump failure or clock time to clean the radiator. Simple.

[Peachy post, Karadjgne! Hope you don't mind if I follow up? I have an Asus Maximus Hero IX board and plan on victimization the Corsair H100i v2. I was going to merely connect the fans on the radiator together, and plug the pump into the AIO header. I wasn't going away to use the USB. What do you mean when you said "the headers got switched"? You indicated your solution was to hook up the Radian fans up to the CPU fan head, and the pump to the CPU Aux, which would be the CPU_OPT connection connected my add-in I get into. Did you switch the header connections? Did you have the USB connected for the pump? I only have one USB connector on my board. If I use it I can't snarf sprouted the one happening the front of my reckoner.

I think I might have bit off more than I can chew. I have a be quiet dark base pro 900 case, and am relieve trying to figure out how where I should gazump in the lead the PWM cable from their case devotee hub. :)

Thanks!

USB is just for control and to send information to the system. IT comes with a utility for that.

There's au fon 2 different types of aios, software controlled, commonly by USB, and ironware controlled by motherboard and bios. The h55 I have is the second one, there is no USB hookup. The h100i series you have is the first kind. However, information technology's as wel backwards compatible, so if you choose not to use the Corsair link, and privation a standard bios 'set and leave' and then you crapper. You buttocks do it as canonic Barbary pirate's instructions, with heart on cpu_fan and fans elsewhere, or you can fans on cpu_fan and pump elsewhere, just you'll still use the supplied Sata for power, the tach on the 3pin gift you rpm. This'll need that in bios you set that particular cope to 100% duty wheel, which maxes out pump belt along, permanently.

The h100i series you throw is the foremost kind. However, it's also backwards compatible, so if you choose not to use the Corsair link, and desire a standard bios 'set and forget' past you can. You can do it as standard Corsair's instructions, with pump on cpu_fan and fans elsewhere, or you can fans happening cpu_fan and pump elsewhere, just you'll still use the supplied Sata for great power, the tachometer on the 3pin giving you rpm. This'll require that in bios you set that particular header to 100% duty cycle, which maxes out ticker speed, permanently.

Thank you for the answer. Information technology will take me a bit to digest, but I call back I understand what you are expression. In any event, you evoke I don't employment the AIO connector on the Asus Her IX motherboard? The support says that header is 12w and the default speed is Full Speed, patc the CPU_Fan & CPU_Opt headers, and the 3 Anatomy Fan headers are 12W and Q-Sports fan Restrained.

I bash prefer the set it and forget it.

Thanks!

If you privation to, you can utilisation the pump 3pin on the cpu_pump and the fans on cpu_fan lintel. That's very well. Even as long as the cpu_fan header is inhabited past something. You won't be victimisation much of any of that 12w (1Amp, which is modular) on the cpu_pump header as the actual pump itself is powered aside the Sata mightiness from the psu. That header will in essence scarcely be used for the tach wire, so in fanXpert you'll escort the pumps rev. I like fanXpert, a lot, it has this neat setting for alarms which many a don't, and so take a peak at what rpm the pump normally runs at, and set the appal to go off if it drops 400rpm or so. The fans don't need an warning signal, they are changeable speed, and if the fan with the tach off the splitter reaches 0rpm,tbe pc will shutdown anyway because of the cpu_fan security.
On my Asus board, all headers are under Qfan able ascendancy take out cpu_aux which is grayed out, it's 12v dedicated. Since your fans are pwm, you won't have an issue connected cpu_fan header as that's a ordained pwm lintel. You'll nerd a 4pin splitter for the fans, a 3pin won't work.

If you deficiency to, you bathroom use the ticker 3pin on the cpu_pump and the fans on cpu_fan header. That's fine. Just as lengthy As the cpu_fan head is populated by something. You won't be using often of any of that 12w (1Amp, which is standard) on the cpu_pump cope as the actual pump itself is battery-powered past the Sata power from the psu. That header volition basically just be exploited for the tachometer wire, so in fanXpert you'll see the pumps rpm. I like fanXpert, a slew, information technology has this neat setting for alarms which many wear't, so take a peak at what rev the ticker normally runs at, and set the alarm to go off if it drops 400rpm or so. The fans don't need an alarm, they are variable quantity speed, and if the fan with the tach off the divider reaches 0rpm,tbe pc will shutdown at any rate because of the cpu_fan security.
On my Asus circuit card, all headers are under Qfan able manipulate except cpu_aux which is grayed out, it's 12v sacred. Since your fans are pwm, you won't have an write out on cpu_fan header as that's a dedicated pwm header. You'll nerd a 4pin divider for the fans, a 3pin won't process.

Keep hearing this CPU_Fan essential follow inhabited folderol from all over the place. If you try it you will get an error when posting stating the Central processor! is Bla Bla Bla!, press F1 to get into bios, survive to monitor, go to CPU and select {Ignore} from the drop-downcast,Your done! and you can now start your system without the CPU_Fan or Opt_CPU_Fan heading inhabited. I perform this day in and day out when setting up my AIO although in your case you'll probably come up something to connect there.

Maybe. There is a work around thereto, but it necessitates the usage of SpeedFan. With SpeedFan, you can do apiece header to supply power/pwm reported to which ever address you choose. So you can hardening a sys_fan header to respond to cpu_fan temp plow, or even go down the cpu_fan head to answer to the gpu temporary worker address, however you choose to do it. You'll and then just tailor the fan curves to what output expectations you have. SpeedFan is the only software that'll do this, all others, including Asus fanXpert won't, they use default on addresses. Indeed if you use bios or fanXpert, then yes, you are stuck with no mainframe temp ascendancy, if you use SpeedFan, you call for to dig into it to get that totally setup.

CPU cooler fans are most important to control, start because they are largest and noisiest in whole organisation and with GPU fans, most important. I tail end't see no valid reason not to use them at CPU header. Newer MBs have BIOS options to "power train" CPU and other fans for most scheme self-moving control. Each type of fan header has control by own sensor. This Asus of mine has 4. Even CPU1_Fan and CPU2_Fan are separately controlled so push-pull fans turn at different speeds for best performance.

One of the advantages of having a newer gen mobo. Both of mine are z77's and the cpu_aux cope is a 3pin constant 12v. Great for pumps, either baritone level aios or setup without using Barbary pirate link up etc, where the winnow is on cpu_fan header. But does mean that for titanic towers with double fans, either I weft 1 for a constant speed, maybe use a LP or ULP adapter, or move a splitter to cpu_fan and forgo usage if cpu_aux. Control would have been nice, but it has nobelium addressable feature, so non symmetrical SpeedFan does anything.
