hey all, can someone help please me out with a couple of problems as Im on a first build and I want this exactly right.

I got the STRIX Z270E Mobo and and the NZXT X62 KRAKEN AIO Water Cooler, Im just trying to figure out the correct connections of the fans now for the most logical control in the BIOS. (the instructions are a bit vague)

The X62 KRAKEN has a SATA type connection coming off it that splits into 3 sections, one is to the SATA Power, no problem, the other is a fan connection splitter so the two fans on the X62 front radiator I’m assuming run together as one unit (makes sense).
The other is a 3 pin connector, on the instructions for the X62 it says plug this connector into the CPU _FAN header on the Mobo. OK so I DO have this connection on the Z270E board but I also have a 4 pin header labeled AIO_PUMP close to where the first PCIE_X1_1 slot is…
Can anyone tell me which one I should use, does it make a difference? Does the AIO_PUMP header bring options into play in the ASUS BIOS that the CPU_FAN header doesn’t ? Im assuming this AIO_PUMP Header is a not on every board and NZXT just instruct to make a generic connection to the CPU_FAN header. Can someone tell me whats going on here?

And second question, Im left with two exhaust fan connections to place (Case is NZXT S340 Elite) for top and rear fans, Ive got nothing clearly telling me where to put these two connections so Im guessing the headers CHA_FAN1 & CHA_FAN2 take these two right?

The reason I ask that last question is because there are two more headers labeled CPU_OPT at the top of the board right next to the CPU_FAN header and another one right next to the AIO_PUMP header labeled H_AMP_FAN.

If anyone could tell me exactly the connections should exactly go here It would be well appreciated.

Cheers for all your time anyway lads....

Richie

The AIO Pump Header (AIO_PUMP) is set at a default full speed (DC/100% Speed), while most of your other Fan Headers (CPU_FAN, CPU_OPT, CHA_FAN1, and CHA_FAN2) is default as Q-Fan Controlled (PWM/Variable Speed). All these headers provide a max. current of 1A (or 12W). The High Ampere Fan Header (H_AMP) is the same as your other Fan Headers but can handle up to 3A (or 36W). Settings of all these fan headers can be changed/controlled through BIOS or Asus Software.

You have several option to go with connecting your Kraken X62, Radiator Fans and Case Fans in your Z270E motherboard.

You can connect the Kraken X62 based on NZXT's instructions: Plug the 2 Radiator fans into the Kraken X62 itself (the fan connection splitter of the pump), then, plug the X62 into the CPU_FAN as a whole unit. As the NZXT mentions that the Kraken X62 was designed as a "variable speed pump", then, plugging the whole Pump and Rad Fans in the CPU_FAN means the speed of both pump and fans will be controlled based on the CPU temps (unless overridden by certain fan curve in BIOS/Asus Software).

Alternatively, you can also connect just the pump of the Kraken X62 into the AIO_PUMP Header based on Asus' instructions, but, connecting the radiator fans into the CPU_FAN to change fan speed based on CPU temps. The idea is running the pump at full speed 100% of the time (which is ideal for most AIO coolers, given the very small amount of liquid flowing) while the fan's rpm changes depending on the CPU use/heat. You can use a different splitter (sold separately) or a fan hub (sometimes included in the case, but, also sold separately) in connecting the 2x radiator rans into a single header (the CPU_FAN). You can also connect 1 fan in CPU_FAN and 1 fan in CPU_OPT.

For the case fans, yes, you can connect it to whichever fan header is available -- just pick the closest if you want to avoid any long wire runs or cable clutter.

Hope this helps.

CPU_FAN and CPU_OPT is controlled by the cpu temperature so in yoru case if you dont want the radiators fans to be controled by the pump, you plug one fan in CPU_FAN and one fan in CPU_OPT, they will both react to cpu temperatures. The reason why the fan has a 3 pin fan header to conect it to CPU_FAN is that if you plug your radiator fans to the pump and elave the CPU_FAN empty the motehrboard will nto start, it will display an error that the cpu fan is not working. So your choice, radiators fans in pump and pump conected to cpu_fan or radiator fans conected to cpu_fand and cpu_opt and pump conected to AIO_PUMP(you may not need to conect the pump at all taking in consideration that the power is supplied by sata conector). About your spare case fans, yes they go into cha_fan headers.

Thanks Dragos, John, I hooked up to the 62 to the CUP_FAN for now, Think i'll try both ways and see which way runs the CPU the coolest. But for now i'll try the CPU header first.
I don,t suppose one of you awesome chaps can advise me of what sort of temperature envelope my CPU's comfort zone should be around?, Its an I7 7700k with a Strix GTX1070 Card. Will be doing hopefulls some maxed out gaming on it with a bit of an overclocking.
Cheers again anyway lads, great help.

I don't have a better answer than them, but I have a question. With your Strix and the X62, are you able to utilize all 4 ram slots?

I'm looking to do a new build and keep reading the X62 blocks the first ram slot.

You can use all 4 slots without any hindrance to the X62 pump. Sample builds:

Hey Cosmic I exactly the same build as you. Just wondering how u ended up connecting ur fans? I had the same issue of where to connect the fans. I ended up finishing my build , all fans seem to be working fine for me. Just curious what ur outcome was .

Hello

I have your own system and ram but the first ram is slightly touched by the pump down, is it a problem?

Cosmos, how did you end up installing the x62? The responses from Dragnos and John were helpful but I may just need a picture to complete the install onto the mobo.
