Aurora R6, EKWB X360 kit

Hello, new to the forums and new to Alienwares version of pc's but have built a few back in the day . Anyhoo, I have a question about the liquid pump in that comes with the R6, and a few odds and ends if anyone might know. Here is the system build which you have probably read a thousand times .

7700k

850psu

16gb Vengeance 2133 ram

1060 6gb

Sound Blaster Z card

Thats is really, nothing fancy. So, as probably all of you do out there in the world you tinker with your new machine just like I tinker with supercharged engines most of my days to see just how much more you can get out of them with some degree of safety. So, what started all of this is I am going to be installing this card soon GTX 1080 TI SC2 Hydro Copper Gaming 11-P4-6599-KR. I know through reading and my own experiences with my friends 1080's that they tend to run a little warm. And, as we all know the Aurora case is a little tight in places for heat to really get in and get out. So, I was going to run a EKWB kit externally outside the case for the GPU cooling and figured well the stock CPU cooler is "good" but why not get a new block and plump the cpu in with the cooler and get better temps with my overclock. I have most figured out except when it comes to this pump assembly that I have used my Fluke on to see what wires are what ( since they are all black, awesome!). Now, they do not match standard 4 pin pwm seeing that looking at is from left to right when looking at the board the pins were as follows.

1 jumped to pin 4

2 was carrying 1.7 volts when running, I assume tach wire?

3 12 volts, bingo

4 ground and jumped to pin 1?????

I deal with alot of pwm in the auto industry now and I now that you can 100% duty cycle a pwm device with ground in vehicles for 100% operation. Is this the same on the pc board in the computer and why 1 and 4 are jumped together? I only ask because I downloaded Intel Extreme Tuning just to look at things through another utility and I saw it had CPU fan speed was averaging about 5 to 5500 rpm at all times with the pc running load or no load. So I am thinking my assumptions are correct about the stock liquid pump running wide open all the time.

So, now that you have read that novel is there anyway to wire this EKWB X360 kit in with its 4 pin adapter and get the Alienware control center to not give me a pump failure, fan failure, etc. etc.? I have read a few people with R5's and R6's using the Corsair h50 and Asetek coolers but I really want to get my cooler assembly outside my case for many reasons. So any help would be greatly appreciated and opinions would also be greatly appreciated. I know also, I should have just built my own rig and I would not be having to even think of things like this but I really like the look of the Alienwares and I always wanted to own one, so there you go .

Thanks again, Issac

Sorry, the pins would be

4 jumped to pin 1

3 1.7 volts

2 12 volts

1 ground jumped to pin 4

I went left to right instead of right to left,

AFAIK, the video card doesn't connect to the MIO-Board circuit on the Aurora-R6. Command Center / Thermal Control just reads the GPU fan speed over SM-Bus via I2C. I just reads it, there is no control. 

So, just swap the GPUs and you should be good to go. I suggest you just keep the separate "sealed" CPU/GPU coolers.

I wonder if the newly introduced GPU Radiator and Fan could go in the bottom of Aurora R5/R6, because it appears to be vented.

 

According to my notes running ePSA, CPU fan reads high-constant RPMs, so its really the pump impeller. Top-Fan is CPU radiator fan.

 

Search for my "Anti-MIO" ... but that is for Aurora R1-R4 and Area51-R1 (the ones with stand-alone MIO-Boards). Those Asetek units were "Dumb" while I suspect these newer Asetek units are Smart (have on-board controllers).

Happy 4th of July @Tesla & @ Isaac

I was 50/50 on whether to enter this thread, but here goes since I have a minute. I browsed the X360 install manual, the 1st passing observation was that the LED bulb runs off of a Molex 4pin - but R5/R6 only come with SATA cables - so you'd need a SATA-to-Molex adapter for it to work

I do not own this computer, but when moving from an air-cooler to a typical ASETEK AIO liquid pump (ie from an i3 to i7 6700k/7700k), some owners claim to have resolved any pump/fan errors or high-rpm fan situation, so look into it if you run into an issue come install day, regarding pump vs fan header relative to CmndCntr manual vs auto fan etc:

Page 26/27 of the online EK owner's manual seems straight-forward: simply find a pair of 4pin pwm headers, where one would assume the new pump plugs into the same mthrbrd header your stock liquid-pump now uses

I'm not 100% up-to-date regarding all Asetek models commissioned by various brands these days, but back in the day, and I could be wrong, but the NZXT Kraken was the only true PWM pump motor and had a 4-wire ribbon cable to run it, where-as all the rest used a 3-wire ribbon, non-pwm motor. If you're saying that the connector-end of your new stock AIO cooler has 4pins, has a jumper between pins 1 & 4, but the reality is it's just a 3-wire ribbon running to the pump motor, then the pump itself isn't / can't be a pwm-type (it'd be a garden-variety 3-wire Asetek with Ground 12v Tach) & the ground jumper from 1-to-4 is probably a way to manipulate the PWM signal so-as to trick the Bios and/or CmndCntr software to some advantage, which is odd, given what I'll say next below

Since you own this mthrbrd and pump, my confusion is that all of the pics online and in the PDF Service Manual all show a 3-wire pump fitted with a 3pin connector placed onto the central 3pin Pump_Fan header as below

if a revision occurred and a 4pin connector is now placed onto the far right CPU_Fan header, do tell, given that the air-cooler pwm fan normally went there. If you place a true PWM pump on that far-right 4pin header, I'd like to think there's no monkey-business engineered into the mthrbrd BIOS and/or software and that the PWM signal will work as it should, but who knows. It's safe to say that the pumps as-shipped (ground jumper 1-4 + 3-wire ribbon to pump motor PCB) aren't pwm types. I'd say to proceed with install and report back any issues if / when
