ASUS ROG STRIX 1080 Ti fan connector

[WillYo]

Hi,
I'm about to swap my Strix cooler for Raijintek Morpheus II Core Edition and faced an issue. PCB has 6-pin fan connector and I have VGA 4-pin PWM adapter like this: https://gelidsolutions.com/thermal-s...m-fan-adaptor/which swaps basic PWM connector to 4-pin VGA fan connector. It's obvious that it wont fit but can anyone tell me what are the pins on the PCB so I can make my own cable? Where to connect black, red, yellow and blue in the 6-pin connector on PCB?
Stock fan cable has red, two green, yellow, blue and black wires. All yellows go to same pin just like blue and black ones. Red and green ones goes to separate pins.

That card has two normal 4 pin PWM headers for letting your gpu control some system fans. I’d think you could just use those.

Dunno how the card would react to having nothing connected to the smaller 6 and 4 pin connectors.

One would have to assume, the same way it would with a water block on it, normal.

I say install the cooler, plug the fan/s into the 4-pin PWM fan connectors, boot PC and see if fans spin. That cooler is beefy enough to take the heat load of the GPU at idle without killing anything while you check to see if it working properly. Also, no reason you cant use extra motherboard fan headers to power said fan/s, although some near it may not be controllable.

It looks like the 6-pin connector is for(what we call in automotive terms) a wiring harness. Which in turn connects to two 4-pin fans, and one 5-pin fan. Or, rather, that it has two 4-pin fan connectors, and one 5-pin fan connector. I don't quite get why one of the fans is connected with the 5-pin connector. Since it looks like all three fans are 4-wire 12V fans(same part numbers even). And the fan that connects to the harness with the 5-pin connector isn't wired to the 5th pin(it doesn't look like there's even a pin in the 5th hole).

Anyway...the harness has the male connectors. Which means you can't connect to it with that adapter you have. It should be pretty easy to figure out the wiring arrangement of the harness to be able to make it work with any two 12V fans though, if you have the fans and the harness to disassemble and look at(or possibly just from the pics you can find). You'd just have to do some modification to make it work with the common case fans you'd be using with a Morpheus II. Or make your own harness, with the knowledge of the wiring arrangement having been aquired.

Just as a suggestion. If you can refund the Raijintek, i would send it back and buy a Accelero Xtreme IV. Granted, it doesnt look as good as the Raijintek. but it cools a 1080Ti really well. you can still use your frontplate that cools the VRMs and memory. the backplate might also work.

The Asus Strix cooler is supposed to be pretty good though. You could even just take the fans off it and zip tie your own fans on there because going from the stock strix cooler to the Raijintek isnt really a huge jump. they are almost the same product.


I suggested the Accelero, because the fans have a connector that fits the 1080Ti ones. (and i also use the accelero on my 1080ti with good results)

I still don't see why all the fuss. Stick the fans into the 4-pin fan headers and boot the thing. Although, OP has not been back since he made the initial post.

 

[MrGenius]

Meh. Whatever works. It's good to know what all your options are anyway. In case one way, or another, doesn't work like you want it to.

Thanks a bunch guys! So, I have tested the 4-pin PWM connectors on GPU that the fans are working. Tested them with GPU Tweak but the problem is that I don't wan't any more software to control fans and temps than there already is. I use iCue with Commander Pro to control case/AIO fans and MSI Afterburner for GPU. If things won't start working from the 6-pin connector then I'm about to use Commander Pro for GPU fans also.

I managed to find a 6-pin connector that fits to the connector on GPU and have already tested to connect the wires to a 6-pin VGA connector just like on the original wire harness excluding two green ones (see the picture) but the fans are not spinning at all. I was thinking that will the card need all of those greens and red to be connected to work? As you can see from the picture, greens goes to the first two fans and the red goes to third one and turns to green too at the last connector. Are those the RPM signals? Can I Split the red from my new fans and connect them to the free pins on the connector?

Searching the internet lead me to this post, and it seems like it wasn't resolved.

A PWM fan adapter works perfectly, like the one linked.
It just needs to be connected to the right (->) side of the connector.
The right side is where the black, yellow, green, and blue wires on the original cable are connected.

I used a Y-cable to connect two fans (and hope they aren't drawing too much power).

Might I ask which PWM adapter you are referring to ? I cannot see a specific link !
I'd also like to find an adapter to be able to connect the 6 pin harness to the external 4 pin connectors on the card. My fans still work but for some reason (maybe the PWM circuit is dead) they wont work on the original 6 pin connector. I tested the external 4 pin connectors with a case fan and thos work fine.
So now I'd like to connect the original fans (6-pin) to the external (4-pin) connector.
Any help is really appreciated !

I was referring to https://gelidsolutions.com/thermal-solutions/accessories-pwm-fan-adaptor/.

A 4 to 6 pin adaptor where one pwm input is connected to the three pwm outputs seems a bit to niche to exist. But I hadn't looked, so who knows.
