Question AORUS 2080 WATERFORCE PUSH/PULL

[szmirus]

Hey, I received PC with AORUS AiO cooling of 2 pushing fans AND ADDITIONAL 2 NZXT P pulling fans on the other side of the radiator.

I would like to ask you: how to synchronise these 4 fans?

I got NZXT Kraken x72 push/pull i7-9700k cooling "synchronised by BIOS" by my retailer - i dont know what does it mean. But he told me he couldnt synchronise graphic cooling the same way without AORUS application.

My mobo is AORUS Z390 PRO.

Thanks!

List your full system's specs like so:
CPU:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:

How are the NZXT Aer fans connected to your system? On another note, you should be able to identify the RGB componentry within Gigabyte's RGB Fusion app.

OK.

CPU Intel Core i7-9700K, Octa Core, 4.9GHz, 12MB,14mn
MOBO Gigabyte Z390 AORUS PRO
RAM g skill rpijaws v 16gb 3200mhz
SSD Samsung 970 EVO 250GB
GPU Gigabyte AORUS GeForce RTX 2080 XTREME WATERFORCE, 8GB GDDR6
PSU SeaSonic FOCUS Plus 850W
CHASSIS Fractal Design Define S2
OS WINDOWS 10

Pardon my english.

I ordered 2 sets of push/pull: one for CPU and one for GPU.

As i spoke to my retailer today 3 Kraken x72 fans + 3 additional nzxt fans cooling CPU (=CPU push/pull) + 2 additional nzxt fans cooling GPU are connected to "SYSTEM 5 PUMP" place, as it is called in BIOS, but 2 AORUS fans are connected to GPU (=GPU push/pull).

So: fans on GPU radiator got different information about temperatures: on the one side of the GPU radiator 2 fans use temperature sensor from GPU, and from the other side - additional nzxt fans use CPU temperature sensor.

Speedfan can't see my GPU, BIOS can't see my GPU.

Temperatures are low anyway, but i want my fans to be synchronised.

I will be grateful for help.

All 8 nzxt fans are connected to one slot and I cant reach them without opening the whole thing.
2 aorus fans are connected to GPU.
I really dont know what to do. Nobody got push/pull on GPU?

Ppl have been using push/pull on AIO's for years. The 3 pin fans on the gpu are voltage controlled and that voltage is supplied by the gpu. It's not like a regular motherboard header with a known 1A limit, so adding additional fans via splitter could possibly cause damage to the gpu. If they were 4pin PWM fans, that'd be different, just use a powered 4way splitter.

End result is there's no way to add 2 more fans, keep the fans operated by the gpu. SpeedFan should be able to find the gpu address/temp so you'd set the curve to use the gpu address, but if it doesn't see that, you are out of luck as far as sync goes.

Personally, I'd not even bother with push/pull on the gpu rad, you'd only get 3-4°C better temps at highest levels, that number getting smaller with lighter loads, so the added noise factor and cost isn't worth the hassle. That card runs cool enough on that super-sized aio rad that you'll not push its limits anyways. Most gpu aios use a 120mm rad just fine.

"POWER LOGIC DC BRUSHLESS FAN MODEL PLA12025B12HH-LV C18.09.26E 2 ball bearing DC 12V 0.5A"
thats whats written on AORUS fans.

NZXT are for sure 4pin, i checked that.

I have already bought this pair of fans...

So maybe there are some other programmes i can try to use. Other than speedfan?

In fact - speedfan sees gpu temp but cant see none of my fans, at all. Is it somehow useful in this situation?

Im thinking about connecting these fans separetly from the CPU ones and adjusting them to steeper curve in BIOS. CPU is usually cooler than GPU, especially when CPU kraken x72 is taking cooler air from outside, from front panel.

thanks for response
