Question High specs graphic card but fans go crazy with 2 monitors connected and no apps running

[Star2222]

Hi,
I have a system with this config:
- Motherboard: MSI MAG B550 TOMAHAWK Motherboard ATX
- AMD Ryzen 9 3900X 12-Core Processor 3.80 GHz
- 64 Gb of RAM
- Graphic card: ASUS GeForce RTX 4070 12G DUAL EVO OC Gaming Graphics Card - 2550MHz Boost Clock, GDDR6X, PCIe Gen 4, DLSS 3, HDMI 2.1a, 3 x DisplayPort 1.4a

that graphic card is supposed to supports 4K & 8K HDR for 3 displays, but... when I connect the following monitor configurations I get the following:

- Philips PHL 328E1 (running at 3840 x 2160) by itself all works well
- Philips PHL 328E1 (running at 3840 x 2160) and a second monitor (old Ace 23") running at 1920 x 1440 all works well too
- Philips PHL 328E1 (running at 3840 x 2160) and a second monitor KOORUI 27 Inch Monitors, 4K Computer Monitors UHD(3840 * 2160) running at only 2560 x 1440 (windows recommended and highest available for it in Windows) the PC fans go crazy even with no application open (I don't know if it is the CPU fan or the Display card).

Any idea why that is and how I can solve it?

Thank you

I see some things haven't changed with Nvidia;
https://www.nvidia.com/en-us/geforce/graphics-cards/40-series/rtx-4070-family/#specsmodal
go here and if you click on view full specs you'll see that you can work with 4K displays at 120Hz, which leads me to ask what your display refresh rates are for their respective resolutions. How are the monitors in the last scenario tethered to the discrete GPU?

(I don't know if it is the CPU fan or the Display card).
You might want to confirm where the noise is coming from. Roll up sheet of A4 paper into a cylinder, then hold up one end to your ear while the other end is used to probe for the source of the noise.

Which display driver version are you on for your Nvidia GPU? To add, it's normal for the clocks on the GPU to go up when you add additional displays.

BIOS version for your motherboard at this moment of time?
