I'm experiencing an odd issue with the fans on the GPU that I recently bought from overclockers.co.uk. Under load, the commanded GPU fan duty cycle does not change, but the fan RPM frequently and audibly dips/stalls. I managed to record the behaviour using Furmark, RTSS, OBS and a mic.

I tried setting the GPU fan duty to fixed values (e.g. 60%, 80%. 100%) using Palit's control software, but the behaviour persists. I'm baffled, any suggestions gratefully received.

Perhaps contacing overclockers.co.uk should be your first port of call whilst the card is still under warranty. It could be an issue with the fan or the graphics card.

Also worthy of note, but unrelated, is the note at the bottom of the PCPartpicker screen regarding your PSU/Motherboard choice.

"Note:The MSI MPG X570 GAMING PLUS ATX AM4 Motherboard has an additional 4-pin ATX power connector but the Corsair RMx 650 W 80+ Gold Certified Fully Modular ATX Power Supply does not. This connector is used to supply additional 12V current to the motherboard. While the system will likely still run without it, higher current demands such as extreme overclocking or large video card current draws may require it."
