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.

  • In the video, I see the fan speed is keeping 58% constantly, can you elaborate a bit more? – Bilo Aug 15 '20 at 11:28
  • That's the fan duty that Palit's default fan curve is resulting in. Here's another video in which I've pinned the fan speed to 100%, and the problem persists: https://youtu.be/6W-RD07TupI – Ethan Fowler Aug 15 '20 at 17:16

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."

  • I have contacted them and Palit in parallel, but didn't want to return the card if someone more knowledgeable than me knew of a solution. I was under the impression that the 4pin wasn't necessary, I'll do some more research. – Ethan Fowler Aug 15 '20 at 16:17
  • I checked again on the 4-pin ATX power (CPU_PWR2) requirement, and apparently it's only required if you're doing extreme overclocking (i.e. high CPU currents). – Ethan Fowler Aug 15 '20 at 17:13
