GPU fan speed at 44% speed whilst idle

Hi guys, my apologies if this is the wrong thread for this issue but this is my first time using these forums.

I am currently having issues with my GPU fan speed being at 44% speed whilst i'm idle and the fan speed was at 0% before when at around 40-50C. (Proof of speed - https://imgur.com/2AlwPzK)

As far as i know, the GPU fans don't start moving until the temps reach around 55-60C and that was the case for my MSI Ventus 3080 3x plus 10GB LHR until recently.

I also set a custom fan curve on msi afterburner to force my fans not to be used when i'm idle but i noticed that my GPU temp didn't stop heating up until 70C when the fan curve kicked in
but it used to be stable at 50C when idle at 0% fan speed and i'm not sure why this is happening.

Case: CyberpowerPC Onyxia III Gaming Case - Black

CPU: Intel® Core™ i7-12700K 12-Core

GPU: NVIDIA GeForce RTX 3080 10GB LHR

Motherboard: MSI Pro Z690-A DDR4

RAM: 32GB DDR4/3200MHz Corsair Vengeance LPX Memory

Hard Drive: 4TB Seagate Barracuda SATA-III 6.0Gb/s 5400RPM

NVME SSD: 500GB Samsung 970 EVO Plus M.2 PCIe NVMe SSD

2nd NVME SSD: 2TB Samsung 970 EVO Plus M.2 PCIe NVMe SSD

Liquid Cooling: MSI MAG Coreliquid 240R V2240mm RGB

Fans: 4x CyberpowerPC Hyperloop 120mm ARGB & PWN Fan kit

Power Supply: MSI MPG A850W 80+ Gold

What fan settings do you have set in the BIOS?

Fan Control is a good app where you can see exactly what your fans are doing and can set them up anyway you like.

Here are my bios fan settings: https://imgur.com/wWKgR71

They are the same for each fan apart from the pump which i haven't touched.

The 4x cyberpower fans are connected via a splitter onto the motherboard and therefore i cant see the RPM of them but i was told that i can set them to PWM and the speed will change based on the fan curve.
 
Ok, I am no expert here. Was it working correctly before you did the fan curve in MSI Afterburner? Can you post a pic of that curve?

If you download the fan control software, it will tell you exactly what each fan is doing.

Is it even possible to do that with afterburner? The zero-rpm mode usually has a temperature cut off and a minimum fan rpm, so fan curves can't usually manage this in a gradual way. What prompted you to start using afterburner in the first place?

Is the behaviour different if the card has never reached the temperature to spin them up, to when you've been gaming and returned to desktop?
 
Does it not downclock at idle?

This is mine.

I didn't know of any other software at the time and i was experiencing high GPU temps when i first bought the PC and the fans weren't being used when reaching high temps and so i had to intervene and create a custom fan curve on afterburner.

Also, iv'e come to the realisation that my GPU isn't downclocking when i'm idle which is weird

What happens to the memory clock with just one display connected? High memory is a result of multiple monitors. The high core speed though is strange

FIXED: The power management setting in nvidia control panel being set at ‘prefer maximum performance’ was the cause of the clock speeds being abnormally high when idle and i have now changed it to 'normal' and i'm no longer experiencing the issue.

Appreciate the replies nonetheless, thanks.

I had this with my 3080 when I first got it in 2020. I was so used to setting max performance previously with Nvidia cards which would still clock down when on desktop when using (idle). With the 3080 it was just on all the time, something must have changed but I didn't look into it the reason why, figured it out like you have and went on my way.

Does anyone have any info why this has changed? It's no biggie, just curious.

Nevermind, the issue isn't fixed. I went on 3dmark and it didn't downclock when i closed it and went idle.

I seem to remember there was a driver awhile ago that got gpu stuck even after game closed, but I can't remember if it was amd or nvidia.

Btw, how did you post an image on here without using an external link? I can't seem to just copy and paste an image on here

Add your screenshot to imgur. Hover mouse over the image and click the 3 dots then select Share Options then the BBcode.

Paste the BBcode into your post and it should embed the image.

Does the 3080 downclock and fans stop with only 1 monitor? (also asked by shankly1985)

Yes it does downclock with a single monitor but it also downclocks with 2 monitors plugged in. I recently went on 3dmark and the clocks speeds didn't downclock when i closed the application but i believe the issue has been fixed after i did the recent windows update because my GPU is now downclocking after i did a system restart.

Glad you've got it fixed from your latest post. I went and put maximum performance back on and strangely enough, it's downclocking on idle with that setting on. Now I'm even more confused lol. It fixed my issue at the time so maybe it was a driver or a windows update I hadn't applied. Thanks as I wouldn't have bothered testing that again if it wasn't for your thread.
 
I remember reading posts about the 144hz monitor on a dual monitor setup causing this problem. Set that monitor to 120hz or something and see if that helps.
