Cant identify which fan is REALLY loud

[WilPad]

Firstly spec..(relevant bits)

Processor (CPU) Twenty-four-core Intel® Core™ i9-13900K (3.0 GHz) processor
ASUS® ROG MAXIMUS Z790 HERO motherboard (DDR5, LGA1700, USB 3.2, PCIe 5.0)
Memory (RAM) Corsair DOMINATOR PLATINUM RGB DDR5 5600 MHz 32 GB (2 x 16 GB)
Graphics card 24GB NVIDIA GEFORCE RTX 4090 - HDMI, DP
CORSAIR 1000W RMe SERIES™ MODULAR 80 PLUS GOLD power supply,
ULTRA-QUIET
Processor cooling High-performance CPU cooler Corsair iCUE H150i ELITE RGB series CPU cooler

When under a gaming load one fan REALLY gets loud with lots of ramping from quiet to loud.. , and im finding it hard to track down which one to do something about it !
Attached are all sensors (corsair Icue) ... This is taken when its loud. any idea whats going on here?
Ive set a custom fan profile in ICUE (BP) for fans 1-3 as shown
It SOUNDS like its coming from the area of the coolant fans, but that doesnt seem to be it from these numbers
coolant temps seem to be around 51-53 under gaming load (X plane 12 with VR )
Thanks in advance. !

Some more testing..I even installed Armoury crate to see if that allowed me to turn down whatever is really loud.. still cant work it out
This is when under load and noisy ..also included 4090 numbers..

 

[WilPad]

and this is when its NOT noisy..I just cant see what exactly is making it so loud !

Can you post your full specs from your order page? And looking at your coolant temp, I'd be very worried, that's way too hot. I don't think you've set your fan curve correctly if you're letting it get to that temp.

sure.... it has to be a translation as I ordered it from your Spanish website

Concerning that coolant temp looks too high !.it idles at around 47 deg .any help much appreciated
for now Ive reverted to the QUIET setting on each fan controlled by Corsair Icue...its a little loud at idle to be fair, but now temp is down at 40 at idle..way better..

 

[B4zookaw]

47C at idle seems very high too, but what is your ambient (room) tempature? For now, I'd change the profile of the H150i fans (top case fans I suspect) to the "Balanced" profile so they work off a standard fan curve.

I'd also use the uninstaller tool to uninstall Armoury Crate, I think it does more harm than good. I'd then go into the BIOS and set the front and rear case fans to Standard Profile. We need to address the system tempature before we start to worry about fan noise.

My guess is it's the GPU causing the noise, based on your screenshots. The H150i fan RPMs are very low (<1000 RPM), the fan curve for the GPU is very agressive, so any minor change in temp is causing the GPU fans to shoot up and down very quickly.

 

[WilPad]

Thanks for the reply.. will do those suggestions and report back
Ironically I only installed Armourcrate this morning to get control of the case fans LOL
Will post some numbers later..thanks. !

 

[WilPad]

Ok..big difference
armourcrate uninstalled
All Bios fan settings now standard,
All ICUE fans at balanced
coolant temp now 36 at idle, and 41/42 under extreme game load..
you might be right its the graphics card which is the one quickly jumping loud/quiet ..I had a good listen close up, but cant be 100% sure
So I guess have a look at the fan curve there and see what I can do... ?
Thanks for help so far. !

 

[B4zookaw]

Yes, adjust the GPU fan curve, but use MSI Afterburner to do this. Worth reading this article too.

 

[WilPad]

Had a good play around but even if I turn the fans to really low on the GPU with afterburner temporarily, under the load that ramping up and loud fan is still there !..its. a mystery to be honest ..at least I have made progress on lowering temps, but really would like to isolate that loud fan !
Re Fancontrol app from that link, it seems a great app, but does to not even recognise the cpu or cooller fans sensors to allow them to be controlled for some reason, even with Icue NOT running... so what apart from Bios can I use if not Armoury to control the onboard fans ?

 

[B4zookaw]

It won’t recognise any fans connected to the Corsair Controller, only fans connected directly to motherboard. It should recognise the front and rear fans, assuming they’re connected to the motherboard fan headers? Might be worth tracing the fan cables to see how they are connected.

 

[WilPad]

Hmm.. I will have a look with limited knowledge, .. but given this is the top of the range machine from PC Specialist , I would assume they had been connected correctly?

Never assume, as with all things, the weakest component is the human one, mistakes always happen.

Indeed, but a much bigger mistake could be made by some users plugging/unplugging stuff into the motherboard without the real knowledge to do so !

 

[B4zookaw]

No need to unplug anything, just trace wires from case fans to see where they connect. We’ll tell what to unplug after that 😉

 

[WilPad]

My front fans terminate on the coolermaster case circuit board as shown top left..probably the back one is there too (top plug?? ) ... didnt trace that as its all very well secured and runs behind panels This case does have a front fan control switch which has 3 speeds OR controlled by the motherboard in position 4 ..

 

[B4zookaw]

You’d def want it in position 4 if you want fan control to detect it and control it. And the board needs to have a connection running back to motherboard


Edit: looks like it should be, top right cable is the one that should connect to a fan header on the motherboard. See if you can trace to which one?

 

[WilPad]

Thanks..will try , thats a bit more tricky .. ! I can confirm that position 4 changes the fan speed to much higher , so its doing something.. !

 

[B4zookaw]

Try running the fan control detection process again with it in position 4 and see if it detects it.

 

[WilPad]

Hmm..it SAYS, no speed sensor controls react in the tests
BUT when it sets fans to 60% to set them up , they definitely change .I made sure to stop Icue first...heres what it looks like after running the wizard...
