Quiet spec PC arrived and it's not quiet at all

If you have a close look at the pin you have marked "3" in the first picture you sent, and also the zoomed in one that doesn't have the numbers on it, the plug isn't pushed in. It's came away from the controller. No signal from this fan back to the motherboard may have stopped all functionality of the control so the other 2 fans are running full blast.

 

[jergil]

Ah I see, sorry I thought it looked as though it wasn't plugged in in the first image, but when zoomed in, to me it looks as though the plastic plug housing is flush against the header and IS plugged in, but the pins are visible through the housing of the plug, making it appear not to be....if that makes sense. Anyway, seems pointless to speculate further as I can just check when I get home!

Thanks again for all your help! Will post update this eve.

 

[Scott]

Ahh yes I think you're right. I was hoping it was going to be a an easy fix of just plugging it in home all the way haha.

If the fans are in fact connected to the hub then my guess is it's either configured incorrectly or impossible to configure correctly without a PWM fan attached.

Edit: Can still be fixed with the commander core though, or direct connection to motherboard with a voltage option on the headers.

 

[SpyderTracks]

In the BIOS, the header that the case fan circuit runs through which I think is CH_Fan1 needs to be set to DC in the BIOS rather than PWM

At PWM, any fans connected to that header will run at full speed as they don’t have the 4th pin that regulates speed.

When they’re set to DC, it adjusts the voltage to the fans as a way of reducing speeds.

 

[SpyderTracks]

On page 10 of the manual it gives you a brief guide on the QFan section of the BIOS, this is where you need to set the CHA1 FAN to DC in the drop down in the top right.

From there you can either adjust the fan curve within the BIOS.

Personlly, for case fans, I would never set a curve, I'd find an optimal speed where the fan noise is just on the cusp of audible, that you find won't interfere with anything, then set a static speed there.

Once you're happy with that one, we can then sort out the Corsair AIO, but that's an awful lot easier as it can only be setup one way and is controlled by iCue

And apologies @Scott he may well have advised to connect the case fans via the iCue controller which is another good (better?) route also, don't mean to step on toes, rather a reactionary post as I've seen this before with the loud fans on this case and work has been a bit manic so haven't had time to read through posts

 

[Scott]

Either (or any) solution is fine IMO. It's always a preference though.... .some people don't like the BIOS and it gives them the fear, so prefer UIs like iCue, which is why I would consider it.

I've long been an advocate of the static fan profile in a case, as you know @SpyderTracks. This is easily done with either option but more direct through the BIOS/Motherboard as any future installation/upgrade/software issue, etc, could mean having to reconfigure. Typically with BIOS and a flat setting it's one and done.

Yeah, very well put. BIOS can be offputting for some, but is a more resilient method IMHO for this kind of case issue. As you say, one and done, doesn't matter what the software does in windows. And then if you did want to alter it, you can install a windows app to do so.

@SpyderTracks @Scott

Thanks both, the method I choose will probably be the one which requires the least snipping of cable ties
I'm hoping all that's needed is a quick dip into the BIOS (thanks for the manual, Spyder), set the fan control to DC, and adjust the speed to a lower static value

 

[jergil]

Found the culprit!

I'm guessing that is max RPM?

Flat 60% is as low as it goes and the RPM didn't budge, even on DC control mode.

So... pretty sure the two front fans that have been plugged into the CPU_FAN header(s) (I'm assuming there are multiple?). I'll stick them into the 3 pin case fan headers and report back.

 

[jergil]

@SpyderTracks @Scott

Welp, I was wrong. They are plugged into the 3 pin headers on the hub case, where they are supposed to be.

The PWM header is plugged into the CHA_FAN5 header on the mobo, where it's supposed to be.

But... in the BIOS the front fans are registering as being the CPU_FAN and locked at around 2.3k RPM

Any ideas, other than plugging them into the commander hub?

You don’t need to touch the CPU fan, that’s not connected to the case. Leave that as it was, that’s the AIO pump, you don’t adjust that from the BIOS

You just need to change the PWM header, if that’s for all the case fans plugged into it will address them all off that one header

From your picture, the two on the right are not fans, one is the power supply, the other is the PWM header to the motherboard, that's the only one you need to adjust.

The fans should all be connected on the ports to the left.

 

[jergil]

Further info: DC controlled fan speed does not seem to be functional at all. Tried increasing/decreasing the RPM of CHA_FAN5 and CPU_FAN but doesn't have any effect when applied (unless it only takes effect on saving and exiting BIOS?) PWM doesn't work either for obvious reasons. I'm fine with the rear fans being at around 930rpm but the front fans need to chill the f out!

Sidenote: 'iCUE detected that you are using DRAM modules with different types of profiles (EXPO and XMP) at the same time.... yada yada...Performance Manager tab is not available.'

Is this saying the my RAM sticks differ? Cos they should be the same. I'm not overly concerned but just wondering if you guys know what the deal is there?

Yeah I'm not touching those. I'm saying that the front fans are reported as being CPU fans and are stuck at 2.3krpm.

The CPU fans are currently at 579RPM as reported by iCUE

It's a known bug in iCue, it's a false report, it's basically saying you're using both XMP and EXPO to overclock the RAM which of course is nonsense.

Yes, it's not the front fans though, you can see what's plugged into CPU_Fan on the board, it's the AIO Pump, you can't control it from the BIOS, it's controlled via iCue, you don't adjust that.

 

[jergil]

Ahh, it's the pump... damn I thought that was it for sure. OK so back to what you said about switching the PWM header. Where do you suggest? I thought it was supposed to be in a SYS_FAN like CHA_FAN5, which is where it is now.

Ok thanks for this will ignore

 

[jergil]

Apologies for being a numpty, the AIO pump was on the list in the BIOS reading as N/A so I assumed iCUE was in charge of reporting that.

So... the plan to control the case fans through the case hub PWM connection to the mobo via the BIOS didn't pan out.

@SpyderTracks, you've suggested changing the PWM header but I'm not sure what you are proposing?

Sorry, I’m not following, it will work fine, but it’s not configured yet.

Im getting a bit lost as to where you’re at.

The case controller will only obviously control fans connected to it. You’ve said the front fans weren’t connected to it, you only showed half the controller in the picture you posted so we aren’t able to verify that.

If you don’t want to move the front fans onto headers onto the case controller, then you need to find out what port they’re connected into

Sorry I did actually say that the front fans are connected to the 3 pin headers on the case controller. I've posted a lot and sounds like you are really busy so no worries if you missed that bit.

So where we are is all 3 fans are connected to the nexus hub. The nexus hub is connected via the PWM header to the CHA_FAN5. Changing the CHA_FAN5 speed via the BIOS (or any other fan channel for that matter) doesn't have any effect in AUTO mode, DC mode or PWM mode. Turning the fans off doesn't turn them off either.
