Just booted on a 3950x for the first time, fans randomly triggered making noise (NO OC)

[MS-DOS]

The nightmare has been confirmed.. I remember reading this and its happening to me. Im using Noctua 15 chromax black with x3 Silent Wings High Speed 120mm at the front and x1 Silent Wings High Speed 140mm as exhaust on the rear. Case is Define R6. Other specs:

 

MOBO: Aorus Pro x570

RAM: 16x2gb Tridentz Neo

PSU: Corsair rm750x

Storage: Samsung Evo Plus 970

GPU: Radeon HD 7850 (waiting for new nVidias...)

 

OS is Windows 10 Enterprise LTSC, i've updated it and so on. Drivers are installed....

 

On the BIOS (or I think as its called now, UEFI) the fan curves are set to the default normal ones for everything.

 

I've connected the CPU fan to CPU_FAN, the rear fan to SYS_FAN2, and the 3-fan PWM panel hub thing on the R6 on CPU_OPT. All fans are spinning, and respond to configuration since I tested "full speed" on all.

 

So it seems what i've read is true: The 3950x spikes temp randomly, even during doing mundane shit like browsing the internet or scrolling up and down and so on, this is rather ridiculous. There has to be a way to get rid of the random fans going boing747 mode, its not like im playing Doom Eternal, im literally watching videos, or scrolling a webpage etc.

 

I took screenshots of the whole sensors list on hwinfo, hopefully it helps:

 

 

Do you see anything odd?

 

Are the temps ok? voltages?

 

Something must be triggering the fans. Im not sure if its only the Noctua nh d15 being triggered or the front fans too... they make a characteristic noise past a certain rpm. Like a plane or when you have a window with a small gap and wind is being pushed throught the gap.. do you know what I mean? Point is, its getting on my nerves.

By lookin at the speeds.. im not sure because I don't know what reasonable speeds are given those fans, but perhaps 1200 rpm average on the 3 front fans (CPU_OPT)

 

But seeing that the CPU_FAN hit a peak of 1117 rpm is just nonsense. Max speed on the Noctua nh d15 is 1500... that's almost there for doing nothing on youtube and having some tabs opened on firefox. May have been triggered by that 51ºC peak, which now i've hit a peak of 56Cº moving windows around and scrolling up and down fast... quite disappointing. I was told some dude was able to get this set to almost near silent during mundane usage (internet browsing etc) so I hope there is a solution.

 

I've noticed the clocks jump around, from 2,15 ish to 2,90 ish (im looking at the real time Windows 10 manager thing, ctrl+alt+del Window). Please notice my previous build was 10 years old and had a clock that never moved (it was a q6600) so this is all to me. I was on Win 7 as well.. so yeah, this is an huge jump, and its disapointing to see that doing nothing is triggering the temp and thus the fans.. geeez.

Fans get triggered when im on paint. This is ridiculous.

How hot does it get in stress test? Just to know whether it's due to bad cooler mount or high stock voltage, latter can be solved with a negative voltage offset.

I haven't tried any tests yet since its already derping with the fans with firefox... should I run cinebench for a minute or something?

I'm thinking of full on Prime95, though Cinebench in loop could be a good start

Ok I will test now. BTW can I tweak fan curves without having to be on the UEFI? (and set them at UEFI level not depending on the software used)

I cant use this without creating account? they asking me to sign up or something

Yeah I meant Cinebench. Anyway.. will try tomorrow.. don't want to wake up neighbours with the fans

Fan curve can only be set in BIOS

Cinebench R20? Yes it's now in the Microsoft store. you can still download R15 and use that

If you find the fans ramping up on light tasks just set the lowest temperature higher. I'm on a 3900x, but its not that much different. I have quiet fans up 58C so things are quiete during light tasks. 

[madaaron]

I am running a 3950x and have some ramp up of fans but nothing like you are experiencing. Im on a noctua d15 and its so quiet even when it does ramp up. I dont know much about your bios but i know in my MSI I had to set the fans to pwm and they got even quieter, they were defaulted to voltage control. They never got real loud but I guess they followed with the issue you have, I am running noctua case fans so I guess that may be why they are so quiet.

I would do as alyen says and set low end temps higher

[Xkillerpn]

You can use Speedfan to ajust any fan on your system if you dont have a software for that.

 

But 60c on that cpu is actualy ok. even 80c

Yeah but you can also use this:

 

 

But i've adjusted a curve in UEFI that basically stays at 50% unless it hits 60Cº then it starts ramping up, i've set 80Cº and now it seems its decently quiet but its not at night now so i dont notice noises as much. Im going to go and put all the fans on PWM modere as @madaaron suggested since they are all set at auto so just to be sure. What temperature Interval you guys use?

 

Also, I remember reading someone made a custom power management profile that improved things but I can't remember, anyone knows??

You can still download R20 from maxon directly if you would prefer it over prime95, they just made it easier for most people that dont mind being spied on by M$

My experience is these software tend to not work as intended (e.g. failing to apply on boot), I'm forced to use it on my Z77 system because back then, fan speed to temperature graphs isn't a thing yet and the level system is pretty dumb as it keeps on blasting the fans way too aggressively. You can change how early or late it does that with target temperature, but that's it.

 

1usmus's power plan?

[Columbo]

16 Cores. Don't forget that. It requires a lot of cooling power. People forget this. Even temps @ 80C under load are normal and fine.

Yeah im going to stick to UEFI as the master fan curve thing for everything. I really like the "System Information Viewer" GUI but I don't want software fighting against the UEFI and overriding each other fan curves or something.

 

What im trying to understand now is, where are the sensors located? According to this, there is a sensor on the lower left and another on the lower right:

 

 

"System 1" and "System 2" are the same place (red spot) and "System 4" is near the frontal fans. Should I use this as reference for the frontal fans? Right now it's using CPU temp as reference, this may be making them spike. The R6 fan hub for the 3 frontal fans is plugged at CPU_OPT and this board allows you to use other sensors (not just CPU). This is the drop down menu for CPU_OPT:

 

 

Which of those makes sense to use? Here's the different sensor temps:

 

 

I don't understand. Which of those is located at the front near the 3 fans as seen on "System 4" on the SIV software? There's only System 1 and System 2 and the way I understood from that software showing the red dot is that they are the same sensor but there isn't the same temps there.. and there is no System 4.

 

So could you tell me what sensor should I choose for the 3 frontal fans? and for the rear fan?

 

If needed, I can unplug the fan hub out of CPU_OPT and get it somewhere else to get System 2 as reference, but again, I don't even know where those are located.

I don't care about noise while im actually using it, but there's no excuse to have a silent system while doing mundane stuff, there has to be a sweet spot. CPU usage on Windows (ctrl alt del thing) is literally 1 to 2% all the time.

The lower left corner seems to be talking about different fan headers, not sensor

This looks like the sensors. CPU means CPU max core temp (I think) or socket temp, EC_Temp1 is the reading of themal probe you can attach to the board, PCIe x16 is a sensor on the top PCIe slot (meant for M.2 SSD I guess?), VRM MOS for VRM temperature.

Sorry to maybe reopen by posting this but i feel alot of people have  of people like myself have the same issue just recently purchased one but i did some did internet searching came to a few conclusions and this can be noted from buying one recently and wanting to share how to sort out the fan curve issue that where everything tried doesn't work , one its not your Bios or fan curve setting so Now this is all on Microsoft and AMD as their profile for power on windows is missed up

 

Okay i recently bought and built :

Windows 10 Pro 64-bit (10.0, Build 18363) (18362.19h1_release.190318-1202)
System Model: X570 AORUS PRO
BIOS: F20a (type: UEFI)
Processor: AMD Ryzen 9 3950X 16-Core Processor  (32 CPUs), ~3.5GHz
Memory: 32GB RAM 8GB x 4 Corsair LPX

PSU : 1000w Huntkey

Graphic Card :MSI Duke 2080

 

 

 

,i have a custom air cooler with 12 heat pipes ,that has additional cooling from a pieltier chip that assists the cooling now all in all i now this cooler should work as because tested on a thread ripper  it kept it nice and chilled ,i followed hardwarecanucks advise on bios settings sorta worked then a new agiesa update came in for the mobo and bam the fan ramped up and down just opening or loading a web page or paint even refreshing a page was ramping them ,noticed that when i was in Linux i didn't experience this,or if i used my Ryzen 7 1700 at a high clocking so decided to look for a solution as it seemed software more then hardware

 

finally found a a youtube channel video called AMD Ryzen loud CPU fan noise fix (stock Wraith Prism cooler)

by the channel Mr. Sujano about F______  windows being the cause can't believe windows was the F______ cause of-course i should have known windows would screw me like this , anyhow long story short go-to you power plan in windows ,go-to advanced settings ,Processor power management option,open the drop down set minimum state of processor to 99% on minimum and maximum and boom windows doesn't ramp the speeds up and hell the chip dropped from idle of 42'c to 33'c, even the voltages seem more stable when monitoring them after this is applied and why would 1 % change this or any change in those figures change the fans so i am assuming it is something like the memory leak that was in windows 7 for some users ,where large chucks of memory was just used by windows apps that actually require nothing more then 80mb,now in normal use  now the processor doesn't shit itself like before and be like i need to be cool when windows does anything like ramping fans

 

hope that help you guyz that are having this issue please share this fix for anyone else suffering from bloody ears caused by fan noise

out it surely made my Day Thanks to Mr. Sujano ,solved my horrid experience of multiple fans ramping

AMD and Microsoft need to fix this as when you do this fix you can clearly see that temps drop and activity from windows to CPU drops , this seems to be a known thing to a few but yeah if someone can throw some pressure on them to correct this issue

 

 

Please note  one small down side i noted you do take a small hit in  Performance,but nothing to much to worry about you can regain with overclocking or tweaking the bios though the ownness \ responsibility falls on you to do so and do so carefully as one never knows how reads this,i'm just sharing a setting i found that  actually works with all AMD systems affected by this had 15 builds for clientele did the same thing and they were happy for a the small loss for the fans to quieten down and a small hit in  Performance is better then those ramping fans especially when your editing or making content the relief from the noise is bliss, the fans will go up when usage is high then slower deramps as the CPU cools down hell even the CPU operated quieter and cooler thanks to this seems to work as a pc should
