CPU Fan speeds going very fast at random

Hi there,

I am just wondering what is the correct process for logging a bug in Beta releases.

AFAIK Fedora 36 is still technically in Beta and I am getting some odd issues,

I am unsure if I am permitted to log a bug here


I am at this page:

but I know ordinarily bugs are reported with this process here:

But I beleive thats for stable releases.

Since I am not an engineer on the Fedora team I dont think I have the authority to log bugs as beta blockers right?


The bug filing process is for all supported Fedora releases and releases in development (rawhide and beta etc.)—so you should certainly file a bug.

The app in the screenshot is for proposing “blocker bugs”, i.e., bugs that are severe enough to need fixing in order for a beta release to be considered for stable release. So, once you file your bug, if you believe it should be a release blocker, you use this app to submit your bug for consideration. The QA and release engineering teams will then review your bug to decide what should be done—whether it should block the release based on the release criteria that is set out, or if it can be fixed as an update later in the release cycle and so on.

Edit: more information on the blocker bugs process here in the SOP (standard operating procedure):



Thank you kindly Ankur very much for clarifying, I logged a bug in the correct area.

I will try to log this bug in the beta blocker area too as I have heard in the fedora IRC chats on matrix that others have similar issues but have not reported them.

In your opinion would this bug

be considered “freeze exception” category since its quite serious as my fans sometimes get stuck on.

I dont want to hold up the beta from being released :face_with_hand_over_mouth: but I know others who have this issue,

Your bug is marked as “private”, so we won’t be able to see it. Please change it to “public”, otherwise it can’t be looked at.

If not yet done, please also state which unmet Release Criterion makes this bug a Blocker bug.

FAQ on hardware-specific bugs: https://fedoraproject.org/wiki/Blocker_Bug_FAQ#What_about_hardware_and_local_configuration_dependent_issues.3F


Did you check whether temperatures are rising and there is a good reason for the fan to spin up?

watch -n 2 sensors

also, it would be important which fan is spinning up. (sensors will show you).

Another hint, review your the bug severity, this bug is certainly not urgent (advise: just leave it unspecified): Bug Fields

You should include information about the hardware you’re running please and thanks.


Okay thanks I didn’t know it was set that way, i’m looking in there and cannot see how to change the setting from private to non private.

Yes I linked the bug that I reported to the neofetch output it should be showing,

There should be a link in there. I will try to edit that now thanks

the bug report has been made public already: https://pagure.io/fedora-qa/blocker-review/issue/799#comment-795142

Comment 3 of the bug report says what outputs are requested. Quoting kparal in https://bugzilla.redhat.com/show_bug.cgi?id=2080720#c3

lspci -nn and lscpu | grep 'Model name'. When this fan issue occurs, save a system journal by journalctl -b > journal.txt and upload it here.

I tried to upload the journalctl text file though it says only image files can be uploaded...:frowning: 

How do we upload text files here in the chat

Please add / upload the information to the bug tracker, that’s where the bug is triaged and the information was requested.

.txt can be uploaded as attachment there.

Independent of the bug not being a release blocker, it’s still worth investigating and fixing the issue.

I have heard from @kparal and he mentions it is a GPU issue for RADEON video cards.

Can I asked would this issue go away if I rolled back the kernel to an older release? The fans are very noisy when it happens.

He suggests a seperate bug should be created as it seems to be a GPU power management issue.

I have uploaded the journalctl in there it should be there now

I have taken the case off the PC box and checked and it is indeed the video card making all the noise.


I understood that he suggested to file the resume error as a separate bug (“I believe resume failure will be a different problem than the fan issue, so a separate bug should probably be created.”)

Didn’t see it.


Hmm it should be there now.

I just re uploaded it.

I also am running sensors now after installing it I will try to see what happens. Problem is it only happens when the screen goes blank or the screen locks.

Can you please provide some more information, it is hard to understand what is happening and what you are doing - please understand that we cannot see/hear your system so you need to be very descriptive.

  1. Starting off, your bug report says it’s the CPU fan, but “possibly GPU fans I need to verify this”. Have you verified which of these fans it is exactly? If so, please update the bug report with that relevant information.

  2. Your report has some conflicting infomation. Can you please be more clear on the order of the events - does the fan go to full speed right after the screen goes off? After the system suspends? After the system wakes from suspends? After the screen is turned back on by the system?

  • “when I let the system lock and screen turn off, the CPU fan turns on full noise” - is it right after screen off?
  • “When the screen starts to get back the CPU/GPU fans go into full speed mode” - or is it right after system is woken?
  1. Please help us read your journal log.
  • How did you collect the log? E.g. - Wait until system turns off monitor, hear fans speed up, wake up screen, open terminal and run journal -b > journal.txt?
  • Can you tell us the timestamp of when the fans sped up? If not, next time use a watch/phone to note the time that the fans speed up. That way we can correlate the time to the timestamps in the journal file.
    As of now, it’s too hard to know where in the log file we should look if we don’t have a timestamp and don’t know the sequence of events that occurred.

That being said, it looks like there was a coredump near the end of the journal. But without knowing the timeline of events, it’s hard to know whether it’s related or not.

I’ve changed the title of this thread to better describe the problem.

okay forgive my ignorance.

  1. First I have confirmed as earlier noted it is indeed the GPU fans not CPU fans. I will amend this in the logged bug report.

  2. Yes correct the fan goes to full speed right after the screen goes black @kparal mentions the same issue in the bug report as a comment. Apparently this was a bug with Radeon GPU’s. It also goes to full speed right after the screen locks or screen goes to sleep.

  3. Correct I waited untill the system turns off monitor, hear fansspeed up, then I woke up the screen and ran the command journal -b > journal.txt

the journal timestamp was the exact moment it happened was when the last occurance happened. I.e it should be the last thing in the log I would presume.

I thought I mentioned that,. I will change that.
