[opensuse] cpu heat
Hello, On my main laptop, I find the cpu is getting hot very fast My desk is climatized, temperature is not cold but not hot either (around 27°C) at rest the cpu temp is around 60° a simple copy from a disk to an other makes it go up to 85°C, and dmesg gives red warning cpu speed is reduced.

I have a fan-less mini server that does this under load. If it gets too hot it slows down till it cools down. It stays responsive all the time. It is normal behaviour for that machine. So I slow down the tasks I give it to do. Yours has a fan, so it seems that the fan + CPU sink assembly is not responding right. Sensors say it is doing 4500 RPM. First thing to look for is dust. The other two are conductive paste or gas leak, if it is one of those filled with gas. -- Cheers / Saludos, Carlos E. R. (from 15.1 x86_64 at Telcontar)

Yes, at these temperatures and assuming everything else is OK, the fan should be blowing out "fire" ;) If the air is not very hot, then something is blocked or something is not attached properly. Anyway, this is definitely a hardware issue that can only be solved with some tools and physical examination. The good news is that your computer is still working, so it's only a cooling issue.

The cpu fan was my first thought too. You mention dust. You might take a look at the cpu heat sink, I've seen them become totally blocked with dust. I wouldn't remove the heat sink to redo the thermal grease, there's always the possibility of screwing something else up when you go that deep.

Technical term: "Dust Bunnies", contributing factors include large desktop environment demands on the CPU. Two separate issues: (1) if there is any dust build-up in the cooling paths within your laptop, you will see temp spikes under any load. The cure is to clean them out (BUT YOU MUST TAKE CARE NOT TO OVERSPEED YOUR FANS IN THE PROCESS) If you can't open your laptop (most cannot), then your best friend is a shop-vac (with a brush attachment to brush over the screens to help pull the dust bunnies through the small screen holes). BEFORE you just take the shop-vac crevice nozzle to the openings in your laptop - find out where the fan is (sometimes you can see it right behind one of the cooling screens) You want to "peg-the-fan" to prevent it from spinning. (you hit it with the shop vac and you can easily send it spinning 10X its limit and potentially cause it to fly apart) so use a thumb-tack or small piece of wire (20 ga. or so) to slip though the screen and secure the fan blade from moving) Then you can shop-vac with the crevice tool to your hearts content and see all the dead rats pile up against the cooling screens on the inside (use small circular motions with the brush attachment to pull the cruft through the screen a few bits at a time) If you can't peg-the-fan, then the shop vac is still your friend, but you can't just put the nozzle over the screen. Instead use the brush attachment and wand it over the cooling screen in short sweeps to prevent putting the full force of the vacuum through the cooling path. If you have no brush attachment, then you can spread your fingers over the end of your vacuum hose to keep the nozzle directly off the cooling screen and do the same thing (without a brush attachment, you will need a brush of some kind, old toothbrush, scrub brush with fine bristles to help pull the dust bunnies through the screen) (2) Plasma and Gnome -- they are CPU hogs no matter how you slice it. I just did my bi-monthly update of Plasma from Git (kde app versions 20.04) and my laptop sounded like an airplane. Plasma would settle down and idle just fine with no inputs, but as soon as you started to do anything (mouse movements, etc.., simple editors kwrite, kate, or even konsole) the temps would spike and the fans would switch to take-off speed (with an i7 and 8G of RAM) So even clean, with a heavy desktop, laptops are going to struggle that is just a fact. Laptops lack by an order of magnitude the cooling capacity of desktop computers (a desktop CPU cooler is generally 2-3 times a thick as a laptop to begin with unless it is liquid cooled and then we are in a whole different area of cooling not available to laptops anyway) ======== So those are the two things and approaches I know to help with CPU heat problems. The dust-bunnie issues should be an every couple of month maintenance thing anyway (though I'm human too and don't always get a round to it). The desktop environment issue is just how much CPU the varying desktops demand. Plasma and Gnome have been designed to do all that can be done to utilize the CPU to provide all the niceties that the desktops provide. Which is fine for desktops with all the cooling in the world, but is horrible for laptops that are a couple of years old. Yes, you can tediously pick through the default settings and try and turn unnecessary processes off -- but that gets beyond the ability of many users (do I need this process, or can I turn it off?) I turn off everything non-necessary for my desktop, and even then Plasma smokes the fans on my 5 year old laptop. So unless you need desktop effects, fading windows, fonts that auto-size for your windows, etc... you may want to consider a different desktop. I run KDE3 for that purpose. I also keep Fluxbox and I3 installed. All of which can load on top of Linux and run happily in less than 200M of memory. XFCE and LxQt are also good lightweight desktop environments that are currently supported. I haven't messed with Deepin, Mate or Cinnamon, etc.. so I can't comment on there CPU demand, but you need to size your desktop to what your hardware can handle. So longer than I initially intended, but hopefully it provides some options -- David C.

I opened the computer one hour ago. It's really needed, cleaning without opening is dangerous as you said, and may send dust in odd places. It was not so much dusty, but the fan blade where dusty and this may have slowed down air flow. Fixed now. I didn't touch the heat pipe, if it was this the cpu would have shut down faster. I also add a plasmoid in my screen (kde) to have fan speed and temperature in sight :-) (59°C right now, but no big load, my video work is finished :-)
(BUT YOU MUST TAKE CARE NOT TO OVERSPEED YOUR FANS IN THE PROCESS)
sure. Be gentle with the house vacuum cleaner :-). I use mostly a brush.
You want to "peg-the-fan" to prevent it from spinning. (you hit it with the shop vac
I only test the fan by blowing in the exaust to see if the blade do they job (ok) and you can easily send it spinning 10X its limit and potentially
cause it to fly apart)
don't be a brute :-))
So those are the two things and approaches I know to help with CPU heat problems. The dust-bunnie issues should be an every couple of month maintenance thing anyway
my desk is not overly cleaned and the computer can spend a year between two cleanings (it's the first time I notice a overheating), but I've seen long time ago a room filled of used computers sent for refurbishing and *full* of dust as much as the vacum bag!! incredible. Of course nobody wanted to touch them :-))
is fine for desktops with all the cooling in the world, but is horrible for laptops that are a couple of years old.
honestly, I don't have computers newer than 5 years old, and kde works like a charm. Much better than previous kde incarnations, even on 10 years old computers. fact is, I can try to use icewm (the openSUSE rescue system) when doing heavy work, but I wonder if it's really better as I use kdenlive, dolphin or digikam. I will go from 15.1 to 15.2 pretty soon, my plasmashell is severely broken, the taskbar become unresponsive ever few minutes, but I need a fresh install, so need time :-(
I can't comment on there CPU demand, but you need to size your desktop to what your hardware can handle.
you know, I bough this computer second hand, but nearly new, 3 years ago. I just scanned the net to find if I could find a better one for less than $1000 and didn't... I have 15Gb memory, i7, 500Gb ssd. I will just change the secondary hdd (in dvd caddy) for a 1Tb ssd and voilà, I hope for at least two more years.
So longer than I initially intended, but hopefully it provides some options

Sounds like my laptop (I only have 8G, with NVidia Quadro card), 17 inch screen, dual HDD bays with a 3rd drive bay if I remove the DVD. There is nothing wrong with old hardware.

be cautious not to over charge your processor. some things are curious. My cpu is said (lscpu) to be 2.4HHz, but cpupower frequency-info gives 0.8-3.5. With 2.4, the cpu do not heat.

To me, this indicates a kernel problem or bug somewhere. The kernel should be able to automatically slow down the CPU when it overheats, keeping the machine fully responsive and within temp margins. I have a small fan-less server that does this fine, I see the entries in the log. I also have a fan-less laptop where I have not noticed the behaviour, but should be there.

it does, but keep the cpu around 95°C, wich I found too hot (max is 100°C) best is a way to drive the cpu according to temperature.

Sure, but you lower temperature lowering the frequency, or the cpu cycles used by your script.
I don't play games, so no need to overclock the cpu. My cpu is given for 2.4GHz, why put it faster?
# "cpupower frequency-set -u 2.6G" make fan go max 3900 rpm and temp 85°C, perfect
Sure, I'm just noting alternatives. -- Cheers / Saludos, Carlos E. R. (from 15.1 x86_64 at Telcontar)

Well, rsyncd, obviously, in this example. See the command I wrote above.
yes, but wich one for handbrake? thanks jdd -- http://dodin.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

It is not a service controlled by systemd, so no, you can not apply that method. It is either cpupower as you did, slowing the entire system, or cpulimit, slowing only your script, bit with the danger of some other process filling the CPU and heating it up again. -- Cheers / Saludos, Carlos E.

I found a solution
Has anyone mentioned cleaning the fan? I have seen a computer slow down and even turn off when too hot. Cleaning the fan fixed the problem. Years ago, when I was a computer tech maintaining mini computers, cleaning the fan and air filters was part of the routine maintenance. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

yes, it was the first solution, and I did it, but without much difference I could also change the thermal grease, but I'm reluctant to unmount the thermal pipes :-( jdd -- http://dodin.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Save this as your last resort -- but -- I have had good success replacing the thermal grease on old boxes showing heating issues (I prefer Arctic Silver 5) I generally (gently) pull everything apart, and then take an old single-edge flat razor blade and (carefully) scrape the majority of the old grease off the processor (you are not trying to clean it all, just remove the bulk of it). Then I'll use a old rag and WD-40 to remove the remainder of the thermal compound and give it a couple of minutes to dry. (if I didn't have WD-40, I'd probably use 409 or another kitchen cleaner that is a dilute petroleum distillate) I've used this method on everything from 386 on without problem. Apply the new thermal grease (sparingly). You simply want as thin a physical seal between the processor and heat-sink as possible. (if both the processor top and heat-sink base were perfectly flat -- you wouldn't need any thermal compound) Thermal grease/compound, regardless of what it is, is an (insulator) with metals added to help conduct heat, you want as little as possible (once the heat-sink spring clamps are on, you can give it a few small rotational wiggles to help make sure the thermal grease spreads thinly) Then I usually use a wooden toothpick to remove any excess compound that squeezes out. Generally speaking after about 5+ years, the old compound has probably gone though enough heating/cooling cycles (as well as off-gassing any of the nasty stuff it was made of) to make it less efficient at transferring heat. Try regulating the CPU speed first, but if all else fails, a $7.00 tube of Arctic Silver 5 will provide enough for 10 or so machines. -- David C.

I have just ordered some new one (the old one I have is too old and I don't remember how much I have available - I don't want to be stuck in the middle of the operation :-). but it's just in case. I never had to do so on laptops before (I did on desktop mobo). However, I notice this one is specially hot, being at 54°C when iddle when I tracked yesterday a faulty desktop mobo that was only 40°C hot :-( - but refreshing a laptop is much more difficult, and this one have the exhaust just under the screen hinge, so what I can't easily add an extractor :-( thanks jdd -- http://dodin.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Yes, you can tediously pick through the default settings and try and turn unnecessary processes off -- but that gets beyond the ability of many users (do I need this process, or can I turn it off?) I turn off everything non-necessary for my desktop, and even then Plasma smokes the fans on my 5 year old laptop. So unless you need desktop effects, fading windows, fonts that auto-size for your windows, etc... you may want to consider a different desktop.
My guess is that if you remove small processes, the main process will simply use the full remaining power, so no gain. Instead, you can use tools like cpulimit to limit the cpu power of the main process. If it is a daemon, systemd can help. -- Cheers / Saludos, Carlos E. R. (from 15.1 x86_64 at Telcontar)
