A more personal experience would be the System76 Oryx Pro 2018. The back panel transfer the weight directly on the fans enclosure... And the weight of the laptop alone seams to be enough, with the heat, to djam the fans by squeezing them.
@Wolf480pl @ayo One other thing I hate about all those temps check and all is that the CPU max temps is way higher than the fans max temps before they start to deform and loose their effectiveness. Like... yeah they won't melt.. but they will get just flexible enough to change a little and start making noise or even djam. The 2018 Dell XPS series did that someone I know lately.
@ksteimel @ayo yeah. Most of the time the new gentoo users I help that have their computer can't stay open more than a minute have their fans deformed (or djam in their enclosure) and the thermal paste just not effective any more.. And practically all the time it's because of this intense usage that their machines aren't designed to support (Ex Windows) with a wrong config (Confusion about thread and CPU).
So yep it's not brick.. but it's close to. CPU is fine most of the time but meh ^^'
@ayo Well.. It "was" like that.. but most modern computer aren't design for that.. and it is annoying and sad.
@shiba @ayo Not relevant ^^' I'm talking about keeping using a thread at 100% for a while. Your example.. Doing 4 parallel compilation with 8 thread (4core/8 thread : average low end computer. I don't know your config) won't arm you because the system will natively auto swap threads to allow the cores to cold down. :) It's even less usage than recommanded by the gento wiki (cores + 1).
@r then your laptop must throttle it's cpu every time you do "big and intense install" (using all the "setted" thread for more than 2 minute). You should go even slower than If you had setted it to 5 to let the unused ones to cold down and then go full speed again ^^'.
And if you don't have any throttle then you have captor failure, didn't check kernel logs or a limit set to 100 degree ^^'
And if not I wanna know what is your cpu so I'll take that next time :P
@r Maybe I was unclear when I said "100% of a thread/cpu". What I meant was if you setup GCC too use near all the available thread. Like my CPU has 6 cpu and 2 thread by cpu. If I setup gcc like gento recommend it; I would have set a maximum of 7 parallel compiling. And I will be fine.
The problem is when new gentoo user set it to 11 in my example. They mistakenly think that every thread is a cpu. And here we go. Fans will deform and stop in their enclosures.
That was what my warning was about
@r It's true that those laptop have big problems with their "discrete gpu" for the cooling just to say that.
However, if you do like I said (using 100% of a thread for hours), you will get problem on any modern CPU.
This is why the "default" (or the recommended) way to setup GCC is to setup the maximum parallel compilations to the number of "real CPU". So the charge can be moved from one thread to an other to limit overheating and speed up the process.
@tuxcrafting @ayo Yeah my chromebook that I flashed on archlinux with the max98090 kernel ccan compile (really slowly.. arm..) for hours and nevers complain.. but it don't have the power to overheat...
I'm talking about any i7 8th gen or later on laptops. The gento wiki warn you about this in the gcc config in the installation help pages.
I had this problem on many laptop and some desktop. The solution is just to reduce the number of thread used by gcc to compile.
@r @ayo @r @ayo well, I'm talking about laptop for most of the case. A good example would be the latest Dell XPS. Or the system76 oryx pro.. Or the thinkpads from personal experiences. And the Gento wiki is warning you about that problem.
For desktop.. my experience stop at the dell and asus latest; they have this problem too.
So.. I guess you can keep your idea about this until it happen to you too ^^' not here to argue about this fact :)
@ayo Friendly warning: Most of the modern computer aren't designed to sustain a "100% thread/cpu" for more than 3-4 minutes. And most of those new computers have their temperatures limits way too high. And since the kernel start to throttle when it's already too late most of the time; You may brick your system or more likely damage the cooling system just by using Gento and compiling with most of the available thread with GCC ^^'
@salixlucida It is indeed slow. But for the area where I am right now, it is more than enough :) (Europe, where the 4g is the slowest I ever saw... But the cheapest. Unlimited data for 20 euro/month, I can't complain)
@mnw Thanks for the discovery. I'll try that on my beagle bone soon :)
I need some help.
I know nothing about hardware and need a new workstation (not a laptop).
Use cases are
- must support OpenBSD
- building an OpenBSD release as fast as possible
- run some VMM vms
- run a browser
- fit on desk (uATX?)
serial console and wake on lan would be neat.
I'm thinking Ryzen 7 3800X, 64GB RAM, nvme, passively cooled radeon(4) graphics card.
Looking for a list of all needed components, thanks!
@salixlucida Thks. I'll look into that one.
