flash video overheat the cpu

[almusalimalmusalimah]

hello everyone

i have COREi3 CPU in my laptop and the critical temp is 89 ° C

if i try to watch HD flash video through firefox or any other browser

CPU temp will be at 78 ° C

so

is this a normal condition or what ?

[PiElle]

Whenever I watch a flash video tha fan starts spinning loudly.
This happens with all the Linux distributions I've used and with Windows 7 too (may be the latter runs a little bit cooler) ...

Which graphics driver and which graphics card, and is hardware acceleration enabled within flash player settings?
Apart from that, flash is really resource-hungry, even if it's for no good reason.

[almusalimalmusalimah]

the graphic driver is intel 810

yes the hardware acceleration in flash videos enabled

[doktor5000]

Your graphics chip does not support hardware accelerated rendering of flash, so it has to use the CPU. So yes for such a system that would be a normal condition. You could try to switch to HTML5 for youtube, f.ex. but otherwise you should complain to Adobe, not to us.

Question, is you CPU Fan running fast, or does it stay slow ?
Even with 100% usage, the CPU should not goes to 89° so easily in good condition.

(ok, it could be normal if you use AMD in a 35° room...)

[almusalimalmusalimah]

i hate adobe ..... this is so rude

in trashdos (( for me this is the second name for windows )) the temp will never ever cross even 67

even if you play any flash in 1080p

==================================================

and to make it worse

even if i play any video online without flash player (( i mean using HTML5 ))

the problem is the same

==================================================

or maybe this is a nasty bug in intel drivers or in kernel

==================================================

please .... we need any one to fix this nasty bug

[pmithrandir]

please, could you answer my question?

Doesn't matter if the fan runs slow or not, 89°C is a bit too much for something like that, in general.

But FWIW it wasn't even mentioned which Mageia version, browser and flash plugin version is used ... :/

[almusalimalmusalimah]

i have mageia 2

and the flash plugin in mageia is older (( the last version that adobe made it for linux )) ......

and the browser is firefox in both of them but mageia has the older one 10ESR while the other OS has 14

Doesn't matter if the fan runs slow or not, 89°C is a bit too much for something like that, in general.

I know there is some problem with fan speed in some circomptances (it's a bug I have since mandriva 2010 on my laptop... reported on bugs.mageia also since month /year ??)

Flash is one of the only application that really use the CPU... all others are stayiong around 20% on my laptop.
So, if the fan stay slow, you will never detect the increase of the temperature, except with flash.
I think it's relevant to ask if the fan speed is managed correctly by mageia, because a fan speed very slow would totally explain the 89°...
My laptop goes very often to 103° if I forget to do the trick to make the fan speed works.

[almusalimalmusalimah]

.............

fan speed has nothing to do with it

i cant tell you that its speed in windows is the same as in mageia

but from its sound i can recognize that both of them has the same speed

[pmithrandir]

k.

That mean that your computer is heating a lot at 100% of CPU(AMD maybe ?)
Regarding flash, I'm not sure it's even in adobe project to develop it for linux. I heard some times ago they wanted to stop devs.

I know there is a free version of flash(openflash ), you could unistall flash and install this one, but usually, the results are not better.
The probleme is more that your computer is a cheap one(like mine) with poor intel video card.

To get newer package, you could try to enable the backport on your computer. it would upgrade your firefox I think.(and maybe flash if there is an update)

[almusalimalmusalimah]

.............

as i said before

i have core i3 m330 and the critical temp is 89 ° C as sensors said

but as you said .... i will try to use gnash instead of adobe

if the results are the same then

where is that damn bug

[pmithrandir]

To explian...

Flash windows is using some hardware acceleration, that are not active on linux.
With a intel 810 video card, flash on linux is not able to understand that your card can actually do something, so he let the CPU manage everything.
that is "normal".
What is more strange, is that the temperature of your CPU goes at 89° when you use it a 100%. (it should stabilize around 75 max)

Some questions :
- if you use all your CPU under windows, what is your temperature(maybe it's the same)
- what is the temperature outside... you computer will heat more if it's 40° in the room you store it.

Some computer are better than others with cooling, but it's n,ot something easy to improve. If it's a too big issue, you can always goes in the bios, and remove the "cool and quiet" function. You fan will be always at the maximum speed, and you CPU will be less warm, but it's not something absolutely necessary.

-i dont know ..... but what i care about it here is flash-videos because in windows flash-video will never make CPU temp reach more than 67

but at linux the story is diffirent

-the temp in the room is 31 as maximum

[pmithrandir]

What I mean, is that you have to compare what is comparable.

try to find a software that will use 100% of your CPU for 10 minutes in windows, and check if the temperature is also a 89°.
If it's the case, that mean that you fan can't manage to get a lower temperature on your computer.

If the temperature is lower, that mean that your problem on linux is not only the CPU very high, but also the fan managed in a different way, and less efficient(it can be more efficient also)

In any case, flash works better on windows than on linux, so you can't excpect to make it works with your computer like on windows.

@pmithrandir: Please You mentioned things which are not true, there is nothing called "openflash" and also Flash player can use hardware acceleration on linux. Also your fan issues have nothing to do with his temperature problems, and for that comparison between linux and windows you're comparing apples against oranghes. Also, backports are still empty, not opened yet and hold no newer versions of firefox. Please just stop mangling together many issues together and putting half-knowledge into the mix. But as you already got started, feel free to finish to troubleshoot his issue.

EOT for me.
