 Hi everyone.

I read on a 2011 article - http://www.phoronix.com/scan.php?page=article&item=nouveau_comp_2011&num=19 - that my particular card, GeForce 8400 GS, overheats with nouveau. (So, I never tried using if for long, before, as soon as possible, installing the proprietary drivers...) But, because it's a 2-year-old article, I was wondering if that problem could have been, in the meantime, solved?... (Can anyone tell me if that is so, or not - or indicate me a place where I can know that?)

Thank you, all, in advance.

There are actually several versions of the 8400 GS, the exact chipset
would be a better indicator (if you're trying to compare to Phoronix
results). It seems like the complaint in the article was that the
passively cooled GPU was running at 80 degC. While that's quite warm,
I'm pretty sure that's not nearly enough to be damaging. I had run my
9500GT (which started out with a fan that I later removed) at 90-95
degC with no apparent ill effect.

If you do have a fan, there is some semblance of control in the latest
kernels. Take a look at
http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/Documentation/thermal/nouveau_thermal
for more details. There is also experimental reclocking support for
the nv50 family chipsets (as well as nv40), which tends to be very
much hit or miss. Works great when it works, but hangs the card when
it doesn't. Take a look at
http://nouveau.freedesktop.org/wiki/KernelModuleParameters/,
specifically perflvl_wr. Note that this only provides manual control,
not dynamic like the latest radeon and nvidia proprietary drivers.

Hope this helps,

Hi Fernando,

The idea of overheating is quite subjective and heavily depends on how
sane the OEM was. But to put a long story short

1. Nouveau does not change the clock frequencies and voltage (among a
few others) which may cause higher than desired temperature for some users.
2. Thermal management has been available for a while now although it's
disabled by default. You would need to enable it manually see [1] [2]

I would personally give nouveau a try if I was in your case and check
the temperature via (lm_)sensors.

Hope that helps,
Emil

That situation likely hasn't changed as far as I know. But I think that 
article was overreacting. 80 degrees C on an NVIDIA GPU really should 
not be dangerous. There are GPUs that can normally hit over 100 degrees 
even with active cooling. Passively cooled GPUs like that will normally 
run pretty warm.
