I don't know. I assume it's an on-die heat sensor. AFAIK, most modern 
CPUs have them, so that they can turn up the fan speed or go into lower 
power states if the die temperature gets too high...

OK, I was just playing TF2 and noticed a few stray polygons. (I.e., the 
driver update hasn't fixed this.) When I quit the game, I opened up the 


Next time I play TF2, I must remember to open the monitor *first*. ;-)

I wonder why it gets so much hotter running a real game (which is 
optimised to run smoothly) than running a stress test (which is designed 
to use up as much GPU resources as possible)...

Can't you play TF2 in windowed mode?  Or download some game demo that can be 
played in windowed mode.

I guess the stress test wasn't written very well, or without the knowledge 
of your particular card.  Lots of things in the GPU can be the bottleneck, a 
well-written stress test should work this out and adjust the test details so 
that every part is almost at maximum throughput.  If it's not very well 
written, then - for example - the vertex shader might be loaded at 100% 
while the pixel shader and texture lookup units are sitting idle for 90% of 
the time.

BTW what is the CPU load during the stress test and TF2?  Maybe that is 
affecting the GPU temperatures?

I guess I could - but it would be very hard to play it and enjoy it.

FWIW, last time I played, I did remember to start up the monitor. I've 

Which sounds pretty damned hot to me, but hey...

Given that it's an nVidia GPU running a stress test written by nVidia, 
you'd think so. ;-)

AMD Athlon64 X2 4200+ socket 939.

(When I built the system, everybody said that socket 939 was going to be 
the future. Now it appears that actually it's AM2... oh well!)

That's the CPU model; and the load while playing the game? :)

I meant just so you could see the temperatures while playing.

Yes, and a lot of people were p***ed off about that...

AMD claim to have learned their lesson there. Certainly the new AM2+ 
chips all work in socket AM2 motherboards (although obviously not as 
well as they could do).

But then, I heard people saying things like "this could be the end for 
AMD" (referring to the way Phenom pales in comparison to Core 2).

I doubt it.  A company the size of AMD doesn't just disappear overnight, 
no matter how hard times are.

They've got time to get their act together.

Heh. I guess "oh noes, this is teh endzors!" just makes better headlines 
or something. ;-)

They just bought ATi, so they can't be doing that badly. (Or, 
alternatively, ATi were doing *really* badly!)

That put me in a bit of a spot. I always buy AMD CPUs, and I always guy 
nVidia GPUs. So AMD buying ATi was a problem. Of course, currently AMD 
is nowhere in terms of CPU performance, so if I were to upgrade sometime 
soon, I'd have to go with Intel...

(Now and then I get these crazy ideas that I might buy a Mac or 
something... This usually wears off when I look at the price list.)
