No idea why it reports that temperature but I'm pretty certain that it isn't the temperature. If you look at the value as soon as you can after boot, it is already high and the value doesn't change much as the northbridge heats up.
I've had a digital thermometer stuck on the heatsink and the highest temperature I've recorded is just over 60C in a case with no fans. In a case with moderate extraction it gets to 50+C and now, in a case with a fan blowing down on the heatsink with air drawn through a grille in the case lid (view case
), it reaches low 40s Celsius under load.
I suppose it's not surprising that it's hot considering it's acting as a reasonable spec. graphics card.
Interestingly the temperature it reached was to some extent dependant on the software being used - I used the Blu Ray "Close Encounters" to do case/cooling checks before calling my HTPC built. With PowerDVD, CPU usage averaged around 55% (2400-BE) and a cooler NB, with Arcsoft Total Media Theatre CPU averaged 20-25% but a much warmer NB.
I've assumed that TMT was passing more of the decoding to the GPU, anyone know if this is possible (both using hardware acceleration, supposedly)?
In fact, in general what CPU usage do people get playing HD DVD/Blu Ray? All those glowing reviews I read before buying were talking of 20% or so but the first HD DVD I tried (Bourne Supremacy) averaged around 65% - which made me think I had something wrong - but I've used updated PowerDVD/graphics drivers and not seen a big improvement.
