if it isn't as efficient then it's their problem.
For sure, but to be fair according to me it has to be compared to similar products.
the temps show that the nb temps are about the same, the dfi is about 10C higher in sb temps, and a massive 17C higher in vrm temps.
It may worth to give a look to the more similar (as for form factor AND
price) M4A78-HTPC/RC: SB temp is 53Â°C (-7Â°C), NB temp is 66Â°C (-20Â°C), VRM's temp seem to be identical (or nearby: even the VRM seem identical, a 4+1 if I'm correct).
now the similar nb temps suggest that the positioning hasn't increased its temperature
With respect with the above quoted data, it should seem that the different positioning may affect NB's temp, even if the HD 3300 is more powerful than HD 3200.
the vrm temps however, can be explained by the different heatsinks used, and the design of the power circuitry- both things are directly chosen/designed/engineered by dfi.
And/or super imposed by the form factor, I guess.
Yes, size matters: heat dissipation is in direct ratio to physical dimensions, isn't it? And so, for some respects, the power efficiency.
for heatsinks yes, but for motherboards i'm still not that convinced.
Well, as said, the law of physics can't be overtaken by human will: the ÂµATX form factor has more thermal limitations than the ATX (a smaller surface is able to dissipate less heat than a larger one, and this is a fact, a smaller surface may host less chip than a larger one, and so on).
the smaller size simply isn't a good enough excuse for me.
The smaller size isn't an accident (or an excuse): it's a capital point of the whole project. This is my point: apples to apples, ÂµATX to ÂµATX.
If in case then you may discuss if the choice of Crossfire on a ÂµATX motherboard is savvy or not.
But anyway, I have not to convince anyone of some evidences: if you (or MikeC) don't like that mobo, it won't be a problem.
