i don't mind if its "noisy" if the result is a cool console... because Sony didn't do a good job in the first PS3 (the FAT with 90nm GPU) the result is YOLD cases. i had 2 YOLD and i would rather have more noise instead of a dead console. i really hope this 28mn APU has better thermal efficiency... i think it will have 90W TDP joined by the GDDR5 modules, a good heatsink paired with a silent fan can deal with this; but the fan control profile don't look like a aggressive one **... hope is enough.

**(temp 10 vs 60 minutes of operation, do they specify what type of operation we are talking about?)

the ylod problem was very low quality thermal grease and low quality lead-free solder

after some month to a year the thermal grease would start to deteriorate and the lead-free solder was losing viscosity faster than it should leading to irreversible damages at relatively low temperatures (the automatic system shut down was programmed for higher temperatures)

the cooling system itself of the PS3 was very good and after I exchanged the thermal grease to a high quality one it hardly ever was audible - I gave my launch PS3 to my brother though and switched to a model with half the power consumption

for those that are wondering... 0,83 sone is around 27,5 db...

that was not easy to find... strange Germans...

sound pressure hardly is a good method to show how loud sth is, as different frequencies are perceived way differently (individual differences in sound perception are existent, but small)

i know about the thermal grease and lead free solder "low quality", but as you might know, the more heat the more they deteriorate, both would held much better if the fan profile was more aggressive. My ps3 has a rebaled GPU, better thermal grease and i have a fan controller on my PS3, in the normal state the fan does not spin hard enough, the console get very hot, and if the exterior of the console gets that hot, imagine the heat sink, all that heat, does kill even the high quality thermal grease and leaded solder given the enough time. if Sony did compromise a little in the noise and build a little  more aggressive fan control profile, wouldn't fix the YOLD, but it wouldn't be this widespread...

about sone... se replay to walsufnir...
