What i cant hear you ps4 to loud!!!!! lol so im going to assume that its good and give a gj to sony

I never really had a problem with the noise of the PS3. However, when I turned off the TV and everything else in the house was quiet, then I could hear it.

The weight is decent, similar to my laptop.

i read a little bit about it in my "quest" to find the result in db's, and many web pages did the same statment as you, that is why i said strange. it is strange for me, and i guess for most of us, even if its better...
live and learn.

The thing is many people have a problem to read understand logarithmic scale and sone solves this with a linear approach to represend loudness.

The problem with db is that double the amount of db doesn't mean it's twice as loud. That's why it's kinda hard to compare. With Sone it's easier. Something with 2 Sone is twice as loud as something with 1 Sone.

In reality, it's a little more complicated of course (talk about perceived noise and stuff), but that's what it all comes down to and why db gets used less and less.

edit: Oh damn, too slow. :P

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...

yes... i understand what makes Sone scale a better scale... no doubt here. what i meant is a cultural thing... i can make in my mind a "image" of what is 300 kilometers, 200 grams of sugar and how much is 150 horse power but i have some difficulty (some are even impossible) to image whats 100 miles, 30 onces of sugar and how much is 136 kW... get it... we are used to use some measures scales and its strange and hard to get used to others, even, like in this case, if the scale is better.
