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

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

Well I found that but I didn't understood... so I didn't share

So it's more quite then the slim model

That's bad isn't it? More than the PS3? I hate slow boot up times.

Isn't Xbone like 6-7 seconds to boot?

You realize that's cold boot right?, pretty much for the rest of the consoles connected-to-your-setup life would be booting from standby, which is near instant.

This is not strange, it's the superior way of saying how loud something is.

I cold boot mine every day.

anyway, 20 seconds start up doesnt make a difference to me.

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

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)

~30 seconds last time I read... this is the full boot... not the stand by feature that make you Instant Play.

What, Xbone takes 30 seconds from closed power to boot up OS? That's rotten.
