Gansta those points you made aren' t very valid. Chee Saw is right in what he said.
You ever used water cooling before? Ever had any involvement with it? If you did then you' d know that watercooling requires a lot of maintenance. Even the newer water cooling systems have to have the distilled water replaced every year or so.
t' s all about users comfort.MS needs to learn that.
Would it be a smart thing for Microsoft to require everyone to send their X360' s to a service center every year to replace the distilled water? No. Would it be comfortable for consumers? No.
Water cooling is not very portable. You' re supposed to be able to carry around consoles to friends places so they' re subject to " wear and tear" . It wouldn' t be very cool if you accidentally knock your console and have it leak water all over the CPU.
The PowerMac G5 is not the best thing to compare a console to. They' re a full tower sized case so they have room to put tunnelling systems and silent heat dissipation technologies. The X360 is much smaller than a G5 and therefore cannot have these systems in place (unless you want a massive console).
I' ve read up on what the X360 uses to cool itself and I think Microsoft pretty much used everything that they were possibly able to. Technically the X360 uses Watercooling but it' s actually closer to a heatpipe. Yes, a heatpipe does have liquid in it and some H2O as well, but is usually primarily ammonia. In a heatpipe, the liquid at the “hot†end vaporizes, and is moved to the “cold†end of the heatpipe by a pressure differential and convection. Once the heat is transferred to the fins in the cold end, the substance condenses and the process repeats.
You' ve got to realize that Microsoft, Sony, Nintendo, etc are offering us insane levels of technology for only a couple of hundred dollars. Do you want another couple of hundred dollars added on to satisfy your silent needs? Technology is advancing faster than cooling methods can cope so don' t expect your PS3 to be any better than the X360. Expect it to be worse.
