How 'Noisy' Will The Next Gen Consoles Be?

Liquid cooling can't be cheap though?

DC had a water cooling solution of some sort. Didn't make it very expensive.

Ok, I own a DC and didn't know that hehehe. I always have the game sound on so loud when playing that I can't hear consoles anyway. :)
 
The first batch of DCs had the liquid cooling solution. Shortly after it went to HSF. DC was loud due to the GD-ROM drive. The fan was very quiet and small too.
 
Speaking of cooling.....I'm sure if vapor deposition synthetic diamond production really takes off, they'll be using that too for thermal transmission.....they already have diamond particle thermal paste. It's by far the best conductor of heat......hence its nickname "ice"....cool to the touch as it conducts heat away from your hand so quickly. We do know that in some roadmaps, the use of a diamond substrate instead of silicon is being looked at as a possibility. Apollo diamond is a pioneer in the synthetic diamond industry already selling stones that are virtually flawless and have a webpage with a lot of interesting possibilities for the electronics and industrial types.

One might be forgiven for imagining a frustrated young lover tearing his computer apart and making some high tech jewelry for his lady friend.

De Beers inside anyone?

LOL! Next next gen consoles wars over Carats, not FLOPS!

That's all fine and dandy but how do you transport the heat? In a active liquid cooling solution the liquid is pumped around. I think a liquid metal cooling solution would be a lot better than what you've proposed.
 
Yeah, i saw the gallium story on the Inquirer on that, thing is given that it only becomes liquid above 85.5F there's a tangible warmup period before the whole system can be circulated around. I'd imagine they'd have to use a prewarmer to totally liquify it before allowing full load operation. As for the diamond aspect, certainly would make a very good heat spreader I feel.

You're not seeing the big picture. Sure the noise will be coming from the fan, but if you're using a liquid cooling solution then you can use a less powerful fan since the a liquid solution is more efficient than a nonliquid solution.
That's a reasonable assumption, had the X360 been equipped with liquid cooling, which it IS NOT.

It supposedly has a heatpipe cooler according to very sketchy reports, which does not qualify as "liquid cooling", mainly because it isn't any liquid that does the cooling but rather a gas. If anything, it might qualify as a sort of phase-change cooler, but in reality it's just an improved version of a bog-standard heatsink.

Also, DC did not have liquid cooling EITHER, that was a heatpipe as well.

And a great many millions of PS2s also had heatpipe-equipped coolers, but nobody ever made any big deal out of that.

Well the DC had a heatpipe but inside the pipes and pads were a liquid. The liquid had coolant properties IIRC.
 
From the video that was the final prize in our colony (Link) I can count no less than four fans.

@ 1m33s a guy is holding up a motherboard with 2 fans over the CPU/GPU heatsink(s)
@ 2m30 another guy is saying "We have a dual exhaust fan system here, in the rear" while pointing at the rear of the console.

I know that it may not reperesent the final design but it does raise som concern about the noise level.
 
Better to have four small fans then one, as one will have to spin 4x faster to move the same amount of air.

As long as they are high quality fans it shouldn't matter.
 
Here's some info on the XBox360 cooling solution I found:
One of the surprises we found when checking the Xbox 360 innards was its cooling solution. To keep things quiet and cool, Microsoft has designed a liquid cooling system that dynamically adjusts the flow of the liquid and the speed of the fans depending on the temperature and power consumption.

This intelligent approach has allowed Microsoft to build smaller console by removing the traditional heatsinks found in most computer and replacing them with a combination of fans and liquid cooling. This combo is more efficient and keeps the processor at a lower temperature than the original Xbox, which is a remarkable achievement considering the higher clock speeds and power consumption that the new Xbox 360 hardware has in comparison with the old console.


Not satisfied with that, Microsoft has also used a high-end technique that allows the system to turn off the cores when they are not being fully utilized. So let’s say you are watching a DVD movie or just listening to music, the system will automatically turn off the two cores that are not being used for the console to consume less power during that time.

There's one more strategy I'm sure all 3 next-gen consoles are employing - external power supply(brick). Shrinks the unit, reduces heat, removes at least one fan - three birds with one stone.

Isn't the XGPU passively cooled? So the only major thing to cool is the XCPU? If they do a good job on cooling the XCPU the system should be pretty quiet.

GPU at 500MHz with 200M+ trannies passively cooled? I'd love to see how they manage that.

the entire Xbox 360 graphics subsystem is 332M trannies, across two dies, in one package, and all of it will need to be cooled ;)

[smacks forehead] ...uh, yeah, as opposed to those "other" heatpipes that don't have liquid inside. :?

For the benefit of everybody...a heatpipe is a "heat conduit" rather than a heat dissipation device. Sooner or later, you have to come to the actual heat dissipation device that moves the heat into the air. If it is a lot of heat, you're gonna need a fan. That fan will be noisy...and if you have only a confined space for the radiator (something shaped like a console, perhaps?), then you'll need a hardworking fan which is even more noisy. Therein the whole "liquid cooling automatically makes something quieter" argument falls apart. The oft used car analogy is really convenient to push a point home, but it really only succeeds in introducing even more misconception, rather than clarification. True, air-cooled engines are generally louder than liquid-cooled engines, but the end result comes from a far wider subset of factors than just if it is liquid-cooled or not.
 
Todd Homdahl of Microsoft says "This system will be quieter than Xbox 1."
Masayuki Chatani of Sony says "Since quietness is very important, our hardware team is trying to make it as quiet as possible. Though it's not compared with PS2 yet, I'd like to make it more quiet in the final product."

So in terms of noise: PS3 > PS2 > XBox 1 > XBox2.

So why have both the PS3 and X360 got kettle-lead style connectors on the back?

um yea sure


anyway having bigger fans is better than having smaller fans for system cooling .

a 120 mm fan will move the same air as a 80mm fan but at lower rpms poducing less noise

a 80mm fan will move the same air as a 60mm fan but at lower rpms


However on a heatsink things get a little wierd . a 60mm fan has a much smaller dead spot (the motor in the center of the fan ) than a 80mm and a 80mm has a smaller one than a 120 mm . How ever they will stil move the same air as the smaller fan at lower rpms . But now you have a dead zone in the middle of your heatsink .


Personaly having a two 80 mm fans in both the front and the back of the case would create the same air flow with less noise than having 4 60mm fans 2 in the back and 2 in the front .

Also as said i'm sure b oth consoles will use smart fans that will change the rpms when they are needed to be changed. I would hope that while watching a bluray movie the fan can spin much slower than when playing a game .


As for cooling well it sounds like they are using a liquid to cool a liquid metal which isn't the same as a traditional heat pipe which uses gas . The liquid will be much better at abosrbing and desipating heat than the gas version .

That is why water cooling is so popular . I was running a 120mm fan at very low rpms on a radiator and was keeping my cpu 5c above room temp . You used to be able to hear my hardrives over my watercooling system
 
I'd think there are too many variables to know at this point.

All things being equal 360 gets a +1 for water cooling. At least it SHOULD be quieter than just using more/higher velocity fans for cooling, though who knows what kind of pump its using. Actually, we don't even know if PS3 is just using fans, it might be water-cooled as well.

PS3 gets a +1 since BluRay will be spinning at a lower speed than the 360's DVD.

I am definitely aware of that. But both are still 'empty props' at the moment anyway, so still subjectable to changes. Besides if they face difficulties with cooling, I think this is a simple and effective proposal.
