Phase Change Cooling

[djrinsa]

Got a Quad Core on order with Aria, and im interested to get the best out of it using Vapour Phase-Change cooling.

Anyone know much about it? I have read up a lot on it but the only thing I am having difficulty with is finding places to buy the units in the uk! I know you cant link to competitors sites, but if anyone knows then drop me a PM :)

I spose I could always try and build my own :D Quad 4Ghz Cores sounds like it could be pretty fun :D

Wouldn't water cooling be easier, and possibly as good?

[Aaron]

Phase change will get far lower temps when done properly. Remember, water can only really cool to the ambient temperature of the room it is in. Phase change will get below 0/c. If you get one of the vapochill units, its fairly easy once its all plumbed in. Just need to watch out for the condensation! Here's a good review, Peter. Keeps a P4EE clocked at 4ghz at a temp of -33/c at full load :D I dont think water could get close to being that cold! ;)

There are a few places that sell the Vapochill stuff over here, which is the one I would go for, but you are probably talking in the £400-£500 range. Am I right in thinking the Prometia range stopped being sold in the UK a few months ago?

-33 :O

[tystar]

thats just ridiculas, why would you wanna spend £500+ on a case?

[Aaron]

Its the cooling system in the case that you are spending the money on, not the case itself..

[tystar]

it's still a case.

[coiler]

if I had the cash I would prob pay £500 for -33 :O

And upgrade your Athlon XP 1700, 512mb ram & fx5200 graphics card at the same time ;)

Or are you planning on trying to clock ur cpu to the speed of a x2 6000 ;)

[coiler]

4200 x2, 2gb ram, 15gb raptor, 1gb 7950gx2 and still not found a game which even falls sub 30 fps ;) ;) ;)

(don't mention crysis as we all know its pants)

[Aaron]

Yeah i guess you could look at it like that, in which case you're right - £500 is way over the top and all the cooling stuff inside wouldnt be used, and if you just wanted a case only, you wouldnt be looking at VapoChill units anyway.

But on the other hand, if you did buy a case for £40 or however much, and then bought all the phase change stuff on top of that, you could very well be looking at a similar bill.

People dont buy these things for the look of the case it comes in. They buy them for the cooling equipment that comes as a package...

[Aaron]

And I just re-read that and realised it could have sounded very stand off-ish.. its not meant like that.. :lol:

Nah dont worry about it.

I just dont see the need in all that cooling. would you really see the difference whilst playing cysis, ut3 or something similiar with ur system running at -33.

if i spent that kind of cash of cooling my system i'd be to scared of tunring it on incase something blew. :lol::lol::lol::lol:

[Aaron]

I dont think its made for the general every day user tho - you probably would notice a difference if you managed to overclock your 2ghz cpu to 4-5Ghz! :D

But yeah, I agree.. It is a HUGE wad of cash to spend on a bit (although a VERY good bit) of cooling!

[coiler]

Are there any reviews of the max OC people have got on this case?

[PeterStoba]

£500 for -33? surely i could get my Q6600 to around 4GHz? I may look into this, but before that i need to get a better motherboard and more ram.

Is watercooling cheaper does anyone know? and can i get similiar temps?

[Aaron]

Yes, watercooling is generally cheaper. And if you tried to get -33/c with a watercooled setup, you would end up with tubes of ice!


Watercooling uses a radiator to exchange the heat from the water with the air around the radiator, and so cannot reduce the temperature to lower than the ambient temperature of the room that the radiator is in. At the end of the day, it still uses air cooling as the main heat exchange process! Its just a more efficient method, and it can do it outside the case where the air isnt being heated up by other components!

Just get one of these and save yourself 5 ton

:lol: :lol:

[alexnifty]

Its really for someone who already has the best of everything. Personally I would spend £500 on a new graphics card and processor!

But if you already had the best available of everything then you are a loon who can easily see the logic in buying yet more stuff!

[Aaron]

Yeah, I agree..! Couldnt have put it better myself..

You can pick up a second hand unit for around £250 - They would have been custom made for about a 200w load at about -40ish, so even if you push a Q6600 to 4Ghz per core, it would be producing 300w of heat, which would still be at sub zero temps :) Might even be able to push it to 4.2Ghz at a guess? Will get back to you when I do eventually get my hands on one of these babies!

Of course, you could always go down the dual-cascade phase change route, and get to temps of about -100c - would allow you to easily achieve 5Ghz on a quad core... Although, unless you wanna build it yourself, its unlikely you will manage to get one!

I dont think £250 is a lot for the amount of performance increase it gives you - And lets not forget the quad core 45nm Yorkies arnt far away, and they can be overclocked to 4Ghz+ ON AIR!!! Imagine that with a decent Watercooling or Phase change rig :D

As you can see - I did a lil research after my first post ;)

They are noisy lil buggers though, apparently.
