Phase cooling?

Along time ago, approx 3 BK (Before Kids!) so about 2004ish I ran a vapo LS system on an A64 rig. Achieved some nice clocks, had the LS unit modded and had a frostie board and a chilly1 head fitted. Now it's not been fired up in years, so most likely need the gas recharged, what I was wondering is with the voltages lower, and die size less, has the heat produced from a processor decreased, or increased? Does anyone still phase at all? And if not, why don't they?

There was a few people on here who had phase, I think one was simon maltby? name seems to ring a bell.

Anyways any input would be appreciated.
 
I was just wondering the other day what happened to phase cooling. I was considering the Mach GT at the time but you don't hear anything about it nowadays. I wonder why not, what was the reason for it's demise? It's just custom water or LN2.

I think most phase boxes struggle with the 300w or so modern cpu's kick out and finding a high spec one is hard. They're also noisy and expensive. No technical reason why phase change or thermoelectric wouldn't work on modern kit.
 
The name was simon maltby, and I see he is still lurking on these boards, although from checking his posts, looks like he's gone high-end water. I'm hoping he might drop by and share his thinking. From the little digging on the net I have done myself, it seems quad cores in particular throw off such heat that the vapo struggles to hold the negative temps once you start juicing the chip. Seems a few still vapo in Holland and central europe. There's a few youtubes about with people with i7's etc.

Most likely, it's simply not worth the effort of insulating the board, dealing with a noisy compressor for maybe a modest 400-500 mhz over a decent watercooling rig that is near silent. On the A64 you could squeeze out near a gig of overclock with a good board and decent ram. That equated to near a 50% overclock, if you consider you may get an i7 to maybe 4.9-5gig, you looking at more like a 25% overclock, and water can prob get you 15%. This I would think is why nobody bothers with phase these days.

22nm uses less power than ever. :confused:
It was only the Q6600 that caused heat problems with the Vapochill LS. Haswell and Ivybridge produce very little heat.

I read phase has died out because since around Nehalem? the addition of various components around the CPU socket area has made guarding against moisture a lot more difficult. That was a long time ago.
 
The temperatures you see at load aren't an indication of how much heat the chip kicks out though, it's heat load in terms of watts that you need to consider.

I run 24/7 so I could pretty much answer any questions you have

excellent, what are you running currently? Have you a modded machine? ie regas or head mod? Your sig shows amd chips, have you tried intel? where did you get the machine from? Do you belong to a phase group here in the uk?

Ok Ok, it's like the damn Spanish inquisition here.. but if you could be kind enough to answer, I'd be most appreciative.

I'm running this...

Bought it off eBay, it's a Mach 2 GT that has had a de-super heater coil and a Chilly 1 evap added and then re-gassed to r404.

It's tuned for around ~220-230w of heat load.

I run this overclock 24/7

Ignore the none validation, had bad RAM at the time.

A video I made during the overclocking phase... Ignore the black country accent :p

And there isn't a UK Phase group to be honest.... You have the Benchtec forums but they're dead...
 
LD makes nice units but they're way over priced.... I've owned 2 of his cases with built in phase change...

Phase is awesome as with the right chip you can run over locks you just can't run on water...

My 2500k is run daily at 5.5Ghz and my 2600k goes even higher.

They cost as much as people think to run either...

Noise isn't that bad and if you game on head phones you can't hear them.... I've heard water loops that are louder then my phase unit.
