i hear a lot of the mach ii, but where can i buy one?

btw ep-uk i loved the overclocking section in CPC issue 51
 
wow, talk about speedy reply.

how do they compare to a vapochill?

noise?

temperature?

etc... im a noob to phase, although i love my water!!
 
From a post of mine elsewhere:

Phase Modding overview:

by Gray Mole

I tend to get a LOT of questions about phase, mods, and what can be done. It's very hard to put to words every mod or every variation available but I thought I'd put together a list of tested setups and what they've done before and after so people who think about having a mod done have a little knowledge behind then when they DO look.

Mach1/2 mods:

Mach units are quite good, in that they have the strongest available compressor on the market, and in the Mach2, a decent contoller. What they normally lack is both Gas, and evaporator strength.

What I'll list is the no load, and 150w load testing that I've done (comparable to an average high end single core CPU at very high clocks/load) Also, measured with a Fluke 51 on the evap close to the surface of the evap as possible)

Premod results:

Mach1 (134a gas) - -10 to -15c load, -30 to -35c no load

Mach2 (134a gas) - Same as above

Mach2GT (404a gas) - -20 to -25 load, -40 to -45 no load

VapoLS (507 gas) - -20 to -25 load, -45 to -50 no load

Post mod results:

Mach1/2 stock head with 402a regass and coilmod - -30 to -35 load, -50 to -55 no load

Mach1/2 with chilly or other evap upgrade and regass with coilmod - -40 to -45 load, -60 to -65 no load

VapoLS with new compressor (NL11F, same as Mach stock compressor) and stock head with same regass and coilmod - -35 to -40 load, -55 to -60 no load

VapoLS, same mod with evap upgrade only makes for about -40 to -45 load, -60 to -65c no load, so really for the cost, it's better for it to just have the compressor unless you're trying to squeeze evey bit of heat out of your cpu.

Mach1/2 have the nice compressor, and the new head and regass give excellent results. A regass only with these isn't too bad, but going from GT to 402a only give 10c colder on average which may or may not be what a person is looking for.

Keep in mind though, the Mach1's control system can be funny after a mod, as the reported temp at idle can reach -50 and beyond. There is an alarm and a shutdown when the temp reached and passes this, so additional mods to the electrics, or replacing the temp probe with one of a different value, needs to be done if the control system is still needed to be used.

Old VapoPE/SE/XE regassing/modding can be a little more difficult to get into simply because of the compressor itself. For that specific advice per system is really the best way.

The only drawback to the 402a, or 507 regassing for that matter, is the level of noise increase from the fans. New condensors can be fitting to the existing systems but the cost makes it something that is only of value if you're keeping the system, and you require extreme cold along with extreme quiet.

The vapoLS can still be quiet, but while the compressor is relatively small, it's designed with higher pressure and heat and that's why 507 is ok to use with relatively low fan speeds.

The use of 404a, or blended 402a setups can be quite good for those who want colder, but still the ability to use them in quieter systems. You sacrifice some of the temps, but gain the ability to use quieter fans which is nice.

I hope that gives people an idea of what to look for and what to expect from a system before and after mods. I don't list display temps much but they can be both inaccurate, and inconsistent so even the same units modded the same way can have 10c or more difference in what the display will show.

so what are you trying to say?

i dont want too much hassle. ive got £300 or so to spend on cpu cooling, and i was looking at water, but i saw a mach II and though ooh.

So if i can get one on ebay, will it be a good buddy to my G0 q6600?

Thanks
 
are you thinking 24/7 use ??? And you should be able to pick up a custom one (maybe second hand) for £300 ish
 
nah, id much rather pre-build, i just dont want hassle if it goes wrong etc.

How much maintenance is involved with phase? or is it just plug and go?

nope, probs around 4hrs a day?
 
No maintenance, just proper inslation around the socket or be at risk of frying your CPU/Motherboard.

If you get one built by a certain UK builder you will get a 1 year warranty. It will cost much the same as a pre-built unit but perform better. A stock Mach2 will struggle with a quad when you really push it. Some VapoLS units have even less capacity (between 170 and 200w).
 
hm, I'm after trouble free running. I love my pc, but the worry of condensation etc for a few extra mhz will do my nut after a while. I think a good water setup will be good for me, esp after seeing a penryn core reach 4.5ghz on water!

If you're after 100% trouble free running then get a high-end water-cooling setup imo

Amen. Going subzero has it's inherent problems that can not always be avoided.

Also, you have to have a LOT of willpower to keep from pushing your hardware to the absolute limits of what your phase unit will handle. I had no such willpower and went through 3 motherboards and 2 processors in a week after I picked up my first phase unit. It was fun, but expensive. If you do decide to phase, and you do want trouble free running, be moderate with your voltages.
 
lol, that would be me, so i think water it is. Im gonna get saving for 3 loops, gfx cards (quad rad) cpu (quad rad) and mobo n ram (triple rad).

Should keep temps down!!
 
yea just a bit lol

no point in water cooling your pwms or ram, just grab some sinks and an XTC cooler.

then maybe a tripple for CPU and NB and a tripple for SLI'd cards.
 
The swiftec/thermalright sinks + a large direct fan would be more than enough imo.

You build phase units weescott?
