mach 1 to chiller

[thesaucier]

What all besides an evap do I need to do to make a chiller out of a stock Mach1?

[n00b 0f l337]

Bigger condenser for sure, as well as a new capillary line. Basically a rebuild of the unit leaving the compressor. And if you find someone who can do it, possibly move the compressor forward or somehow work a miny resevoir with evap inside the unit.

[alexio]

A better condenser and probably compressor too. It makes sense to start from the ground up.

[n00b 0f l337]

NF9FX is definitly enough IMO Alexio.

NF9FX is definitly enough IMO Alexio.

For a Conroe or Kentsfield and powerful GPU(s) it might not. It is enough if you make a big reservoir and give it the time to cool down before heavy load.

The NF9FX in a direct die unit can hardly handle the load of an overclocked Kentsfield

[star882]

Why would you not want direct die? Having the refrigerant right next to the CPU is about as optimum as you can get.
Sell the direct die and buy a window A/C to convert. It will be cheaper and have lots more capacity.

[the_new_guy]

Loaded temps are inversely proportional to heat load.

if it can't handle 180 watts at -40˚C, with a shorter captube it will be able to handle it at -30˚C.

[n00b 0f l337]

Well yes but if your converting a Mach (generally use for a single CPU or GPU), then I hope he's not expecting to be loading up a huge water loop.

[serialk11r]

Sell it, get a 5000BTU aircon from home depot for a hundred bucks and open it up, then make a res!!! like the guy in the water cooling section did. He didn't put the thread here for some reason...

[n00b 0f l337]

Ah an AC conversion is very common, but at the same time its incredibly bulky and therefore reduces portability, increases noise level (generally), and in general isnt the nicest thing next to or near your comp.

[thesaucier]

WOW I really thought the compressor would be good enough. I thought mabye bigger and or more cap line would do the trik. Looking for cold temps with 4800+ and cool a nvidia 750. be OK to cool just under ambient temps. You know better than water alone. Hey Thanks for the responces too!

[n00b 0f l337]

Less capillary line means more load.
Plus you do need a good heat exchanger.

I was under the usumtion that the condensor was the heat exchanger.

[n00b 0f l337]

Yes for the highside, but for your resevoir, you need a heat exchanger (even if its copper tubing) to be your evaporator.
Personally in a situation like this to keep it small I'd vote for a plate hx.

[thesaucier]

So if I put on a coiled 1/4 inch 8inch long evap were the water passed and lenthend the cap tube what would I exspect to get.

[n00b 0f l337]

8 inch? Expect nothing, way to small and restrictive and youll have huge problems with liquid flooding.
Lenghtening the captube will also reduce your cooling potential but probably give better temperatures.

Coil in res systems generally want 10-20 feet of tubing.

Indeed. I personally really like the tube in tube type of heat exchanger. It's simple to make, cheap and if it offers pretty good performance. It's also a good idea to cool the water with the suction line (before it enters the heat exchanger). This involves a little extra work, but it can be worth it. Another variant is to cool the freon with the water after it has passed true the condenser. Just remember that you also add restrictions to the water loop.

*thesaucier: I really think for your application the NF9FX is plenty, if you upgrade to an Intel system and more powerful graphics card it might not though. For the sake of future proofing a more powerful compressor may be a good idea, but with your current system and temperature goals it's plenty.

[n00b 0f l337]

I'm still thinking about containing inside a mach1 case really. Plate HX in the back may prove extremely good, or a custom coil up top...

Yes I mean 8inch of coiled tubing that still seems a bit small I meant all coiled probibly 10 foot. So shorting my cap tube would be more productive?

[thesaucier]

Also what is a Plate HX?
Thanks for the help

[n00b 0f l337]

Yes you must shorten your captube if you want this system to work. Make that 8 inches 8 feet and use 3/8" and you can hope for something. A plate HX is a highly efficient stacks of plates that allows the efficient transfer of heat between two flows.

Is this used as a condensor or evap? can you show me a link?

[n00b 0f l337]

As an evap or condenser really.

[thesaucier]

Looks like a condensor to me. I thought the mach had a ok condensor.

[n00b 0f l337]

Condensers just a heat exchanger. And the Mach's isnt that great.
