Best mix of silence and performance?

Hey. When/if I get some money together I`m hoping to get my Mach modded for better temps, better temp swing and hopefully less noise.

Whats the "best" mix of everything for low noise? I think having my fans on turbo all the time under R507 would do my head in. I`ve asked Stocky about fans that can shift the same air as the mach fans but with less noise- what are my options overall?

Random ideas- would a DSH coil help with R507 heat dispersion so a lesser fan speed can be used at the front?

Could 2 quiet/slower fans be used at the back- one on each side?

Would a waterblock shaped like a cap be a possibility for the top of the compressor to help keep it cool?

Cheers!

Yeah desuper heat coil is a good idea you can run the fans at around 1900 but if you are doing serious benching then turbo all the way tbh my gcard fans are the noisiest item in my case they are far noisier than my mach :)
 
The mach fans are easily the loudest part of my rig, so controlling them would be great. My GPU stock fans are pretty quiet, and when I got to water on the GPU, that`ll be even quiter (he said...hopefully)

Guess finding replacement fans would be an important part of the mods. :)
 
Bear in mind that a lower noise fan is likely to have a lower pressure which = less cooling. I think if you want more quietness you may have to sacrifice a touch of your temps (noise vrs temps always ends up being the trade off)

A watercap wouldnt be possible IMO.

Watercooling the compressor itself isn't necessary and it's really all that much good either. The cooling it gets, at least in our systems, is enough from the returning refrigerant and a little bit of fan power.

Best way to get quiet is to get the biggest condensor you can, in as free an airflow design as you can get. The one I'm using on Boardy's big mod is a good example of it. It's about the largest one that will easily fit into a mach chassis, and the fins are a little more open.

We're using it for maximum performance, but it would just as easily work to be able to get reasonable cooling with slower fans.

I suppose it's all in what you want from your unit. Really if you were to install a chilly head, and put it back to 404a gas (GT stock) you'd still have a heavy boost in cooling and be able to run virtually silent.

Adding a DSH coil will help too, but not nearly as much as a larger condensor though.

Ah well, just depends on how much you want to spend I guess. Cold isn't too bad, and neither is quiet. It's very cold and very quiet that ends up costing ;)

Large fins or heatsinks attached to the compressor could be cool! :B

In the next month and onward I hope to be adding many fans to the testing including coupled with a PA rad - so the resource should become much more useful :)

@Gray - when the unit arrives do you think you could do a thread on it with pics?
 
iv seen em b4 :) iv got a cool idea, water chilled condensor on one unit lol, the run the chiller back into the condensor of the chiller, be fairly quiet. Would that work? chiller - hx of big unit -chiller condensor-chiller
 
Non of these are bad ideas - call me old fashioned though, wouldn't a bigger compressor, mounted in a bigger box (height not width) using a big condensor with 12v fans in push/pull configuration be just as good?

Would not not have to run as fast to provide same cooling, slower compressor = less noise, big coolers = less fan speed required for good temps?

Then use an expansion valve to control the temps you need.

IF compressor temps are an issue place some fans on the left and right panel (staggered preferably) to provide air flow across the compressor? Or just make some fancy vents with mesh on them to allow more warm air to escape.

Simple, but effective and reassuringly expensive no doubt :)
 
The water cooling on the condensor has been done before and can work really well. Especially if you already have a basic w/c kit. Doesn't take much to adapt it. It's only the room really.

Mav's idea is about right for both the 'cross venting' and the larger condensor, BUT when it comes to compressors the larger the louder unfortunately.

Funny with the compressors, but there's a few that for some reason are just quieter than others. The mach2 Danfoss is among the best, but a slight boost can be had from the Electrolux MP14FB which is a 404a rated 1/2HP compressor that's really no louder. It's not easy to find 'quiet' compressors really.

Size is normally the toughest issue. Making it all fit into the case you want it to.

Using an expansion valve is great in theory, as it does the work for you and makes it adaptable, but thermal valves are more about capacity than coldest temps, and adjustable valves are a pain as you have to adjust them for every system, and they can take 'tweaking' on a regulor basis to get best results, and can freeze up sometimes making it a pain to adjsut and making it necessary to shut down to be able to get adjustments done.

There's always something that's not 'ideal' in every system.

But yeah, a watercooled condensor if you had no real space issues might be the best way, as you can use a 120.2 or .3 rad with nice quiet fans and get FAR better cooling of the gas than with a conventional condensor. And the construction of a heat exchanger doesn't have to be all that expensive. It's just the space really. If you wanted that to fit into a mach 2 chassis you'd be VERY lucky ;)

IT could be possible to make a modular watercooled HX add on that sits (like a sandwich) between the Mach and a Case in it's own 'little' (probs 200mm in height) box with all sorts of vents arpound it to let it 'breathe'.

But I guess if a custom case could be made twice the height of the standard mach, use high quality oil filled rubber compressor mounts and concentrat on using a 2x120mm condensor and a desuperheater coil (if you make this line with tubing that has fins on too like the 'old style' oil coolers a coil might not be needed) then I guess silence would indeed be golden?

Of course the side fan design (staggered and exhaust set higher than inlet) would be a great addition.

We could also consider externally mounting a 3x120mm condensor on the outside of the box? Or adapt an external solution like the EXOS2 to act as a condensor? The condensor (PA120.3 style) could even be mounted underneath the chassis (using legs to lift the mach body high enough) which would also provide air flow into the chassis to cool the other components?

Mav

PS: The ultimate would be a mount a mach in a Mountain mods style (as in external dimensions the same as a MM case, fabricated to keep cost down) using a 3x120mm HX and a 1x120mm HX, with finned tubing and desuperheatercoil, superior anti vibration compressor mounts and use a 'proper' mountain mods case to fix ur system to it............. submit your quotes to me now :)
 
lmao

yup, the MM custom would be ideal really.

I've got someone now who can make that or any other custom case really, just waiting to find out pricing on that MM kind of case.

But it would work VERY well, as the watercooling system and the phase system would very easily fit.

Lol but yeah, all it takes it money I suppose.

And here's me thinking bog standard basic just using a simple 120.1 rad to cool the h/x mount the rad in the front where the condenser would sit use 2 x 120mm fans push pull run the water pipe out the same hole as the evap tube to a pump
 
lol well the last thing you want is to keep it simple Fats ;)

Not sure if the 120.1 would have the power to keep things cool without resorting to louder fan power or not.

And the HX might have to be large enough that it might not fit nice. I suppose the coil in tube like you used on your chiller would work quite well and should be compact enough to fit as well...

Mmm not a bad idea, just a matter of testing to see if the rad would have much more cooling power than the condensor would anyways.

Only thing I'm not so sure of on that is the configuration of the HX if it was like the sideways mount coil in tube, as it's not the ideal way to set up the condensor really. If it was a downward spiral it'd be perfect but might not quite fit the setup for stock mach2 chassis that way.

OR perhaps using a finned piece of tubing (like an oil cooler pipe) dipped into a water tank (which is part of a watercooling loop) insted of the desuper coil would work really well?
 
That might be awkward to make? The coils would have to be more widely spaced, so less coils would fit in a mach case... then again, if the heat dispersion is better....would the fewer coils matter? OR (LOL) would the 2 be about the same?

If the coil was shaped, then appropriate disks were welded/brazed etc along the legth of the coil? Would look a bit like a spine?

I`m loving the ideas coming out here :)
 
A single loop hx coil pipe in pipe in the inside of the mach a 120.1 I think would be sufficiant as all you want is a 5 degree variation there about maybe have a small coil leaving the hx as a liquid acumulator

Click to expand...

Or hows about a chiller to chill the pipe :O

:whistle:
