Yes.

Great choice! They are powerful and almost inaudible...

[LittleDevil]

Aften 2 hours on load.

Very nice result!
Is that done with a Danfoss NL11F compressor?

And is that new condensor one from LUVE?

[LittleDevil]

Yes Danfoss NL11F and old condensor. Waiting for new fans, than we will see new results.

New front design of Rotary units.

[UTerror]

I finally finished my build! (for now)

Placed a phase-change unit in a LianLi V2010B.







I've got 1 of the old type of units with the 220V fan which makes lots of noise
So I changed the fans into 2x scythe slip stream 140 mm (push/pull).
Temps are a little bit better then original fan (+-5 °c without a load).

Suction line was a bit too long, but fixed that by routing it in bottom half of the case.

Tested it this week and it's working great, but I need to order some parts like power buttons, wc block for motherboard (vreg gets too hot), cable holder's, ... I can start painting the case when that arrives. Should be fully finished in about 1 month.


Greetz,
UTerror.

[LittleDevil]

Nice rebuild! You shout show us picture of finished unit also =)

Load test.

[cdolphin]

NL11F is holding 283W at -30C? Nice work!

Also, isn't the COP for that unit like 85%? 283/354?

Rotary unit on load.

Hi LD,

Is it possible to run the compressors at a lower speed when the computer is idling to save on power?

[FinBenton]

How much for the case and cooling unit?

[LittleDevil]

Hi LD,

Is it possible to run the compressors at a lower speed when the computer is idling to save on power?

Hi. That is not possible. If your system is idle, power consuption of phase change unit is not that big than on load, but you can't run compressor at lower speed.

you can use vcc rotary compressors which are controlled by frequency.
they are often used on inverter coolers

[SAE]

But you'd need more room vertically.^^

[Jack]

And more money for the extra parts. ^^

[Patrickclouds]

you can also use full hermetic piston compressors: http://www.embraco.com/ingles/familia_vcc.htm

[SAE]

Would it be effective enough for 24/7 operation, though? Sounds nice indeed, but I wonder why noone considered that before...

[Patrickclouds]

expensive and difficult for an automatic control.

you can use a frequency inverter and select the frequency manuelly
but on singlestage it doesn´t make sense such a compressor, because you have to insulate all the parts so it doesn´t matter if you have -30°C or -45°C on idle.

You should do a quick youtube video of that case running

[LittleDevil]

@Mudgey: You got really nice answer =)

I will. What is the best software to make video smaller.
