Scratch Build – In Progress Phase Changer RIG.

So Here I am with first Test run of my Phase Changer unit.

Yesterday evening I have started working on the Phase changer.. till 9 PM I am finished all fitting and ready to fill gas a test run..

Since this is initial testing so I have not vacuumed the unit.. instead I have just flushed some gas through first and then just filled the R404a gas.. and started the unit.

Initial temp was good but fine tuning the capillary placement in the evaporator.. I was able to reach
-36C.. YES…COOL

Turned off the unit let it heat up to the ambient temperature.. Now again started the unit to check time used to reach a temperature .. for ambient to -36c in just 3 minutes.. and power consumption is just 0.4 amp …
(All analog and digital thermometer are calibrated in a Laboratory.)






























Not tested with 200W- 220v AC of thermal resistance .. At full load for more than ten minutes temperature remains to -32C.. …
Mind I have not vacuumed the unit (It takes about 2 + hours).. after that I hope to reach -40C.. will do vacuum afterwards.


Now assembling the PC together and insulating the evaporator.. it’s 1am so should have a sleep now..











Will update more soon..

Very nice build! Not many phase change mods in here!

But are you sure the acrylic piece will hold up to the temperature changes in the evaporator? Just wondering, I don't want to see it shatter in there.

 

Thanks Sir,

I have tested the Acrylic piece under -20c inside a chiller unit for two or more hours.. and nothing happened...

Anyway if any thing happens .. i will try some thing else then... meanwhile want to proceed with this .

 

That sounds promising!

I've never used acrylic under those temperatures, so I was just a bit worried!

 

Some More update...

Insulated the mobo...(Still waiting for i7-2600K from RMA)..



















Have to purchase a GFX.. and a good one...

Hope all are enjoying the build same as me.

why does building one of these from scratch just not seem safe to me?

 

Driving a Car is also not safe.. even walking on a road is also not safe... but we all do it...
So.. just enjoy the life man...
I enjoy modding..

 

no less safe than running the same hardware on a test bench but

 

I've always been tempted to have a go at phase change but i've always been a bit scared!

This mod doesnt make me feel any more confident!

Great work, really impressed.

 

Sorry to de-rail the thread a bit, but the surface area of the CPU block is larger than the CPU, what happens between the block and where it overlaps? Do you put something there to stop the cold getting to the motherboard or just leave it?

Thanks

 

Thermal Insulation sheet on back of Mobo and mobo Tray...
Insultion clay filled around the cpu socket then a insulation steet layer above..

 

Nice job so far man, is really coming along. Always have loved the phase cooled pc's. Just found one for sale on ebay... so tempting

Got New GFX and i7-2600k ...

 

Your build is truly inspiring. Mod on!

 

More Updates
RAM Cooler

















Adding Handles







Some Cable Managament..






Some OC..




Evaporator at -36c, CPU socket backside at -23c..




5.2Ghz. it was easy..

Now have to refill the Phase changer for better temp..

Will do more OC till Sunday..

Great mod cant wait to see how far you can overclock it! Keep it up
