Condensation - Sub-zero Water Chiller

INSULATION AGAINST CONDENSATION!

Hi guys,

  • I finished modifying my Water Chiller's electrics to bypass the Thermostat last night.

  • That means she's almost sub-zero ready. I've also finished researching a compatible sub-zero coolant.

  • Last Step Been researching some insulation methods and there are literally so many ideas.
CPU + Full Cover GPU block (EVGA 1080 Classified)

I'm looking for something that will be easy to remove.

Ease of removal is my no.1 priority. Most material I've found doesn't talk about removal!

Wondering if anyone with more experience than me (whose maybe tried a few different techniques) could advice on this?

A million thanks :)

If anyone is interested in my project give me a PM or even reply here and I'm happy to provide details or any assistance :)

I quite enjoy discussing the topic too and discussing overclocking :) I have a lot to offer with my knowledge around Pascal overclocking :)

Best regards,

Nick Peyton

yeah, it's not that simple. I run a couple of chillers (Koolance EXC-800 and an AquaEuro 1/5 hp aquarium chiller like you have in the pic) on separate rigs. Dew point is critical as is your geo loaction regarding humidity levels. The only way to condensation proof the rig is to stop/block ALL air flow into the box, flush the box with dry air, Nitrogen or any dry air source. Compressor air is fine - all the moisture has been removed during compression - and then bring the temp down. Absent a sealed box, you wil always get condensation as soon as the cooled surfaces drop below the dew point temperature.

Hailea HC-500a (aka Ultra Titan 1500)
-790w cooling capacity

-lower (sub-zero) temps with a very easy-to-do mod

I paid: £200 (about 245$ U.S dollars) <---- 'used' from Ebay

Not that loud; if you had headphones on you wouldn't hear anything.

Without headphones in its acceptable if you're sitting right beside it... at the opposite side of the room it probably wouldn't bother you at all.

I can go down to about 5c water temp before condensation starts to form (on a good day).. on a bad day maybe about 9c.

I use a dew point & relative humidity meter ($20).



Can I just wrap the GPU & block in air proof bag, try and get as much air out as possible then seal it with duct tape? Would that help at all? I really want to go lower. The chiller is capable of it.

You can bag the blocks, but that's unnecessary if you can make the case as air tight as possible.

Hmm I never thought about making the actual case air tight.

I have a Corsair 750d airflow edition.. so the case is actually designed by Corsair to be anything but airtight...

I've heard about people using 'Liquid Electrical Tape' but I'm worried about removal. (afterwards)

coating the board and all attached cooled devices with LET or any one of the silicone "skins" (check any of the extreme cooling websites) only mitigates the condensation effect, and if you go sub-zero for long periods of time (hours), it is certainly not enough alone. Like I said, only real way to avoid condensation is to seal up the case and ideally have a slow "bleed" of a dry gas (air, N2) into the case to ensure positive pressure in the case.

There are no easy solutions then?

That sounds like a massive project. I thought after everything I've already managed, this was just the last (and cheapest) final step....

Thanks for the info, I've added to your rep.

Must admit I feel a bit deflated now though; never anticipated this being such a big step.

no reason to be deflated, just run the chiller above the dew point. they work great!`

That would defeat the whole purpose of this thread, though...

I have been working on a little project to go Subzero with it, you see.

Spent time researching a low viscosity compatible Subzero coolant.

Modifying the electrics on the chiller for Subzero and buying in arma-flex insulation for tubing and chiller tank.

I'm not expecting this to be a 24/7 solution.

But I would like to be able to run 60 minute sub-zero sessions. Before bringing temp back up to above the few point. Then performing a straightforward clean-up, then repeat.

95% of the time I will be above the dew point
But. I want my setup to be capable of supporting these little sessions. Now and again. :)

I've came this far. Not giving up now. :)

Don't give up nrpeyton.

I am building a rig with a chill box myself.

Okay agreed, I will begin researching into the chill box and look into this further :)

Anyone whose interested I just successfully went sub-zero; for the first time :)

toolmaker03 thank you :) Now its time to refine and perfect what I've got :)



Frost lol




Modifying water-chiller electrics to bypass thermostat for continious running = subzero ;-)


Insulating chillers tank



Insulating CPU



Finally breaking through :)

I've had a look at that website (looks amazing)

But couldn't find a "where to buy" section.

Nor was there anything useful came up on google, any idea where I could either buy this as a service or grab a bottle of this stuff?

Edit:
I've emailed Semblant; but I doubt they'll reply. They look awfully like one of those "companies" that only replies to other companies. Not individuls.

I am not recommending to use them, I am just linking them as an example.
I do not know if this will work, I linked/suggested it as a possibility that might work but, you will have to do your research before using it
