Neptune card in Novec 7100...

Coolness!  What are you using to recondense it, or is it just a test setup?  How much did you pay for the Novec, if it's not rude to ask?  

It was $350 shipped for a gallon of the Novec 7100.  I used a couple of peltier chips and some heatsinks to condense the Novec.  It worked and dripped back down while it was running.  I have a much bigger tank on the way with some large radiators installed for the final unit.

I am surprised the VRMs have so few bubbles.  I would have expected them to be much hotter.

@smracer:  That's awesome.  The peltiers are sandwiched between the heatsinks?  Can't wait for more pics Smiley

I was surprised as well.  Not many bubbles at all coming off the VRMs. 

I am uploading a video to youtube and I will link it as soon as it is done.

Neptune card in Novec 7100.  This was just a quick test.  Hopefully I will have more numbers tomorrow.



Looks pretty sweet.

Few questions about your setup:

Why is the pcb tilted instead of flat?

How are you dealing with the pressure? Any vents?

And do you think it would work without the peltier cooler assistance?

The PCB is tilted for no reason.  It just kind of sat that way due to the cables pulling on it a little.

There is space at the top for pressure to escape.

Sure it would work without the peltier chip in an open bath.  You will lose fluid over time though if you don't condense it.

I am using a much bigger box for my final unit and hopefully I can fit 20-25 Neptune cards in the box with a very large radiator.

I will add them 5 at a time until I can't dissipate the heat anymore.

The VRMs shouldn't generate that much heat tbh so when you have a efficient way of cooling them they should run quite cool, a few watts can easily create a 100C hotspot if there's no efficient way for it to dissipate.

Welcome to the club of immersionists smracer  Grin

How many amps is that TEC you are using?

How many watts do you have at the wall (or 12V) in this setup?


Here are videos of the AM BE200 and SP SP10 in case you missed it:

I will set it up again tomorrow and take temp readings.  I only had a short time today to mess with it.

From what I remember though all the dies were at 59C +/- 2

nice...also temps of vrms too on adv. page Smiley thxs

do you think temps will be higher when you have more units in there?

Hope you will add a control loop to turn off the power if the cooling loop fails or reaches some critical temperature. Imagine several thousands of dollars of fluorocarbons evaporating.  Embarrassed

No crazy would be if instead of using fans and radiators he used a heat exchanger with pipes that flowed through an arctic river in Iceland or something Tongue

But yes that is way cool.  Thumbs up for mad scientist of the week  Grin

Anyone know of any online cable management classes? Smiley

wow... how much you earn / month will all that? how much are each of those neptunes and hashing power?

edit: I googled and i think each of those neptunes is 3TH/s ?WOW

Sorry but what coins can you mine with those? I just used S1 and now i bought S3, didnt know about these neptunes but i suppose they are so expensive xD

Seriously? You mean each box is only 200 Gh/s?  Like an S1?
