I'm considering making a custom mining rig and would like any tips or advice on this project before I roll up my sleeves. General thoughts are to create a submersion system out of a mini deep freezer (3.5cu ft) on a temp probe IFTT or timed system.

Id like to make a quiet profitable machine that runs stable at 110v. I would like it to be enclosed in a deep freezer full of mineral oil High frequency Low power somehow??? Ideas? Insights?

Am i getting in over my head, What unit should i use? Should I use 2 units underclocked? or one seriously overclocked? Can I prevent wicking?

Some things I will be looking for cheap to execute or test this idea is:

Test Miner(s) -s3?.s7?v9  s9? older stuff
APW3++ or other PSU
Fan killswitches
Mineral oil bulk cheap
A final Miner like s9 s11 s15 e10 841 or a T1
.

The cooling will come from what? The freezers cooling loop?
If so FORGET IT! Cooling of any sort involves moving heat from point-A to point-B. To do so requires the cooling loop to be able to move more BTU's to point-B than the heat source (point-A) produces. The cooling loop in a refrigerator/freezer is not designed to move large amounts of heat - they remove relatively SMALL amounts of heat from the contents over a long time which are in a very well insulated casing. It is only because the food is not continuing to generate more heat that the temp goes down over time.

Quick test for you: put a couple hundred watt heater in your freezer and watch just how fast the temp rises...
Just search for immersion cooling to pull up the numerous existing threads on this.

How about if someone got a normal split unit a/c compressor, and instead of using the indoor unit make small condensers in front of each intake fan of an s9 for example?  I had this idea running through my head for a couple of years now.  Put a drain dish on the bottom of each condenser to collect the water.  Maybe it will inject too much humidity in the hash boards?  Any ideas?

I contacted a few companies about installing an immersion cooling system.  The quotes I received were in the six figure range.
