Antminer S5: Is it possible to run it without a fan while downclocked?

[tessierashpool]

Actually, the link that SerialLain included isn't the correct kind - you're looking for Novec 7000 series.  The big difference is the boiling point of the liquid - the eBay one boils at 165c, so useless for cooling, the Antminer would have burned out well before encountering this.  Novec boils at 34c (93f!), which really is amazing... Of course, this means your ambient environment needs to be far less than 93f, I believe they recommend in the 70f's.  And don't forget this still requires a radiator inside of the Novec chamber typically with water moving through it, acting as a cooling mechanism to cause condensation.  If you're seriously considering something like this, they made a really good video on how to actually do it here:

It's more practical and less sales pitch than the other linked video.

Yes actually I believe the correct one is 3M Novec 649.

3M continues to amaze me with these kind of things.

Awesome, it's cool stuff

A fish tank with distilled water and a closed loop system would be a good experiment, and cheap yeah.

 A risk of electrolysis  ?   but I would love to see it.

I believe it is possible to set the operating Mhz of the chips (from what I've seen from the videos on Youtube). I wonder if there is a point where I can completely shutdown the fan or run it at an acceptable level.

This is because I want to host them in an office and only start them at night or at low speeds.

I doubt you could run it without a fan, you could run it with quieter fans than the standard noisy beast it comes with as standard though .

yeah I got it to 55db  vs 70db for about 20 bucks.

Distilled is not conductive.


Unless it becomes dirty, that's why filters exist.

Why not stick it in a fish tank filled with veg oil? Easy peasy.

Nope, bacteria will grow.

Maybe mineral oil , but is high viscosity and has slow circulation.
Also, not thermally conductive.

Dropping a half bottle of Diesel Kleen in there will solve that problem. Make sure it has a lid and you should be good to go. Wish I had a spare S3, I'd give it a trial run myself. Sounds interesting.
