SERIOUS cooling for Antminer U1

[U1TRA_L0RD]

Why would someone emerge it into oil, Why not use antifreeze?

Antifreeze is mostly water, so is electrically conductive.  Oil is not electrically conductive.

DERP.

I've also heard of liquid nitrogen cooling.

So could i have my USB HuB turned upside down over a tub of cooking oil, and have say, half the miner submerged, it would work as a cooler

Also, on the OC guide on the PDF Guide says the frequency hex is 5381, does that mean it would go to 4ghs, or is there soldering involved to get that done?

You can get one of these for like $10 shipped.  Friggin powerful fan.

I'd recommend adding a heat sink, although it is a bit of a fuss it probably works best.

 DO NOT USE COOKING OIL!  Some vegetable based oils have contaminants and acids that can harm your circuit boards. Not to mention that vegetable oil polymerizes when in contact with oxygen and heat causing a helluva mess.   Oil cooling is inefficient but if you must, obtain the purest Mineral oil you can or oil that is designed for electrical cooling

Immersion cooling is an interesting option, but doing it right is a tad pricy.  Novec 7000 is about $300 a gallon.  Mineral Oil is much more affordable, but is pretty messy.  You might be better off attaching a larger heatsink to the devices, or maybe a very large heatsink to all devices at once.

Immersion cooling is expensive and messy. Just install a heatsink!

Im going to buy liquid nitrogen. Its colder, and when my GPU or CPU heats up, I'll just pour in some more.

That stuff is expensive and dangerous. You can easily freeze you hand, and if not, break your rig.

Some guy demonstrated it on youtube. Its easy.

I never said it was difficult. If you leave your hand in the stuff for more than 3 seconds, you're a goner. And it could potentially freeze your rig and render it unusuable, unless you have a safe system of pouring the stuff in.

Im pretty sure its safe I am looking for the video right now.

Well you can try it, the stuff isn't cheap. Good Luck.

And once you used it up you will have to buy more.

Could I just use thermal paste and attach another heat-sink directly to the back of the current metal heat-sink directly. Could I in essence attach a long ie 15cm piece of metal to increase the surface area to cool down and still use a fan.

If so, what metal would i use.

I currently use a Ghetto Wind Tunnel made with a USB Desk fan and a Coke bottle with the top and bottom cut off.

Could I ramp this up and make a larger wind tunnel with 30x30cm bits of metal attached to the back of the miner

I think it's okay to do so, i don't see any problem with that.

[acheekymonkeyuk]

What metal would be best to attach directly to the current heatsink in 20x20cm form and would help dissipate thebest

If you are willing to spend a lot of money, then attack a strip of silver or gold, they actually conduct heat the best.
If not, use a piece of copper or aluminium. Be careful though, silver and gold are also very electrically conductive.

[phoenixrising]

What that guy was saying about attaching metal to the current heatsink,

would it just be a case of getting a 10x10cm piece of aluminum and thermal paste it directly to the current heatsink increasing the surface area for a fan to cool
