I buy antminer u1 for fun and to see what can be done with it.First of all I made some monitor hardware to see what is happening on u1 and if temp is too high to automatically stop u1 and result is not so bad
overclock antminer u1 to 3 ghz
in txt file you can see monitoring 2 times in second
first is temp
second is current voltage
third i minimum voltage
and if some of values are off chart hardware is sending Q to antminer
Now is 3.9k resistor on antminer and oversized cooling from old cpu with fan and temp sensor in cooler

These dissipate heat from both the front and back. Zip-tying a small aluminum heatsink (chipset sinks anyone?) to the back with some thermal grease, or skipping the zip ties and using a thermal pad would probably allow you to hit 3-3.4GHs with a fan pointed at it. Thing is, you have a limit of 2.2GHs without replacing those resistors, which, if you need more information to figure it out than what the user guide supplies, you really shouldn't be trying to mod them, as you WILL break it if you try.
I've only been able to get 2GH/s without replacing resistors
I have two Artic Breeze USB Fans on my 10 Antminer cluster (4 in your D-Link USB hub) with no heating problems. I took a infrared temperature gun to them and never got over 100F. Also if you plan on overclocking past 2GB you will have to do some hardware modifications

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

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.

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
If so, what metal would i use.

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

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.
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.
Well you can try it, the stuff isn't cheap. Good Luck.
And once you used it up you will have to buy more.

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.
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?

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

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