Hi. I built an extreme cooling system for the Raspberry Pi. It is composed of a short length of copper pipe with a cap on one end, attached to the CPU with thermal compound in between. It is filled with Liquid Difluoroethane (or LN2, if I can get some). It is possible to overclock the Raspberry Pi to a speed of 2.4 Ghz with this device.

Wait, WHAT?

You are dumping LN2 on a Pi

That is a 1.7GHz increase!!!! Please fo further and get a 2GHz increase on that, I will happily add you to my club if you can post any proof of it!

Wonder what a CubieBoard can do, it has a 1GHz stock clock, so is obviously binned much higher, maybe 3GHz???

2.999 Ghz with Liquid Difluoroethane for cooling for 30 seconds before it crashed!

Sorry about the bad picture quality. I can't find my camera, so I had to take it with a phone. The 11 is the voltage multiplier, so it's not actually 11 volts.

I don't know how to upload the images. Flash wasn't on when I took the pictures. That was just the shinyness of the TV. Sorry, but those are the best pictures I can currently take. STUPID PHONE CAMERA!!!

I don't know what the actual voltage is. I kind of just randomly set it. 24/7 I run it at 1 Ghz with no sub-zero cooling.

Still can't figure out how to make the pictures visible.

Figured out how to post pictures so that they are visible without DLing them.

This is how you fill it with Difluoroethane:

I think 2.999 Ghz is the ABSOLUTE LIMIT for processor clock frequency.
I tried 3.1, but it immediately crashed.
