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???

impressive, but I have to ask.... WHY!!!! just... WHY!?!?!?!??!

 

[PedroC1999]

For the sake of it, and for being the first

 

[neo565]

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

 

[PedroC1999]

Is that thing reading 11volts

And could you get a really clear picture, I would like to include you in my club

 

[neo565]

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.

You are my hero

+1

 

[PedroC1999]

What is actual voltage?

What do you run 24/7?

And could you rerun it with flash off xD

 

[derickwm]

Come on man... upload your images so people don't have to DL them to see.

 

[anarekist]

funny

 

[neo565]

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!!!

 

[neo565]

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.

 

[derickwm]

Click "Insert Image" instead of "Insert Attachment"

Or upload to Imgur first then copy URLs here with IMG tags.

 

[neo565]

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

 

[neo565]

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

This is how you fill it with Difluoroethane:

 

[PedroC1999]

Any more attempts? BTW, ADDD MORE VOLTAGGGEE

 

[Maximillian-E]

The rs spray is good, however a more efficient spray is:

Component cooler should get you there a lot easier.
We would store use those for experiments lol.

 

[neo565]

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