How to Cool your computer down and get those nice sub-zero temperatures.
The secret to cooling your computer down is to slowly lower the temperature. Lower it too fast and you could end up with a cold-boot lock or a motherboard crash.
To help minimise the above, let us use the following steps:
- Place a small funnel into the opening of your copper pot and pour either Acetone or Isopypol alcohol into the funnel and never directly into the copper pot (safe working practices here) and fill the pot to about 1/10th of the way up (DO NOT OVERFILL THE POT) Remember to remove the funnel
Funnel to pour in the medium
- On the initial run-simply place two pellets inside the pot and let them ‘fizzle’ away. Please reffer to the guides safety instructions; that is use an old coffee or styrofoam cup in order to scoup out the dry ice pellets.

- Power on the computer and enter into the BIOS. Here select hardware monitoring (or whatever it says in your particular BIOS) and take a note of the CPU temperature.
- Slowly add more pellets to the pot but once again do not overfill, otherwise the medium will bubble over onto your precious motherboard. You should see your CPU temperatures start to drop.
 Motherboard Insulated and Powered On |
 Temperatures start at plus 40C |
 Down to 30C Idle |
 Temperaturesd Lowered to +13c |
 Temperatures Lowered to +5c |
 Minus 1c we are now starting to get into the negative temperatures |
Minus 16c Note: This motherboard sensor would not go any lower, as it was not capable of doing so.

Note it is best to use a K=probe and digital thermometer, however if this is not possible then use the Bios temperature sensor. Though this sensor is not accurate (as we all know) it should give a rough temperature guide. Once you are down to around minus 40 or below then feel free to allow your computer to boot into windows.
The following are a series of shots showing the amount of fog resulting of the dry Ice subliming in the pot.

Final Tip: As one can clearly see, motherboard sensor as not capable of going down to -79c or so that Dry Ice can obtain.
Thats it folks, happy benching
