SCYTHE KATANA SCKTN-1000 INTRODUCTION
Today on the chopping block is the Scythe Katana CPU Cooler, a heat pipe based cooler for AMD and Intel alike. You can never have a cooler CPU these days, so anything that looks as big and mean as this bad boy has got to have some cooling power.
We’ll be testing the cooling on the Intel side of things in this review, and I personally have never felt a need to even replace the stock Intel cooler as it has done an amazing job thus far. I must admit the stock Intel cooler is a noisy little bastard though, so let’s see how quiet this beast is.

SMALL HEATPIPE TECHNOLOGY TUTORIAL
I am going to keep this as simple as possible to get the basic premise across to all of the Tweaknews readers. Please don't be insulted if this is too simple for your education level. I have to cater my writing to the least technical reader looking for information.
The basic idea behind heatpipe technology if really simple.
1.) With a tube containing a compressed fluid/gas, the fluid comes in contact with the heat source (aka cpu core) which heats up the volatile fluid and turn it to a gas. The energy is absorbed in the gas production process and is ready for transportation.
2.) The heated gas now travels along the inner portion of the tube where it comes to the cooling portion of the heatsink in this case example.
3.) The radiator, with or without a fan, will cool the liquid and transfer the energy (AKA heat) to the radiator to be dispersed to the surrounding air. With the heat removed, the vapor quickly condenses back to a fluid and runs along the inside surface of the pipe back down to the bottom where the process can be started all over again.
For another example, you can consider a boiling pot of water with a glass lid as a very very basic heatpipe. When the water boils, the water vapor comes in contact with the cooler glass pot lid which forces the vapor to condense back to water where is dribbles back down the inside of the lid back into the pot.
It's basic, but it gets the point across.
