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 is really simple.
1.) With a tube containing a compressed fluid/gas, the fluid comes in contact with the heat source (the cpu core, in this case) which heats up the volatile fluid and turns 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 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 it dribbles back down the inside of the lid back into the pot.
It's basic, but it gets the point across.
PRODUCT SPECIFICATIONS AND FEATURES
With a relatively compact profile and light weight, the 5X should fit into all but the most compact cases without putting undue stress on the motherboard. PWM fan control should keep noise to a minimum, but at 2,800 RPM I can't imagine that the fan will be quiet. We'll see.
You'll notice that compatibility is relatively universal, with the notable exception of Intel 1366. I would assume that this is to avoid their high (130W) TDP, but some of the Phenom and Phenom II processors approach this value. It looks like the Zalman 5X may like TDP values up to around 95W. We'll try it out a bit later on the Q6600 with a TDP of around 105W and then see what happens when we up the voltage.
