ARCTIC COOLING ACCELERO S1 REV.2 INTRODUCTION



While CPU temperatures have been on the decline recently, graphics processors seem to be taking the opposite course. For the most part, the OEM coolers on these newer graphics cards are loud and their cooling performance can be described as adequate at best. Many PC enthusiasts, especially gamers, look to the aftermarket for improved VGA cooling, while the silent PC crowd is looking for, well, silence. Arctic Cooling has been a big player in VGA cooling for some time, and their Accelero series of coolers have been very popular due to great performance and affordability. The new Accelero S1 (Rev.2) brings silence to the table with its passive, four-heatpipe design. Let's try it on and see how it fits.

 

 

 

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 into 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 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.
