GIGABYTE, one of the most well-known IT brands in the industry, started as a motherboard technology research laboratory with the passion of a few young engineers two decades ago. With the vision and insights to the market, GIGABYTE has become one of the world’s largest motherboard manufacturers. On top of motherboards and graphics accelerators, GIGABYTE has further expanded its product portfolio to include notebook and desktop PCs, digital home entertainment appliances, network servers, communications, mobile and handheld devices. GIGABYTE has risen from an eight-man office to a world-class enterprise in the IT industry.
With GPU temperatures on the rise, quiet cooling solutions are in big demand these days. Unsurprisingly, many aftermarket cooling suppliers have jumped into the fray. Gigabyte, better known for their motherboard and video card offerings, has recently come up with an interesting VGA cooling solution and we’ll be taking a look at it in this review. The V-Power (model GH-UDUP21-VC) promises great cooling and low noise while being compact enough for SLI/CrossFire use.
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.
