Liquid cooling may hold large market share in 5-10 years

In idle, my CPU cranks out 60C. My GPU sits at 58C while running Vista. This is the temperature of my computer without account of hard drives, sound card, RAM, and motherboard. In reality, I am not even running on high end hardware (Pentium D 3.0, GeForce 7600 GT). Today computers accumulate very large amounts of power; 400-1000 watts compared to 100-120 (About the amount of a light bulb) 10 years ago. Today there are graphics cards able to accumulate 500 watts alone. The more powerful computers get, the more power they require, and in turn get much hotter. With growing temperatures, air cooling may not be able to handle so much heat. Manfucaturers are already looking for other ways of cooling, including liquid cooling. Liquid cooling is probably one of the most perspective technologies.

Up until the late 90's, liquid cooling was only available to mainframes/servers. Enthusiasts would put together their own liquid cooling from scrap materials, which would leak and were generally very unreliable. After the 90's, companies began offering liquid cooling mods for normal desktop computer users. These mods are more compact and have better results than home made versions. A few years back,, liquid cooling began to appear in higher end, premade computers such as the Alienware Area-51 ALX.

Liquids have a higher heat conductance than air, which is why they are so efficient. Liquid cooling can also heat more than one component from a single cooling set. The setup of such units is very much like in a car; water is circulated though the hot spots and then cooled with a radiator.

With temperatures rising higher and higher air cooling is struggling to keep computers at the right temperature. Over the last few years, manufacturers have found ways around this by applying larger heatsinks. However, the average temperature of new computers is still on the rise. Some computer manufacturers have also added larger and more powerful fans to computer cases. This creates lots of noise, and is not preferred by most users.

Manufacturers are struggling to keep temperatures lower because heat increases the chance of system failure. An overheat can render the hardware unusable, which would mean that the manufacturer has to replace/repair the product by warranty. This problem was commonly seen with the first revisions of the Xbox 360. High temperatures also cause computer hardware to ware faster. Very commonly, memory errors begin to occur in just a few years.

Laptop's also suffer very greatly from heat problems. The compact area causes minimal ventilation, if any. Some laptops heat up to the point where people can no longer with with them on their lap. There was also the battery problem that spurred during mid 2006, when batteries had to be replaced because they would explode. The reason behind the battery problem was because of very high temperatures that triggered a reaction. Just because they where "Fixed" doesn't mean the problem can't rise again.
The only problem putting any other cooling in a laptop is because of its compactness. Liquid cooling requires more room than is available, even though liquid cooling is getting more compact. Laptops are made to be durable, non stationary, which means that liquid cooling is too fragile.

However, liquid cooling may very well appear in mid class computers in the next few years. As hardware that is expensive and that heats up today gets cheaper, it will soon be available to average users. Not only this, but expensive computers will get hotter. This may mean that manufacturers will begin to increase the amount of models with stock liquid cooling. In about 10 years, if no other way will be found to cool computers, liquid cooling will hold a very large share in the market.
