Cool Off: Methods For Keeping Your Computer Cool

There's a lot of ways you can prevent your computer from going 'boom' as a result of all of

these factors.
Air Cooling

This is probably the most common, most power intensive, and-at least in my opinion- often the

least efficient method of cooling a PC. One to several fans are installed in the motherboard,

and these fans are used as a sort of 'exhaust vent' system. They move the hot air out of the

PC, and bring cooler air in.  It's not that this isn't a good means of cooling a system. I

mean, if it didn't work, it wouldn't be integrated into almost every laptop and PC on the

market, would it?

The thing is, though, is that air cooling simply isn't as effective as the other methods on

this list. Not only does it increase the power draw of the system, but there's also a certain

limit to how much it can do. After all, a fan can only move so much air, if you're

overclocking your system through the roof, the fans might not necessarily be able to keep up.

Granted, there's several different types and sizes of fans you can get- some of them are

actually quite powerful.  Plus, air cooling does help prevent dust buildup on your computer's

inner components.
Heat Sinks

Another method of cooling the computer is to use a heatsink- a piece of metal that absorbs a

lot of the heat generated by the PC. There are three different 'types' of heatsinks. Passive

heatsinks involve simply clamping the piece of metal onto the components to be cooled and

calling it a day. The problem with this one is dust buildup. Since it acts as an insulator,

the effectiveness of the cooling system is gradually reduced.

An active heatsink adds a fan to the mix, constantly blowing over the metal. This

accomplishes two things: first, it helps to prevent dust buildup on the heatsink. Second, it

reduces the overall temperature, therefore increasing the amount of heat the cooling system's

able to dissipate before reaching its limit. \

Finally, there's a nifty little innovation known as thermoelectric cooling.This involves

using the Peltier effect in a cooling system. Basically, the Peltier effect stipulates that

if there are two different metals between which heat is flowing, and the second metal has a

lower capacity for heat absorption from the first, the heat will have to dissipate before

reaching the second. Thus, the side  that absorbs the heat becomes hot, the side that

releases it becomes cold.

The lack of moving parts makes this a pretty nifty means of cooling a system, but as systems

generate more and more heat, it gets harder and harder to find a thermoelectric cooling

system that will work- or at least one that doesn't break the bank.
Liquid Cooling

We're starting to move towards the higher end stuff. Liquid Cooling involves a series of

tubes, a water pump, and a radiator. The water in these tubes absorbs heat from the computer

components, is carried to the radiator, and dissipates that heat. Rinse and repeat. It's

quiet, it's efficient, and it's probably one of the most popular cooling methods. Plus,

unlike some of the other methods, the liquid cooling pipes can run through the whole

computer, whereas with heat sinks and fans, you can usually only focus on the one or two

components that generate the most heat.

A lot of gaming PCs- I'd say the majority of them- utilize this method of cooling. It works.

Just make sure the pipes don't break.
Liquid Submersion

Now we're talking. Liquid submersion is exactly what it sounds like. Basically, you take the

computer's The Reactor X DesktopThe Reactor X Desktopmotherboard, and dunk it in a liquid

that doesn't conduct electricity, such as mineral oil. And then...well, you're pretty much

done. It keeps the computer cool, it doesn't make noise, and there's no risk of a pipe

breaking and your computer short circuiting as a result. I've a friend whose hobby is

building PCs, and he swears by this method.

Another advantage is that this one doesn't have to be cleaned very often, unlike some of the

other components. Dust buildup's an issue with a lot of desktops and cooling systems, but

liquid submersion...kinda circumvents that a bit.

You may need to insulate or otherwise shield some components of the computer, depending what

liquid you're using; and if the liquid isn't sealed in, evaporation could be a concern. Other

than that, though, this one's pretty nice.
