Why Do You Need a Cooler for Your CPU?

The short answer – because your PC produces a lot of heat and you put a lot of stress on your CPU when multitasking or using demanding software on your PC.

More seasoned computer builders and tinkerers that have already installed the best SSD, RAM, CPU, etc. that money can buy will obviously be more comfortable paying for high-end coolers that will truly protect their gear.

There is a great variety of coolers so that you can find the right one to cool your system. The CPU Cooler can’t accomplish all of this cooling all by itself, however. It requires the assistance of a heatsink.

What is a Heatsink and How Does It Work?

A heatsink is a thermal conductor which is commonly used in electronics of all sorts in order to create a state of equilibrium in which the heatsink gets hotter as the processor is cooled. You need to have some sort of air or liquid to cool the heatsink, however, or the heat will simply continue to radiate back on the motherboard, CPU, and other parts.

The most effective heatsinks are comprised of copper base plates with thermal paste spread across their surface. It’s critically important that you sufficiently cover the plate with the paste. The majority of CPU coolers come with a tube of reasonable quality thermal paste, but you can shop around for something better as well.

Things to Consider When Choosing CPU Cooler

CPU Cooler Types

In short, there are 2 types of CPU coolers that are currently in use: air CPU coolers and liquid CPU coolers. There are several other technologies used for cooling but at this point, they aren’t available for the mass market.

Air CPU Coolers

Air CPU cooler is the simplest way of keeping your CPU from overheating. Decades after their invention, we’re still using them in our PCs. Why? Because they work very efficiently and require little power. Air CPU coolers work by driving cool airflow around the heatsink in order to cool it continuously as it is being heated by the CPU.

When high-quality air CPU coolers are paired with top-notch PC cases, you have yourself a highly-potent combination that will allow you to overclock in peace and quiet.

Liquid CPU Coolers

Liquid CPU coolers weren’t available to the public until the late 90’s, but innovative techies were making their own liquid cooling systems prior to that; mainly out of the aquarium and automotive parts. Fortunately for you and me, they’ve since become commercially available.

Liquid coolers are popular for a few reasons: performance, wow-factor, and noise level. As far as performance goes, it isn’t necessarily better than a good air cooling system, it’s just an alternative option.

A liquid cooling system is comprised of one or more water blocks, a radiator, a pump, and a small internal fan. The liquid is pumped from the block through the tubing, transferring heat away from the motherboard, CPU, etc. This is possible because of the high thermal capacity of the liquid used in these systems.

The details of how the liquid is forced into a turbulent flow as opposed to laminar flow to increase heat transfer are a bit tricky but interesting. If you’d like to learn more about the physics of liquid cooling, the following article “Air Cooling vs. Liquid Cooling” is a great resource.

Why Upgrade to a Post Stock CPU Cooler?

There are several reasons for switching your stock CPU cooler for a better one. Whether you’re interested in air coolers or liquid coolers, there’s a solution for practically any combination of the following:

1. Overclocking

The number one reason for switching out your PC’s CPU cooler for a more advanced model is to enable overclocking. If you’re not familiar with the term, that’s okay. That’s what we’re here for after all!

Modern processors typically run between 3-4GHz with no modification or alteration to settings. The level of GHz dictates the processing units speed.

You can alter your settings so that your CPU becomes faster, but this leads to higher volumes of heat which must be dealt with in order to prevent damage. Which is why you need an upgraded CPU cooler if you want to overclock your PC safely.

2. Excessive Noise

This is a big one for the average PC user. Lower end air CPU coolers can be quite noisy, particularly while multitasking and really putting that processor to work. Aftermarket options are more efficient, meaning they don’t have to work so hard (less strain = less noise).

Many of the aftermarket CPU coolers available also provide multiple setting options so that you can turn them down, making them even quieter.

3. System Upgrades (such as RAM, processor, video card, etc)

When you purchase a new internal PC component, it should indicate how much heat it will produce while in use so that you can analyze whether or not the CPU cooling system you’re using will be efficient, or if you need a bit more cooling power to accommodate the new gear.

4. Running Powerful Software

If you enjoy gaming on your PC or make a living as a graphics designer, you’re already well aware of the effects of running powerful software. RAM and CPU are the main components that can to increase your PCs ability to handle high software requirements. Here is when aftermarket CPU cooler can become handy.

5. Damage to System

If your PC has already suffered the consequences of inadequate system cooling, it’s definitely time to replace your CPU cooling system. Make sure that this is the first part that you take care of replacing, no matter what is damaged. That way, you’ll have your coolant system in place and ready to protect your other new parts as they’re installed.

CPU Cooler Designs

So far, we’ve covered the different types of CPU Coolers, how they work, etc. but we haven’t talked about CPU Cooler orientation within the case; which is a very important part of how they function.

Tower Style CPU Coolers

This type of a CPU cooler can be installed in two different positions, each of which provides its own set of pros and cons. The first position pulls air from the front of the case to the back and integrates a vertical heatsink. The second position pulls air from around the CPU, pushing it directly across the video card area and out through the top.

To learn more about the differences in orientation for Tower CPU Coolers, check this article.

Downdraft CPU Coolers

Downdraft CPU Coolers obviously provide a downward draft of airflow, pushing air down and allowing it to naturally rise on its own. The most common reason for PC users to prefer a downdraft model is that they are seeking a low profile CPU Cooler that will fit inside of their case easily.

How to Choose the Best CPU Cooler for Your PC

Now that you know a bit more about the different CPU coolers that are available and how they work, you’re almost ready to start shopping! But first, let’s go over some quick, helpful tips for choosing the best air and liquid CPU coolers out there.

Before you start looking at cooler systems, you should check your other internal PC parts to find out how much heat they’re expected to produce while running at max capacity. You need to know how much heat you’re sinking and transferring away in order to decide how powerful of a cooling system you will need for your PC.

CPU coolers can get a bit expensive at the higher end of the product spectrum, and you wouldn’t want to spend $300 on your cooling system when you only need $50 worth of cooling power; or vice versa.

Some things to consider might include; clock frequency, circuit voltage and complexity, and the material that the circuits are made out of.
