Introduction
For gamers looking to build a gaming PC full of power-hungry components, finding a solid cooling system is crucial. Whilst it’s easier for budget or mid-range builds to operate without a sufficient CPU cooler attached to it, high-end systems are bound to overheat if they’re lacking in the thermal regulation department.
Therefore, anyone looking to build a high-end gaming PC should be picking up a premium liquid CPU cooler in order to accompany it. But how much should you expect to pay for a cooling solutions that can support a high-end system? Here at GeekaWhat, we’d say you don’t need to spend any more than $300 to get a premium CPU cooler capable of keeping temperatures low.

3. ASUS ROG Strix LC II 360
👑 The best CPU cooler under $300 for stealth-lovers
Introduction
Moving onto the other end of the lighting scale, the ASUS ROG Strix LC II 360 presents a more reserved look that is ideal for stealth-lovers. Whilst this design does include a hint of RGB lighting on the pump head, the predominantly matte black colour-scheme means this CPU cooler will easily blend into the background on a black PC case. Despite the lack of vivid colours, the LC II 360 manages to create a futuristic design that will appeal to a large group of PC gamers.
In terms of performance, the LC II 360 competes with the best CPU coolers on the market thanks to the three fans capable of reaching speeds up to 2500RPM. In addition, the Asetek pump allows heat to be transferred away from the system quickly without making lots of noise in the process.

Affordable 360mm AIO: In a similar fashion to the previous entry on this list, the LC II 360 is available at a relatively low price point for a premium 360mm AIO cooler. Whilst it is still beyond the budget of most gamers, high-end builders can pick up this cooling solution to save some cash.
Things We Don’t Like
Lack of customisation: Due to the subtle approach taken with this cooler’s design, some customisation options have been limited compared to other premium options. For example, the lack of customisation on the LCD display makes it harder to track the temperature of your system.
Difficult to install: Like any liquid cooler with a large radiator, the installation process can be quite tricky due to the additional steps required to attach the fans and radiator pump. Therefore, less experience may need some help or should consider a different cooling solution.

However, the ASUS ROG Strix LC II 360 is one of the few premium designs to fill this quota for stealth-lovers. Plus, this AIO cooler also offers stellar thermal regulation at a price that is well below the $300 mark.

Do I Need a Large AIO CPU Cooler?
Ultimately, the size of the cooler you need depends on the type of PC you plan on building. Whilst a larger AIO cooler will generally lead to improved efficiency when transferring heat away from your system, there are plenty of factors that could make anything larger than a 240mm liquid CPU cooler less than ideal for your gaming PC.
First of all, the size of your build is a key factor when picking a CPU cooler, as your choices can be limited by other parts. The best example of this is the PC case because they need to have the capacity and infrastructure to support a certain radiator size if you are to use it for your system.
Therefore, anyone building a compact gaming PC will probably need to rule out a larger CPU cooler immediately, as most mini-ITX PC cases won’t have the space to support a 360mm or 420mm radiator. On the other hand, those rocking a full-tower chassis will need a larger AIO in order to fill the space and make their gaming rigs look less barebones.
Another key factor to consider is money. As is often the case with any purchase, there is a point where limiting funds to prevent overspending on a product is the sensible solution. Considering that larger coolers come with a heftier price tag, most budget or mid-range consumers are likely to be priced out of these more powerful coolers.
So before you decide to pick up a liquid CPU cooler with a large radiator such as 360mm or 420mm, be sure to consider whether these coolers will fit within your build, and if it fits within your budget.
Are Liquid CPU Coolers Difficult to Install?
One of the major concerns that novice PC builders have with liquid AIO coolers is the installation difficulty, as the additional steps compared to an air CPU cooler can be quite daunting. Whilst it is true that installing a liquid cooler is more complex than an air cooler, it is not as complicated as you may think. With the steps for attaching the water pump being very similar to the brackets on air coolers, as well as the process for installing the radiator being quite repetitive, putting a liquid CPU cooler into your system is not as bad as you might have first imagined.
On top of this, most manufacturers will try their best to streamline the installation process for their coolers. Not only does this make the product more appealing to consumers, but it also helps to avoid any manual errors, which can result to complications and damage to other components.

Frequently Asked Questions
What Liquid Coolers are Good for Overclocking?
Generally, larger CPU coolers such as 360mm or 420mm AIOs are the best options for those planning on overclocking their PC, as the additional fans and surface area allows it to dissipate more heat at once.
Do Old CPU Coolers Worth With a New CPU?
As long as they come with a bracket that supports the latest hardware, then an older CPU cooler will be able to attach to a new processor. Currently, any coolers with an LGA 1700 or AM5 bracket will be able to support both Intel 13th Gen and Ryzen 7000 CPUs.
Is $300 Enough for Money to Buy a CPU Cooler?
Definitely. $300 will be enough to pick up most liquid CPU coolers on the market, which means you’re lucky enough to have a wide range of options to choose from.
Do I Need RGB on a Liquid CPU Cooler?
No. RGB lighting on a CPU cooler is purely for aesthetic purposes, which means the performance of a cooler without RGB isn’t limited. Therefore, the inclusion of RGB on a design is up to personal preference.
