Choosing The Best CPU Cooler - A Buyers Guide

This guide highlights the pros and cons of some of our best selling and great value CPU coolers, comparing some of the best CPU coolers for every budget.

A buyers guide to choosing the best CPU cooler.


Getting the most out of your brand-new AMD or Intel processor means you need to invest in adequate cooling. Not only will this prolong the life of your processor, but it will also ensure performance remains as high as possible when you’re thrashing around in Cyberpunk 2077 on Ultra settings… or exploring the open-world of Skyrim with all your weird and wonderful mods installed. For high-end gaming, a quality CPU cooler – either AIO water cooling or air cooling – is absolutely paramount.

Who Makes The Best CPU Cooler?

While there are some brands that are household names dominating the CPU cooler market, they don’t always represent the best value. Cooler Master, for example, have always nailed the performance aspect of CPU cooling, but have not necessarily made the grade in terms of value for money.

We tend to see brands like be quiet!, Corsair, NZXT, Noctua, and Lian Li appearing in benchmarks that also factor in low to mid-range budget, and making sure you get as much value in your investment as possible.

We’ll cover our most popular brands in terms of sales and customer satisfaction and check out how they stack up against each other in terms of value & performance.

Noctua CPU Coolers


Durable design
Runs quiet, even at higher RPM
Excellent customer service
Superior warranty (up to 6 years)
Smart design to reduce mechanical failure
Good power control
Low voltage
Redux range for lower budgets


Higher performance range is expensive compared to competition
Mostly basic & functional design (mostly brown)


Noctua have an enviable reputation among PC builders, enthusiasts and hobbyists, owing to their durable design and focus on ultra-quiet operation. Suitable for everything from gaming PC builds to high-end workstations, Noctua have designed a range that will meet all needs.

The Noctua Redux range of products are capable of delivering quiet performance at a lower price, being able to compete with manufacturers who have had this end of the market sewn up for some time. Companies like Cooler Master and NZXT have the purchasing power to bring down the overall cost of a CPU cooler, and for a long time, their dominance has been felt by brands such as Noctua.

By solidifying their place in the market through sheer performance, Noctua are now a trusted brand, and will feature in the most high-end gaming builds.

Cooler Master CPU Coolers

Cooler Master are a brand that need no introduction, but I get paid by the word, so I may as well, right? As a brand, Cooler Master have made a huge name in the PC case and fan categories, with their new AiO water cooling systems getting plenty of limelight in recent months, too. Regularly in the top ten lists of best CPU coolers, the Cooler Master secret sauce has seemingly been to intertwine themselves with high-end PC modding and system building. By having a name that is mentioned in the same breath as these cash cow sectors, the brand implies high quality and performance.

MSI CPU Coolers

MSI are the award-winning manufacturer you turn to when you want absolutely no compromise on product quality and durability. Usually there is a compromise on price when it comes to components, but MSI have constantly maintained their market share since 1986 by slotting products into every available budget window. MSI gaming laptops remain at the top for market share, with almost 20% of the market sewn up, which is no mean feat considering ASUS are bringing their laptops in a close second place with 15% of the market. The cooling in mobile technology is what separates the big players, and MSI have constantly been on the bleeding edge when it comes to cooling systems. This has now allowed them to step into the combative AiO cooling arena with ease.
