Cooler Master CK720: Two-minute review
I’m sure I’m not alone when I say that the top gaming keyboard manufacturers really need to throw their hats in the keyboard modding ring. They have been but the going was slow, withRazerreleasing its Razer PBT keycap upgrade sets and coiled cables back in 2020, Roccat just rolling out the first keyboard in its popular Vulcan line with removable keycaps in 2022, and HyperX only launching its customized keycaps this year.
Luckily, some of thebest gaming keyboardbrands are starting to pick up the pace, especially with the release of the Cooler Master CK720, CM’s first foray into the hot-swappable, mod-friendly enthusiast keyboard game. It isn’t the first one to get there, with theCorsair K70 Pro Mini Wirelesshitting the shelves a few months earlier.
However, it is a promising early attempt that makes me look forward to what comes next. And, I probably would rate it as one of thebest mechanical keyboardsfor beginners who want to get intokeyboard modding.
This is a 65% keyboard, which in my opinion is the perfect compromise. It keeps some of the vital dedicated keys – like the arrow keys – while maintaining a small footprint that’s ideal for smaller or nomadic setups. And, while it isn’t the lightest I’ve tested, it won’t be a struggle lugging it around in your backpack if you want to bring it to the office, even if that office is at a resort in Hawaii.
Though it’s a mostly simple-looking keyboard, many of the Cooler Master CK720’s parts are customizable or replaceable. It’s hot-swappable, meaning you can pull out the existing switches with a switch puller and replace them with other switches.
Naturally, its PBT doubleshot keycaps, available in black and white, are removable and replaceable as well; so is its cable so you can switch it out to your favorite coiled cable as I did. In fact, so is its top plate, although removing that one – you have to pull a small, hidden lever to loosen and remove it – can be such a pain it’s almost not worth it. Cooler Master currently does not sell top plates in different colors and designs anyway.
Remove the top plate, however, and you’ll be able to access the rest of the keyboard parts. Not that you’d want to as CM has taken pains to make it a well-built board. It’s fitted with the brand’s new pre-lubed stabilizers as well as two separate silicone dampening pads (one on the PCB and one on the bottom cover).
There’s a three-way multi-function knob, also known as a rotary encoder, at the top right corner that works with media controls by default but whose functions can be remapped on the MasterPlus software. You can use it to cycle through RGB lighting effects, as navigation keys, to access macros, and more.
While we’re on the subject, installing MasterPlus opens the keyboard up to a whole world of customizations. Being a mini keyboard, it already comes with on-the-fly shortcuts, but the software just gives you a whole lot more control over your per-key lighting, remapping, and macros. I highly recommend downloading it.
Without it, the Cooler Master CK720 is already an incredible gaming keyboard. Its standard 1,000Hz polling rate was more than enough to keep up with games likeCyberpunk 2077and battling rot monsters and bosses inKena: Bridge of Spiritsduring my testing. Plus, I didn’t experience any latency due to its wired connectivity.
As great as it is for gaming, it’s also an incredible keyboard for productivity. In fact, as far as enjoying a satisfying typing experience, this is one of thebest keyboardsI’ve ever used. That’s thanks in part to the Kailh Box V2 red switches it’s fitted with (both white and brown switch variants are also available) as well as due to the stabilizers inside. As a result, those keys not only deliver that satisfying linear feel, but are also very smooth and stable.
Mech keys, especially clicky ones, tend to be loud, but the addition of the two dampening pads here are somewhat successful at minimizing the noise. While I have used much quieter keyboards, the CK720 isn’t too bad either. I just wish that my linear red version delivered a more thocky sound, but what I’m getting is something between that and a clacky sound. That’s not a deal-breakers per se, but if you’re more discerning about your keyboard’s sound profile, you’ll want to do a sound test first.
Cooler Master CK720: Price & availability
The Cooler Master CK720’s price tag is about on par with many enthusiast mech keyboards in its class. It’ll set you back $115.99 / £93.07 / AU$172.67, which is probably more than most people would pay for a keyboard but is just about what most enthusiasts would spend on a new keyboard to add to their collection.
In thebest mini gaming keyboardsrealm, however, it’s actually cheaper than the competition. The wirelessRazer BlackWidow V3 Mini Hyperspeed, for example, is an eye-watering $199.99 / £189.99 / AU$329.95 while the wiredRoccat Vulcan II Miniwill set you back $149.99 / £129.99 / AU$259.95. Both have a mini layout; unlike the CK720, neither is hot-swappable.
The CK720 is now readily available in the US, the UK, and Australia.

How I tested the Cooler Master CK720
I tested the Cooler Master CK720 for a few weeks, using it as my gaming keyboard and my main keyboard for work. I tested it with games likeCyberpunk 2077, Kena: Bridge of Spirits,andHogwarts Legacy.I also used it to compose emails and write articles.
I made sure to mod it to see how easy it is to customize, removing the keycaps and switches as well as top plate and replacing the former two with keycaps and switches from my collection.
As a keyboard enthusiast, I own a small collection of mechanical keyboards, many of them hot-swappable and I customize when I find the time. I’ve also been testing keyboards, from productivity ones to gaming options, for years now, even before I joined the TechRadar Editorial team.
