The Noctua NH-D15 is one of the best CPU coolers you can buy in 2019 simply because it performs just as well as – if not better – than some liquid coolers, while costing a fraction of the price. You might not be too familiar with Noctua’s name, as they’re relatively small in the CPU cooler world, but its business is revolves around designing coolers, so you know that when you buy one of their products, you’re getting a product by people who really know their craft. On top of delivering a fantastic cooling performance, the NH-D15 is nearly silent as well.
Cooler Master’s Hyper 212 CPU RGB cooler is back with a vengeance, and sporting a sleek gun-metal black brushed aluminum finish to boot. It’s not only jet black look that’s upping this CPU cooler’s cool factor – though it does help what with that aluminum top cover and nickel plated jet black fins to complete the look. It’s also easily one of the best CPU coolers on the market with its stacked fin array that ensures least airflow resistance, four heat pipes that boast Direct Contact Technology to better battle the heat, and a wide speed range for fine-tuning cooling performance and silent operation.
Noctua is an Austrian manufacturer that does one thing, and one thing only: make the best CPU coolers and fans. What this means is that even though the Noctua NH-L9 is tiny, it is still more than capable of insane cooling with no compromises. This is a fantastic cooler for anyone with a smaller build, or even if you’re using a ton of large components, and you’re not comfortable with liquid cooling.
Whether you’re going for 360MM or 280MM, the NZXT Kraken Z-3 is an excellent choice if you’re looking for liquid cooling. First of all, thanks to its vibrant 2.36-inch LCD screen that’s capable of displaying 24-bit color, this liquid cooler allows total customization so you can fine-tune settings as well as display your favorite images and animated gifs. More importantly, it delivers impressive liquid cooling performance and is easy to install.
The Corsair iCUE H115i Elite Capellix continues Corsair’s tradition of outstanding liquid coolers. It couples excellent cooling, thanks to its split-flow copper cold plate and its low-noise centrifugal pump, with bright RGB lighting, due to the use of Capellix LEDs. And, the RGB lighting is, in true Corsair style, customizable through the company’s proprietary iCue software. If you want a powerful liquid cooling system that looks good too, the Corsair iCUE H115i Elite is a perfect choice.
With the Cooler Master MasterLiquid ML240P Mirage in your gaming rig, you won’t only end up playing for hours on end without worrying about thermal throttling or overheating. You might just have an hour or so admiring your CPU, especially if you have one of those glass-window cases, as this CPU cooler is indeed hypnotically pretty. It’s mostly thanks to its transparent pump design that lets you see the impeller spinning while bathed in different RGB lighting, like a colorful spinning wheel at a funhouse. Performance-wise, it definitely deserves a spot in our best CPU coolers list, with its PPS+ glass fiber housing and nozzle that provides temperature and liquid resistance, EPDM rubber O-Ring that helps eliminate liquid emission, and a low-resistance radiator that increases flow rate, heat exchange efficiency and cooling performance.
There isn’t a single component that can’t be improved through RGB, and Cooler Master is well aware – jumping on the RGB bandwagon with the MasterLIquid ML 120R RGB. What’s more, it integrates some of the first addressable LEDs seen on a liquid cooler. This all-in-one liquid cooling solution isn’t just about aesthetics – it features an oxidation-free pump and an efficient radiator. This means that not only will it last longer – but it’ll keep your CPU cooler, and all without giving up too much case real estate, which is why it’s made our best CPU coolers list.
You’re getting your cool plate, radiator, and pump in one with the Arctic Liquid Freezer II 120, but that’s not all. Its pump clocks down to consume 80% less power and produce much less noise when cooling isn’t vital, and its water loop is practically maintenance-free, sealed with fiber-reinforced EPDM tubing. Plus, it’s easy to mount and very affordable, making it among the best value CPU coolers in the market today.
Even if your budget will allow you to really go all-out on serious liquid cooling solutions, if you have a smaller PC case, you’ll likely not have enough space. That’s where something like the Corsair Hydro H5 SF comes into play. Even on the smallest PC cases, you’re able to use this CPU cooler to keep your CPU chilled, even if you have some beastly overclocks happening. Plus, because it’s a closed-loop, you don’t even need to worry about maintenance. Set it up, and let it do its thing – you won’t be disappointed.
Rounding out our best CPU coolers list is the NoFan CR-95C. You’ve probably never heard of NoFan – unless you’re already neck-deep into the rabbit hole that is silent PC assembly. The South Korean component company specializes in helping enthusiasts reach that 0dBA silent sweet spot. In doing so, of course, will severely limit your set-up in terms of power, with its CR-95C fanless solution being limited incompatibility to processors whose TDP fall below 95W. Still, the NoFan CR-95C is worth a shot if you want to build a low-power computer that completely blends into the background.
