The AR07 is a solid looking cooler with quiet operation. Silverstone gives the buyer a unique budget option for the CPU, but cooling performance isn't as high as expected. This unit would be a solid upgrade to low-end stock cooler for sure though.
Enermax delivers a great RGB filled liquid cooler with the LIQFusion 240. While the lighting is fantastic, the unit doesn't sacrifice cooling performance for aesthetic flair. RGB may not be for everyone, but if you want addressable control, the LIQFusion should be at the top of your list.
Arctic offers a great performing CPU cooler that has a variety of static color choices in the Freezer 33 eSports Edition. It offers a wide range of compatibility, working with most processors from Intel and AMD. The install is tedious at points, but the style is hard to beat with other coolers in the same price range.
CLCs are overwhelming used for CPUs, but what if they are better suited for GPUs? The Arctic Liquid Freezer 120 proves it has excellent ability to keep temperatures low during intensive gaming sessions, at minimal noise as well. What it lacks in aesthetics it makes up for by far in price.
Sometimes looks are more important than performance, but Raijintek doesn't force you to make that trade. The Orcus 240 is an excellent CPU cooler, and it brings an innovative design to the CLC market. Unfortunately, it doesn't have individually addressable RGB LEDs yet.
Noctua is long renowned for having silent fans. They also have beige colors. Chromax changes everything to add a much needed stylish flair to their heat sink and fan lineup. You won't find RGB lighting, but the choices of blue, green, red, yellow, black and white accessories adds a lot.
