Cooler Master CMP 320 Review

Cooler Master CMP 320 Review Tony Smith

Summary: The Cooler Master CMP 320 provides room to move



The new CMP 320 is a mini-tower from Cooler Master that provides gamers with a smaller form-factor case that not only boasts premium aesthetics but RGB lighting with a tempered glass side to showcase the insides of your rig. It also ensures optimal thermals so you can fine-tune your rig (e.g. overclocking) for maximum performance on smaller motherboards that include the Mini ITX and Micro ATX boards.

In terms of cooling, the Cooler Master CMP 320 comes with two 120mm ARGB Fans plus a mesh filtration system to help in preventing dust build-up inside the case. Further, the case has enough room for an additional six fans plus radiator support (up to 240m) for liquid cooling options. Gamers will also appreciate that the CMP 320 can hold a graphics card up to 365mm, including a CPU cooler of up to 163.5mm. So as you can see, there is quite a bit of room to navigate and more importantly manage your components, all while keeping your case smaller.

The aesthetics of the Cooler Master CMP 320 is quite streamlined and definitely sets itself apart from the more mainstream cases with its angular edges. The left side of the case is tempered glass that allows you to look inside your rig and when matched with RGB lighting, it creates an impressive beast. Another highlight is that the case is a good size with plenty of room inside to move while building your dream machine. The case itself measures at 445.5 (Length) x 204 (Width) x 425mm (Height) with a 38.52L capacity.

We tested the Cooler Master CMP 320 with an Intel Core i9-13900K that included ASRock Z690 PHANTOM GAMING-ITX/TB4 motherboard, Cooler Master MasterLiquid PL240 Flux, Super Flower Leadex Platinum SE 1000W, WD_Black SN750 SE NVMe SSD, Kingston FURY Renegade DDR5 RGB Memory and a AMD Radeon RX 6800 XT. Needless to say these components easily fitted inside the case with no issues whatsoever. While smaller cases are excellent for those looking to minimise space, it does limit you to the motherboard size and my only complaint with this case is that the I/O panel only has one USB 3.2 Gen 1 Type-A port. However this is generally a shortfall of a large cohort of cases.


Final Thoughts?

The Cooler Master CMP 320 retails for around $99AUS (Feb 2023) and provides users with a mini tower that is capable to handle the latest components. It is also a good entry level case for those looking to upgrade or build a rig on a budget that also looks ‘gamer’, particularly when matched with RGB lighting that really stands out with its black colouring. Add in impressive cooling options and if you’re seeking that smaller form factor case, the Cooler Master CMP 320 is an overall winner plus 2-years warranty for peace of mind.
