Quick Answer
A 360mm radiator measures 394mm by 120mm by 27mm, plus fan thickness, and requires a case with a dedicated top or front mount rated for that size. Not every case listed as "360mm ready" fits a radiator with fans attached, so verify the mount dimensions, clearance to the motherboard, and fan screw positions before purchasing either the case or the AIO.
Measuring Radiator Fitment in Your Case 📐
Case specifications often quote bare radiator support, not including fan thickness. A 360mm radiator with three 25mm fans attached is approximately 55mm deep in total. For a top mount you need that 55mm of space between the case roof and the highest component on your motherboard, typically the RAM or VRM heatsink fin stack.
If your board has tall DDR5 heat spreaders above 45mm, a top-mounted 360mm radiator may require low-profile RAM or a front mount instead. Front-mounted 360mm radiators have more clearance from the motherboard but the front panel gap between the mesh and inner frame must accommodate at least 65mm for the fan-plus-rad stack.
Case Recommendations in SA 🎮
Several cases reliably stocked at Evetech fit 360mm AIOs with full fans attached. The Lian Li PC-O11 Dynamic EVO supports a 360mm side mount with 65mm of clearance, priced at approximately R3,000 to R3,500. The Phanteks P600S handles a front 360mm mount with 70mm clearance. For tighter budgets, the Deepcool CH510 Mesh Digital in the R900 to R1,400 range supports 360mm top mounts with standard VRM clearance on mainstream AM5 builds.
Avoiding Compatibility Pitfalls for SA Buyers 🔧
Some locally stocked cases are older inventory, so confirm the unit is a current production revision as 360mm support was sometimes added in mid-cycle updates.
Cable routing matters: a front 360mm radiator blocks easy access to front panel USB headers, so plan routing before building. Also verify your case's top panel supports the weight of a 360mm radiator with three fans, roughly 900g to 1.1kg total. Low-cost cases with thin steel top panels can develop flex over time, particularly for builds moved between LAN venues at gaming club events around South Africa.
Check Motherboard VRM Height Before Top-Mounting ⚡
The most common reason a 360mm radiator does not fit a compatible case is an unaccounted VRM heatsink height. Download the technical drawing PDF for your motherboard model and note the tallest VRM fin stack height before calculating top-mount clearance. Most manufacturers include this dimension in the board's technical spec sheet.
FAQ
Can I use a 360mm AIO in a micro-ATX case?
Rarely. Most mATX cases cap at 240mm due to internal depth constraints. A 360mm AIO build realistically requires a mid-tower ATX case at minimum.
Does a front-mounted radiator reduce case storage space?
Yes. A front 360mm radiator and fan stack occupies the space where drive bays would normally sit. Many current cases relocate drives to the rear of the case behind the motherboard tray to compensate.
How much does a quality 360mm-compatible mid-tower cost in SA?
Quality mid-towers with confirmed 360mm compatibility cost between R1,200 and R4,500 at Evetech. Cases in the R2,000 to R3,500 range offer reinforced radiator mounts, tempered glass panels, and dual-chamber layouts.
Shopping for a case that fits your 360mm AIO?
Evetech stocks a wide range of mid-tower and full-tower PC cases with confirmed 360mm radiator support across a range of budgets.
