Quick Answer
Before buying a 360mm AIO, verify your CPU socket (AM5, LGA1851, LGA1700, or AM4) is on the cooler's compatibility list and confirm your case supports a 360mm radiator at the front or top panel. Skipping either check is the most common way SA builders end up with a cooler they cannot install.
CPU Socket Checklist for 2026 SA Builds 🔧
The four sockets you are most likely to encounter in current South African gaming and workstation builds are: AMD AM5 (Ryzen 7000 and 9000 series), Intel LGA1851 (Core Ultra 200 series), Intel LGA1700 (12th to 14th Gen Core), and AMD AM4 (Ryzen 5000 and below). Each socket uses a different mounting hole pattern and in most cases a different backplate. AM5 requires a specific backplate because AMD changed the mounting hardware from AM4. LGA1851 shares hole spacing with LGA1700 at 78mm x 78mm, so many current 360mm AIOs support both with the same bracket, but confirm this explicitly. AM4 coolers require an adapter kit to work on AM5. The safest approach is to find the AIO product page, download the user manual, and locate the supported socket table before purchasing.
Case Size Requirements for 360mm Radiators 🖥️
A standard 360mm radiator measures 394mm x 120mm x 27mm (length x width x thickness) and requires a case mounting point of at least 400mm in length. Full-tower cases universally support 360mm front and top mounting. Large mid-towers (like the Fractal Design Meshify 2, Phanteks Eclipse P500A, and similar) support 360mm front mounting and often top mounting. Compact mid-towers and mATX cases are where problems arise. Many micro-ATX cases list 360mm front support but have tight tolerances that conflict with the pump head or GPU card length. Before buying, note your case's maximum supported radiator lengths at each mounting position from the manufacturer spec sheet, not from third-party reviews that may reference different variants.
Clearance Factors Beyond Radiator Length 💡
Radiator length is only one measurement. Radiator thickness matters if you want to stack a fan on the opposite side of the radiator for a push-pull configuration: total depth in that scenario is around 52 to 54mm. Pump head height can conflict with tall RAM modules in top-mount configurations, especially in cases where the socket is close to the top panel. RAM modules taller than 45mm can block certain pump heads when the radiator is mounted at the top.
Measure Top Panel to Socket Distance Before Ordering ⚡
Use a ruler to measure from the top panel interior surface straight down to the centre of your CPU socket. Compare this to the pump head height listed in the AIO spec sheet. If the clearance is less than 5mm above the pump head, look for a slimmer pump design or switch to front-mounting the radiator instead.
FAQ
Can a 360mm AIO physically damage a motherboard if mounted incorrectly?
Over-tightening the mounting screws can crack the PCB or damage the IHS solder joints on Intel CPUs. Follow the torque instructions in the cooler manual and tighten screws in a diagonal pattern to even the pressure. Never tighten fully on one side before starting the other.
Do mATX motherboards support 360mm AIO pump heads?
The pump head mounts to the CPU socket, not the motherboard form factor. An mATX board with an AM5 socket uses the same AM5 mounting pattern as a full ATX board. The challenge with mATX builds is case size, not motherboard compatibility.
What case form factors support 360mm AIOs in South Africa?
Full-tower and large mid-tower ATX cases are the most reliably compatible. Popular SA choices include the Phanteks Eclipse series, Lian Li cases, Fractal Design Meshify and Define series, and DeepCool cases from R1,800 to R3,500 at Evetech. Always cross-reference the specific case model's radiator support spec.
Not sure if your case supports a 360mm AIO?
Evetech's product pages list radiator support specs for cases and coolers side by side. Browse the CPU cooler and case categories to match your radiator size before purchasing.
