Three measurements decide whether a 360mm AIO goes into a case: the radiator space, the socket support and the fan clearance. Buyers usually check the socket first because it is printed on the box, and they discover the radiator or fan problem after the cooler arrives. This guide puts the three checks in the order that saves the most time, with a measurement for each one.

Quick Answer

Verify three things before buying a 360mm AIO: radiator mount space, socket support and fan clearance. The Antec Skeleton Matrix 360 White needs a 360mm mount, covers four sockets, and sells for R1,199 including VAT. Measure the mount and the clearances in millimetres before you order.

📏 Check the radiator space first

Start with the mount, because nothing else matters if the case has no 360mm slot. Measure the mount's length, which needs to be at least 360mm, and its depth behind the front or top panel. Its core is about 27mm deep, and the fan on the face adds roughly 25mm.

Many small cases, including mini-ITX and micro-ATX models, offer smaller mounts. Check the case's specification for a 360mm slot before you consider the cooler at all, because a smaller mount cannot take this radiator.

🔌 Confirm the socket support second

Once the mount is confirmed, match the board's socket. Among the sockets it fits are LGA 1851, LGA 1700, AM5 and AM4. Read the socket name from the board's specification, and make sure it sits on the cooler's list.

Socket support is the check that costs the most when it goes wrong, because the cooler and the board both have to be returned. Read the socket name twice before ordering.

🌀 Measure the fan clearance last

The fan sits on the radiator's outer face, so its clearance is measured from the fan's front to the nearest obstacle. Check the gap between the fan and the front panel or the top of the case, in millimetres. A tight gap cuts airflow, and a fan that touches a panel can rub.

Clearance matters inside the case too. Tall RAM heatsinks and the board's top edge crowd a top-mounted radiator, so measure that gap in millimetres. Compare it with your tallest RAM stick before you commit.

The CPU coolers category lists AIO options, and the mini-ITX and micro-ATX cases category shows small cases to check for mount space, and the mid-tower cases category shows cases that are more likely to offer a 360mm slot.

🧾 A short checklist before the order

Write the three checks on one sheet: the mount length and depth, the board's socket name, and the fan clearance to the front or top panel. Fill in the millimetres as you measure, and tick each line only when the figure clears the cooler's requirement, with at least 5mm to spare on every clearance.

Keep the sheet with the parts list, so each new part is checked against the measurements before it is ordered. A check that takes a few minutes now saves a return later.

📐 A worked check with real numbers

Take a 360mm mount with about 52mm of usable depth ahead of it. A 360mm radiator with a 27mm core and a 25mm fan needs about 52mm, so the check passes with no spare room. If the gap from the board to the radiator's underside is 50mm and the tallest RAM heatsink is 45mm, the clearance is 5mm. A 40mm heatsink on the same gap leaves 10mm. Write each figure down before you order, so the check is repeatable.

🛠️ What to do when one check fails

If the mount passes but the fan clearance comes up 10mm short, look at a case with a deeper front or top, or use the other mount position. A check that fails by a few millimetres is still a fail, so do not force the radiator into place. A 10mm shortfall is a cue to change the case, not the screws.

📦 Keep the measurements with the order

Note the 360mm mount length, the socket name and the fan clearance in millimetres, and keep them with the order reference. A return that cites a 10mm mismatch is easier to settle when the measurements were written down before the purchase.

Frequently Asked Questions

What does the radiator need in the case?

The case needs a slot at the front or top, deep enough for the radiator and fan. Measure both in millimetres.

Which CPU sockets can the Skeleton Matrix 360 mount on?

The sockets are LGA 1851, LGA 1700, AM5 and AM4. Match your board to one of them.

Why check the fan clearance?

A fan that sits too close to a panel cuts airflow and can rub, so measure the gap to the front or top before you order.

How much does the Skeleton Matrix 360 White cost?

It costs R1,199 including VAT.
