Quick Answer

The best AIO liquid coolers currently stocked at Evetech range from R1,200 for a 120mm single-fan unit to R3,800 for a 360mm triple-fan cooler with an LCD pump head. For most Ryzen 5 and Core i5 builds, a 240mm AIO at roughly R1,800–R2,200 keeps thermals under 75°C under sustained load without the noise of a large air tower.

Radiator Size: Matching AIO to Your CPU

Radiator size is the single most important spec when selecting an AIO. A 120mm AIO handles CPUs with a TDP up to 65W adequately — think Ryzen 5 5600 or Core i5-12400. A 240mm radiator is the sweet spot for 125W CPUs like the Ryzen 7 7700X or Core i7-13700K, keeping junction temps below 80°C during hour-long render sessions. If you're running a Ryzen 9 7950X or Core i9-14900K at full tilt, a 360mm AIO is the minimum — anything smaller and you'll hit thermal throttle within minutes. Evetech stocks 240mm and 360mm AIOs from Lian Li, NZXT, and Deepcool.

Compatibility Checks Before You Buy

Socket compatibility is non-negotiable. AMD AM5 and AM4, Intel LGA1700 and LGA1851 are all supported by current AIO brackets, but confirm the box includes your socket bracket before adding to cart. Case clearance is equally important: a 360mm radiator needs a top or front mount with at least 360mm of mounting rail — check your ATX case specs. Pump head height matters too, especially in mid-tower cases with tall VRM heatsinks near the CPU socket.

Noise, Warranty, and SA-Specific Considerations

AIO pump noise is rated in dBA — a quality unit runs at 20–28 dBA under load, quieter than most air coolers at speed. Evetech's AIO range carries standard SA warranty coverage. For buyers in Bedfordview, click-and-collect from the Johannesburg East warehouse is available, or next-business-day courier to East Rand addresses applies to most in-stock items.

FAQ

How long does an AIO liquid cooler last?

Most quality AIOs are rated for 50,000–70,000 hours of pump life, which translates to 5–8 years of daily use. The coolant gradually loses effectiveness over time, but visible performance degradation is rare before the 5-year mark. Evetech-stocked brands include warranty periods of 2–5 years depending on the model tier.

Is an AIO better than an air cooler for a remote-work PC?

For quiet operation an AIO typically wins on noise at equivalent thermal performance — a 240mm AIO runs 3–5 dBA quieter than a comparable dual-tower air cooler under load. However, a premium air cooler like the Deepcool AK620 (currently stocked at Evetech) at around R900 can match a 240mm AIO thermally for CPUs under 125W TDP while being more reliable long-term.

Can I fit a 360mm AIO in a mid-tower case?

It depends on the case. Most full-tower ATX cases support top-mounted 360mm radiators. Mid-towers vary — some support front 360mm mounting, others max out at 280mm. Check the case specification for "max radiator size" before ordering the AIO. Evetech product pages list compatible radiator sizes for their stocked cases.

TIP

an AIO, mount the pump head slightly below the radiator if possible — this prevents air pockets from collecting near the pump and extends pump lifespan. If the radiator must go at the front, angle the tubes downward from the pump head.
