Picking an AIO liquid cooler in Johannesburg comes down to radiator size, fan noise and socket support — here is how to choose one that actually fits your case and CPU.
Quick Answer
For most Johannesburg gaming PCs a 240mm AIO in the R1,800 to R3,200 band keeps a Ryzen 7 7800X3D or Core i7 under 80°C while staying quiet. Step up to a 360mm unit (R3,000 to R5,500) only for a Core i9-14900K or a small, hot case.

How big a radiator do you need
A 240mm AIO handles up to a 125W CPU comfortably, which covers the Ryzen 7 and Core i5/i7 chips most buyers run. For a Core i9-14900K or heavy all-core work, a 360mm radiator drops temperatures 6-10°C and lets fans spin slower and quieter. Always check your case's stated radiator support before ordering — mid-towers usually take 240mm up top and 360mm in front.
Noise, pump quality and warranty
A good AIO should idle near-silent; cheap pumps whine, so stick to reputable brands stocked with local warranty. Look for a pump rated for long service life and fans with PWM control so your motherboard can ramp them only when needed. Local warranty matters with liquid coolers because a pump failure should be an easy SA-side claim, not an overseas RMA.
Fitment checks before you buy
Confirm the socket bracket matches your CPU (AM5 for current Ryzen, LGA1700 for current Intel), check radiator thickness against your case, and leave clearance for RAM height if the radiator mounts up front. A 240mm unit needs roughly 280mm of case length for the radiator and fans.
FAQ
Is a 240mm AIO enough for a gaming PC?
Yes for the vast majority of builds. A quality 240mm AIO keeps a Ryzen 7 7800X3D or Core i7 below 80°C under gaming load, which is all you need for stable boost clocks.
How much does a good AIO cost in Johannesburg?
Budget R1,800 to R3,200 for a solid 240mm unit and R3,000 to R5,500 for a 360mm at Evetech. Spending more mainly buys quieter fans and RGB, not lower temperatures.
Do AIO coolers need maintenance?
Modern sealed AIOs are maintenance-free for their warranty life — there is no topping up. Just keep the radiator dust-free and you are set for years.
