How to Install All-in-One AIO: Step-by-Step

Quick Answer

Installing an All-in-One (AIO) liquid cooler in SA takes about 30-45 minutes: mount the backplate, screw the pump head onto the CPU with thermal paste, fit the radiator and fans into your case, then plug the pump into the AIO header and fans into CPU_FAN. Almost every AIO sold locally ships with brackets for both AM5 and LGA1700, so the same kit works across builds.

What You Need Before You Start

Grab your AIO box, a Phillips screwdriver, a clean microfibre cloth and 99% isopropyl alcohol if you're swapping from an old cooler. Most kits at Evetech, like the Corsair iCUE H100i, NZXT Kraken and MSI MAG CoreLiquid, ship with pre-applied thermal paste and the right brackets for AM4, AM5 and LGA1700 sockets. Check your case clearance: a 240mm rad needs a top or front mount with 280-300mm of free space, and a 360mm rad demands a roomier mid-tower like a Lian Li Lancool or Corsair 4000D. With loadshedding still a daily reality, also make sure your UPS can carry the pump's draw plus your PC under load, you don't want the pump cycling off mid-render.

Step-by-Step Installation Walkthrough

Start by laying the case on its side and removing both side panels. Pull the radiator out of the AIO box, then attach your fans to the radiator using the long screws supplied, with the airflow arrow pointing into the rad if you're using a top-mount push configuration. Slide the radiator into your chosen position and secure it with the short screws so they don't pierce the rad fins. Next, fit the AM5 or LGA1700 backplate behind the motherboard, then screw the standoffs in from the front. Apply a pea-sized blob of thermal paste if your pump head doesn't have it pre-applied, lower the pump straight down (don't twist) and tighten the four mounting nuts in a diagonal cross pattern. Plug the pump's 3-pin into AIO_PUMP or CPU_OPT at full speed, daisy-chain the fans into a splitter, then connect to CPU_FAN. Boot into BIOS and confirm pump RPM reads above 2000 before you load Windows.

Common Mistakes SA Builders Make

Three things trip up first-timers locally. One: mounting the radiator with tubes pointing up at the top of the case. Air gets trapped in the pump, you'll hear a gurgling noise, and the cooler underperforms. Always orient tubes lower than the highest point of the rad. Two: skipping the BIOS check. If the pump header is set to "Silent" or PWM control, your pump can throttle to 40% and let temps spike past 90C in Cinebench. Set the AIO_PUMP header to "Full Speed" or 100% DC mode. Three: overtightening the mounting nuts. The Asetek and CoolerMaster cold plates only need firm finger-tight plus a quarter turn with the screwdriver, going further can warp the IHS contact and actually hurt thermals.

Picking the Right AIO for Your Build

For Ryzen 7 9700X or Core Ultra 7 builds, a 240mm AIO around R2,500 is plenty. Step up to 280mm or 360mm (R3,500-R5,500 range at Evetech) for Ryzen 9 9950X3D, Core Ultra 9 285K, or any heavy streaming and rendering rig. ARGB models like the NZXT Kraken Elite with the LCD screen sit closer to R6,000 but pair beautifully with a glass-side case. Delivery is typically 2-3 working days countrywide and longer to the Eastern Cape coast, so plan your build weekend accordingly.

Frequently Asked Questions

Do AIO coolers leak in SA's climate?

Modern sealed AIOs from Corsair, NZXT, MSI and DeepCool are factory-filled and pressure tested. Leak rates are vanishingly low across the 5-6 year warranty period, and SA's relatively dry inland climate (Gauteng, Free State) is actually kinder to AIOs than humid coastal builds.

Which AIO size do I need for a Ryzen 7 9800X3D?

A 240mm AIO will keep the 9800X3D under 75C in gaming. If you're also doing video editing or running an OC, jump to a 280mm or 360mm rad to give yourself thermal headroom. Cases like the Corsair 4000D and NZXT H7 take 360mm rads at the front comfortably.

Can I reuse an AIO when upgrading my CPU?

Yes, all current AIOs ship with AM5 and LGA1700 brackets in the box. Pop off the old socket bracket, clip on the new one, clean the cold plate with isopropyl, apply fresh paste and remount. The pump and rad have a 5-6 year service life, so reusing across two builds is normal.
