Air vs Liquid Cooling

Air vs liquid cooling is an age-old argument that always comes into discussion when picking out a CPU cooler. Instead of arguing which is better I’ll instead argue the use-case for liquid cooling over an air cooler. Liquid coolers have become a more mainstream option for several consumers due to the increase in CPU performance, and the associated heat output.

If you were to look back at CPUs that were being released five or so years ago, you’d see a significant difference in clock speeds and total wattage output. Most older CPUs didn’t demand the need for a liquid cooler because the CPU thermals were easily dealt with by a decent air cooler. But, due to significant performance increases in the past few years, CPUs have become hotter and hotter. And if we look at overclocking, a practice whereby you run a CPU faster than its default speeds, the demand for more efficient coolers increases exponentially. This is clearly demonstrated by the boosting behaviour of AMD‘s latest Ryzen 7000 processors, where the fundamental design of the chip necessitates a good CPU cooler to handle the temperatures output.

Which Radiator Size Do I Need?

After you’ve determined a budget for your CPU cooler, you’ll next need to pick out a radiator size. There are a few main sizes, based around the standard 120mm and 240mm fan sizes.

120mm-based DesignsUse Case140mm-based DesignsUse Case
120mm– Budget systems
– Small form factor systems
– Fairly inefficient for cooling
140mm– Small form factor systems
– Less efficient than a 240mm design
240mm– Best mi-range option
– Widest variety of designs
280mm– Best compact option for high-end systems
360mm– Best high-end option
– High-end systems
420mm– Fairly Niche
– Very high-end Systems

We’d recommend

Intel Core i9 Series🔥🔥🔥🔥360mm or 420mm
AMD Ryzen 9 Series🔥🔥🔥🔥🔥360mm or 420mm

You’ll also need to take stock of which radiator sizes the case you have selected supports. Smaller form factor cases won’t support all radiator form factors, while some chassis will better accommodate 120mm-based designs, rather than the larger 140mm alternatives. Radiator support in a case might also impede on GPU clearance, something to be mindful when spec’ing your system for the first time.

Socket Compatibility

Another major point to touch upon is socket compatibility. Although most modern CPU coolers tend to have updated mounting hardware, not all coolers will be compatible with your choice of CPU. To avoid not having compatible components we’d recommend checking out the manufacturers website to ensure it supports your CPU socket.
