The best CPU cooler for you depends on your processor's heat output, your case clearance and how much noise you'll tolerate. We've tested air and liquid coolers, and ranked them on measured temperatures, noise and value, not marketing claims.
Here are our picks across budget, mid-range and premium, then how to choose air versus liquid.
How we picked
We measure temperatures under sustained load and the noise to get there, check case and RAM clearance, and weigh value. A cooler that holds a chip in check quietly beats a flashy one that runs loud, and air is often the smarter buy below the top tier.
Best budget cooler: Thermalright Peerless Assassin 120 SE
The Peerless Assassin is the value legend: twin-tower air cooling that handles mid and even upper-range chips for a tiny price. Unless you have a clearance issue, start here.
Mid-range tierBest mid-range cooler: ARCTIC Liquid Freezer III Pro 360
For hot, high-core CPUs, a 360mm AIO keeps temperatures and noise down. The Liquid Freezer III is the value pick in liquid cooling, strong performance without the premium-brand markup.
Best premium air cooler: Noctua NH-U14S
Noctua's NH-U14S is the premium air choice: excellent cooling, famously quiet, and built to outlast several builds. No pump to fail, no liquid to worry about. The connoisseur's pick.
Decision frameworkHow to choose the right cooler
- Match the CPU. Check the cooler's rated TDP against your chip. High-core flagships run hot and need a strong air tower or a 280/360mm AIO.
- Air or liquid. Air is cheaper, simpler and reliable. Liquid (AIO) cools the hottest chips and frees space around the socket, at higher cost.
- Clearance. Check cooler height against your case, and tower clearance against tall RAM. AIOs need a radiator mount your case supports.
- Noise. Bigger heatsinks and radiators move air slower and quieter. Quiet fans make a real difference day to day.
- Don't forget paste. A decent thermal paste and a clean mount matter as much as the cooler itself.
