Ever since I tested it last year, the Thermalright Peerless Assassin 120 SE has been my go-to recommendation for anyone seeking a sensible, low-cost, yet still powerful CPU cooler. Making this already fantastic-value cooler even more appealing right now is a 15% off deal on Amazon, bringing it down to its lowest price yet. If you're rocking a CPU with fewer than eight cores - yes, even the brand new AMD Ryzen 7 9850X3D - the Thermalright Peerless Assassin 120 SE will cool it just fine, and do so quietly. That's why it's my "best for most" choice on our best CPU cooler guide. Compatible with basically every recent AMD and Intel CPU right out of the box, the Thermalright Peerless Assassin 120 SE will be a suitable upgrade for most PCs.
