2. be quiet! Pure Loop 2 FX 360mm CPU Liquid Cooler
Best for: Spacious gaming PCs with ARGB lighting
At around $60, the be quiet! Pure Loop 2 FX 360mm is a CPU liquid cooler for modern Intel and AMD systems. Its 360mm radiator pairs with three 120mm Light Wings PWM fans, giving users three airflow sources instead of one or two. Compatibility covers Intel sockets 1700, 1200, 2066, 1150, 1151, 1155, and 2011(-3) Square ILM. AMD support includes AM4 and AM5, along with Ryzen 3, 5, 7, and 9 processors.
The pump uses a doubly decoupled design to reduce vibration and operating noise. That matters in a gaming desktop that sits near a desk or microphone. Each fan includes ARGB lighting, while the included ARGB-PWM hub can connect and synchronize up to six ARGB parts and PWM fans. This gives the cooler a cleaner cable setup than managing every fan separately. The main concern is physical size. A 360mm radiator needs a compatible case with enough mounting room, so measure the top or front panel before ordering. At this price, it offers a strong feature mix, but buyers should still confirm clearance around the motherboard and memory.
Pros
- Three 120mm PWM fans provide airflow across the 360mm radiator.
- The isolated pump design helps limit vibration and noise.
- The hub supports up to six ARGB components and PWM fans.
Cons
- The 360mm radiator will not fit many compact or mid-size cases.

Buying Guide
Cooling capacity matters most for the Ryzen 9 3950X. Its 16 cores and 105W TDP can produce sustained heat during rendering, compiling, and other heavy workloads.
- Thermal rating: Choose a tower cooler with a stated capacity of at least 150W, or a liquid model with a 240mm radiator or larger. These options provide more headroom than compact coolers.
- Socket support: Confirm the package includes an AMD AM4 mounting kit. The 3950X uses AM4, and some older or clearance-stocked coolers may require a separate bracket.
- Physical clearance: Measure your case before buying. Many dual-tower air coolers stand 155 to 165mm tall, while radiators need roughly 240mm of mounting space plus fan clearance.
- Memory and graphics clearance: A front fan can cover tall RAM modules. Look for adjustable fans or an offset design, especially with memory taller than 40mm.
- Noise and price: For quieter operation, seek a cooler rated below 30dBA or an AIO with a controllable pump. Expect about $50 to $100 for a strong air cooler and $80 to $150 for a 240mm AIO.
If you cannot optimize everything, prioritize cooling capacity and case compatibility first.
Frequently Asked Questions
How much cooling does a Ryzen 9 3950X need?
A 240mm or 280mm liquid cooler, or a large dual-tower air cooler, is the right class for a Ryzen 9 3950X. Its 105W rated thermal design power is manageable, but Precision Boost Overdrive can raise heat output. Check AM4 support and case clearance before buying.
What air cooler works well with the Ryzen 9 3950X?
A dual-tower air cooler is the strongest simple choice for most stock or mildly tuned 3950X systems. Models such as the Noctua NH-D15 support AM4 and measure about 165 mm tall, so verify your case limit. Also check RAM height, since front-fan clearance can restrict tall modules.
Can a 120mm AIO cool a Ryzen 9 3950X?
Yes, a 120mm liquid cooler can run a Ryzen 9 3950X, but it is less suitable for long rendering or compiling sessions. A 240mm radiator gives more surface area, while a 280mm unit uses two 140mm fans and may reduce fan noise at similar workloads.
Are liquid coolers better than air coolers for this processor?
Liquid coolers are not automatically better, because a good dual-tower heatsink can match many 240mm all-in-one units. Choose a 240mm or 280mm AIO for sustained heavy loads or a compact case, but account for pump noise, radiator placement, and a shorter warranty than some air coolers.
Conclusion
The AMD Ryzen 9 3950X Desktop Processor is the top recommendation for buyers who want a powerful, high-core-count desktop platform and plan to pair it with a cooler built for sustained workloads. If your priority is quieter operation, easier installation, or lower upfront cost, choose a dependable tower air cooler instead of a liquid model, provided it supports the processor’s heat output and your case layout. Before buying, double-check the cooler’s height or radiator size, AM4 compatibility, the included mounting hardware and fan quantity, clearance around your memory, and the current price, since listings and bundles can change. A quick check can prevent fit problems and unexpected extra purchases later.
