What Stands Out
Superior Cooling
The 420mm radiator combined with three 140mm fans ensures exceptional heat dissipation, maintaining optimal CPU temperatures even during intense gaming sessions or heavy workloads.
PWM Pump
The advanced PWM pump operates quietly while dynamically adjusting speed, ensuring efficient cooling performance and reduced noise levels, making it perfect for gamers and professionals alike.
Comprehensive Compatibility
This cooler supports both AMD AM5/AM4 and Intel LGA1851/1700 sockets, providing versatile compatibility for a wide range of processors, ensuring seamless integration with most builds.
Product Details
- CONTACT FRAME FOR INTEL LGA1851 | LGA1700: Optimized contact pressure distribution for longer CPU life and better heat dissipation
- ARCTIC's P14 PRO FAN: More power at any speed - more powerful and quieter than the P14, especially at low speeds. Higher maximum speed for optimal cooling performance under high load
- NATIVE OFFSET MOUNTING FOR INTEL AND AMD: Shifting the cold plate center towards the CPU hotspot ensures more efficient heat transfer
- INTEGRATED VRM FAN: PWM-controlled fan that lowers the temperature of the voltage converters and thus ensures reliable performance
- INTEGRATED CABLE MANAGEMENT: The PWM cables of the radiator fans are integrated in the sheathing of the hoses so that only a single visible cable is connected to the motherboard
