JONSBO NF-1  Memory-Chip Heatsink 4Pin PWM/5V 3Pin ARGB SYNC RAM Air AIO Fan Cooler with Dual 50mm Fan PC Memory Cooling Radiator 60-3600RPM for DDR2 DDR3 DDR4 DDR5 Cooling
Feature:
1. Efficient Cooling Performance: The ram cooler by Qiaosibo is designed to tackle the issue of high temperatures that often accompany DDR5 memory overclocking. With its active cooling vest design, it significantly improves memory cooling efficiency, enabling higher frequencies and more stable operation.
2. Sleek and Versatile Design: Measuring 120mm x 62mm x 28.1mm, the ram cooling fan comes in two color options: black and white. The black version is available in both standard and ARGB variants, while the white version only comes in ARGB. Its rectangular shape with ample cutouts allows compatibility with memories up to 54mm in height or an additional 8mm when using adapter copper pillars.
3. Active Cooling System: Equipped with two 50mm x 50mm x 20mm fans featuring hydraulic bearings, the ram memory cooler offers a 4-pin PWM/3-pin ARGB interface. The fan operates at a speed range of 600-3600 RPM±10%, ensuring quiet stability with a maximum noise level of 22.4 dB(A). The fans efficiently dissipate heat, contributing to a comfortable and silent environment for your system. Recommended for use with ATX motherboards in combination with liquid cooling.
4. ARGB Synchronization Lighting Effects: The ram radiator come with ARGB lighting effects that can be synchronized and controlled using major motherboard manufacturers' ARGB software. Enjoy a vibrant experience with up to 16.8 million programmable colors. Connect to for ASUS, MSI, Gigabyte, ASRock, and other motherboards with addressable 5V 3-pin ARGB interfaces to achieve software-controlled lighting synchronization and create custom lighting effects (ARGB version only).
5. Easy Installation and Usage: The memory-chip heatsink features a simple screw-in installation process, making it convenient for both initial setup and future maintenance. Players can replace the motherboard's fixed screws with the provided fixing screws, securing them into the corresponding motherboard holes. Then, fasten the cooler onto the fixed screws. The screws and female pillars on both sides allow for direct installation above the memory. However, compatibility is limited to a maximum height of 54mm.
