You can pair the block with various Alphacool NexXxos radiators depending on your case space. The 240mm model offers a standard footprint for reliable cooling. For tighter builds, the 120mm single fan or 280mm options provide high-density copper heat dissipation in compact sizes.
Are these alternatives compatible with Intel LGA 1700 sockets?
The Bykski block itself supports both LGA 1700 and LGA 1200 sockets. The listed Alphacool radiators are heat exchangers and do not have socket-specific compatibility. They work with any CPU block that uses standard tubing connections, allowing you to cool various Intel processors effectively.
What material are the recommended Alphacool radiators made from?
All the listed Alphacool NexXxos radiators use copper for their internal cores. This material provides dense thermal conductivity for efficient heat transfer. The copper construction is available in various sizes, ranging from small 40mm units to larger 280mm models, ensuring consistent performance across different loop configurations.
Can I use these radiators in a small form factor PC?
Yes, several options fit small builds. The 40mm, 60mm, 92mm, and 120mm radiators are designed for space-constrained cases. The 60mm model is specifically for tiny builds where larger radiators physically cannot fit. These compact copper radiators allow you to maintain effective cooling in minimal volume.
How much does the Bykski Intel CPU block weigh?
The Bykski Intel CPU Water Block weighs 1.5 pounds. Its dimensions are 12 inches in width, 7 inches in length, and 4 inches in height. This weight and size provide a stable mounting solution for Intel LGA 1200 processors while maximizing the surface area for heat absorption.
