Heatsink Specs and Fit Comparison
socket compatibility
The Dynatron Copper LGA1156 Blower Heatsink targets older Intel desktop platforms. It supports the LGA1156 socket for i5 and i7 processors. The Dynatron B9 serves a different market segment entirely. It supports the FCLGA3647 square ILM socket for Intel Xeon CPUs. These sockets are not interchangeable. You must match the cooler to your motherboard socket type. Choosing the wrong one will prevent installation. This distinction is critical for system builders upgrading legacy servers or desktops.
system type
The Dynatron B9 is designed for 1U server chassis. Its low profile fits into tight rack-mounted environments. The Dynatron Copper LGA1156 Blower Heatsink is a standard desktop cooler. It uses a blower design to exhaust heat out of the case. It does not fit in 1U server racks. Your choice depends on your chassis form factor. If you are building a server, the B9 is the only option. For a desktop tower, the LGA1156 blower is suitable.
fan size
The Dynatron Copper LGA1156 Blower Heatsink includes a 3-inch fan. This small fan spins at high speeds to move air. The specifications list speeds up to 2600 RPM at 50% duty cycle. The Dynatron B9 does not list a specific fan size in the provided data. It is an active cooler, but the fan dimensions are missing. You cannot compare airflow capacity directly without the B9 fan specs. The LGA1156 model has clear blower fan metrics available for review.
build material
Both coolers use copper for thermal conductivity. The Dynatron Copper LGA1156 Blower Heatsink is a solid copper heat sink. The Dynatron B9 uses Copper1100 for the heatsink. It also features a vapor chamber base. Vapor chambers spread heat more evenly than solid copper bases. This can improve cooling efficiency in dense server environments. The B9 has a more advanced base construction. The LGA1156 model relies on traditional copper block design.
dimensions
The Dynatron Copper LGA1156 Blower Heatsink measures 3.35 x 3.21 x 1.12 inches. It is compact for a desktop blower cooler. The Dynatron B9 measures 93 x 90.5 x 28 mm. This converts to roughly 3.66 x 3.56 x 1.10 inches. The B9 is slightly wider and deeper. Both are low profile designs. The LGA1156 model is taller in some dimensions depending on orientation. Check your case clearance for both before purchasing. The B9 is optimized for 1U height constraints.

No, you cannot use the Dynatron B9 on a standard desktop motherboard. This cooler is designed specifically for the FCLGA3647 square ILM socket found in server racks. It is built for 1U server environments. The Dynatron Copper LGA1156 Blower Heatsink supports the LGA1156 socket for desktop i5 and i7 CPUs. These sockets are physically incompatible with each other.
What is the height difference between the two Dynatron coolers?
The Dynatron B9 stands 2 inches tall, while the Dynatron Copper LGA1156 Blower Heatsink is only 1.12 inches high. The B9 is designed for 1U server chassis that allow for slightly more vertical space. The LGA1156 blower is ultra-compact to fit in small cases with tight clearance constraints. You must check your case height before choosing.
Which Dynatron heatsink is lighter?
The Dynatron Copper LGA1156 Blower Heatsink weighs 12.5 ounces. The Dynatron B9 is heavier at 1.04 pounds. The B9 includes a vapor chamber and double ball bearings, adding mass. The LGA1156 model is a simple blower design. If weight is a concern for your build, the LGA1156 unit is the lighter option.
Does the Dynatron B9 use a vapor chamber?
Yes, the Dynatron B9 utilizes a copper vapor chamber design. This helps distribute heat evenly across the base for the FCLGA3647 socket. The Dynatron Copper LGA1156 Blower Heatsink uses a solid copper base. Vapor chambers generally offer faster heat spreading than solid copper bases. This makes the B9 suitable for high-heat server applications.
What fan type do both Dynatron coolers use?
Both coolers feature fans with double ball bearings. This design is chosen for longevity and durability in active cooling applications. The Dynatron B9 is rated for server environments where continuous operation is required. The LGA1156 blower fan also uses this bearing type. Double ball bearings provide better stability and longer life than sleeve bearing fans.
Is the Dynatron B9 suitable for LGA1156 processors?
No, the Dynatron B9 is not suitable for LGA1156 processors. It is engineered exclusively for the FCLGA3647 socket. The mounting mechanism and base shape are specific to that server socket. You must use the Dynatron Copper LGA1156 Blower Heatsink for LGA1156 systems. Using the wrong cooler can damage your motherboard or CPU.
