SP5 vs LGA4677 Server Cooler Specs
Socket Compatibility
You must match the cooler to your processor socket. The TKJBHGPK 4U SP5 Server Cooler is built specifically for the SP5 socket. It targets AMD EPYC processors using this interface. In contrast, the TKJBHGPK 2U LGA4677 5 Heat Pipe Server Cooler supports the LGA4677 socket. This fits Intel Xeon Scalable processors from the 4th and 5th generations. These sockets are not interchangeable. You cannot install either cooler on a motherboard with the other socket type. Your choice depends entirely on whether your server uses an SP5 or LGA4677 platform.
Heat Pipe Count
Heat pipes transfer heat from the CPU to the fins. The TKJBHGPK 2U LGA4677 5 Heat Pipe Server Cooler includes five heat pipes. This design helps spread thermal energy efficiently across the heatsink. The data for the TKJBHGPK 4U SP5 Server Cooler does not list the number of heat pipes. We cannot confirm its internal construction. The 2U model provides a clear specification advantage here. You know exactly how many pipes are moving heat away from the chip in this unit.
TDP Rating
Thermal Design Power indicates how much heat a cooler can handle. The TKJBHGPK 2U LGA4677 5 Heat Pipe Server Cooler has a TDP rating of 400W. This suggests it is designed for high-power processors. The TKJBHGPK 4U SP5 Server Cooler data does not provide a TDP rating. You do not know its maximum heat dissipation capacity from the specs. The 2U model offers a concrete limit for your planning. The 4U model leaves this critical performance metric undefined in the provided information.
Fan Speed
Fan speed affects airflow and noise levels. The TKJBHGPK 4U SP5 Server Cooler features fans running at 3800 RPM. This is a high rotational speed for server cooling. The data for the TKJBHGPK 2U LGA4677 5 Heat Pipe Server Cooler mentions high-speed PWM fans but does not list a specific RPM. You can compare the 3800 RPM figure directly for the 4U model. The 2U model lacks a specific speed number in the specs. The 4U model wins this round by providing a precise fan speed value.
System Height
Server chassis height limits the cooler size. The TKJBHGPK 4U SP5 Server Cooler is a 4U unit. It requires a server chassis with 4U of vertical space. The TKJBHGPK 2U LGA4677 5 Heat Pipe Server Cooler is a 2U unit. It fits into chassis with 2U of vertical space. These are different form factors. You need to check your server rack or tower dimensions. The 2U model allows for lower profile installations. The 4U model requires more vertical clearance. Your chassis determines which height works for your build.
Choose Your Server Cooler
You have an AMD EPYC SP5 processor
You must choose the 4U SP5 Server Cooler because it is built for the SP5 socket. It features a fan speed of 3800 RPM. This matches your AMD EPYC hardware perfectly. The 2U LGA4677 model is not compatible with your socket. Pick this unit to ensure proper fit and cooling for your server environment.
You use an Intel LGA4677 4th or 5th Gen CPU
Select the 2U LGA4677 cooler for your Intel processors. It supports the LGA4677 socket for 4th and 5th generation CPUs. It includes five heat pipes for efficient heat transfer. The TDP rating is 400W. It also supports PWM fans for speed control. This unit is the correct choice for your specific motherboard socket.
You need high TDP cooling for dense servers
The 2U LGA4677 model handles up to 400W TDP. It uses five heat pipes to move heat away from the CPU. The PWM fan allows you to adjust speed based on load. This design suits high-performance servers with significant thermal output. The 4U SP5 option does not list a TDP rating or heat pipe count.
