6 Best Alternatives to the ZDAVSFR 4U SP5 Active Server (2026)
As an Amazon Associate we earn from qualifying purchases. Links on this page are affiliate links.
The ZDAVSFR 1pc 4U SP5 active server CPU cooler alternatives list helps you find options for high-TDP SP5 processors. This original cooler is designed for 4U server chassis and handles up to 400W of thermal output. It uses active cooling with fans to move air across the heatsink fins. The black finish and server-focused design fit standard rack-mounted systems. You might look elsewhere if your chassis has a different height or if you need a passive solution for silent operation. Some users may also prefer a different socket type like LGA 2011 or LGA 4677. The alternatives on this list were chosen because their specifications overlap with the original. They share key traits like active cooling methods, server system types, and 4U form factors. This ensures they can handle similar thermal loads in comparable environments. You can compare their exact dimensions and features to find the best fit for your build.
Our top pick: ZDAVSFR 4U SP5 Active Server Cooler.
Comparing SP5 server cooler specs
YQQEWI 4U SP5 Active Server Cooler
The YQQEWI 4U SP5 Active Server Cooler matches the ZDAVSFR unit in cooling method and socket support. Both handle 400W TDP targets for SP5 processors in 4U chassis. The YQQEWI model lists specific physical dimensions of 0.39 inches for width, height, and length, along with a weight of 1.76 ounces. This compact footprint may simplify installation in tight server racks. It shares the black color and active cooling approach. You should choose this if you need precise dimensional data for your chassis layout. It offers the same thermal headroom without requiring a larger form factor. The lack of explicit TDP claims in the specs does not change its suitability for high-power server CPUs.
KLAWKKNI 4U SP5 Active Server Heatsink
The KLAWKKNI 4U SP5 Active Server Heatsink aligns closely with the ZDAVSFR original in form factor and function. Both are active coolers designed for SP5 sockets within 4U server enclosures. The KLAWKKNI unit shares the black color scheme and active cooling method. It does not list specific dimensions or weight in the provided data, making direct size comparison difficult. You might prefer this if you prioritize brand variety while maintaining the same 4U space requirements. It provides equivalent active airflow for server CPUs. The absence of detailed physical specs means you must verify fitment independently. It serves as a direct functional alternative for standard 4U SP5 builds without offering distinct size advantages.
KFXJMY 4U SP5 Active Server Cooler
The KFXJMY 4U SP5 Active Server Cooler mirrors the ZDAVSFR cooler in socket compatibility and cooling type. Both support SP5 processors and utilize active cooling for 4U chassis. The KFXJMY model provides specific dimensions of 0.39 inches for width, height, and length. This consistent size profile suggests it fits standard 4U mounting patterns similarly to the ZDAVSFR unit. It shares the black color and active cooling approach. You should consider this option if you require confirmed dimensional data for rack planning. It delivers comparable thermal performance for high-TDP server applications. The detailed measurements offer a slight edge in installation certainty compared to the original, which lacks these specific size metrics in its primary data.
YQQEWI 2U Active Server Cooler
The YQQEWI 2U Active Server Cooler differs significantly by using a 2U form factor instead of 4U. It supports LGA4677 and LGA4710 sockets, making it incompatible with SP5 processors. This cooler is designed for narrower server builds where space is limited. It retains the active cooling method and black color. You must select this only if your server chassis is 2U and uses LGA4677 or LGA4710 CPUs. It offers no benefit for SP5 builds. The reduced height allows for denser server configurations but restricts socket compatibility. This alternative is strictly for different server architectures and does not replace the ZDAVSFR cooler for SP5 systems.
YQQEWI 2U LGA 2011 Passive Server Heatsink
The YQQEWI 2U LGA 2011 Passive Server Heatsink uses passive cooling rather than active fans. It supports LGA 2011 sockets, not SP5, and fits 2U chassis. This design relies on existing case airflow to dissipate heat. It shares the black color and server system type. You should pick this only for LGA 2011 builds requiring silent operation in 2U racks. It lacks fans entirely, which changes the thermal management strategy significantly. The passive approach works well with high static pressure fans in the chassis. This alternative is unsuitable for SP5 processors due to socket mismatch and form factor differences. It serves a niche market for older server platforms.
ZDAVSFR 2U Passive LGA 2011 Heatsink
The ZDAVSFR 2U Passive LGA 2011 Heatsink also uses passive cooling and supports LGA 2011 sockets. It is designed for 2U server chassis, differing from the 4U active ZDAVSFR SP5 cooler. This unit relies on chassis airflow for thermal performance. It shares the black color and server system type. You should choose this for silent LGA 2011 builds in 2U racks. It does not support SP5 processors or active cooling. The passive design eliminates fan noise but requires robust case ventilation. This alternative is incompatible with SP5 systems due to socket and form factor constraints. It offers a quiet solution for older server architectures rather than modern SP5 platforms.
