Dynatron J12 — 3U Active CPU Cooler forAMD Socket SP5
3U Active CoolerSocket SP5 (EPYC Genoa)Copper + Heat-Pipe Heatsink80mm PWM Fan

Typically in stock with fast delivery across Cyprus.
Compatibility — check before buying:
Designed forAMD Socket SP5 (EPYC Genoa) in 3U and taller server chassis. Its 105mm height requires adequate clearance and it does not fit desktop LGA or AM sockets. Confirm your chassis height and SP5 mounting before ordering.
Best For
✓3U (and taller)AMD EPYC Genoa servers on Socket SP5
✓High-TDP server processors needing active cooling
✓Data-centre and HPC node thermal management
✓Replacement or spare active cooler for SP5 systems
✓Builds where chassis fans alone are insufficient
✓Copper heat-spreader cooling for sustained loads
Key Features
3U Active Server Cooling
A tall 3U heatsink with a dedicated 80mm fan delivers focused active airflow over the CPU, suited to dense EPYC servers where a low-profile or passive cooler cannot keep up.
Copper-Embedded Heat-Pipe Heatsink
Aluminium fins combined with heat pipes and an embedded copper heat spreader move heat away from the SP5 die quickly for stable temperatures under sustained load.
High-Speed 80mm PWM Fan
The 80 x 80 x 38mm double-ball-bearing fan scales from 2400 to 8000 RPM under PWM, pushing up to 115.61 CFM when needed, with a 70,000-hour MTBF for always-on operation.
Built for High-TDP EPYC
Rated for demanding SP5 processors (up to 580W maximum at 20 degrees C ambient), the J12 provides the thermal capacity high-core-count EPYC Genoa CPUs require.

Frequently Asked Questions
Which processors does the Dynatron J12 support?
It is built forAMD EPYC Genoa processors on Socket SP5 in 3U and taller server chassis. It is not compatible with desktop AM5 / AM4 or Intel LGA sockets.
Is it an active or passive cooler?
It is an active cooler with a dedicated 80mm PWM fan rated up to 8000 RPM, providing forced airflow rather than relying on chassis fans, which is essential for high-TDP EPYC CPUs.
What TDP can it handle?
Dynatron rates it for high-TDP SP5 processors, up to 580W maximum at 20 degrees C ambient, giving ample capacity for high-core-count EPYC Genoa chips.
Will it fit my server?
The cooler stands 105mm tall (118 x 92.4 x 105mm), so it needs a 3U or taller chassis with sufficient clearance. Check your chassis height and SP5 mounting before ordering.
Singular Expert Insight
The J12 is a purpose-built OEM-grade cooler forAMD EPYC Genoa SP5 servers, not a desktop part. For 3U EPYC nodes running high-wattage CPUs, its heat-pipe copper heatsink and high-RPM fan deliver cooling headroom that chassis airflow alone cannot; for desktop or lower-profile builds, choose an appropriate model. Explore our full CPU Coolers range, and complete server and workstation upgrades with reliable units from our PC Power Supplies selection.
Buyer's Guide
Buy it if
You are building or servicing a 3U or tallerAMD EPYC Genoa server on Socket SP5 and need an active cooler with a heat-pipe copper heatsink rated for high-TDP CPUs.
Skip it if
You have a desktop PC, a non-SP5 socket, or a chassis under 3U — this tall server cooler will not fit standard cases or AM5 / AM4 / Intel LGA sockets.
Also consider
A lower-profile SP5 cooler for 1U/2U chassis, or a desktop AIO or air cooler for non-serverAMD or Intel builds.
