Air cooling
Noctua NH-U14S TR5-SP6
This Threadripper-specific cooler offers the best all-around air cooling for high-TDP workstations
Why it fits: Surprisingly listed, this air cooler is a bare minimum for light loads
- Direct TR5/SP6 socket compatibility
- Reliable Noctua build quality
- No pump noise or failure points
- Limited cooling capacity for extreme loads
- Large physical size, potential clearance issues
Cooling class ~385W
Radiator —
Noctua NH-D9 TR5-SP6
A compact Threadripper air cooler, offering a smaller footprint and more affordable option
Why it fits: A compact air cooler, likely insufficient for this CPU's demands
- Direct TR5/SP6 socket compatibility
- Compact size for better case compatibility
- No pump noise or failure points
- Insufficient for heavy, sustained workloads
- Will likely run loud under any significant load
Cooling class ~385W
Radiator —
Noctua NH-D15 chromax.black
The NH-D15 is a highly regarded air cooler, but this specific model lacks direct TR5/SP6 mounting. Even with an adapter, its cooling capacity, while excellent for mainstream CPUs, will be pushed to its absolute limits by this Threadripper PRO
Why it fits: A strong air cooler, but still challenged by extreme Threadripper PRO loads
- Exceptional air cooling performance
- Quiet operation at moderate loads
- Renowned Noctua reliability and support
- Lacks native TR5/SP6 mounting
- Challenged by extreme Threadripper loads
Cooling class ~250W

Ensure good case airflow with multiple fans.
Installation
Verify TR5/SP6 socket compatibility and check case clearance for large air coolers or AIO radiators
FAQ
Is air cooling ever sufficient for this CPU?
For light to moderate use, some specialized air coolers can cope, but heavy, sustained loads absolutely require liquid cooling
What radiator size is truly recommended?
A 360mm or 420mm AIO is strongly recommended. The larger, the better, for optimal thermal management
Should I consider custom liquid cooling?
For peak performance and aesthetics, custom loops offer the best thermal control and quiet operation for this chip
