Noctua has announced three new heatsinks for AMD’s new high-end CPU platforms, Threadripper and EPYC. If you’ve been following the company, or Morry’s motherboard reviews, then you know that these coolers are huge (and effective).
Apparently the main difference is the contact surface, 70mm x 56mm, to accommodate for the processor’s large package. AMD connects multiple dies together with their Infinity Fabric, which means a huge total surface area. The cooler comes in three sizes, corresponding to the fan that’s intended to be used with it: 140mm (NH-U14S TR4-SP3), 120mm (NH-U12S TR4-SP3), and 92mm (NH-U9S TR4-SP3).
The two “smallest” sizes, NH-U12S and NH-U9S, are both expected to retail for $69.90 USD, so I guess choose whichever makes the most sense for your system. The largest one, the NH-U14S, is $10 more expensive at $79.90 USD. They should be available by the end of the month.
