Noctua NH-D12L Dual Tower CPU Cooler - 120mm-Class Cooling For 4U Server Cases

Noctua NH-D12L Dual Tower CPU Cooler - 120mm-Class Cooling For 4U Server Cases: With the dozens of 4U rackmount enclosures used at Phoronix, when it comes to the high-end desktop systems the Noctua NH-U9 series has been the go-to choice for CPU cooling. The Noctua NH-U9 series has been capable of cooling HEDT systems even with Threadripper / EPYC processors using the NH-U9 TR4-SP3 while fitting within 4U height requirements. For the Noctua NH-U9 series and other 4U compatible heatsinks they've tended to be limited to 80~92mm cooling fans due to height requirements. Noctua though recently introduced the NH-D12L as offering a dual tower CPU heatsink design capable of fitting 120mm fans and has been the focus of our recent testing.
