AMD Ryzen X399 Motherboards Revisited – The ASRock X399M Taichi and ASUS X399-E ROG STRIX Review
AMD Ryzen Threadripper 1920X and 1900X CPU - Cooler Performance and Temperatures
For cooling, we used the Noctua NH-U14S TR4/SP3 cooler which is fully compatible with the Ryzen Threadripper processors and TR4 socket. This version comes with a larger surface area that makes full contact with the huge IHS on the Threadripper chips. This huge contact allows for better heat transfer to help cool the processor effectively.
In general, the Ryzen Threadripper processors are based on the 14nm process from Glofo which offers slightly better temperatures and power efficiency numbers compared to Intel’s 14nm based offerings. While Intel went with a solder less design, the Ryzen Threadripper chips come with liquid metal thermal paste on each of the four dies that are featured on the chip interposer.
This refined thermal interface offers much better heat transfer than Intel’s TIM and the Indium based solder design means that all air gaps are removed and the chip itself is tightly packaged so that the IHS can fully unload the heat from the dies and pass it straight to the cooler itself. Furthermore, the dies feature gold plating on the back to ensure proper thermal cycling which adds to the thermal qualities of this impressive chip.
