AMD Ryzen Threadripper 2990X Processor - Cooler Performance and Temperatures

For cooling, I used the Corsair H115i Pro AIO liquid cooler which is fully compatible with the Ryzen Threadripper processors and TR4 socket. These coolers come 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.

Following are the results of various Ryzen Threadripper CPUs in thermal benchmarking along with the VRM temps on each respective motherboard.

In general, the Ryzen Threadripper processors are based on the 12nm process from Glofo which offers slightly better temperatures and power efficiency numbers compared to Intel's 14nm based offerings. While Intel went with a solderless 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. You can check out the full delidding of Ryzen Threadripper processors by renowned overclocker Der8auer over here.
