What modification was made to the AMD Threadripper Pro 9995WX CPU?

The integrated heat spreader (IHS) of the CPU was machined into a custom waterblock with integrated coolant channels.

What were the performance results of the extreme cooling setup?

The CPU maintained an overclock of 5.325GHz on all 96 cores, achieving high benchmark scores and peaking at 52 degrees Celsius despite drawing over 1,300W.

How much power did the overclocked Threadripper CPU consume?

At its peak, the Threadripper CPU consumed over 1,300W, with the entire system drawing over 1,700W.

A groundbreaking modification has been applied to a 96-core AMD Threadripper Pro 9995WX CPU, transforming its integrated heat spreader (IHS) into a functional waterblock. This intricate modification, inspired by micro-fluidic cooling concepts, was executed by the channel Geekerwan, aiming to tackle the immense heat generated by high-end workstation processors.

The custom waterblock features precisely machined coolant channels designed to directly cool the chiplets, maximizing thermal transfer. This setup was then connected to a substantial 140-liter external reservoir and an industrial chiller capable of 800W cooling power. Powerful Bosch pumps, repurposed from a Mercedes vehicle, ensured adequate coolant circulation.

These cooling efforts yielded extraordinary results. The modified Threadripper was sustained at an overclock of 5.325GHz across all 96 cores. This allowed for record-breaking benchmark scores, including 205,000 points in Cinebench R23. During peak performance, the CPU alone consumed over 1,300W, with the entire system drawing more than 1,700W, yet temperatures remained controlled at a maximum of 52 degrees Celsius.
