A fantastic CPU built to support multi-core workloads and complex tasks, AMD’s Ryzen 9 3950X can be an exceedingly high performer. With 16 cores and 32 threads to speak of, the desktop processor can reach dizzying Boost speeds of up to 4.7GHz. But getting the best out of the chip can generate of a lot of heat, especially when it’s utilised within a small form factor. Although its TDP doesn’t first appear astronomical, officially rated at a reasonable 105W, harnessing this within a 1U rack mount unit while using boost frequencies can draw up to 200W. Even with the recent introduction of the cooling-conscious X570 motherboard, there is still work to be done to help regulate the processor’s temperature. Our latest development project not only makes this possible, but helps our customers achieve the best possible performance from the impressive CPU too.
The cooling conundrum
Typically within a 1U rack mount computer, air will simply flow through the unit and be expelled without fulfilling any other purpose. But there is a lot of potential for this air flow to be harnessed as a method of passive cooling, something which is generally overlooked by PC manufacturers. Likewise, the fan on most AMD-based motherboards’ heatsink locks are not sufficient to cool the chip while trying to achieve the best clock speed possible. That leaves us with the option of a water-cooling solution, which while achievable, isn’t necessarily viable within the compact size of a rack mountable 1U unit.
We have the solution
Following rigorous research and development, we’ve achieved a design using rapid prototyping techniques that enables our customers to gain better performance from the 3950X while keeping the chip cool within our 1U Plus. By creating bespoke ducting that harnesses the air from the unit’s fans, we’ve made it possible to port this air flow over where the CPU sits in order to cool this passively and effectively. This sees the processor is able to consistently run at its Boost speed while only achieving a maximum temperature of 90 degrees. That way, you can get the very best out of the Ryzen chip without having to worry about things heating up.
Keeping things cool
This unique cooling solution will become available within our 1U Plus very soon. Until then, if you would like to learn more about how you can effectively cool AMD’s Ryzen 9 and Threadripper chips within our range of rack mount PCs, please get in touch.
