Turemetal, a maker of cases for fanless PCs, has published photos of a passively cooled system featuring an AMD EPYC processor and an NVIDIA GeForce RTX 2070 graphics card. The computer uses numerous custom components, with the founder of TureMetal stating that this is a custom build for a specific customer, although it uses one of their standard fanless PC cases. 

The fanless system built by Turemetal is powered by AMD’s 32-core EPYC 7551 processor, listed as having a 180 W TDP, and GIGABYTE’s NVIDIA GeForce RTX 2070 video card with a 175 W TDP (355W total). These are both equipped into a Supermicro ATX motherboard, and then built inside a commercially available Turemetal UP10 chassis.

Officially the chassis supports a 140 W CPU and a 160 W GPU (300W total), but it looks like its actual capabilities are more impressive, and with a bit of tweaking it can house a rather extreme 32-core processor and a high-end graphics board.

At this time, according to Turemetal's YouTube channel, the system has passed FurMark's full-load test for CPU and GPU for 22 continuous hours without a crash or thermally throttling. In the video, we see a GPU temperature of 88C, and a CPU temperature of 76C, in a 24C ambient room.

Since the Turemetal UP10 was not designed for AMD’s EPYC processors, in order to meet the demands of the customer Turemetal had to build a custom copper heat spreader for the processor along with an appropriate mounting mechanism. The radiator weighs nearly 2.5 kilograms, so we are literally talking about heavy metal here. The test system currently uses an external PSU, but Turemetal says that eventually power supply will be moved inside the PC.

It remains to be seen when and whether the UP10 chassis with AMD EPYC 7551 support will be available commercially - if the custom block will be an 'add-on', or limited to specific customer requests. Meanwhile, good news is that some of Turemetal’s products are now available not only directly from Taobao, but also from Fully Silent PCs in the US and will soon be available in Europe shortly, reports FanlessTech.

    nice very impressive cooling but it is only ever going to be as good as the ambient background delta allows it wonder if they would consider a fanless water loop linked to the heat exchangers

    That's what I as thinking myself. A water loop with passive radiators. Like the old Innovatek passive radiators.

    Probably not. A lot of points of failure for not that much more gain. Heatpipes essentially act as "water cooling" in this case. All the water does in a normal loop is allow quick and easy transfer of the heat to the (larger) ratiators. The heatpipes to exactly that. The advantage of watercooling is flexibility (unless you like hard line tubing), where soft tubes can connect a ton of blocks to radiators, whereas heatpipes are harded to route through a system.

    Saw this guy's stuff before, didn't realize it's now named "Turemetal"...

    One of these would be amazing if they could supply a passively cooled version of the FSP Twins.

    Imagine a completely passive silent home server (just built one with an R7-2700 and 2x NVMe drives in RAID1 in a huge actively cooled tower case).

    On the other hand my server is pretty quiet but my UPS makes a racket, so maybe it won't improve anything.
