The GeForce RTX 3080 tried to cool passively. It turned out to be expensive and ineffective
The Chinese company Turemetal, specializing in creating cases for fanless PCs, conducted an experiment with passive cooling of the GeForce RTX 3080 graphics accelerator. Ampere’s hot temper was too tough for the flagship Turemetal UP10 case, which costs almost 800 dollars.
Tested with an AMD Ryzen 5 5600X 6-core processor with a stated rated power consumption of 95W. The Turemetal UP10 body itself is made of aluminum. Its side walls are ribbed and function as large radiators, to which heat from hot system components is distributed through twenty 8 mm nickel-plated copper heat pipes capable of dissipating up to 250 watts of heat.
The case was tested in a very unnatural environment for a typical residential environment. At the time of the experiment, the ambient temperature was only 13.6 degrees Celsius, with an air humidity of 64%. To test the Turemetal UP10 passive cooling system’s effectiveness, a Furmark stress test was used, during which the CPU was subjected to minimal stress.
The beginning of the experiment was very successful. The sensors showed that the unreferenced ASUS GeForce RTX 3080 TUF’s GPU temperature was only 18 degrees Celsius. However, after a few seconds from the start of Furmark, the graphics chip warmed up to 87 degrees. It should be noted that the test itself displayed this temperature. It did not take into account the indicator of the hottest point of the crystal.
During testing, the system peaked at about 410 watts.
