Reddit is a network that also contains its share of weirdness, the proof with a large AMD Ryzen 9 7950X processor passively cooled. For this, the user used no less than 2 kg of copper. So failure or success?
A passively cooled Ryzen 9 7950X in a modified Streacom case!
The user in question opted for a case from Streacom, a DB4. However, it is a model that, as standard, is adapted for CPUs with a TDP of 105W maximum via the addition of specific modules. Clearly insufficient for the 170W TDP of a 7950X.
Therefore he had to modify the installation and the standard cooling system. For the occasion, he used two copper bars of 1kg each. Finally, a last plate of 223g was used to make the connection between CPU, chipset and case. Nevertheless, in order to “join” the different elements, no soldering was done. Instead, liquid metal is at work to facilitate heat transfer between the copper parts. As for the copper/casing junctions, classic thermal paste is used, remembering that the case is made of aluminum.
Concretely, this translates into high temperatures with a CCD1 reaching 95°C against 90°C on the second one when the CPU is used at 100%. Otherwise, the panels of the case run between 50°C and 60°C, of course, we will not put our fingers on them under penalty of nasty burns.
Finally, the rest of the configuration uses an MSI MPG B650i Edge WiFi motherboard and 64 GB of DDR5 memory. Concerning the power supply, a 250W HDPLEX GaN ATX block is used.
