Ryzen 9 7950X Passively Cooled with 2.2lb Copper Bar
Who does not love fanless computer systems? Nonetheless, generally aftermarket choices might not meet your wants. that is what occurred to somebody Reddit user (opens in new tab). As a substitute of utilizing an aftermarket passive CPU cooler, the veteran fanatic modified 1kg copper bars to chill the Ryzen 9 7950X, top-of-the-line CPUs in the marketplace.
The consumer’s system revolves across the Streacom DB4, a fanless chassis that caters to mini-ITX builds. Inside, an MSI MPG B650I Edge WiFi homes AMD’s 16-core Ryzen 9 7950X and 64GB of DDR5 reminiscence; in the meantime, an HDPLEX 250W GaN ATX energy provide offers as much as 250W of energy.
The DB4 comes with a passive heatsink that helps chips as much as 65W. Streacome additionally provides an elective module that will increase the cooling capability to 105W. Nonetheless, it nonetheless lags behind the 170W TDP of the Ryzen 9 7950X, so the avid DIYer has taken issues into his personal arms. Plus, the consumer tends in the direction of fanless methods.
The core of the user-replaced cooling system is 2 ESG Feinkupfer 1 kg (2.2 lbs) copper rods, which retail for round US$100 every. The Redditor reused the small plate that got here with the Streacom DB4 however added a specifically designed 233mm (9.17in) copper bar to maintain the CPU and motherboard chipset cool. Unmodified copper bars switch warmth to the 4 aspect panels of the Streacom DB4. In line with their estimates, the system is at present round 13 kg (28.66 lbs), the copper mixture is 4.4 kg (9.7 lbs), and the case and different components are 7.5 kg (16.53 lbs) and 1 kg (2.2 lbs). lbs) is checked. , respectively.
He didn’t use solder to attach the totally different copper components and the copper bar to the panels of the case. As a substitute, the Redditor used Thermal Grizzly Conductonaut, a liquid metal-based thermal compound between the copper components, and Arctic MX-6, a carbon-fill-based thermal compound the place the copper bar contacts the case panel.
After pushing the Ryzen 9 7950X to the max for 2 hours, the proprietor noticed 95 levels Celsius on the CCD1 and 90 levels Celsius on the CCD2. The Streacom DB4’s aspect panel temperatures fluctuated between 50 and 60 levels Celsius, whereas the motherboard temperature was round 77 levels Celsius. Temperatures aren’t unhealthy. Soldering the joints will assist enhance temperatures. After all, the cooling efficiency of a copper rod can’t be in comparison with that of a warmth pipe or a steam chamber. Fanatics use their system for programming in order that the processor doesn’t run in its most state for prolonged durations of time. Subsequently, a do-it-yourself copper heatsink ought to correspond to the wants of its proprietor.
