Who does not like fanless PCs? However generally, aftermarket choices might not meet your necessities. That was what occurred to 1 Redditor (opens in new tab). As a substitute of utilizing an aftermarket passive CPU cooler, the ingenious fanatic modded some 1kg copper bars to chill his Ryzen 9 7950X, one of many finest CPUs available on the market.
The consumer’s system revolves across the Streacom DB4, a fanless case that caters to mini-ITX builds. Within the 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 supplies as much as 250W of energy.
The DB4 comes with a passive cooler that helps chips as much as 65W. Streacome additionally presents an non-obligatory module that expands the cooling capability to 105W. Nevertheless, it nonetheless falls in need of the Ryzen 9 7950X’s 170W TDP, which is why the avid DIYer took issues into his personal palms. Plus, the consumer has an affinity for fanless methods.
The core of the user-modified cooling system is the 2 ESG Feinkupfer 1kg copper bars, which retail for about $100 apiece. The Redditor reused the small plate that comes with the Streacom DB4 however added a custom-tailored 233mm copper bar to maintain the processor and the motherboard’s chipset cool. The unmodified copper bars switch the warmth towards the Streacom DB4’s 4 aspect panels. Based on his estimates, the system now weighs round 13kg, with the copper combining for 4.4kg and the case and different components checking in at 7.5kb and 1kg, respectively.
He did not use soldering to attach the totally different copper components and the copper bar to the case’s panels. As a substitute, the Redditor utilized Thermal Grizzly Conductonaut, a liquid metal-based thermal compound, between the copper components, and Arctic MX-6, a carbon filler-based thermal compound, the place the copper bar makes contact with the case panel.
After pushing the Ryzen 9 7950X to the max for 2 hours, the proprietor noticed 95 levels Celsius on CCD1 and 90 levels Celsius on CCD2. The motherboard temperature was about 77 levels Celsius, whereas the Streacom DB4’s aspect panel temperatures oscillated between 50 and 60 levels Celsius. The temperatures should not unhealthy. Soldering the joints would assist with enhancing the temperatures. After all, the cooling efficiency from a copper bar does not evaluate to that of a warmth pipe or a vapor chamber. The fanatic makes use of his system for programming so the processor does not run at its most state for extended durations. Subsequently, the DIY copper cooler ought to go well with the proprietor’s wants.
