Reddit member Prestigious_Gate_615 created a passively cooled PC Ryzen 7 7700X, RTX 4060 with 2 massive radiators without fans. The design uses NH-P1 radiators from Noctua as the main passive cooling component. However, he used 3D printed brackets to mount the entire system to provide optimal contact area with the CPU and GPU and hold the assembly together.
The build uses an AMD Ryzen 7 7700X processor, as well as an NVIDIA GeForce RTX 4060, which suggests that passive cooling can support modern components. Despite using the lowest TDP GPU in NVIDIA’s Ada Lovelace line, the enthusiast adjusted the TDP to 90W from the usual 115W to reach temperatures 80-85 ° C at 100% load.
The Ryzen 7 7700X has also been put into “Eco Mode”, meaning its TDP has been reduced to 88W and its temperature limit has been set to 95 ° C. Reducing the power limits here was necessary because despite the Noctua’s larger heatsink, they can’t properly cool the components.
The assembly was constructed using the following components:
- Processor: Ryzen 7 7700X.
- Video card: RTX 4060, Gigabyte Windforce OC.
- Motherboard: MSI B650I Edge WiFi.
- RAM: 2×32 GB G.Skill Flare X5 6000 CL30.
- SSD: Lexar NM790 with a capacity of 4 TB.
- Power supply: Seasonic Prime fanless 500W PX.
- Райзер: Streamcom RZ4.
- Heatsinks: 2x Noctua NH-P1.
This is a pretty interesting idea, but it has limitations, mainly related to power consumption and temperature, since passive cooling is definitely not a good idea unless you use low-power components.
For example, for passive cooling, you can put all the premium components in the Streacom SG10 case, which can dissipate 600 W of power without fans.
