M.2 PCIe Performance

The WD SN730 SSD is certainly not the fastest SSD on today’s market and is not even PCIe Gen 4. It does, however, prove solid enough for OS duties. And cooling from the Lenovo heatsink is not a concern with our tested peaks staying well below 50C.

System Temperatures

Check out the main video on YouTube or Vimeo for a closer look at power, thermals, clocks, and noise performance.

In terms of system temperatures, the CPU was just shy of 90C after 30 minutes of heavy load while the GPU chugged away at 75C (90C hotspot) at the same time. The recorded noise output for simultaneous CPU and GPU loading was around 48-50dBA. This does not tell the whole story, though, as there was a consistent rumbling noise from the fans or chassis which was highly irritating to my ears. Watch the video review for a closer look.

Power draw from the system was in the order of 380W at the wall with just the CPU loaded. This climbed up to around 580W from the wall with both the CPU and GPU heavily loaded. There is clearly ample headroom from the 1kW PSU even if you want to add a second graphics card.
