PCSpecialist Topaz Spark Review (Ryzen 5 7500F/RX 6700)

In terms of CPU thermals, the compact PCS FrostFlow air cooler had zero issues dealing with the Ryzen 5 7500F. During an all-core Cinebench workload, the CPU drew 90W package power but was kept to just 80C, and it ran even cooler while gaming, peaking at 73C during a 30-minute stress test in Cyberpunk 2077.

The GPU is also nothing to worry about. The hot spot is slightly higher than I'd like at 98C, though AMD is very clear this can safely go up to 110C. You could set a custom fan curve however if you want to see lower temperatures, as the Sapphire Pulse does favour low-noise, running the fans at just 1000rpm or so.

That ties in nicely with overall noise levels, as the Topaz Spark is a pretty quiet gaming PC. With our sound meter just 30cm from the system, it produced just 38dBa of noise while running Cyberpunk 2077, so it was really not intrusive at all and would easily be blocked out by a headset.

Finally, taking a look at total system power draw, in our gaming tests we saw power draw hit around 320W at 1440p. That is well below the 750W capacity of the Corsair unit but goes to show how much headroom there is for upgrades – you could easily upgrade to a higher power CPU and GPU without causing the PSU to break sweat, which is great for system longevity.
