THERMAL BENCHMARKS

We use Cinebench R23 multicore (stability test), for CPU thermal testing. This provides worse case scenario for given CPUs thermal output.

CONCLUSIONS

Noctua NH-L12S has good build quality and is straightforward to mount. It has quiet operation, even at full load. The NF-A12x15 fan reached maximum of 35dB at 100% load; recorded from distance of 50cm in our testing.
