New Challenger: Sudokoo Mach 120 Takes on Noctua’s Best

Video Description

Today we’re taking a look at the Sudokoo Mach 120, a new fan aiming to challenge the Phanteks D30 and Noctua A12x25 G2, two of the top 120mm models on the market. We’ll be testing airflow, noise, and thermal performance inside a controlled case setup to see how those claims hold up in real-world conditions. So, is the Mach 120 a genuine contender or just another marketing claim? Let’s find out.

All tests were conducted with a manual CPU overclock, locking the all-core frequency and VCORE to ensure consistent load across runs. Baseline Measurement: • Ambient temperature was recorded. • The system was left idle for 10 minutes. • CPU and GPU temperatures were logged using HWINFO, while case temperatures were monitored with thermocouples placed at three positions:
