Chicken 64 returns with a detailed look at reducing noise from the Commodore 128D fan. This system, with its integrated PSU, relies on a small 60 mm unit that many users find distractingly loud. The video explores whether replacing it can deliver a quieter experience without harming performance.
The original fan produced strong airflow, measuring around 5 m/s, but the noise level was overwhelming. To address this, Chicken 64 tested a modern Noctua NF6X25 fan. Although the new fan generated less airflow at about 2.5 m/s, it promised a far quieter operation.
Testing went beyond simple comparisons. The experiment included airflow checks, temperature monitoring with a probe over five hours, and direct noise measurements from both the front and back of the case. Results showed that while the new fan allowed the PSU to run about three degrees warmer, the noise difference was significant. The Commodore 128D fan swap reduced sound levels to a far more comfortable range.
The final verdict was positive. The Noctua fan proved adequate for cooling under normal conditions, especially in cooler environments. The slight tradeoff in airflow was outweighed by the dramatic drop in noise. Chicken 64 confirmed that the Commodore 128D fan replacement is a worthwhile upgrade for users who value quiet computing.
The video captures every step of the process, from opening the case to final testing. It offers a clear comparison for anyone considering the change. Retro hardware enthusiasts who own this model will find the demonstration helpful, especially if the stock fan noise has been frustrating.
