- The author's computer PSU fan became excessively loud, measuring 63 dB, making it uncomfortable to use without headphones.
- Identifying the Cooler Master V750 SFX PSU as the source, the author explored warranty options but found them impractical due to long repair times and the need for a temporary replacement.
- Research revealed risks of DIY PSU repairs due to high voltage dangers, but also successful fan replacement stories using adapters or crimping connectors.
- The author opted to replace the noisy fan with a Noctua NF-A9x14, using solder seal connectors for a secure and compact solution.
- After installation, the new fan reduced noise to 43 dB, a significant improvement, despite potential differences in fan performance and lifespan implications.
