Cooling tips
Enable AMD Precision Boost Overdrive in BIOS for optimized thermal-to-performance scaling.
Apply a small pea-sized amount of thermal paste to ensure even heat spreader coverage.
Set a custom fan curve in BIOS to minimize noise during light tasks.
Installation
Ensure AM4 socket compatibility and check RAM clearance, though these compact coolers rarely interfere with memory modules
FAQ
Is the stock AMD Wraith Stealth cooler enough?
Yes, it handles basic tasks, but an inexpensive tower cooler runs much quieter and keeps boost clocks sustained longer
