FAQ
Is air cooling enough for the 5995WX?
Air cooling is sufficient for stock operation, but liquid cooling is recommended to prevent thermal throttling during extended, high-load professional rendering or simulation tasks
Does radiator size impact 5995WX performance?
Yes, a larger radiator provides greater thermal mass and surface area, allowing the 5995WX to maintain higher boost clocks for longer durations under heavy load
Why is mounting pressure critical for this CPU?
The 5995WX features a massive heat spreader; uneven mounting pressure leads to localized hotspots, causing premature thermal throttling and reduced overall system performance
