Cooling and hardware guidance for stress testing: CPU coolers, thermal paste, case airflow, temperatures, undervolting and memory choices.
PSU Sizing for Overclocking: Headroom, 80 Plus and Shutdown Clues Key points first: A stress test exposes a marginal power supply in a way ordinary use rarely does, because Prime95 holds the processor at maximum sustained draw while the rest of the system is also awake. Instant shutdowns or restarts under load, with no error…
Best DDR5 for Stability Testing: How to Choose Memory That Holds Up Key points first: For stability testing, the right DDR5 kit is the one your processor’s memory controller can drive without complaint, not the one with the most aggressive numbers on the box. Higher rated speeds and tighter timings increase the controller’s burden, four…
Undervolting Guide: Lower Heat Without Losing Stability Key points first: Undervolting means asking the processor to run at its usual clock speed while supplied with less voltage, which lowers power draw and heat roughly in step. The catch is that every individual processor tolerates a different amount, and an undervolt that is slightly too aggressive…
Case Airflow for Stress Tests: Keep Prime95 Runs From Heat-Soaking Key points first: A CPU cooler can only hand heat to the air inside the case; case fans must then carry that air out and replace it with cooler room air. Long Prime95 runs expose weak case airflow because the air inside slowly warms until…
Prime95 Temperatures Explained: What the Numbers Actually Mean Key points first: Prime95’s own documentation gives no universal safe temperature, and this page will not invent one. The limit that matters is the one the maker of your exact CPU model publishes, commonly labelled TjMax or maximum operating temperature. Small FFTs runs hottest because it is…
Thermal Paste Guide: When to Replace It and How to Apply It Key points first: Thermal paste fills the microscopic air gaps between your processor’s heat spreader and the cooler base, and air is a poor heat conductor. Paste dries and pumps out over years of heat cycles, so old paste is a common, cheap…
Best CPU Coolers for Stress Testing: Air Cooling That Survives Prime95 Key points first: Prime95 Small FFTs is the Torture Test preset the program itself describes as producing maximum power, heat and CPU stress, so it is the honest yardstick for cooler shopping. Judge a cooler by fit first (case clearance and memory height), then…
