7 Mistakes Even Veteran PC Builders Still Make

5. Ignoring Thermal Management

Thermal management is often treated as a set-it-and-forget-it part of the build process—especially by seasoned builders who’ve seen their cooling setups perform reliably in the past. But with each new generation of CPUs and GPUs, thermal output climbs, and yesterday’s cooling solution may no longer cut it. What worked for a mid-tier build a few years ago might buckle under the heat of today’s high-core-count processors and power-hungry graphics cards.
