For those seeking affordable gaming CPUs, platform longevity becomes even more important for future upgrades.

Cooling Requirements by CPU Tier

Budget CPUs (65W TDP) work fine with basic $25-35 tower coolers or even stock coolers when included.

Mid-range CPUs (105-125W TDP) need quality tower coolers ($40-60) or entry-level 240mm AIOs for optimal performance.

High-end CPUs (125W+ TDP) require premium air cooling ($70+) or 280mm/360mm liquid coolers to maintain boost clocks.

We measured 15°C temperature differences between adequate and premium cooling on high-end chips, directly impacting sustained performance.

The Intel Stability Situation

Intel’s 13th and 14th generation processors have experienced widespread degradation issues. Users report crashes, instability, and permanent damage after months of use.

Intel has released microcode updates that help, but damage to affected CPUs is permanent.

If buying Intel, stick to 12th generation or ensure any 13th/14th gen CPU has the latest BIOS with Intel’s default power limits enabled.
