Modern CPUs routinely exceed their advertised TDP thanks to boost technologies like Intel Turbo Boost and AMD Precision Boost, plus motherboard vendors that ship with relaxed power limits. A 125W TDP chip can easily draw 180–220W under all-core workloads. Undersizing your cooler doesn't just raise temperatures — it directly throttles boost clocks and costs real performance. The right approach is to treat TDP as the floor for cooler capability, then consult real-world reviews to understand actual sustained power draw before choosing a cooling solution. ## Full article daily.dev links to this article rather than hosting it.
