CPU cooling, temperatures, fans and thermal paste explained.

This CPU temperature guide answers the question every PC owner asks: what is too hot for a CPU, and what should you do about it? The short answer is that under 85°C under full load is fine, 85–95°C is hot…
The best thermal paste for CPUs in 2026 is the one that is easy to apply, lasts for years and costs a few dollars — because the difference between the best paste and a decent one is only a couple…

To improve PC airflow for a cooler CPU, give the hot air a clear path out of the case — and the cheapest way to do that is to get the fan direction right, clean the dust out, and stop…
Choosing an air cooler vs liquid cooler comes down to your chip, your case and your budget — and the honest answer is that a good air cooler wins for most people, while a liquid cooler wins for the hottest…

Learning how to monitor CPU temperature is the simplest way to know whether your PC is healthy — a quick check tells you if the chip is cool, warm or overheating, and whether your cooler is doing its job. It…
If you are asking why is my CPU overheating, start with the temperature: a CPU that idles above 50°C or hits 95°C under load is running too hot, and the cause is usually dust, a bad cooler, old thermal paste…

Knowing how to apply thermal paste correctly is one of the easiest wins in PC building — a pea-sized dot in the middle, a cooler pressed down evenly, and your CPU can run several degrees cooler than with a bad…
