If you’re still running a stock Intel or AMD CPU cooler, this is one of those upgrades I think you really shouldn’t ignore. Stock coolers are basically designed to let the CPU “run and that’s it,” and a lot of people assume you have to spend big money to get real gains. In this video I break that misconception, because you can get a legit jump in cooling performance for around $30. The cooler I personally recommend (because I bought it, researched it, and I’ve been using it) is the ID-COOLING SE-914-XT. For the price you’re getting a sturdy build, a single well-built fan, and a good-sized heatsink, plus solid compatibility with Intel LGA and AMD AM4 thanks to the included brackets. The real story is temperatures: my stock cooler had me sitting around 50–60°C, and with the SE-914-XT I’ve been down in the 30–40°C range. That’s a massive improvement, it can help prolong your CPU’s life, and it gives you some room for overclocking if your CPU supports it.
