Why Purchase a New CPU Cooler?

CPU Cooler

This question arises quite often and rightly so. When a CPU already has a cooler/fan, why should you invest in a better one? This is because the in-built cooler is usually not powerful enough to handle overclocking. If you do it once in a while, you can stick to the original product but if you frequently overclock your computer, you will definitely need something stronger to avoid overheating. A good cooler will bestow upon your CPU the following benefits:

  • Increases its lifespan
  • Keeps it stable
  • Makes sure there’s little to no noise
  • Improves its performance

Why Choose Air Coolers?

CPU coolers are of different types. The most popular ones are liquid coolers and air coolers. The latter got a bad rap because they did not reduce the noise level all the way to zero. Liquid coolers, thus, were supposed to be better and more efficient. However, the latest models have surpassed expectations and are just as good as liquid coolers in terms of performance. What’s more, they are cheaper and easier to install. This is why we suggest that you choose air coolers over liquid coolers.
