You Probably Only Need Two Or Three Fans In Your Computer

When you build a computer, your case probably comes with a couple fans, with room to expand. But do you need to? The folks at Linus Tech Tips decided to find out.

There are a lot of different variables here, but they tried to test as average a configuration as possible to see how much different fan configurations affected temperatures. They found that, once you add a couple fans to the case, any additional fans do improve temperatures, but only marginally.

There are a lot of diminishing returns, that — depending on your preferences — may not be worth the added noise those fans can cause.

Of course, this changes significantly if you're overclocking, or live in a particularly hot place, but it's interesting to see some actual numbers behind a typical scenario. Check out the video above for the full test and results.
