We all know Red LEDs make computers faster while blue LEDs make them run cooler. Just how much of a performance-bump do you get by using a red LED on your CPU cooler? We have done the benchmarks and found the answer.

Our test-setup consisted of a standard micro-ATX motherboard with a Ryzen 2600 CPU and an average after-market heatsink with a 120mm fan mount. We timed Linux kernel compilations with a regular fan and a red LED fan.

Extensive testing of kernel compilation with a both a regular fan and a red LED fan found no measurable difference.


It would appear that the performance impact of red LED fans is zero. You are clearly better off spending that extra money on a better heatsink or other system components.
