Linux compilation benchmark on Ryzen 2600 with and without Red LED fan
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.
