To avoid the noise of a venting computer, this German hardware d00d set his computer in a fishtank filled with lettuce oil. No more noise!

what the hell?

without cooler and a fast cpu it can even make some grilled potatoes lol

Well, if he circulates and cools his oil, it would cool like a fridge on steroids... but if he does not cool or refresh it, it would become a polymer after a long time...
