Liquid cooling is an excellent way to prevent your PC from overheating. Unfortunately, most people can’t just dunk their PC underwater and overclock their rig to the max.
Some people, however, can do exactly that.
Maximum PC recently built a computer that is completely submerged within a fish tank. All PC parts are surrounded by water to create a perfectly-cooled rig which is also remarkably noise-free.
Check out the video below:

As you can see, the rig is more than just a pretty face. It’s also got the hardware to run some pretty impressive games at good framerates.
The Maximum PC “fish bowl experiment” used a Swiftech pump, compression fittings, and a 240mm radiator, all of which are popular with liquid cooling aficionados.
However, the similarities end there. Max PC also used acrylic framing and container PCs as well as an internal temperature gauge and an unprecedented “several gallons” of mineral oil.
After pouring all that water into the tank, Max PC inserted the rig directly into the tank. Once the rig is powered on, purple LED lights make the entire contraption look awesome.

The only thing this fish tank PC is missing is – you know – fish. But I’m not sure fish can survive in mineral oil. And of course, fish poop would probably wreak havoc on a motherboard.
Unlike other liquid cooled rigs, the fish bowl PC wasn’t totally silent. It actually made a sound like a “babbling brook” as the oil circulated through the pump and the radiator before re-entering the case.
The fish bowl PC was expensive to build and it’s also very heavy – over 50 pounds with all the oil inside. However, it does do an excellent job of cooling the PC no matter how hard you’re pushing your hardware.
It’s not a practical machine, but if you have money to burn and plan on staying in one place for a little while, then this thing is absolutely awesome.
Thanks to our friends at Maximum PC for doing something crazy!
