Check out this Totally Bonkers liquid-cooled gaming PC with 69 water blocks

Back then liquid cooling meant “custom loop”, but you only had to worry about the two or three processors at most. These days, when you do custom loop liquid cooling, you have to cool almost all the main components on each individual board. That means cooling memory and power supply hardware as well as processors. For that reason, most motherboards use designs for liquid cooling as well as full-coverage water blocks that fit nicely on graphics cards.

Obviously “most” doesn’t include the aptly named /u/psychoOC on Reddit. The user has posted some photos of his custom liquid-cooled PC that was done up the old-fashioned way, with no less than sixty-nine (nice) separate water blocks over nearly every single heat-generating component in the system.

Most radiators are mounted under the desk.

The plethora of processor coolers are split across two separate loops powered by six D5 pumps, and cooling itself is provided by six radiators, including one 240mm and five 360mm. Over two liters of coolant fill over 100 feet of pipes in the building. Funnily enough, in addition to the PC itself, the UV light sticks – which make the coolant and 2004-vintage fluorescent-orange fans glow – are also liquid-cooled.

The machine has a preponderance of powerful hardware: an overclocked Ryzen 7 7700X, a Radeon RX 7900 XTX and four sticks of hot-clocked DDR5 memory. Despite that, it remains cool – PsychoOC posted a stress test screenshot showing that almost every component in the system rests comfortably below 30°C. Perhaps that shouldn’t be a surprise given the amount of hardware involved in cooling, but it’s pretty impressive considering there’s no cooler involved, just air cooling.

The builder says that he spent “2 months of every night when (he) got home” to complete the machine, and amazingly, he apparently had bigger plans that had to be abandoned for the sake of time. He says he’ll post his overclocking results in a week or two, so maybe keep an eye on his profile if you’re curious about what these parts can do with 69 water blocks attached.
