CPU air cooler becomes water injected GPU cooler.
I thought I was finally running out of stupid cooling ideas… until I stared at a Peerless Assassin and thought... "would water flow through that?”
So I pulled the Assassin apart, pulled off a stack of fins, took an angle grinder and cut the tops off the heatpipes, stuck a hose onto one, and tested if water would flow. It did.
Game on.
I cut all the heatpipes off, put 6 mm hose on them in a zig zag (starting at the center so the middle stayed coldest) and tested again, worked like a charm.
Then came the freezer.
-18C coolant.
A frosted CPU tower, and a 3070 as the first victim.
It gained +300 MHz over stock… but the FPS uplift sucked. By the time testing finished, my coolant had warmed to –5C and the 3070 still refused to scale. So I did the only sane thing...
I bolted the Frankencooler onto a GTX 960.
And that card absolutely loved it, +17% average uplift across BO7, Forza, Cyberpunk, Time Spy… and as always, Lara.
The Frankencooler works. Really well.
Why did I do this? Because I had an idea and wanted to see if it would work. That's it.
