Earlier in the month, we reported on TechTuber and extreme PC modder TrashBench and their direct-to-die GPU watercooler project. Well, they’re back with another GPU cooling experiment, involving an NVIDIA GTX 1080 Ti, its cooler, and a massive CPU cooler.
The project starts, as these things usually do, with TrashBench choosing the sacrificial lamb to their bush-mechanic monstrosity. In this case, they took the GPU cooler of an ASUS GTX 1060, removed part of the fins around the back of the coldplate for the CPU block, and then attach it.

Just as before, the heatsink TrashBench took from the GTX 1060 was for control. As for the design, the idea was that the original heatsink and heatpipes would still do their job, while the CPU block would act as a second path for heat to escape.
Once TrashBench was confident of their modified work, they then proceeded to a GTX 1070 from the same brand and same lineup, presumably to keep the project outcomes uniform. Of course, it goes without saying, there was a lot of trial and error, which also meant breaking out the Dremel cutters.

Now, TrashBench used a single fan CPU cooler initially with the GTX 1060, with a 9°C drop in temperatures. After that, they switched it out with a dual tower model, to which the card showed practically identical performance numbers.
Applying the now final dual tower CPU cooler model to the GTX 1070 and GTX 1080 Ti, the performance gains – overall temperature, heat generated, overclocking gains, all that jazz – were significant. For the GTX 1080 Ti, the dual tower CPU cooler lopped off 24°C overall, while the GTX 1070 saw a drop of 21°C in temperatures.

As we mentioned, this isn’t the first time TrashBench has ever conducted experiments such as this, and you can check out their YouTube channel if you’re into this sort of thing.
