Modder discovers that putting a GPU in the 'wrong place' can deliver a 19 degree cooler hotspot

What happened

This process began with an entirely conventional setup with the CPU (the general-purpose processor at the centre of a computer) cooled by a 360mm AIO, and the triple-fan RTX 3080 slotted directly into the usual PCIe expansion slot. In PC DIY it might still be worth challenging convention, as TrashBench shows with his GPU (a chip built for many calculations at once, used for graphics and AI) hotspot getting up to 19C cooler.

It might be reasonable to assume that desktop PCs are built in a certain way due to decades of evolution and optimization. In this latest video, completely ignoring the accepted norms of GPU placement delivered up to a 19°C hotspot temperature reduction but adversely impacted CPU temperatures .

However, some more tweaking resulted in a 14°C reduction in hotspot temperatures and a 3.3°C cooler CPU. TrashBench's plan was to prepare his RTX 3080 desktop PC and "test it normally, then start moving s*** around."
