We all know just hot GDDR6X memory chips can get on NVIDIA's GeForce RTX 30 series graphics cards but modders have come up with a solution.

One of the key upgrades for the high-end NVIDIA GeForce RTX 30 series graphics cards was the use of GDDR6X memory modules. Offering over 18 Gbps memory speeds, these memory chips are the best in terms of bandwidth performance but they also happen to get really hot, reaching over 100C in some cases.
