Per-Module GDDR7 Temperature Reading Unlocked on NVIDIA GeForce RTX 50 "Blackwell"
Quick Report
The modding community has successfully unlocked per-module GDDR7 temperature readings on NVIDIA's GeForce RTX 50 series Blackwell graphics cards through a new MSI Afterburner plugin. Contributors including Paulo Gomes, Unwinder, asder00, Mumak, and olealgoritme collaborated to create the Hotspot.dll plugin, which accesses thermal sensors previously hidden inside memory ICs.
For example, on the GeForce RTX 5090, there are 16 GDDR7 memory modules, each with a 2 GB capacity, enabling 16 individual temperature readings. This advancement is particularly helpful for troubleshooting and verifying proper cooling, especially when thermal pads wear out or are missing, as improperly cooled memory can overheat and degrade rapidly.
