Most gamers probably know that an overheating GPU can cause thermal throttling, effectively stealing performance from right under their nose. That’s why they are fixated on keeping the GPU core temperature under 80℃. Whether it’s using MSI Afterburner, HWiNFO, or something else, PC gamers will keep an eye on the core temperature, but ignore another important one. The VRAM temperature is also linked to the optimum performance of your graphics card. If the GPU memory overheats due to excessive load, lack of airflow, or expired thermal pads, your gaming experience will be reduced to a stuttering mess. Most people ignore the VRAM temperature completely, and find something to blame when their performance drops despite a seemingly okay core temperature.
