So i actually use these for VRM and VRAM on older gpus, think rtx 20 series, gtx 10 series, maybe even rtx 30 series. Things like that. You can also cut them for m.2 heatsinks and such. These are best for that. Making sure it pushes heat away from parts. So it is best to use it on GPUs where their thermal pads are old and unusable. (crumbly or doesn't feel soft and malleable.)
So yes. This pack is quite good for basic stuff. And proper gpu care. Don't use it on the die, i always use proper thicker thermal paste with a higher rating to give theGPU room to breathe.
