So i have a, PNY GeForce RTX 3070 8GB XLR8 Gaming GPU which has a 3 Year Warranty, i need clean the heatsink as it is caked with dust and noticed the temps increasing over time. I have tried using compressed air but only shifts a little of the build up of dust, 2 screws on the GPU has warranty stickers on them. Here in the UK if i remove these stickers does this void the warranty on the card?
