Once again, I start yet another thread to ask a question about my 6970. Recently I installed an Arctic Accelero Xtreme 3 cooler on the card. No overclocking has been done yet. I've been experiencing slowdowns after a few hours of my PC running. Websites are slow and general performance drops. My temps on the GPU at idle are between 28C-30C and when surfing sites and stuff it's at 35C and while gaming never seems to go over 53C. Weird ping problems have been occurring also while online but I just can't pinpoint what is going on here. At first I thought it was my ISP throttling me and then I looked at the VRMs on my GPU. I installed heatsinks on them so they should be fine. I'm just not getting it, any ideas?
P.S I will not RMA the card so if it is dying, then I will just get a new one.
