I bought a Zotac GTX 970 (standard non-oc version) about 4 months ago. Temps have been very high for the past few days while on heavy load gaming (witcher 3, gta v) -going close to 85C at times. Initially I thought it's due to the heat lately- but only today I realised the true culprit-- that one of the fans is not spinning properly-- and by that I mean it's spinning much slower and at times it seems to be stalling about every 5 seconds.
Is there anything I could do to check what's going on in there by pulling out the card? Or shall I take it straight to the shop to get it checked? I have no idea what caused this, and Google is leading me nowhere with this
