Hi Guys, I was wondering if you could please help me out with something. I have just recently finished building my new HTPC and I am using the AMD Sapphire RX 580 Nitro + 4GB DDR5 as my GPU. Yesterday was the first time I actually sat and watched my first movie and after 2 hrs I went to turn the HTPC off and just to check the overall temperature or the case etc (Silverstone GD09B) , to my surprise it was extremely hot. I was a little worried so opened up the case to see where the excess heat was coming from. Upon doing so and touching the graphics cards back plate and heat pipes, I realised this was the issue. The Card was so hot I just couldn't understand why. I installed the Sapphire Trixx software where you can adjust fan speeds etc etc but anything over 50% is too loud. I think at default it's set to Automatic which keeps the fans off up untill around the card reaches 60 degrees then it kicks in. I just can't understand why this card gets so hot with just movie viewing and nothing else? I haven;t and won't overclock as I am only using for movie viewing. Is this normal? are there any recommendations that you could please suggest or does this sound like I have a possibly faulty card and or shall I replace it ? Prior to this card I used to have a RX560 4GB and that never put out heat anything near to this card. I am worried and I don't want to have a card pumping out excessive heat everytime I sit to watch a movie.. Your help and advise is greatly appreciated.. Thank you ..
