I have had my pc for 9 months now and the temperature seems to be rising for some reason for my i5 at idle In the bios it is at 45c. I don't understand why this could be I recently applied thermal paste (arctic silver 5). I also build my little brothers pc and his idles at 26c in the same house however his CPU is the i5 4440. I don't know my room temps but I do live in the uk and it never very hot here. I think it's like 18c today. I have a zalman z11 plus case with 5 case fans and 2 92mm CPU heatsink fans (CM TX3). My GPU seems to be getting hotter than it should I set it to aim for 70c but it went upto 80c yesterday. It's a evga 770 sc acx 2gb.
