I have a Corsair H105 and a 6700k. I also have a GTX970. My temps have always been great. About 25C to 55C at extreme loads I believe. I had a case fan going bad. Replaced it with a noctua fan that actually blows more air. Using Core Temp, I checked my CPU temp. Looked good. About 25C idle. Every time I open a program, it jumps to 60C upto 70C sometimes. I have seen it go higher too. I reapplied thermal paste. (Noctua NT-H1) No change. MAXIMUS VIII RANGER mobo. In bios, under monitor I think, water pump has an RPM so it looks like its running. What else could be wrong? Could H105 be going bad? (doesn't look like)
