Hi, I'm getting really weird temperature readings on my i5-4690. This is (I think) causing my BIOS to spin my fans far too quickly. Temperatures CPU 37 °C (99 °F) CPU Package 78 °C (172 °F) CPU IA Cores 35 °C (95 °F) CPU GT Cores 78 °C (172 °F) CPU #1 / Core #1 34 °C (93 °F) CPU #1 / Core #2 33 °C (91 °F) CPU #1 / Core #3 33 °C (91 °F) CPU #1 / Core #4 35 °C (95 °F) PCH Diode 40 °C (104 °F) GPU Diode 31 °C (88 °F) This is at idle. Why is the integrated graphics (Intel HD 4400) running so hot when the cpu cores are all fine? I have a good cooler (Coolermaster Seidon 120M). As a result the 'package' temperature is over 40 degrees hotter than the hottest core. It is even more odd because I have a discrete graphics card, so I don't even use integrated graphics. What is the problem? Bad temperature sensor? Faulty CPU? Bad application of thermal paste? Many thanks for any help
