Hi, I'm new to the lm-sensors world, but I have some curious results that I'm struggling to understand. My hardware is: Pentium4 2A GHz (Northwood, 512Kb cache, socket478) Motherboard is tricky to identify, but says 845CA so maybe it's a Jetway 845CA - that seems consistent with their specs and looks like an Intel 845 chipset. Sensor chip is a Winbond w83627hf. Software is Mandriva 2006 I started to get the system shutting down spontaneously, often overnight, but also while I'm working. No obvious application causing it. I did memory tests and that came up clean. So I decided to monitor CPU temperature and voltages using lm-sensors and KDE-SystemGuard. On the original hardware, with a standard Intel heatsink and fan, I got three temperature readings: temp1: 15-20?C temp2: 28-35?C temp3: 54-60?C I figured temp3 was CPU chip temperature, and a bit high: the cooler looked a bit grubby and I have a feeling that the thermal grease had been disturbed. So I looked for a way of cleaning this up, and found the Asatek Micro Chill cooler - so I bought one (retail therapy I guess...) Anyway, with this (big) cooler now on the chip, my readings are: temp1: ~20?C temp2: 30-35?C temp3: Started at 118?C (!) but is gradually working its way down towards 60?C Now I'll admit that I might have screwed the cooler installation, but I was surprised to see 100+?C on a running machine. So have I misinterpreted the readings, or maybe the sensors are not connected like lm-sensors expects... Anyone have any suggestions? One other thing, VCore1 is a bit fluffy, with occasional spikes to 1.8V and dips below 1.4V (should be 1.5V). Does that sound reasonable?
