Yesterday I fixed up my dad’s friend’s computer and had a bitch of a time getting the computer to work right. I originally built the machine and had no issues until I tried updating the OS.
This is the key though, the MB is reporting super-high CPU temps. The MB is the ASUS CUV4X(-L I think) using a 600 Celeron-E cpu. The BIOS reports the CPU temp at around/above 200 F (about 95C). This is much to high but the weird thing is, the CPU doesn’t seem hot.
I pulled the CPU out of the socket, checked the fan and heat sink (both OEM and working). There is pleny of thermal grease as well. I held my finger on the edge of the CPU and heat sink hoping to get burned, nothing. It’s just warm but not hot anywhere around the CPU.
The CPU temp and voltage from the PS are changing and both are in the red. The voltage seems to change in line with the heat (I understand about heat and resistance).
So, is this just a MB error? Do these sorts of MB throttle down voltage in responce to the reported temp?
From those with this CPU, does your BIOS report this as normal operation temp? My AMD runs at a quarter of this temp (but then again I have 7 fans and an aftermarket copper heatsink). My last Celeron operated at about 50 C, not nearly 100!
I’m no longer experienced with Intel CPUs and don’t know anyone with one 
95C is way too hot, if the CPU was really that tempature you will be noticing it. Infact that tempature is enough to fry the CPU.
If the CPU was really that temp then the heatsink would be VERY hot. If you can put your finger on it and not get burned then its most likly just the tempature sensor on the motherboard going bad.
CPUs generally are not willing to run that hot. Above 150F it should be locking up.
If you are using a third-party application to read the temperature (e.g., MBM) the program might be reading the wrong sensor.
It is also possible that your temperature sensor is malfunctioning. They are not known for being reliable.
I wonder if the Heatsink is properly seated.
On the base of may heatsinks there is a step ledge desigend to clear the socket, it’s dead easy to get this slightly out and the result is the heattsink does not sit correctly on the CPU.
You should be able to observe the imprint of the CPU in the thermal grease, if you do not see a perfect impression of it then misalignment of heatsink is very liekly, it will show up exactly as you describe.
The grease was well smeared so I know it was touching correctly. I was concerned about that first (I had installed the CPU originally and know first hand what happens if you screw that part up ). The heat sink was about body temp and there was no other noticible heat coming from the board (this was after a 4 hour run re-installing Win98).
At least I know the CPU could not have been running that hot. I was surprised at first thinking maybe Intel was making CPUs out of Adamantium Running at 200+F is very impressive.
I’ve set all checks to Ignore in the BIOS. Thanks guys for the help!
