Exclamation Cpu @ 100*c

My brothers PC's motherboard and GPU are running at steady temperatures around 40* but his CPU is running at around 100*
His processor fan is also running at around 3800 RPM.
I don't think he has a chassis fan.
What is the problem and why is the CPU temperature so high?

Help please!

CPU = Intel Pentium D 3.4GHZ
GPU = nVidia GeForce 8600GT
PSU = 480W

100* C? Thats way too hot for a CPU and I'm suprised it doesn't shut down. Assuming this is a build, did you apply thermal grease to the heatsink before placing it on the CPU? I can't imagine any other reason why a CPU would be running so hot.

faulty sensor? where did you check your temps?

My computer uses 1.5A-load, .8A-idle, .65A-standby, .05A-turned off on 125V.

No this was a pre-built pc. Only difference was I upgraded the PSU and GPU.
I checked the temperatures on PC Wizard.

Go into the BIOS, to get the most accurate reading of temperatures. If it matches the program with 100C, you're in trouble. I'm surprised the CPU hasn't melted or burned either.

my guess is that the HSF retension system is loose....

You probably hit it or knocked into it when you changed out the PSU....
Reverify that ALL 4 points of contact are in COMPLETELY and SECURED IN!

You see those 4 black retension points? Make sure they are in all of the way and locked in.. To lock them in you need to take a screwdriver (or your finger) and secure them by twisting. Look at the arrows on each point.
