One core of four (CPU A Core 2 Diode) Runs Really Hot
I have a Power Mac G5.
Model Name: Power Mac G5 Quad
Model Identifier: PowerMac11,2
Processor Name: PowerPC G5 (1.1)
Processor Speed: 2.5 GHz
Number Of CPUs: 4
L2 Cache (per CPU): 1 MB
Memory: 12 GB
Bus Speed: 1.25 GHz
Boot ROM Version: 5.2.7f1
Lately the fans run loud so I installed Hardware Monitor and it appears that CPU A Core 2 is running into 90°C while all the other cores are staying below 60°C.
Can this be right? Wouldn't CPU A Core 2 be under the same die as CPU A Core 1?
Can anyone say why this might be happening and how I can fix it? I build computers and I'm not afraid of pulling the LCU out and re-applying thermal interface, but it sounds like the design of the computer might make that difficult.
Is this a good question?
