Yet another tortured CPU....

From the outer look, it seems it is not extremely "choked" right? Consider a normal dust blocked air flow of a CPU fan and heatsink right?

When i took off the fan, can a clear view now? the dust have been united there for quite sometime i think, no wonder the CPU system running slower and slower now. It's too hot and affected the nearby transistors been swollen. Conclusion is that the motherboard will not be function well, and kicking system to be restarting always. But for this case, the CPU is burn too...pity for my customer. I don't want this to be happened too...
