Been building me own puters since the days of the 486 Mr Milo, I know how to remove and replace CPUs/heatsinks, the one in the photo has been yanked and cleaned twice since it was built.
Only ever had one CPU fry itself on a grossly overclocked pentium, fan was stalled by the IDE cable,mind you it did die very swiftly,spotted what had happened almost instantly and grabbed for it but too late.
