CPU cooling question
Lately my Sony Vaio laptop was misbehaving: the cooling fan was going crazy. Just a few minutes after starting up, it would turn to the highest speed and stay there, then in 10-20 minutes the computer would shut off. So I took it apart and found a one centimeter layer of compacted dust obstructing the airflow to the CPU heat sink. When I took the heat sink off, it came out with the CPU "glued" to it.
I probably could put the CPU back in place (together with the heat sink) but I was wondering - should I take it off the heat sink and replace the thermo compound? Does this compound degrade over time? The laptop is about 3.5 years old. Thanks, |

I sure "can" try... I'm a certified electronics technician...
However, my question is, "SHOULD" or should I not replace the old thermo compound? The heatsink is firmly attached to the CPU. My expertise is with other electronics, not computers... |

It's not difficult. Just make sure you get a thin, even coating of thermo paste on there. I prefer Artic Silver over the 'grease' kinds that are either like graphite or lithium.
There are plenty of sites online with instructions for the process. After 3+ years, the paste/grease on there is going to be fairly dry and not transferring heat the way it did when new. Eric |
