making enclosures for electronics
anyone done this
how does the wood hold up over time i am not expecting a lot of heat as it is a low power device but it will be warmer than ambient sometimes and then cooler at other times i found a project that is using wood for a custom laptop but i am more interested in the longevity factor for wood in this application |

But, it does not last forever... i am not expecting a lot of heat as it is a low power device but it will be warmer than ambient sometimes and then cooler at other times i found a project that is using wood for a custom laptop but i am more interested in the longevity factor for wood in this application |

What are the chances that the next laptop has the identical dimensions? |

I always drilled lots of holes for air circulation. Put the holes so that the heat can escape upward and some cool air can come in below the heat. It should be OK. If it does warm up a bit, you can always install a fan. They have some very quiet fans for computer now. |

Look for CoreTemp, a free program that reads the temperature of the processor to see just how hot the specific device runs. The dual core Intel processor in my laptop can hit 172F or more when working hard. This is in conditioned space that's 78F. Expect higher internal laptop temperatures if the ambient temperature is above 78F. |

They are old and I can't speak to how they held up. (He hasn't answered that question yet. I'll let you know if/when he does.)

That's generally measuring Tj (Junction temperature, the highest operating temperature of the actual semiconductor) or Tc (the temperature of the processor chip case itself). The air temperature within the laptop is significantly less, assuming that the heatsinks, cooling devices and ventilation openings are functioning correctly. |

If you're on a battery, having a fan could mean significantly reduced run time. It might be worth considering a switch (automatic or manual) and making sure your case is as open as possible.

John I agree. I've seen many a Fender, with wood cabinet, guitar tube amp that ran plenty hot. I never saw the wood destroyed. Most of the old tube radios had wood boxes. Didn't seem to hurt them either. |

Expect higher internal laptop temperatures if the ambient temperature is above 78F. It depends on what that's measuring. If it's a thermal diode on the processor chip itself, 172F isn't all that hot (80C). The processor should be able to take at least 105C (~220F) or perhaps 125C (~260F). Of course, the key is understanding exactly what is being measured. Without that information you have no information. |

I never had the RF interference problems everyone predicted but that is probably due to the way IBM made the boards." |

Without that information you have no information. Exactly so. In most cases what's being measured (because it's what's we can really control) is the case temperature. But as you note, some devices have an internal sensor measuring the die (junction) temperature. It would be unusual to find a case temp rating above 85C in a commercial grade product. That roughly corresponds to a junction temp of 105C. Automotive grade parts are usually spec'd for a case temp of 125C. There is a significant price premium for that temperature grade. John |
