Circuitry and components breaking due to overheating

post #1 of 2
Thread Starter 
Just double-checking what I'm assuming:

It's theoretically possible to break or damage any part of a laptop's circuitry due to overheating right? I have a 2008 white macbook and i noticed every time my computer starts heating up (which it does at an alarming rate nowadays), the wireless connectivity starts crapping out and eventually refuses to work. At times, after restarting it tells me there is no wireless module installed. After a few restarts it'll come back but to me it means these two things (or one of them at least):

My laptop is heating up too much
My laptop is way too old.

So at this point I would *want* a new laptop but that isn't possible till i get to college. So do you think it's an actual hardware issue, which my laptop is breaking down, or it's a heat issue and the hardware itself is fine. I realize it could be a combination of both, but I would much rather save a trip to the apple store and just reduce my laptop usage and also save me a few hundred dollars (probably).

tl;dr
Wireless craps out when laptop heats up. Actual circuitry issue, or heat is just getting too much?

To answer your first question, yes any electronic part can brake down if it heats up too much. Wireless cards are particularly hot chips as far as I've seen of various laptop and USB adapters. Normally if something overheats once, it turns off, cools off and it's all good. If it heats up many times it can break down permanently.

A 2008 laptop isn't old, but slim laptops have a problem with building heat in the chassis and the Mac is no exception. My advice is to buy a notebook cooler; usually on the 20-25$ range they can lower the temperature of the underside by so much that the laptop can be used normally. I have a colleague with a 2010 unibody MBP and she's forced to use a cooler to be able to do some scientific computation, it just heats up and shuts down otherwise. Don't really agree with her punishing that laptop with such workloads, but as long as the temperature doesn't creep up everything works well.
