Processor overheated and melted?

[tommynguyen02]

I have a Compaq Presario V5204NR and I noticed I have been overheating issues as the laptop would get hot and just shut off.  I decided to take apart the laptop and inspect it since blowing air into the fan didn't seem to help any.  Upon opening I found the problem.  A ball of lint and dust had built up between the copper cooling fins and the fan.  What caused this was the sticky portion of the "tape" cover that directs the air from the fan to go to the copper cooling fins and out the exit.  I will post pictures in a bit. 

Does anyone know the nominal temperature of CPU?

Varies quite a bit depending on make/model of processor.  Since you have the laptop open, you should be able to pull the heatinsk and see the exact model number of the processor in that machine, from there you're a quick google search from finding the max temp.  usualy you want to keep them under 60-70C, but that's a very broad answer.  Most modern laptop processors will slow themselves down and cut their power usage when they start to get too hot, so you'll notice a slowdown and even shutdown before they burn themselves up.

Also, that dust ball is very common in laptop coolers.  The only real way to keep it from happening is to blow air backwards through the fins reasonably often to keep the dust layer from accumulating to start with.  Also if you use it on your lap or in bed, fuzzies from clothes will get sucked in there an make things worse

I searched the internet to find more info about the CPU and the temps I'm seeing are normal.  I downloaded Speed Fan to monitor my HD as well and CPU temps.  I wished I had did a temp check before I cleaned out the cooling system for comparison.  

Thanks for the info!
