Overheating

I have an almost 3-year old T500. Lately I've been noticing that it seems to run a bit hot. Speedfan reports that the core temps are just around 50F at 23% avg utilization.

 

1. Is my observation/concern correct that it might be running too hot?

 

2. If so, I'm wondering if airflow got clogged by detritus (dog-hair, etc.) over the past 3 years and if there is a simple and safe way to open the laptop and see if I can clear out some dirt from the air flow path?

 

3. Could there be another explanation?

 

Thank you all.

Re: Overheating

Yes, and I'm driving dual monitors - the laptop screen and an external monitor attached to the port replicator.

But even when I'm using the laptop in other locations, I sense that it overheats, especially when I'm playing cpu-intensive games.

Re: Overheating

Are your graphics drivers up to date?

With the switchable T500, an older driver may cause overheating in certain circumstances.

You'll probably want to take off the keyboard and clean out the fan. Here're the instructions:

Re: Overheating

With another T-series thinkpad that I owned, I saw the same effect after three years. Spraying the fan with canned air dramatically improved the cooling performance.

 

Lenovo publishes a hardware maintenance manual PDF which tells you everything you need to know to disassemble the machine. I disassembled it to the point where I had easy access to the areas around the fan, but I didn't remove the CPU or remove the system board from the case (both are bad ideas.)

Re: Overheating

@ColonelONeill: THanks. Holy cow, that's a lot of paper. The disassembly instructions I need cover more than 20 pages!  Smiley Sad 

 

Oh boy, it may be easier to send it in for warranty work, it's still covered under the extended warranty.

Re: Overheating

if you got warranty then let the warranty depot worry about fixing this issue.
