Vpcz1 overheating problem

Recently my laptop begin shutting down randomly and suddenly. When I monitored core temps they were just about exceeding 100 degrees just before the laptop shut. I have resolved this problem partially by decreasing the maximum processor state to 70 percent so the core temps don't exceed 70-72 degrees. I would like to know whether other users of same laptop have faced a similar problem after 4.5 years of usage and what further steps need to be taken to avoid damage.

 

0. Some rogue program is creating high CPU usage.
1. Air passages blocked by dust, etc. so the heat is not being dissipated.
2. Fan not rotating freely - shaft needs cleaning and greasing. Same result as 1.
3. Thermal contact between cpu/gpu and the heatsink is poor. This is your problem if the laptop is blowing out cool air even when the cpu shows high temperatures.

This laptop is known for heating issues.

It has a fairly strong fan which wears out over time / gets gunk covered.

It already runs fairly hot standard, but after 3+ years this is nothing unusual.

Mine needed a fan replacement since the fan would sometimes not even start spinning after 3 years of pumping that hot air out like a mofo.

 

I'm happy to say that the Z13 in my sig - which has seen very little use in its charmed life - runs cool and rarely even causes the fan to run in high speed/noise, even when using the d-gpu and stressing the machine.

I bring this up not to brag, but to quietly say that I could be persuaded to part with it for a reasonable offer. It looks and performs essentially as if never used, despite having an April 2011 production date (the last month the series was manufactured). I got it 2.5 years ago in "open box" unused condition, and frankly couldn't bring myself to put it into regular service. It's never left my home, rarely even left my office. Any interest, feel free to PM me.

 

Well guys, I have air blowed the fan and now it idles at around 45 degrees, about 15 degress below what it was before. Another thing though, is the mechanical grrrr sound of this fan (and vibration in laptop body) kind of commonplace in this series?

 

45 is fine for idle, but what about stress, even moderate. "grrr" isn't common, but hi pitched whine is, and that's worse, as it ages. Grr may be loose mounting scre, if u can find it.

 

Cleaning and greasing the fan shaft worked for me to fix the rattling fan sound.

 

Will anyone be kind enough to label the missing components in this picture of vpcz1 internals?

 

I can't spot anything that's missing. If you want to know what a particular part is, put a number there and I'll tell you what it is.

Or you can download the manual here and see for yourself. The drawings are vector graphics, so you can zoom in as much as you like.
