Can you give me thoughts on what I should do next ?
1. CPU is dead, replace
2. Heatpipe is not installed correctly. (any thoughts/questions on how to install it differently)
3. Heatpipe is not working (any thoughts on how/why) --e..g there's no sign of fluid inside or leaks.
3. Some other cause for overheating laptop.
I have an ancient, much abused win7 based inspiron laptop. It is overheating badly. CPU is the socketed i3-330m.
I can see the frequency throttle back to 38% of max under 50% load as the HWMONITOR reported CPU temp hits about 87-88C (t-junction is 90C for this chip). If temps go up higher the laptop shuts down.
The fan was making noise, so I bought a new fan and opened up laptop to replace it. I expected to find a ton of dust leading to overheating. Nope, there is a long copper heat pipe from the CPU to the fan, and the fan area was clean.
I replaced the fan anyway. New fan works. No more bearing noises. No change in temps.
I removed the heat-pipe from the CPU. removed the old paste (which was really heavily applied, thick), and replaced with arctic silver 5. No improvement.
I Re-did the paste on the CPU a second time. Removed the prior arctic silver and added new. The spread pattern on the CPU and heatpipe looked good from the first attempt. No improvement with the second attempt.
This laptop ran 24x7 grid computing for a few years and likely was overheating for a decent percent of that time, which is the only reason to suspect the i3-330m is running hot.
Seems the overheating must be from a failed CPU (leaking current and overheating), bad install of heatpipe, or something broken in the heatpipe assembly.
My next steps
I can get a new CPU for $7 from ebay (not much market for these cpus I guess). If the CPU is leaking current this could be the solution.
Here is what the headpipe looks like. https://www.ebay.com/i/112262958671?chn=ps
I can't think was could go wrong with a heat-pipe, and I can't see why my paste job is bad. Used Heatpipes are under $10 plus shipping.
Any thoughts ?
