Can laptop heatsink break down after 8 years?

i have sony vaio vpcz1 (i5 560m, gt 330m) and overheating issues. To my surprise, there was a guy (nickname`s paloseco) with the same problem, so i will just copy his messages (mainly bcause my english isnt very good).
"has been working perfectly since 2011 or so, until a few weeks ago. When I have the power plan to performance, and the Maximum processor state to 100%, it randomly shuts off several times a day, specially when I put a high load on the processor, which can be doing easily opening several Chrome tabs.
1. Yes, under load the fan speed increases.

2. Yes, with two cores at 100% use the air is coming out of the vent and I can feel it slightly warm, at say 7 inches (19 cm) in a straight line from the exhaust grid.

3. The air blowing out of the vent is hot, I'll post more temperatures information next."
Im too newbie to take apart notebook and change thermal paste, so i gave it to computer master. After a few days he changed thermal paste (he might be lying, the price was too cheap), got rid from dust. But it didnt solve the problem. Everything is still the same. Then i asked him again, should i buy liquid metal and he will apply it to cpu and gpu. He said that this way wouldnt help and heatsink is the problem. Is he wrong?

 

<If> he really changed the thermal paste and the results is still exactly the same it looks like punctured heatsink pipes. Aka then you will need new heatsink.

 

Does it matter that my gpu and cpu are attached to same heatpipes, but gpu can pass the stress test (occt), meanwhile cpu cant even run it. And the released air usually is very hot

This smells more like he didn’t change thermal paste. I would open it up myself. See if you find a YouTube video guide (re-paste/swap parts) for your notebook model. Do the job yourself.

 

Hello!

I was in the same boat as you. I initially paid >$100 to do some cleaning due to constant overheating issue on my Vaio to some 'professional,' I found on Yelp (I didn't know better four years ago ), but that only did so much. Long story short, I got scammed out of >$100 and was heavily coerced into writing a good yelp review before the service was even finished. Yikes! The overheating problem came back after just couple of months.

Unfortunately, the best bet is to just do it yourself.

I finally had enough and came across this video and was able to successfully replace my thermal paste with no issue... out of all videos available, I found that video to be the most clear and easy to follow. Just remember to be patient and never rush into anything! I'd heavily recommend you to download the video and use VLC to orient the video properly.

Also, be sure to check all the cables are in place when you're reassembling everything. I was frightened when my screen didn't turn on once I was finished reassembling. I carefully re-disassembled everything and found out that my video cable wasn't connected.

Now the notebook is my daily driver with no overheating issues! Absolutely worth it, and I think I got at least another 4 years on this thing.

Keep us updated on how it goes.

 

Its good to see another vpcz1 owner) I have some questions. Is it necessary to tore tape on mobo that holds wires? Did you tried to replace thermal pads between gpu and heatsink with copper shim with liquid metal? Do I need to change other pads (on vram and etc)?

Haha, same to you! There's not many of us left out there

To answer your question, I only did as almost exactly what the video demonstrated, so yes I did have to tear the tape for the wires, and I didn't have to replace the thermal pad, because fortunately mine didn't get torn during the procedure.
My GPU temp is currently fine, but in case I do need to replace the thermal paste again in the future and my thermal PAD goes bad during the procedure, I bought some copper shim on Ebay. I did use a thermal paste (generic brand from Best Buy - Insignia) instead of a liquid metal for the CPU. Also, the video doesn't separate the fan from the heatsink for vent cleaning, but you can easily disassemble the fan by removing the black tape (just be sure to reapply tape with a black electrical tape once you're finished). My tape was old, so it was pretty crusty and weird, but it felt great getting all the gunk out of that vent!

From what I know is that if you damage your thermal pads during the separation of the mobo and the heatsink, you need to do the thermal paste > copper shim >thermal paste method if I remember correctly as for the gpu...

but anyone please feel free to chime in if I'm wrong since I'm not too knowledgeable on this subject.
