CPU evaluation

Hello Notebook Users

Does anyone know if my CPU pins are too pale and if the yellow mark near the die cover is a sign of overheating and potential middle term CPU failure?

Thanks in advance

 

Are you having problems with it? Cause its pretty much impossible to tell without dedicated inspection equipment, which cost millions of dollars.

 

I have no problems with it.

I am just scared about this yellow spot in the die cover.

Maybe too much thermal paste was initially applied in this area or maybe not enough?

I used this machine for 6 years without cleaning it and when I opened it I noticed a lot of overheating signs

I had to soak the CPU and almost the whole MB into Ethanol to remove coil and sort of carbon ashes

The pins look pale after being soaked in Ethanol, and I don't know if the Ethanol removed gold from the pins or just yellow dirt

In another hand I also soaked RAM into Ethanol but the pins are still dark gold looking

I don't even know if it's real gold on the CPU pins and how the original color was

Thanks in advance

 

Gold can't be dissolved in ethanol, so no worries there. Just reapply some fresh thermal paste and let it continue working. There's not much you can do at this point.

 

For the ram, you can use 99% isopropyl and scrub the pins with a toothbrush if you're that concerned. But if it's all working fine, just repaste and put back into the computer

 

Thanks for your answers

I literally soaked the RAM as well as the CPU during aprox. 1/2 hour in Ethanol

I used a soft paint brush to clean everything out

I prefer Ethanol over Isopropyl because it's cheaper and look more volatile, faster to dry

I am waiting 4 the thermal paste: ShinEtsu x23

I tried Artic MX-2 and hated it: too liquid, I had to clean again residues tonight...

Also I believe MX-2 is abrasive

Thanks for your answers, I will post pictures of the machine when restoration will be over

This is a very nice ThinkPad W520 with i7 XM CPU

With SSD drives this is pretty much exactly like the machines they released this year

Also, Lenovo parts are cheap in Europe so I bought new covers!

I love old ThinkPad, they were the best notebooks ever made

 

Today i cleaned another machine and accidently bent a pin from the CPU

After quick repair, it fit the socket without any gap

Should i be worried about this? I don't feel touching it again

Thanks in advance

 

If it ain't broke, don't fix it?

@ThinkpadUser858 if it fits, it will work.

 

Thanks for your answers

It fits the socket perfectly I think.

The socket was just harder to close than on my other machine but very little.

After closing I checked with a magnifier and it was still ok

I have trouble to understand how a socket works mechanically

Is it supposed to fix little pin bents when it closes?

Does this means the bents can be improved over time with temperature variations?

I am still waiting for the paste... I can't wait to power on

This machine has been an hassle to clean (thinkpad w540)

You have to remove the main board to access the fan!!!!

 

The pins are inserted into holes with contacts on them. As long as the pin is still physically attached to the CPU and makes contact with the other metal part of the socket, electricity will flow. It's normal for it to require more force to insert because of the bent pin. Just don't mess with it too much, trying to unbend the pin may lead to breaking it if you aren't careful, so leave it in the socket and call it a day if it works.

 

Which goes back to the age old wisdom of... "if it ain't broke, don't fix it"

 

Well, yeah, but the OP wanted to know why and someone already said that

 

OK this CPU works

cleaning improved so much the temperature!!

this is amazing can you hear me

 

It always does.. Its the 1st thing you should do when your laptop is overheating!
