Definitely needs replacing since it’s been exposed to air now.

Absolutely agree. It’s a must to replace old thermal paste to maintain good heat management.

@Noor
Does this also apply if you bought an old laptop model that’s new from stock? It’s been sitting on a shelf for 3 years.

23

By now, it’s probably more like thermal toast!

24

Be careful: the blue substance on the small chips is thermal putty, not paste. You can either reuse the current putty if it’s still viable or get a new one like the Cx h1300 from Amazon.

25

Now that you’ve opened it up, you definitely need to repaste.

26

Yes, definitely replace it.

27

Absolutely. It’s generally a good practice to replace the thermal paste every few years to ensure optimal performance.

28

For the CPU and GPU, use thermal paste, but for the chips, you need thermal putty, which is different.

Exactly, don’t use thermal paste for the chips. Thermal putty is specifically designed for that purpose.

Typically, yes, you should repaste, especially if you’ve just detached the heatsink. It’s a great opportunity to apply a high-quality thermal paste to ensure your laptop runs cooler and more efficiently.

34

Definitely repaste. Consider using a high-performance thermal paste like ptm7950 for long-lasting results.

35

Yes, I’d recommend replacing the thermal paste.
