CPU delid necessity by time

[TheJavatar]

Hello guys.

 

I have an Acer Aspire 5742G laptop which has a Core i5-460m processor. I think it is 6 years old now.

 

I have a Zalman NC-3000U cooler under my laptop. My celcius degrees are between 52C-55C when internet browsing w/ Chrome. I also use IDE's such as Visual Studio 2015 and Eclipse. When I start to load CPU, It reaches a maximum temperature of 81C without the Zalman cooler.

 

Generally (at the 52C-55C arounds) CPU fan works 6-7 second and stops for a 3-4 seconds, and loops like that. (Room temps are 21C-24C)

Btw, I am checking CPU core #2 by using Open Hardware Monitor. Unfortunately, it only shows core temps, not package.

 

Performance is not so bad while compared to itself. Maybe %10-20 percent lower. CPU-Z measured 2100 points at 2666 MHz (My GHz is actually 2.8).

 

I know I should but, I didn't change the thermal paste since I bought. This laptop was gone to the technical service a lot of times but, only of 2 times they cleaned the fan. I don't know if the tech guy change the thermal paste but, I don't think so.

 

Here is my main question: I am thinking of delidding my aged CPU while changing it's thermal paste. I thought like, If we change the thermal paste over the CPU, we should change the inside of it, too. It should harden too in time and lose its ability to conduct heat. Delid is a risky move and I don't know if I should. I just wanted to ask you. I watched Linus' delidding video and asked myself, if there is thermal paste inside CPU, too; should we clean it and reinstall thermal paste? (I am going to apply not the cheapest but the price/performance efficient thermal compund) If I shouldn't delid, should I delid it when it is 10-12 years old?

 

I like using things in long terms. I am happy if the products that I bought lasts long.

 

Am I torturing my computer?

 

Thanks.

laptop cpu's often don't have a lid. i don't think this one has either.

You can't delid laptop CPU

I recently de-lidded a 6700k using the Rockit 88 tool. I think Linus was sent one in a recent-ish mailroom video but I'm not aware if he's ever used it.

 

I suspected my sample was below average in IHS TIM application and the hottest core dropped 9C (Prime95 small FFT equivalent load) after normalising for ambient, by replacing the inner compound with Noctua paste. In reading around, the paste used by Intel is not chosen for best performance, but for long term stability. So ageing shouldn't be a problem for it in a reasonable lifespan.

 

BTW if the laptop CPUs don't have a lid, that'll make things a lot easier

Thank you all.
