Troubleshoot How often must we replace Thermal Paste?

[Purshu_Pro]

Briefly explain your current issue(s)

Now its cool and around 50'c . But sometimes it exceeds 70'c

Steps taken to resolve, but have been unsuccessful

Cleaned my CPU Fan 3 weeks back to fix it.

Hi Friends, I experience sometimes a lot of heat from my laptop. I get around 80 'c sometimes. So could this be a problem of my heatsink thermal paste? If so should i replace it? Which would be a perfect Paste as there are many vendors out there.
All suggestions are welcomed.

I bought it with new cpu. First day is ok and after 7 days i got 140 C. And 9 day i got critical 250 C

Well It was before the application of the Paste. Now its running under 40-60. I guess it could work only that much.

That's a lot. Quit impressive them other thermal paste i use.

You applied excess TIM, happened to me while applying for first time.

Arctic silver is not the problem, i guess.

Did u properly clean the old thermal paste leftover with 99% isopropyl alcohol before u applied arctic silver 5? Also did u applied properly ' pea size' ? and wut thermal paste u use after that?

Yes, of course.

I now using Prolimatech PRO-PK3-1.5G

Did you use the pea method for applying TIM? AS5 is the best in the market and did you know that AS5 needs a burn-in time of 200hrs for best results. I'm using AS ceramique 2 which is very good, decreased 5-10C on cpu & gpu.

That's not quite true, currently the best on the market is Coollaboratory Liquid Pro/Ultra but since it's 100% metal based I will never recommend it to somebody who is not used to applying thermal paste.

 

[Vasudev]

Thanks. Never heard of it(my ignorance) metal based TIM could cause short circuits if applied incorrectly.

That's fine, the company is mostly selling it in Germany and yes that's why I almost never recommend it!

@Purshu_Pro : As @Enju mentioned try to check it, the replacement is very expensive if still persist which you don't want as an outcome. Many users posted on many forums regarding this problem and I think its just isolated case.

 

[Purshu_Pro]

Well friends I will try to re-assemble my laptop and check it. If it get fixed I will be happy , if not I will buy a LCD monitor !

 

[Purshu_Pro]

Well I am happy to say that I have fixed my screen issue by reconnecting the connector as @Enju stated and as @jamescv7 taught. But as the discussions made above, I'm not satisfied with Arctic Silver 5 TP. It takes my computer temperature to 80 again. My average temp is now 55-60
So @Koroke San what would u like to say about this?

 

[Koroke San]

@Purshu_Pro What is your current cpu idle & load temperature & what thermal paste you are using currently?

I think its normal temps(Mine idle's @55C), considering the fact, the room temp is greater than 27C in India right now, Where do you live? Mumbai or Delhi? Have you tried cleaning old paste with Q-tips and re-apply the paste with half of pea size? Also if possible, disable these service to check temp issue is solved:
1.Change startup type of all VMWare Services to manual, SQL writer service, Windows Phone Service(I can't remember the name of the service)
2. Have you compiled native Runtime after installing VS 2015 CE? Just compile it using, ngen eqi /nologo /silent for both x86 and x64 .net frameworks.

That is not bad at all.
