Repasting GPU and CPU

Guys,

Last week, the technician replaced my CPU and GPU due to wrong parts that comes with my R3. I was busy at home doing chores while the technician was installing the parts. So I didn't really get the chance to watch everything.

I am worried because I dont think I saw him clean the old paste from the heat sinks before he put the paste and installed the sinks to the new CPU and GPU.
If let's say he didn't clean the old paste, is it going to have negative effect on maintaining a low temp on the CPU and GPU?
I had some minor CPU temp issues recently with my CPU maxing out at 89C for playing Tera MMO. During that time, my laptop lays flat on the table.
Is it easy to repaste them on my own? I haven't done anything like that but I can follow some good instructions.
Will the technician even install a new CPU/GPU without even cleaning the surfaces?

Sorry if I'm paranoid, its just that the technician originally called me on the last minute that day wanting to resched saying he wont make it because its almost 5pm. He later called again and decided he will do it and arrived about 530pm and he obviously looked in a hurry in doing everything. Didnt even install the GPU driver

 

Here is a guide on how to do it, its not that hard to do either if you follow instructions and take it slow.

it is ridiculously easy, just watch a video, and take your time be slow.. Slick's 7970m replacement guide is very very informative, shows you one by one removing all parts of GPU, also I would prefer first remove heatsink then GPU, much easier for me! The other is scary as you need a ton of force to remove from the socket with the heatsink installed

 

I guess I'll try this weekend. I actually did some practice already I dismantled my 5 yr old Quad Core HP desktop 2 days ago into its tiny bits. I repasted both GPU and CPU. CPU is not even anymore connected with its heat sink It felt easy because I really dont care if I will damage it or not because its an old PC

After that, it really look and perform new again. Before I cleaned them, you can grow some sweet potatoes on the heat sink of both GPU and CPU due to accumulated dust for 5 years lol!

Thanks guys!

 

anytime, feel free to ask if you have any questions.

 

^^^ JUST ANOTHER REASON WHY THIS FORUM IS THE BEST OF ITS KIND...THANKS YOU GUYS LIKE YOU AND I HONESTLY MEAN THAT.

Keep up the great work guys. Cheers

 

Thanks guys.
Another question. Are those tapes called thermal pads or thermal tapes? Do I need to replace them if I am going to repaste? Do I need to use the same tape for warranty purposes? If not, what exact brand do you recommend?

I hope to try repasting this weekend but didn't get to order the pads online. Are there some stores selling them?

 

they are thermal pads.I would just leave the stock pads on the heat sink as they do a pretty good job as is. I still got the same thermal pads on my heatsink that I had on it when I first got the laptop with my 460m and they are working great.

 

Nice. At least I can go on with the job this weekend. Thanks again!

 

oh man watch out for sweet potatoes I mean it is fun to play insides of a computer, I didn't do it for ages (desktop times) until I got this lappy, it is totally enjoyable and you can do experiments (some are costly though ) ahh the good old research spirit...

 

The dell heatsinks have thermal paste on the heatsink so all he did is put the card and the heatsink together and take out the other parts (together) and install the new stuff... therefore no need to clean anything off. No worries.

 

Are you thinking he replaced my old card with a new card that comes with a new heat sink? Its not the case for me, the tech used the existing heat sink. He just detached the old gpu and cpu from each heat sink and paste the new ones to it and its done.
I thought he should clean the heat sink contact to remove the dried paste before he repaste it to the new cpu & gpu for better heat transfer.

Every time I re-paste, I clean everything thoroughly using the Arctic Silver 5 (AS5) Paste and Articlean Cleaner Arctic Silver 5 (AS5) Paste and Articlean Cleaner: Amazon.co.uk: Computers & Accessories Cleaning the old paste is compulsory.

 

Yeah that's what I used on my desk top and that's what I thought too, cleaning for better contact and heat conductivity.
