Few questions before REPASTE?

Guys I have finally decided to go for a repaste job because of too high temps.
So I have few last questions.

1. Which paste to go for. - Artic Silver 5, Phobya Hegrease or Prolimatech PK3. ?

2. Whats the diff between conducive and non conducive paste.? ( As far i can get to know that non-conducive are safer to use coz even if you overspread or over apply them , its safe). if thats the case then which of the above is better non conducive paste. AS5 is conducive I knw but what the other two.

3. How to apply and how much to use. ?
4. Do I need anythung else to change or put new while repasting. What about thermal pads. I dnt knw a about this. ?
Please help guys.


Thanks

 

1. None of the above, IC Diamond. If you can't get that then Arctic Silver 5 is usually available everywhere.

2. Arctic Silver is NOT CONDUCTIVE. It is slightly CAPACITIVE. They are two completely different things. Conductive is terrible for thermal paste, you want them to conduct heat, not electricity. All capacitive means is that Arctic Silver 5 can bridge circuits if not applied correctly, if you are careful and make sure the paste only goes on the CPU/GPU then you will be fine.

3. CPU is rectangle shape so about a grain of rice, GPU is square so a round blob roughly the size of a pea. If you think its too little, its probably enough. Putting too much on defeats the purpose, what you are doing is trying to make a solid even connection between the CPU and the heatsink, because the surface of the CPU and heatsink are rough (even if they don't feel rough, they are.) Too much paste will actually lock the heat and and cause more problems.

4. Everything else should be right, make sure the thermal pads look fine, you shouldn't need to replace them if they look fine. Do a general inspection while you have it apart and blow the fans out with some compressed air.

 

Thanks bro.... but while googling I found the results of Prolimatech and Phoyba Hegrease better than Artic Silver 5,
Can u suggest any non conductive ,non capacitive paste so that even I mess up putting too much I dnt short my MOBO. Like Artic MX4,

Thanks for the reply bro....u answered my all doubts

 

Digitalmo made a good thread about this topic, read it here.

 

The thing is that one or two reviews might say its better, but Arctic Silver 5 has been around for years and its tried and true, I myself have used it countless times on my own rig and my friends and family's laptops and desktops and I trust it. IC Diamond is the best for cooling that I have seen but its relatively new, and I have heard reports of it scratching the tops off CPU's and GPU's because its diamond based.

If Arctic Silver 5 is what you have, by all means use it. All it being capacitive means is that you have to be careful that it only goes on the chip and not on the mobo - unless you are a complete numpty this shouldn't be a problem there is no risk of shorting anything out otherwise. Even if you do mess up, just clean the paste off. Take your time and don't rush, set aside an afternoon to chuck it on. Just keep in mind that some thermal pastes have curing time too - AS5 is particularly brutal in that respect, it needs 50-200 hours before you will see the full temp drop. Some pastes have 2-5 hours, some have none at all.

 

Thanks guys.... I am able to get both IC Diamond 7 carat and Artic silver 5 through ebay. luckily It is available for India.
Anyone can confirm problems with Ic diamond scratching the CPU and GPU

 

IC Diamond warning

Although its only really a problem if you change the paste all the time. Otherwise its only a few scratches here and there.

Depends on if you need the absolute best cooling solution, because IC Diamond is also thick and kind of hard to apply... AS5 is rather easy to apply and therefore get a thin even layer.

 

Thanks a lot bro.....!!! Appreciate the help...!!!! I will post my results after I do a repaste...

 

I also have a few questions.

1. Is dynex thermal compound alright to use? I just bought a tube from bb.
2. Also to clean away the old thermal paste, is it okay to use isopropyl alcohol 50% and a cotton ball/q-tip, or should I be using denatured alcohol?

thanks

 

1. Its probably ok on stock clocks I would have got something better myself personally

2. Isopropyl is fine, put some on a q-tip and swirl it around, then use cotton wool to get any leftovers.

 

I have sworn by arctic silver 5 for years, but the only reason I dont use IC Diamond is I still have a tube of arctic silver left and I was raised not to waste.

 

i have pasted new systems and re-pasted used systems to the point of losing track of how many brands and actual systems i have done.

one thing is certain you will be hard pressed to find more than a few deg difference between the crappiest generic stuff you can find vs the most expensive stuff you can buy. IMO the most important thing is application.

personally I use AS5 (Artic Silver 5)on my air cooled systems and AC (Artic Céramique) on my water cooled systems. main reason is when bought in bulk packaging they aren't that expensive & they seem to do a good job over the long term with out any weird application rules. some will say that AS5 needs to be "broke in" but i have never seen a measurable difference between day one and years later that can be measured beyond what would be considered margin for sensor tolerances. at least for systems that spend a lot of time over 50c. (which is why i only use it on air cooled systems)

ive used the Dynex stuff before too when i couldn't wait for shipping of "better" stuff. i never had and issues with it and it was just as easy to use and clean up as AS5 IMO.

 

ok thanks for the reply.. I was starting to dissemble the laptop and then when I was unscrewing one of the screws to get to the ram it stripped... now im screwed. Don't know what to do.

I was hitting 98 degress when playing Leagues(terrible)... so I just dusted it really good and im only getting up to 87ish. I still think I shouldnt be hitting those temps when playing that game.
