Thermal paste problems :(

Do you know how to apply thermal paste ? I tried doing it but I ended up increasing my temperatures );
Now idle temp is 70c , max is 100c over I used expensive artic silver 5 ($22)

First attempt it increased from 48c to 61c .
Second attempt , I added more thermal paste on top , temperatures raised to 71c .
All the temperatures are idle temperatures

Before first attempt I scraped off the oem thermal paste and used vinegar to cleanse it. Then I applied a small bit of thermal paste and spreaded it with my finger and pressed it down to push out trapped air.Second attempt was with the same steps but no cleaning , just adding on top of the first attempt thermal paste.

Thermal paste should be applied in very thin layers - the purpose is to fill imperfections in the chip and heatsink. The paste in itself is a bad heat conductor. Also you shouldn't use your finger as that will cause skin fats and possibly skin particles to be embedded in the paste causing higher thermal resistance. A toothpick, spatula, credit card or something like that works well for spreading (depending on the viscosity of the paste).

To clean old paste I use isopropyl alcohol but vodka or acetone should be fine. For some pastes water works well too.

 

Sorry to be blunt, but youre applying the past completely wrong. There are many threads on this forum with videos explaining the proper techniques and on Youtube as well.

You want to ensure that both contact points (GPU/CPU and heatsink) are clean as can be. High % isopropyl alcohol

You only want to use the bare minimum of paste necessary

Certain GPU/CPU heatsinks have their screws labeled with numbers to let you know the order to unscrew/screw back in.

You want to make sure you have cleaned off accumulated dust from the part of the heatsink that has the fan blowing on it.

Basically, either go to the specific subforum for your computer brand/model and post there for specific tips, or watch some video guides on how to do it properly.

Good luck.

You want to avoid introducing any foreign particles as much as possible (ie don't ever use your finger, paper towels, toilet tissue, or anything that leaves residue/particles in any part of the process)

 

Before we can address the thermal paste problem what kinda laptop are you referring to about that would give us a better idea where your coming from as that problem can be a varied problem in itself as it doesn't lend to know what is causing the over heating problem.
