Laptop temperature increased after cleaning and replacing thermal paste?

Hello. I decided to clean my laptop and the thermal paste last month because it was almost 2 years since my laptop was cleaned (by service center folks in 2014).

I opened my laptop, cleaned every bit of it. The fan heatsink was full of black dust. I cleaned it including the fan.

I replaced the thermal paste on the CPU and the thermal pad with this thermal paste - http://ecx.images-amazon.com/images/I/61ZGzgbhkvL._SL1200_.jpg
(Cooler master V1 IC thermal paste)

Before I cleaned my laptop, Min temp. was 48 C and max temp was 66 C

Now after replacing the thermal compound the min temp is 51 C and max is 73 C

What is wrong? I used the poo method - http://dbclipart.com/wp-content/uploads/2016/05/Poop-cartoon-poo-clipart.jpeg

And the laptop temperature increases significantly when I play 1080p videos.

Please anyone can suggest anything? Is the thermal paste bad? Or replacing the thermal pad on the GPU with the thermal paste a bad choice?

  1. Looks like all the thermal paste has got concentrated at the centre of the CPU's heat spreader and hasnt covered the entire surface of it.
  2. did you in fact remove the thermal pad?if you did check to make sure the heatsink is securely attached and the fan is running.
  3. Yeah, if the temps were in the range you state, then messing with the CPU cooler at all was a bad choice. How did you remove the thermal pad? How much thermal compound did you use? That poop picture is useless, btw.

    I used Q tips dipped in rubbing alcohol (99%). The thermal pad easily came off.
    And yes the heat sink is attached as it was before with 4 spring screws. The fan is running too.

    I used almost 4 cubic mm of thermal paste on each.

    Okay, finally I figured it out. After the temperature increased, I ordered Arctic MX-4 Thermal Compound - http://ecx.images-amazon.com/images/I/519SY4zgtzL._SL1200_.jpg Decided to give it another go.

    Again disassembled my laptop, removed the heatsink and cleaned the previous thermal paste (Cooler master V1 IC) with 99% isopropyl alcohol and applied the new MX-4. Cleaned the thermal paste I applied on the GPU and applied a new silicon thermal pad on it (originally silicon pad was used). Assembled it.

    Now I get minimum temp of 38 C and maximum 60 C under 100% load.

    The Cooler master V1 IC was the culprit. It was a cheap paste and quality was bad too. Bought MX-4 from people's recommendation on tomshardware. Thanks.

    Just to summarize -

    Original state -
    Old thermal paste on CPU
    Old silicon thermal pad on GPU
    Full of dust and dirt
    Min temp - 48 C
    Max temp - 66 C

    After 1st cleaning -
    Cooler master V1 IC thermal paste on CPU
    Cooler master V1 IC thermal paste + a copper shin on GPU
    No dust or dirt
    Min temp - 51 C
    Max temp - 73 C

    After 2nd cleaning -
    Arctic MX-4 thermal paste on CPU
    New silicon thermal pad on GPU
    No dust or dirt
    Min temp - 38 C
    Max temp - 60 C
