HP Omen stock thermal paste

[Micpb]

Hello everyone

so after almost a year my warranty is coming to an end and i was wondering if i should repaste my laptop

some people say stock thermal paste is usually of bad quality and slopply applied since the person doing it does hundreds laptops a day

other say the opposite, that factory paste is "perfectly applied" since they mastered that process there

some say they got -20 degrees after repasting, others only got a couple degrees or none at all

so i wanted to ask if anyone has experience repasting Omen 15 laptops after a year or so (if not, then when)? What did you find inside and was it worth doing? Please share

@Micpb Welcome to HP Community!

I understand that you would like to repaste the thermal.

HP will not recommend applying the thermal paste.

In that case, I would suggets you contact our phone support and check for the support option. They will help you.

Or you can contact the local service center for repair.

Here is how you can get in touch with phone support.

1)Click on this link - www.hp.com/contacthp/

2)Select the product type.

3)Enter the serial number of your device or select let HP detect your product option.

4)Select the country from the drop-down.

5)You should see the HP phone support number or Chat option listed.

Always start with a simple rule that separates urban myths or lies from honest science.  The informed recommendation will always say by and cite relevant parameters.  For example, what is the thermal conductivity of a thremal compound that you are considering?  Most all heat transfers in a direct 'semiconductor to heatsink' conctact.    Those numbers are typicaly tens of times more conductive than thermal compound.

Heatsinks are tapered so that most pressure is where all heat is generated.  In the center millimeters areas where the silicon die resides.  Only the informed know this.  And know why that heatsink is tapered.  To even squeeze out all thermal compound except what is in microscopic air gaps.  

Thermal compound is more conductive than air.  Thermal compound is significantly less conductive than direct contact.  So thermal compound is only reducing semiconductor temperatures by a few degrees - if that heatsink, has no defects, is properly machines, and is properly mounted.

Thermal compound is only about reducing temperatures by a few degrees.  A chain of thermal conductors from silicon die to ambient air is about reducing temperatures by tens of degrees.  But that does not sell inferior or similar thermal compounds to naive consumers - who even recommend replacing it every two years.

Thermal compound even fifty years ago did not go bad even 20 years later.  Conductivity must remains constant for decades.  That is why we do not use mayonnaise.  

More numbers?  A company that has been doing this ever fifty years ago demenstrators how thermal resistance varies with years:  https://encrypted-tbn0.gstatic.com/images?q=tbn%3AANd9GcR5lcJqwPT0oPsG4ZatVoJTqK_MImfLmZkrsg&usqp=CA...

It does not vary because thermal compound (unlike mayonnaise) does not degrade.
