    New Heatsink and fan, should I wipe the already applied thermal paste?


    I ordered a new heatsink and fan that I've received already , checking the new Heatsink and Fan, I've noticed there are two layers of sticky material ( I assume that it's the thermal paste). The first one is a bit bigger material that is on the heatsink part where it's going over the CPU, the other sticky material that is on the part going to cover the Graphic chip I guess..
    so what about the two sticky material that I've seen in the heat sink, are they the thermal paste that the seller has told me about ....

    should I wipe the thermal paste in the heat sink and put the Arctic silver one instead after cleaning the CPU and chip by using ISOPROPYL ALCOHOL , and do I need to tint my heat sink....
    ....

    I would use the Artic. as far as tinting I don't know.

    the problem is that I've just contacted the seller and he told me that he is highly not recommending wiping the thermal paste on the new heatsink and whatever i do it'll be under my responsibilities , even he told me the Arctic silver is creating problem and CPU stops working on many occasions he's seen
    he' just advised me to clean the CPU and graphic Chip using the highly concentrated alcoholic liquid , and then put the heat sink without touching the thermal paste already applied on the heatsink
    I got confused and i do not like to do something that might void the warranty of the newly heatsink and fan , and in the other hand I want to do a good job that will increase the efficiency of my Laptop , and reduce the overheating and I do not really want to re-open my Laptop to apply new thermal paste as assembling the laptop is not easy at all ....

    theoretically you should clean the chips and apply the heatsink without removing what is already applied to it.

    If you want to go and adventure (and likely to void the warranty) remove them and apply a better thermal paste, make sure that it is NOT CONDUCTIVE and NOT CAPACITIVE (must be clearly stated somewhere, anything else goes in the trash). So that any spill won't short-circuit or otherwise interfere if it goes on the board or wherever. So you can just put a small blob and forget about it looking messy.

    In any case, don't mix the pre-applied with the new one.

    What you are saying is the new heatsink has pre-applied thermal paste? I'd leave that on there. I would, however, take 90%+ Isopropyl Alcohol and a coffee filter and clean the CPU really good before installing the new part.

    As mentioned, you're choice op. but as KB said, at least clean the CPU.

    Since its a laptop cooler, just stick with the pre applied paste.

    Thanks guys, I've done what you told me. i cleaned the CPU and installed the HSF with the pre-applied thermal paste
    now the temperature is getting lower and in the range of 40 C

    Good to hear! Over the next day or so you might see it drop a few more degrees as the paste "settles" in.

    Perfect :)


    My laptop with IC Diamond and fan sits around there. You're in the zone.
