    This thread will serve as a guide for new comers to the forum and will possibly reduce the time reading through long never ending threads.

    TL.DR; This will guide in choosing the best thermal paste that suits you.

    Code:
    -----------------------------------------------------------------------------------------|
    Well Known Brands:
    
    Thermal Grizzly (aka TG)
    Coollaboratory   (aka CLL)                                                                                            
    Phobya
    Gelid
    Prolimatech
    IC Diamond
    Cooler Master
    Noctua
    -----------------------------------------------------------------------------------------|
    
    =====================================================
    Traditional:

    TG Kyronaut:
    12.5 W/mK
    Gelid Extreme: 8.5 W/mK
    Phobya NanoGrease Extreme: 16 W/mK [Thanks @Mr. Fox ]

    Liquid Metal:

    TG Conductonaut: 73W/mK
    Coollaboratory Ultra or Pro: 68W/mK
    =====================================================


    List of Thermal paste must be sticky post as @Papusan said.
    Post updated to included new Traditional Thermal Paste from Cooler Master.
    Traditional Paste: [No specific order]

    1. TG Kyronaut 12.5 W/mK
    2. Phobya NanoGrease Extreme 16 W/mK { Thanks to @Mr. Fox }
    3. Gelid Extreme 8.5 W/mK
    4. ICD 7: 4.5 W/mK
    5. Prolimatech PK3: 11.2 W/mK
    6. Cooler Master MasterGel Maker Nano: 11 W/mK [ Thanks @bloodhawk for confirming this]
    Liquid Metal Pastes:[No specific order]
    1. TG Conductonaut *: 73 W/mK
    2. Coollaboratory Ultra or Pro *: 68 W/mK [Thanks @Papusan ]
    3. Phobya LM *: 40 W/mK [Thanks @Papusan ]
    Sorry this is non exhaustive list.
    * indicates important notes whilst the use of metal paste.

    • Heat sink must be copper
    • The surface of heatsink and cpu/gpu must be clean to provide even contact because metal paste will fill the air gap like a thin film The surface have to be completely flat, and the contact between the heatsink and the die have to be PERFECT ( minimum gap between both) { credit to @judal57 for this}
    • Tape the outer die of CPU or GPU to avoid spillage due to over-application of paste
    • Use spatula paint brush or similar, to even out the paste on the die and apply remaining paste on the heat sink (Thanks to @Papusan)
    @Papusan @iunlock @judal57 @Mobius 1 @DeeX @rinneh
    @unclewebb @Mr. Fox @MahmoudDewy
    I hope this list can serve its purpose for new-comers to our forums deciding on which paste to use and why, instead of reading thousands of posts and it will save lot of headaches.
    EDIT: Sorted out the discrepancies.
    Updated with W/mK values as @sicily428 said.

    All well-known brands could be presented in a "separate section" of the OP post(Put in a spoiler). But the best one should be presented as it is now.

    I actually use a paintbrush for oil paintings. A bit on the expensive side but can be reused unlike the cotton bud included with conductonaut. Less chance of the fiber contaminating the LM too.

    I as well use paintbrush like what you do. You can find some very cheap as well who is much better than the cotton sticks from Grizzly. And in different softness.

    @Papusan: Does the OP look like what you meant? Or should I modify it further.

    Yeah, it should be put up cleaner. I'm on my phone and can't help set up suggestions for cleaner setup now. I can give you a suggestion later and then delete it afterwards with edit. But you are free to make it as you want.

    Could you put information about safe climates for using LM? Like whether you should worry about going outside with it for an extended period of time on days when it's below freezing.

    I've also seen one of those paint wedges (spongy texture) used, but I think I like a brush a little better.
