    Hi,


    I would like to have your opinion about interest of Grizzly Kryonnaut repast on Razer 15 2018.
    I apply a -160mv cpu igp UV and my temp decrease of 10c!!

    No Repast No UV (ambiant temp 28c (France))

    It's a good score I mean.

    If i repast CPU/GPU by Kryonnaut Grizzly how many can I gain?
    Is it interesting to change pads by Gelid one 14W/mk?

    Thanks in advance.

    Best regards

    You might see further drop in temps by 5-10C max. With repads you can decrease temps by another 5C (max). Overall you'll be happy.
    So what's the temps when you're gaming for sustained periods of time? Example: Witcher 3, PUBG,GTA 5 etc..

    not to hijack but pads will decrease temps by up to 5C?

    Yeah it will. I simply quoted a low number of 5C. I managed to decrease 10C(See system specs as a spoiler in my signature). So, for some people you'll see 10-15C reduction if stock pads didn't touch the heat sensitive parts correctly. For some people they see no difference or 1-2C drop. Experiences will vary acc. to ambient temps and other environmental variables.

    I do a repast with Kryonnaut.
    My first try i made a very a thin uniform layer on cpu and GPU : 6c increase!!! :mad::eek:
    At the second try i made a thick layer on cpu & gpu : 2c gain
    I just replace de thermal pad on the PCh by Gelid 14W/mk one...

    I wonder if the pads are not too thick because they are really very crushed and decrease the pressure on CPU/GPU...

    What is your opinion on this?

    I played 30min session of Serious Sam 3 in ultra mode and I selected processor option to ULTRA (I don't know what is this option) : Result : 97/98/97/99/100/98 :eek::eek::eek:
    Without processor ultra : 92/91/91/93/92/91

    You can see pads having deeper grooves or imprint on some pads and while some don't have a imprint at all. From the looks of it, try lower W/mK gelid pads and stack them over existing pads with improper contact. Try with 0.5mm first, I think it should work.
    If you have higher ambient temps, you can use lower W/mK gelid or even arctic pads.
    I feel the paste was excessively used. Kryonaut was a white paste IIRC, I see gray paste just like IC Diamond or maker gel.
    Remove the rubber applicator and put a small pea in the middle, afterwards use the rubber applicator to spread evenly in one direction to get smooth finish. If the paste isn't enough use the same amount once again. On GPU use a big pea and spread it the same way like cpu. Hopefully, your core temps should decrease by 10C.
    @Papusan Is it safe to lap the vapor chamber on heatsink?

    Graphite pads are not good.

    why?
    I would try only on CPU/GPU not in replacment of pads.
