    I was inspired by this tutorial and I did the same liquid metal repaste, noticed a 10 degree drop in temps for both CPU and GPU under load. It's great, but with that headroom I would like to overclock above the possible 135 mHz, can you explain how you got the vbios modded? Appreciate it

    Edit : If someone has original vBIOS or a vBIOS that works for 2016 970m can they please forward it to me?

    Hi Everyone, I have an old 2014 Razer Blade with the 870M GPU. I'm really considering trying the LM method but was wondering if I am buying the right supplies needed. Can anyone double check these are the right ones? Thanks

    Is it possible to get extra security to avoid LM on aluminum by using both the JB Weld and putty together on the copper?

    That seems really excessive.
    You need to remember that the width of space between the BGA silicon slug and the BGA housing is less than 1mm. Both of those things you listed I can't possibly forsee them being less than 1mm in compression.

    For basic protection of the SMD /exposed traces and resistors around the CPU and GPU housings (assuming you're doing the GPU), you can use Super 33+ tape, Kapton tape (not low quality tape), or 3 coats of nail polish (Cellulose based). Don't use regular old cheap electrical tape. That stuff is bad and too thick. You can use Super 33+ or nail polish. I personally use nail polish but it's your choice.

    If you're talking about "emergency dams" to stop LM runoff, then there are several ways to get creative.
    You can use VERY VERY lightly dense cutout compressible foam, with a shape cut out in the CPU or GPU, but it has to be VERY light foam. Dense foam isn't good because it creates resistance on already super light pressure heatsink mountings. If you find foam that is like 1/4" of an inch thick, and compresses EASILY to the width of a human hair, in your fingers, without resistance, you can use that. You can also cut out a square of it and if you have a very fine exacto knife, 3M blade or other titanium blade, you can try cutting it in half to make the thickness even less (but this is very difficult to do without destroying the foam), but its doable.

    Another thing you can try is to use RTV silicone, a VERY thin layer of it in a circle around the housing, and then compress it with 3M Super 33+ tape. It has to be a VERY thin layer, remember what I told you about the BGA chip silicon being less than 1mm raised up? Then after you apply your layer, do the 3M tape insulation and make sure you compress it well so there is far less than 1mm of any raised surface. Then apply your LM and mount. Later, when you remove the 3M tape, you will see the RTV silicon has hardened. If you did this right, the layer should be firmly around the CPU, without blocking the heatsink, because the heatsink compression should keep it down. Then you should have a permanent dam, and you can remove the 3M tape and apply nail polish instead later. Mr Fox tried something like this, although I haven't.

    Another option is to use a very thick thermal compound, not the stuff you usually buy now, but the super thick white stuff that used to be common in the past, like Radio Shack thermal compound, or Ceramique or Ceramique 2, and apply that in a circle around the edge of the CPU or GPU area. Just be careful and don't apply a lot and make sure you don't get it on the chip itself. that will also act as a barrier and that old stuff is so thick that it won't go anywhere. It may dry out but it will still be there.

    The RB has a direct to heat pipe contact with aluminum plate, so the OP used epoxy diluted to protect the aluminum and Mobius used RTV silicone.

    The RB with the 870M has the direct to heatpipe on the cpu and gpu.....so the RTV silicone or epoxy should be used on both sides....this is mobius method with RTV.

    Do NOT use JB weld

    RTV silicone is more than enough

    Great, Thanks for the quick replies. I'll try the RTV silicone and Super 33+ to see how it goes.

    Can I mix the rubbing alcohol with the RTV silicone for an even layer?

    Just wanted to write my experience without having to open up a new thread.

    I've yesterday repasted my 2017 Blade, which was reaching 100C CPU wise during PUBG sessions at stock. The repaste was done with the only thermal paste I had available, a MX-2.

    Temperatures dropped like CRAZY; I've tried running prime95+Fire Strike all togethere and CPU has never gone over 79 C at absolutely all. I've had few hours long PUBG session on an external 144 hz monitor and temperatures stood under 78C, peaks included, while GPU reached 80C.

    Razer thermal paste is ****, I've had 3 Blades and I've gone through 7 RMAs till now in around two years and this is the only repaste I've attempted and I absolutely regret having never done it earlier.

    I'll buy diamod paste whenever I get the time to do the work and will attempt to go even lower with temps.

    Wow, that's pretty hot for the cpu. Even before repaste I would have looked at solutions like throttlestop and disabling turbo and hyper threading. Even with repaste I suggest you look into those as well. From what I found on my 6700HQ, doing any of the above does not impact performance much. In fact, because of the lower temps of the cpu, you can push your graphics higher I.e. over clock for bigger performance impact. I was regretting buying 970m model when 1060 came out like 2 months later but doing this made it worth it.
