    Glad to see someone give it a shot.

    As I was putting my P370EM back together after reflowing a failed solder join on one of the heatpipes I tried the LM sandwich with the pad on both the CPU and slave GPU (not master GPU). Each already had shims and LM (and kapton/foam dam) in place.

    I ran a simple test just sitting there in the Crysis 3 jungle level, all Ultra 1080p with 100fps cap, aircooling only, GPUs at 115W each max 1950/0.95V

    With pad:
    CPU thermal throttle @ 99C (maintaining 3.7-3.9ghz), slave GPU thermal throttle @ 92C (maintaining ~1600mhz), master GPU in the 60s
    Throttlestop 1B: max 96C @ 4.2ghz (avg low 90s)

    Removed pad: CPU 92C max (constant 4.2ghz), slave GPU 82C (maintaining ~1750mhz), master GPU 60s
    Throttlestop 1B: max 88C @ 4.2ghz (avg mid 80s)

    fps didn't drop much so the thermal throttles weren't that bad. I think due to the shims already there, no gain in gap filling or mounting pressure was there to be had

    Wow the pad made it a lot worse.

    Was that the Soft PGS pad, or the regular graphite pad? (seems to be proven that the IC pad is Soft PGS).

    You said you were using shims. How thick were those shims. If more than 0.2mm, them you left a gap. The other alternative is it was light contact/low pressure. That decreases performance of the PGS, which effects everything else. You should mention those aspects because without them, you are missing key bits of information that allow drawing proper conclusions for this information.

    Mind you, this is compared with a setup I've spent a lot of time trialling & erroring as it's basically using 115W GPUs on 75W heatsinks without the water flowing.


    Calipers read ~0.2mm thick (but tbh I don't really trust them at such small distances). Seems rather compressible by squeezing them on a small offcut I was able to get the calipers to read 0.0mm

    0.5mm shims, it's a fell-apart-and-rebuilt fused CPU and slave GPU heatsink with a copper pipe for carrying liquid and "learning experience" level workmanship, it needed shims to have any contact in the first place... but once that contact issue was sorted the water cooling setup kept both GPUs at ~70C (~35C dT) under 200W stress test load.

    The value of my simple comparison is that there is no automatic benefit to using them as a shim.

    The one thing I didn't mention is that Core 1 was still the hottest on the CPU by 4-5C just as it is with liquid metal - the implication there is a concave CPU HS that would benefit from lapping - which I would do if I could find my ^!@#$)& pile of fine sandpapers going up to 5000grit




    Out of interest heres a macro photo of what it looked like afterwards. After I took the GPU one off, it was interesting that some of the LM did choose to stick to the pad... I put it back in its plastic sheath which is what it's pressed up against (without any pressure applied)

    Surprisingly good! lol.. literally took no time, well maybe cutting out a template for the CPU and GPU took me a little bit but after I slapped it on there, mounted it and I was back online. Max temps a little lower and consistent than the TGK I had on there. Overall satisfied.

    Installed on a GT73VR:
    6820HK @4.0GHz
    GTX1070 @2GHz

    Installation time: aside from cutting out a template, didn't take more than 15 minutes.

    Only thing is waiting for it to go back on stock on Amazon as I'm not a tester and had to buy it and I live overseas so +a week to shipping.

    Did you coat the GPU resistors with nail polish first? That was EXTREMELY dangerous! That pad would glide across my r9 290X out of place if I even so much as stared at it too long. Like NO traction at all. If that pad shifted and touched those resistors, your GPU would be gone.

    nope, even though I did a quick job, im not that careless lol.. ive worked with conductive paste and with computers for a very long time so i know what im doing :)

    I put the pad on there and the heatsink and kept pressure on it then mounted it evenly. I hand tightened the screws till there was no more turn. I guess I can see it when people say there wouldnt be enough pressure but at least for me I'm lucky to have an decent cooler.

    As far as temps goes its looking pretty nice, woke up this morning idling at a nice 34C on CPU, 55-60C playing games (only at 4GHz tho). Stress test it was capping around 75C (fans AUTO)

    GPU also around the same 60ishC on load. (fans AUTO)

    I would probably say this goes about 2-3C above higher quality paste, but as far as installation goes and longevity (not having to worry about it) then the pros out weigh the con. Unless that 2-3C was preventing you from going further with your overclock.

    But as with everything YMMV, it is highly conductive so install at your own risk.

    I Just want other people to be careful. Because when I tried installing the pad on a 290X, any tiny vibration of anything would make the pad move when trying to attach the PCB to the heatsink. I was in no danger since I have nail polish insulting everything. But a random person could easily kill his card.
