    I actually use the same heatsink as you on my master gpu. I upgraded my EM heatsinks to SM-A heatsinks while back. I did add more fins to cover the whole fan lenght and taped all gaps. Used autofans instead of max.

    So you chopped some off and used a thermal paste between them then? Or soldered them?

    So why the switch to this cooler?

    I used thermal adhesive. There was some foam to fill the gap.
    I bought SM-A heatsiks for better slave GPU cooling. Didn't see any difference in master tho. Some have reported cooler temps than old EM 2-piece heatsink.

    Temps with max fans
    CPU: 75*C
    GPU: 79*C

    I've generally read the opposite on the heatsinks with the split design being less efficient.

    I suspect my GTX 870M is dying after using the laptop for 4 years and a bit. It started with the screen freezing when I was playing games (BSOD error: VIDEO SCHEDULER INTERNAL ERROR), and now the whole Windows freezes just a few seconds after booting up. Tried reinstalling the Windows (both Windows 7 and Windows 10), but still can't solve the problems. And if I go into the safe mode, it works perfectly fine.

    Besides, it can detect my GTX 870M in BIOS. But in Windows, it only shows my iGPU in Device Manager.

    So I guess it's either the graphic card or the MXM port of the motherboard? I also tried to boot up without the graphic card. The fan for the graphic card was spinning on full speed, the laptop kept beeping and eventually it shut down automatically around 10 seconds later. Is this because the EC can't detect the graphic card? And is there a way to stop this?

    I just wanna make sure it's my GTX 870M causing the issues before I pay a few hundred bucks to get a new card.

    Thanks in advance.

    It's hard to say for 100% but it's rarely the slot and the shutdown is because the ECU gets no signal from the GPU when it's removed.

    You may want to play with your heatsink fit to see if you can make it perfect.

    I've ordered some Thermal Grizzly Kryonaut to test with next. It's got 12.5 W/m.K, whereas the MX4 has around 8.5.
    So it should help.

    It's a good paste, check your spread pattern when removing the heatsink, share a pic if you can.

    Tried same oc and scores were same. Temperature reached 79°C with GC-Extreme and max fan. Do you have max fan feature?
    New paste will help a lot.

    I dont have the max fan feature. But it sounds like a jet engine anyways

    I did replace the thermal paste already about a month and a half ago, since even the CPU was thermal throttling when I bought it.

    It turns out it's the GTX870M having issues. I've got a GTX1060 running in it now.

    Indeed. Runs cooler, but much better performance.

    Used to get 50ish fps in GTA V with mid-high settings. Now with everything maxed out, I still get around 60fps most of the time.

    Small major update on my thermals ;)

    Did a number of tests in stock configuration.

    I made screenshots of Idle temperatures, after running the Furmark Benchmark and 3DMark, as well as CPU-ID CPU Bench.

    After these baseline tests, I began tearing down the laptop to clean off the MX4 and apply some fresh Kryonaut.

    Between applying the MX4 and buying the Kryonaut, I learnt that with direct die contact it's a better choice to spread the paste, rather than applying 'a grain of rice'.
    Wether or not this is true, I dont know, but this time I decided to spread the paste, as directed by Thermal Grizzly.

    As can be seen on the CPU, the grain of cooked rice method did give me a consistent and even spread of the compound. The MX4 was also still very 'fresh'.

    On the GPU, on the other hand, it was clear that some portion of the die did not get as much coverage as the other, or was spread out much thinner. (the lightly coated areas on the die and heatsink corresponded) The MX4 also dried out a lot more. This might have caused some higher and uneven temperatures across the die.

    The thermal Grizzly Kryonaut was applied and spread out evenly across both the CPU and GPU die this time around. And I paid close attention to apply the heatsinks nice and evenly. [​IMG] [​IMG] [​IMG] [​IMG] [​IMG] [​IMG]

    After this, I ran the same barrage of tests, to see wether or not it had helped… This time I did not take a printscreen of the CPU test, since it wasnt a very good test to begin with, I should have logged core per core temperatures. All I have is the stresstest, which bumps up the temperature untill it throttles anyways.

    Here is a comparison between the 2 Afterburner Logs, I would have liked to plot the GPU-Z ones in excell, but that thing freaks out with datasets over 255 points...

    Anyways, You can clearly see, while running the same benchmark, that the Thermal Limit sets in way later now with the Kryonaut (on the right), while it manages to maintain higher clocks as well (759Mhz compared to 696Mhz before)

    The comparison? It was a 5 minute FurMark 1080p benchmark.
    You can see it hittin the power limit untill it hits the thermal limit. It's a pretty taxing benchmark.
    So it will always ramp up till thermal throttling under that kind of load.

    Just be careful running furmark over and over, it's generally not recommended for notebook vrms.

    Pretty standard behaviour for a furmark run from what I see, the drivers do detect the load and limit the card beyond normal limits so it's a bit hard to use for testing too.

    As seen on pictures you haven't sealed the gaps between the fan and heatsink? Try doing that with some foil tape.

    Ah, yes I could try that, but I'm pretty happy with the thermals as they sit right now. Theres a bit of hard plastic running from the heatsink till the top port of the fan tho.

    You can do top and sides without removing anything. Just next time when you repaste make sure you remove the heatsink with the fan as one single piece to tape the bottom.

    Its not that I m bad at it or dislike doing it, just the Kryonaut is pretty costly

    But it was the first time I ever spread it out like that and the Kryonaut applicator is pretty bad to use, wish they would supply a spatula as well

    By the way, besides the Furmark I also ran 3DMark Firestrike to compare data.

    With the MSI Afterburner logging everything in a bespoke log viewer, I found out:
    - in general I dropped 2-3 degrees C on my peak GPU temperatures during the same scenes (with a small increas in core clock of about 10-50Mhz)
    -whereas my CPU dropped between 5 to 10 degrees C during the same scenes!!!

    Amazing stuff this Kryonaut!

    hi guys I plan to upgrade to windows 10 on my P157SM,
    what problems will I have with the drivers ?

    or is it better to stay under windows 7 with no problems ?^^

    I have been using Windows 10 for 2 years now. No issue at all.

    I am still using the drivers I have for Windows 7.

    The keyboard lights stop working, the screen sometimes dims automaticly to full dim. Other than that no major issues.

    The LEDs have their own cable coming from the keyboard, check that's in on the motherboard.

    Hello All,
    I was hoping for some help clarifying GPU upgrade paths. I would like to upgrade to a 1070 but I'm confused with some things.
    I see there are 2 versions of the 1070 card that are around: the MSI and the Gecube/(Eurocom?)
    Are revisions of these GPU's that I should be aware will or will not work?
    Are there specific GPU BIOS that is necessary to install for these to work? mobo BIOS
    Is it true that the Gecube version is prone to blowing up?
    Can the modifications be done in place to the current heatsink?

    I'm ok with purchasing a used card pulled from another machine just so it will last for another 6 months or so until the 2070 mobility lines are released so I'm not too picky about getting a pristine new card.
    Thanks in advance!

    Most cards are the wrong shape so you need one of those two. No bios required iirc. The gecube had a much weaker vrm.

    The MSI card might need you to cut some bits in the heatsink iirc which would be the downside to that.
