I have noticed that when i play witcher 3 surface near the power button gets really hot. I checked temperature with PrecisionX Mobile software and it was 90+ degrees with fan speed ~4400 rpm. Then i bought a laptop pad and temperature dropped to 84-85 degrees. Laptop was not overclocked and is less than a month old, so it has no dust. Are those temperatures normal?  

which notebook model?

the model is sc17 1070 without gsync, also cpu temp is usually below 80.

the witcher 3 can be intense on the cpu and gpu.  you are running stock clocks, right?  Have you undervolted?  it can reduce the temperatures further.  Also for the GPU you can use a framerate limiter to like 59, so that your GPU doesn't get overworked as well, and the screen is limited to 60Hz anyways.

Might want to think about repasting your cpu and gpu also make sure your fans arent running at low rpm. I repasted and i didnt get amazing temps after but I never go above 90C any more

Why compound did you use ? why do you think you got worse result ? do you have a picture of the stock thermal paste ?

When i first got my SC17 4K G-Sync i was hitting around 95C-97C in Watch Dogs 2. So I first used Arctic Mx-4 and after I was getting low around 90C-93C temps. I then switched to Arctic Silver 5 where I saw a few degrees lower. I now see my temps getting mid to high 80C usually never going above 90c. Sorry I didnt document my changes but it definitely helped. I also found for me undervolting -100 and having my CPU clocked at 3.5 also help run it cooler and stable.

What do you think of repasting the laptop with liquid metal paste like Coollaboratory Liquid Ultra? 

Liquid metal is conductive, so if a tiny drop leaks out, it will fry the motherboard, and most likely warranty won't cover the repair.  If you don't have experience with LM, use Kryonaut, one of the best non conductive pastes available.
Have you undervolted your CPU on stock clocks, and still getting those high temperatures?  If so they certainly fixed the cooling on the 1080 model, since I am actually impressed with my temps with stock paste.

I have undervolted and my CPU stays about 10 deg cooler than GPU, guess i will repaste it.

Let us know how it goes.  I suggest changing the thermal pads as well, while you are it.  Something like Artic, but make sure to measure the original ones and use the same thickness on each area.

I want to repaste mine, eventhough the temps are fine, I would like it lower for overclocking, but the 1080 heatsink is different, can't find the screws on top.....so it means I need to remove the whole motherboard....bummer.  Eventually I will get to it.

 
vistarshook, if you do go ahead with the re-paste, would you mind taking a few pics along the way and share with us some of the steps? I'm not going to do that myself (temps look decent on my 1070), but may need to take it apart in the future to replace parts (fans/display panel) I've decided to keep mine instead of the 17R4, as I really need the 32GB RAM, as the equiv. Dell 17R4 becomes twice the cost of the SC17.

Thanks vistarshook! I remember reading that you wrote that earlier on the diff. The more I use this machine the more I really like it. The only game that stressed my SC17 was GTA 5 (haven't tried witcher 3, and probably wont, it's seems like it's too intensive on the cpu/gpu, I'll keep that for my desktop.) The max temp I got in 72F ambient was 76C on the CPU and 73C on the GPU (default fan speeds, didn't install the new bios with the precision tool yet after I installed Windows 8.1) Keep in mind, I set the max to 90% max on Windows for CPU performance and set it to prefer passive cooling and played the game at 1080P, not 4K. The only hot temp I got which is expected in idle is the PCH, mine idles between 47C (no active load) and 52C (very light load.) Odd thing is, one core tends to get 6-8 degrees higher than the other 3 when pushed with gaming, so I assume one possible issue is the paste/stamp wasn't set properly over that core. Anyways, the only games I play should be fine on this machine, esp. BF2 (consumes ~ 43 watts during game play,) Skyrim / Oblivion and GTA 5. Hoping to play Cyberpunk 2077 when it's released on it too.
 
KiddHazze, by any chance, did you take an pics during your re-paste process that you could post here? Also, on the 1070 fans, do you think they are custom or would a similar Dell (like from a 17R4) / HP ( like from an Omen) work if you need to replace them on a failure?

I would also like to see a guide or process to opening up and seeing benefits of repasting generally. As I am just college student who jumped on the 50% off deal on the SC17 1070G to finally get into PC gaming and am thus quite a novice when it comes to performance upgrades. I find tech very interesting and curious on how to optimize my investment.

alex.williams, to check for core differential, you need to run a program puts an even load, such as prime or occt, because in a game it might be stressing one core more than an another.  On my machine, the core differential is actually gone....I don't know, maybe the paste they used needed some curing time?  The PCH temps are actually really good, which is one of the issues on the AW R4, where PCH might reach in the 90s causing stuttering, since it has no cooling, some have done a heatsink mod for it.  About the fans, when I open my machine again, I will check for part numbers to see if they are generic and readily available or unique to the these models.

Great, thanks so much vistarshook, I really appreciate it! Looking at the photos on notebookcheck, there's no sticker/stamp info on the fans, it could be on the reverse or the side.
 
Thanks, that makes sense, looking at HWiNFO logging, the CPU cores were pegged around 98-100% evenly, which is why it stood out. I was wondering that myself too, I'm not sure if they used a stamp or something like AS. I kept mine on since I got, not putting it to sleep or hibernate assuming it was a stamp...I think with AS and similar products, from what I read somewhere they recommend shutting down for a few hours, keep on for a few hours, repeat a few times for curing, but I don't think that necessary for the standard stamped TIM? I have two 6850K builds at home and use Shadow Rock Slims for both using the paste I had left over from an recently refreshed SB 2600 cooler change using Cryorig's H7 TIM -- I just see the typical core variance of 1-2 degrees. Also to note, my PCH gets as high as 73C during gaming with GTA V, never seen it go higher....it actually could be lower once I register my laptop so I can download and install the precision tools to increase fan speed. I'm still on BIOS 1.01, will update to 1.03 soon (I don't want the meltdown / specter stuff yet, as I use VM's and taking a ~30% hit would be ridiculous. I'll wait it out until the patches get improved or stuff in wild is released to exploit it.

EVGA certainly stepped up their game with the 1080 model, with a much better heatsink. Also the chassis doesn't heat up as on the 1070 model.  Most high end gaming laptops with HK cpus and gtx1070/80 tend to have some thermal issues when pushed hard, requiring a repaste out of the box.  I was expecting the same with this model, but to my suprise it runs well out of the box with stock paste.  I still will do a Liquid Metal job eventually to see what it can do.

Very nice vistarshook! I just the got a CoolerMaster X Slim today, and it's helps with the PCH on idle (about 2-3C cooler on idle) but not the CPU/GPU on idle. But it does help the CPU/GPU when maxed out with GTA V, by about 5-8C -- max temp on GTA V on the GPU is now 68C rather 73C, CPU at 63C, but again, I'm limiting my CPU speed currently to 2.4GHz, but those temps at 4.0 are really impressive! I'm going to be at the Mall this weekend and I'm going to get some panty hose from Macy's this weekend (they have them for trying out women's shoes) to make a filter for the CM fan.
 
I have a MBP (from work) that's almost always pegged at 100C for the CPU and over 80 for the GPU running vmware with centos. I'll get the cpu model tonight. Wish we could upload pics here directly.

Hey vistarshook after seeing your temps on the pic I have decided to do go ahead and try out conductonaut. I have ordered that and the Super 33+ Vinyl Electrical Tape, what type of thermal pads to you recommend and thickness should I get. Also after seeing alot of videos on YouTube it looks very promising and hopefully this will solve my heat problems. Ill be sure to update my results and let it be known how it goes. Thanks and any tips and suggestions will be appreciated.

Vistarshook, wow, look at that PCH temp running prime, that is awesome! My 1070 is 47C just at idle. Wish I got that instead of the 1070.
 
BTW, my work MBP when doing office work runs really hot, almost everything is in red for the high temps. Its using a 3820QM.
