Model: Sager NP8157/Clevo 650HS-G
Central Processing Unit: Intel Core i7 7820HK Quad-core 2.90GHz
Video Card: NVIDIA GEFORCE GTX 1070 8GB GDDR5
Memory: 16GB 2133MHz DDR4
1TB 7200RPM SEAGATE HDD
With this configuration, I am getting sustained temperatures of 93-97 degrees Celsius when using the following programs (generally run at 1080p and at the highest possible settings for games) listed below for any period over 15 minutes:
PLAYERUNKNOWN'S BATTLEGROUNDS
TITANFALL 2
DARK SOULS III
TOM CLANCY'S RAINBOW SIX SIEGE
INSURGENCY
KILLING FLOOR
NO MAN'S SKY
Or any game in my library, actually.
Tasks that also cause the CPU to reach such temperatures include:
Exporting footage through Adobe Premiere Pro using lossless codecs
Exporting footage through Adobe After Effects using lossless codecs
Strangely enough, benchmarks do not cause these temperatures. Both the latest version of Furmark and 3DMARK Firestrike do not cause the CPU to exceed 86 degrees Celcius, with an exception for Prime95 which returns similar temperatures of 90-94 degrees Celcius at its peak.
A repaste of the CPU has returned no improvement and neither has cleaning the system. I have left voltage as is because undervolting has returned roughly the same result at the expense of semi-frequent crashes.

Since there's no IHS with mobile chips it's unlikely to be the CPU at fault so it'll likely come down to pasting, heatsink pressure or possibly a failed heatpipe.
You should be able to tell easily if it's a pressure or heatpipe issue by feeling the temperature of the air existing the exhaust. If the air is cold then the heat is not transferring properly.Dr. AMK likes this. -
I agree that you need to use something extraordinary for thermal paste. Today's CPUs and GPUs run a little warmer than what most would consider ideal when all conditions are perfect and there is no such thing as going overkill on thermal management.
Nothing is as good as liquid metal. If that freaks you out too much, get some Phobya NanoGrease Extreme or Kryonaut. Anything else besides liquid metal or these two thermal pastes is kind of a waste of time and money. GELID does work good, but I have not found it to be as durable as Kryonaut. And, you're going to have to undervolt. If you leave the voltage on BIOS defaults your temperatures are never going to be good. If you found it was unstable, you probably were either too aggressive with the undervolt or maybe another setting wasn't right. Each CPU is different, so some will require more voltage than others.
Another thing about this that is often not understood is higher temperatures requires more voltage. What I am saying is that if undervolting is not working, you may have attacked the wrong problem first. So, if you get some good thermal paste on it and make sure the heat sink is actually making good contact (lack of which can be a huge problem) that same undervolt that was previously unstable may actually end up working out fine if the CPU is running 10°C to 20°C cooler. If it runs cool and still crashes, then undervolt a little less, test again, and keep making small decreases to the undervolt until it becomes stable.Dr. AMK likes this. -
93-97C is still too hot (assuming a 20-25C ambient) for a properly functioning setup under a regular gaming load. Given the CPU and GPU heatsinks are joined together you'd have to repaste both each time which could waste a lot of TIM.
Still don't understand who's bright idea it was to add in that joining heat-pipe though. It literally makes the entire cooling solution worse in the P650HSMr. Fox likes this. -
I've just repasted with IC diamond, as it was already using that to begin with. Admittedly, the air exiting the rear exhaust seems to be cooler than the air exiting the left side, but not necessarily cool enough to warrant a failed heatpipe. If it is however, how would this be fixed? -
If you're still seeing asinine temps like before with fresh IC Diamond, you've got a problem with heat sink fit or a defective heat sink. If it is under warranty, I would contact the place you bought it about making things right, which would likely mean returning it to them and having them replace the heat sink with one that works right.
You should at least try a modest undervolt (say -100) to see if the needle even moves in the right direction on the temps. If it does not show signs of improvement, then I'd send it back to get fixed or ask them to send you a replacement heat sink in the mail.

For the purpose of testing, if you use FN+1 and force the fans to run max speed does the CPU still get that hot? When not forcing the fans to run full blast and the CPU is slow-cooking itself, do you hear the fans ramp up? At 90°C sustained more than 5 or 10 seconds, the CPU fan should be howling full blast at that point. -

If you have an unlocked BIOS it is a menu item. If not and you are using ThrottleStop, having the C1E box unchecked will do it. If c-states is not disabled and your CPU is running in Turbo Boost mode, when you are not using it that could mean there are processes running in the background that are loading the CPU. With the system idle, start Task Manager and look on the Processes and/or Performance tab and see what percentage of CPU is being used. It should be at or near 0% most of the time with nothing else running. If it is more than 1-2% you need to see what is running (look on the Processes tab) and consuming CPU cycles. It could be Windows Maintenance tasks. Malware will also cause this.Vasudev likes this. -
Skimmed. Who is your vendor? These temps are so far from normal, you should be experiencing somewhere around 30c less with battlegrounds using max fans on your CPU. I believe if no repaste helped at all that you have a bad heatsink. Your system is not functioning CLOSE to normal.

Are CPU temperatures of 93-97 degrees Celsius for this NP8157 configuration?
