So the temps of my cpu are hitting 90-100c after about 30minutes of play (The Division). After about an hour, the computer straight up shuts down..assuming this is because of temps. That being said, what recommendations would you have without me repasting first? Fans are kicking up fine..wondering if I should force max rpm via HWInfo64. I got this laptop the end of January (brand new from Dell). Haven't repasted or anything since I got it. If you suggest that I repaste, what paste would you recommend?
Hindsight, I probably should've gotten the 4910 cpu as I do no overclocking.

I have the same config as you do more or less. I very highly recommend you do the following:
1. Repaste with Liquid Ultra. this will give you the absolute best temps possible.
2. Download and install intel XTU and play with the dynamic voltage offset and multipliers. I have my 4940MX set to 40 40 40 40 with a voltage offset of -100mV, so under load 4 core at 4.0GHz, the voltage is about 1.1040V and temps typically middle around the 75-78 range after extended use of gaming, and around 80-82 if encoding a video. on stock paste I was bouncing off the thermal throttle limit. Haswell is hot. Alienware stock paste is junk. CLU is the only way to go, with proper tuning in XTU. -

Thanks! Is the brand for Liquid Ultra, Coolabratory?
Also, I see the options for multipliers, but which one is specifically the dynamic voltage offset? I see a couple different voltage offset settings.Last edited: Mar 17, 2016 -

Ok, so I've been watching some youtube videos on applying Liquid Ultra on the cpu. I'm confused to why you have to apply it on the heatsink as well. Also, how in the world do you know where to draw/paint it out on the heatsink--like are there lines drawn on the heatsink that outline where the cpu is?
-
Put some paste on your cpu, place your heatsink on the proccesor and take it back of now you can see a nice square on the heatsink
-
you can definitely see where the CPU contacts the heatsink, especially if it's been running hot. You apply to both CPU and heatsink to ensure a proper bond is formed

Update: Applied Liquid Ultra on the cpu and heatsink and Wow! 15-20C degrees difference at full load! Thanks for the suggestion guys.
Was thinking about also applying it on my 980m's while I had it opened, but they have been fine temperature wise. Liquid Ultra is the real deal..I'm a believer. Thanks Raidriar for the suggestion. -

Don't use it on the GPUs unless you put a shield over the components around the die. (Clevo has a shroud on their GPUs where the electrical tape is applied. Dell does not.) You can use electrical tape strips, clear (non-metallic) nail polish or liquid electrical tape. If you get any Liquid Ultra on electrical contacts it will be a bad thing, so this is cheap insurance. It will also destroy aluminum if you leave it there. Unless you are having thermal problems with GPUs, you don't really need it on them. Using a decent paste that cleans up easily (IC Diamond, Gelid GC Extreme, Kryonaut or Conductonaut) will be just fine in most cases for GPUs since they usually don't run as hot as an overclocked CPU.
Here is a before and after example of using electrical tape strips on the 780M GPUs in my AW18.
After almost a year of use the electrical tape looks the same as the day it was applied.

dem scratches tho
._. -
If you are talking about the photo on the right, what you see in the middle is a dob of Liquid Ultra. That would be a really nasty looking crater in the die, but I have been asked about that before.chewbakaats58 likes this. -
I didn't though that it could be perceived that way hahaha

When I did the liquid ultra paste, the step before had me buffer the cpu die..at that point it got scratches all over it. I assumed that was just part of the process. Like Fox said..as long as temps are good, I could care less what the die looks like.
4940MX overheating
