I've have my SC15 for a little over a year now and while it has been running very well most of the time some issues have started to crop up. Any help with any of these would be fantastic, I have enjoyed this laptop very much so far.
 
I've undervolted -115mV on core and cache using throttlestop a while ago
 
a) Lately there seems to be some kind of burnt smell coming from the fans. It is very subtle and not like smoke or anything just a mild burn smell. Perhaps it's the smell of old dust or singed circuits. I have done a good job of keeping temps (CPU and GPU) below 90C (usually around 75-80C with less CPU intensive games) - using the fan boost whenever gaming on a clean hard surface and even propping up the back for more air flow, so I can't really see any particular reason for this smell. To be fair I have used the laptop for gaming quite regularly and for long periods so perhaps it's due to long-term low temp burn? 
 
b) In the last month (every since I installed COD infinite warfare) I have been experiencing memory dump crashes or similar while playing a few games, and some mild graphical hiccups or abnormalities. I also get the occasional BSOD crash for different reasons, sometimes while game is running sometimes not. It seems like I have a problem with RAM, SSD, HDD, or GPU but having run some diagnostic tools for each no errors have been found ¯\_(ツ)_/¯
I've installed new Nvidia drivers a few times so perhaps I could wipe all of the old ones and install the newest but I don't think it will help much. I'm a little worried I've damaged the GPU (I have used precisionX with the superclock mode a little in the past but didn't notice much improvement so stopped using it a while ago) but since I've kept temperatures below 90 at all times I can't see how.
 
c) a small last thing I noticed is that precisionX is showing my GPU clock is at 1400MHz even when at Idle on battery which seems excessive...


Should I worry about the slight smell and what can I do to stop these crashes?
 
 

other than blowing air with a can of air how can I easily clean the fans? The screws on this laptop are not normal and I'll have to order a screw driver with a special star-shaped head to remove the case, which I believe voids the warranty no?
 
I actually recently bought a laptop cooler- very cheap from a shop but I intend to get a better one.
 
Yeah I'll do the DDU later tonight
 
Windows 10 version 1809 installed in april 2019
 
I've restarted numerous times, same graphical hitching. For example while playing battlefront 2 (2017 version) while walking around on a particular level the textures on the ground keep changing right infront of me, like they are adjusting detail level but very visibly. Not something I've seen before. I have weird texture issues in other games too, but just little flashes of abnomal textures (white/checkered/black) but too fast to see properly.
 
Have a few things running on startup/manually opened after startup though: Throttlestop, f.lux, dropbox, onedrive, precisionX, avast antivirus (I use windows defender).
 
Settings on Battlefront 2 are maxed out everything, running around 60-80 fps. Just tried GTAV and also there are weird texture problems visible at times - almost maxed out everything.
 
I have the 1080p panel with 120hz refresh
 
I've attached the nvidia control settings. Just changed power management mode to adaptive and preferred refresh rate to application controlled to see if the gpu clock will lower at idle but it's still at 1400mhz

Sounds like your gpu has a problem. What happens if you underclock your gpu to max negative values on the core and memory?

Okay.

Sounds like it is a hardware fault.

Dropping your CPU temps will also help keep your GPU cooler in these systems. Make sure you have PXM installed, you should try undervolting your CPU and setting a fan curve with 75c as 100% fan speed for both CPU and GPU. A good safe undervolt on the SC17 is about -50mv, but your experience may vary since you are on the SC15. Make sure that you save those changes to a new profile on the left side of PXM and activate the new profile every time you use your system for the best results. I also recommend dropping the CPU max clocks a bit, but thats just what i would do. The drop in performance is negligible for a pretty good drop in overall temps.
 
The bits used for the back of these laptops are standard T5 (iirc) Torx and after the bottom of the case is off the rest of the system uses standard philips (+) screws. If you want to clean the fans and re-paste the CPU/GPU its a very straightforward process and might also help with your temps. Someone else on these forums by the name of kaneorotar has already posted some pics of how to disassemble the SC15 here: https://forums.evga.com/H...eir-SC15-m2823990.aspx

use a Laptop Cooler..... I use one
 
Wonder if the battery / power circuit is the source of that heat ?
 
You should run a deep security scan with up to date signature files - just to make sure the system is clean
