Been reading all the thread and seeing what needs to be done to get temps down but how much do low temps effect fan profile and speed?
I did the liquid metal repaste and it helped to get temps down. Also when doing the repaste I found out that the CPU heatsink screws were lose. I was able to unto them with my finger.
Back to the fan profile. I have been able to use the PC more and see that fan speeds seem to throttle up fast. Mostly after GPU temps reach 65°C the fans turn up to 90% according to Alienware OC (cant seem to find any software that shows actual speed).
Only thing i did notice was that the PCH was around 70°C and my samsung 960 pro when up to 80°C.
That is hot but for machine that does not help to cool the SSD why would this effect fan speed ? It is not like it is drawing air from the under the armrest side and in doing so cooling the SSD. Its like if on a desktop my GPU was running hot and case fans would speed up.
I used the server room at work to run a few test just using the AC.
First image is with no AC help running on a cooling pad. (No fans running on pad)
You can see here PCH and SSD temps that are a bit high and fans were going from 95 to 99%
After using the AC to help temps. Not directly just was blowing air under the cooling pad. Fan speeds were around 42% just to see what would OC would do i turned it on and fans instantly jumped to 65% and then 53-60%
I might still be used to the temps and how the AW 18 2013 ran but to me fans should no even be on or over 20 % with temps like this. To make things even stranger as soon as you turn off OC fans turn off (idle) and then turn on again in about 20 sec but now at a lower speed.
Been reading a lot of comments that older bios kind of seemed to be better ? is this true ? I got the machine with the latest bios installed.
I will install a SSD cooler and try the PCH mod but at the moment it seems like it will not help at all as the fan seems to have a mind of their own and work as they want to regardless what the temps of the CPU, PCH, SSD and GPU temps are.
Also starting to think the HWinfo fan values that are under fan control do not show actual speeds. Might be a scaling mistake.

Well been fiddling with the fans and was able to try out a "custom" profile. It is not the best as i only have 6 trigger points but it seems to work for now. Will have to try a 1-2h gaming session but as for a 30 min one all seems to be OK temperature wise.
Also fans do not go over 3400 RPM witch is good as about 3500-3600RPM the fans get loud.
Load temps were around 75-77°C with a few spikes up to 82°C on the cores but other then that the temps do not seem crazy high and I am able to play without annoying my wife with the loud fan noise.
One thing I did see was that HWinfo does not know what fan is what. What i mean is that the CPU fan under custom control is actually the GPU fan and the GPU fan does nothing at all. I made the mistake at first and saw temps going up to 90 also the SSD started to throttle. After correcting my the mistake this is what i ended up under GPU settings. As the heatpipes are shared the temps should reflect both GPU and CPU and you can see that the temps idle at load as mentioned around 75-77°C
I do not recommend using these settings as they are set for my machine with a repaste. Stock machines might have dif. result so i do not recommend it. I you want to try first monitor your temps and start to make tweeks.
For me the stock fan profile stills seems to be to aggressive. Here is a stock fan profile in action. The benchmark tool has already closed and not running but the fans spin at 4200 RPM around 2 min before starting to go down but temps went down to idle almost as soon as the app closed.
This is just my observation. It might just be my machine that seems odd or i just might be crazy.
