Nitrox, I don't think the NBFC is at a point to recommend to everyone, if miss set up and left on automatic NBFC can overheat the GPU at idle - it is too dangerous to use, and I stopped using it.
The G750's/G751's are designed to automatically cool as needed.
You can become overly concerned with running the chips cooler than needed, it isn't necessary for the long term life of the chips, and distracts from the enjoyment of the laptop for gaming.
If you are having cooling issues, you are thermal throttling when playing games / running apps, then you can RMA the laptop or return it, as it shouldn't be doing Thermal Throttling in games/apps.
If your use is such that you know you are overtaxing the system - like running long term batch jobs doing rendering / computing - that when running on all 4 cores puts the temps near throttling, and Thermal Throttling occasionally gets triggered, then you can de-tune cores 3/4 a couple of steps, say from 34x to 30x or 32x to assure full performance.
Again, NBFC isn't a reliable tool yet, so I would stop recommending it for so many to use. Wait until you and the developer work out all the bugs 🙂
Thanks for your enthusiasm and please do understand I encourage this kind of experimentation, but you will find lots of people aren't as diligent in monitoring as you are and might not catch that they are cooking their GPU's with NBFC at idle.
OC'ing CPU's / GPU's in the range the normal BIOS/vBIOS set won't damage a CPU/GPU, but messing up cooling will.
I would suggest the 3rd choice not say NBFC is useless, I would say NBFC is dangerous and not ready for general use.

Yep, I totally agree with you that it could be dangerous for the entry level users but it isn't that dangerous for any user that knows to download HWMonitor/HWInfo and keep an eye on the temps. Also, making use of your ears is also a good tool to check if the fans are working :).
I have been testing this program for a long time now, and can say that it is reliable once your understand how it works. And what I have tried to do is to raise the CPU fan a little bit. From my tests I have found exactly what I was assuming 2 months ago. The CPU fan has a different default profile than the GPU one and this is why the cooling on the GPU is way better. I have explained in more detail in the posts. The fact that the CPU changes it's cooling state much later than the GPU determines an accumulation of heat inside the case.
I am definitely not recommending it to everyone. I just recommend it for the people that know about it and who want to control their fans.
I'm just trying to provide a starting point and as much information as I can so the people would more readily understand the applications features.
By the way, the GPU has nothing to do with this profile as I only made a profile for the CPU. The GPU is already cooled better enough so I don't really see the point of changing its default profile. There are several reasons for not doing this and I have stated them all in the long posts.

Yeah, I am aware of the risks implied by using this sort of application. I have also had my bad experiences with NBFC when I started changing values without knowing what I'm doing and I ended up with the battery led blinking orange, the battery wasn't charging and the laptop went into a sudden sleep mode. I got scared like hell in that day... but it seems that it was sorted out quite easy by resetting the EC.
As I said, I'm not recommending the program to everyone. I've added one big highlight about this in the first post as it certainly implies some risks playing with this sort of software.
By the way, when you were using NBFC did you only use the pre-made profiles or did you made your own profile for the G750 ? You said something about the GPU fan curve. Did you checked the EC Table to see which values were changing for the fans ?

NitroX, when I realized it was unfinished, and there wasn't a G750 specific profile, I experimented with using similar profiles with user level configuration changes, and found 1 profile that worked with CPU only, then later found 1 profile that worked for both CPU and GPU fan setting, and was excited at the potential.
When I came across the faulty automatic mode, with the resulting over-temp for idle on the GPU, I looked at the source code.
After consideration I decided it wasn't worth the effort as my G750JH CPU/GPU temps, and the G751 temps I was seeing, weren't bad and didn't require any help from something like NBFC.
Over time I have come to realize that there is much to enjoy about being able to rely on the vendor engineering, rather than assuming I can materially improve on it myself, and spending a bunch of time improving what doesn't need improving 🙂
I do find and fix problems with Windows / apps, recommend optimizations for better performance through tuning, but if there is an actual system problem / shortcoming it is the vendors responsibility to fix it, so I report the perceived problem to Asus and work with them to get it fixed.
If you want to de-tune the CPU/GPU to run cooler that is up to you, or if you want to OC the CPU/GPU that is up to you too, and the Asus automatic CPU/GPU fan curves cover both situations.
We paid Asus to engineer the laptop for safe long term use and best performance, and I think they have done that. 🙂
NBFC is the first time I have run across something that I think can be dangerous/injurious to the laptop, that is why I am recommending not to use it.

I don't know guys, this sounds complicated...and I am using the profile that is called "Silent" that was uploaded by wishmaker or some one I can't remember, back in the old post about fan profiles.
I is realy awesome, I have been playing on it for almost 2 months now, and it has never went up over 80 degrees on anything.
Like 76 degrees on dying light after a lot of hours....
Every temperature is like 10 degrees lower then without this profile.
I don't want to mess around with steps and R/W values, but this profile is awesome !
It's the best profile and realy agressive, I can't recommend it enough !
Just put the profile in to the program, turn it on, and your temperatures will be stone cold !
Best profile out there, and I have used every type of stress test, gaming test, idle test, combined test..... Awesome !

JasenDoe, I don't want to say anything bad about Wishmaker's profile. He was the one that convinced me to go this far. But I have clearly explained how important is to set the values right and I have also explained how I have set the values for each step. I cannot tell wether WIshmarker's profile is stable or not as I do not know how he ended up making it. But I do know that he said he made it from the Zenbook UX32LN which also has some values written in the "Read Write Configuration" that might cause problems in the EC Table.
I have talked with the developer for the past week and he strongly advised me to make a profile from scratch in order to avoid any interfering with the EC Table.
Now, it is your choice wether your want to test my profile or you want to use Wishmaker's one, but please do not start recommending profiles without having some basic notions about how they work.
