@John Doe:
The Helios 700 comes undervolted by 0.11V ( you can also see this on some screenshots);
The cooling performance is extraordinarily on this machine. I have tuned the "boosted" mode (that's the correct name for the mode when you pull out the keyboard, btw. - "fast" is the one where you press the turbo button with keyboard in normal position...and a totally unnecessary mode. As it is loud and offers no real OC performance. Acer should have gone with "silent" & "normal" for keyboard in standard position);
I do agree with the fan settings. Set mine to manual on 1200 RPM CPU (I own the 9980HK version) and 1200 RPM GPU for desktop usage. Almost inaudible, CPU stays within 40 to 60 degrees C° and GPU around 40C°;
I hope they fix the inconsistant cooling profiles in later Predator Sense updates.
I manually changed the OC profile of Predator sense, now my GPU runs at +180 MHz and VRam at 2000MHz (never goes above 68C° with "boosted" mode, which does not put the fan at max RPM and keeps it around 50+ db); Easily broke 11k points in timespy this way.
If Predator Sense let me change the CPU profiles as well ( The XTU profiles can be changed, but crash the profiles) results could even be better, as the CPU runs very well at - 0.13V at all cores 4.7 GHz without throttling.
Sadly my screen has some terrible bleeding as well, could correct some of it by loosening some screws under the bezel a little. For that price I certainly expect more quality control and Acer should be ashamed of what they deliver here.
The keyboard is nice, but it swings minimally, which can lead to some reverb sounds when you hit the keys on the middle/right with medium force.
Disappointed by the subwoofer, the bass is not quite strong, at least your neigbours will not be disturbed by that. ( They might be when you put the machine on "turbo" mode or "turbine" mode around 60db with fans blowing hard. Only use that mode for benching. )
I like the touchpad much more than the tester, for me the position and buttons feel quite right, but that is a very subjective point.
Overall I am very happy with my machine. While it is not as fancy as the M51 it outperforms it slightly (at least mine after some manual tuning) and costs about 3/4 of the price of the alienware laptop in Germany.
Do not mind the weight, got a great laptop bag and am a healthy male, so whatever ;)
If Acer adds better fan profiles or gives the user the possibility to easily create own fan curves and more control about PS tuning without the hassle to download XTU etc, then the machine would be a dream.
I am no native speaker, so please do not mind of my grammar and vocabulary is not always spot on, feel free to correct me, so I can learn :)
