Alright, So i recently bought a new Asus Rog G750JZ like a day ago with windows 8.1 on it ofcourse. The first boot and the first day of usage went flawless. The second day i go on and turn on my brand new machine and it`s normal, entil 10-15 minutes of usage and the fan started going really loud [ i could bearly hear it before that] and that was all from browsing the web and not doing anything. So i thought it would stop eventually, but it kept going till it stopped and started periodicly going from loud to quiete. So i went on the forums to search for a solution. I tryed tweaking the power plan, frankly that didn`t do quite alot... I tryed monitoring the temperatures and it was all good and dandy, nothing unusual. Tryed a factory reset on windows 8, that didn`t do all too much. Tryed using Intel Extreme Tunning Utility, but that didn`t help as well. As I`ve said before, the laptop is bearly used, mostly to research the problem and music along with it. So if anyone can offer me a solution, It`ll be gladly apretiated!
P.S Forgot to mention: The noise is mainly from the left fan, asuming it`s the CPU one.
Xectich, the fan/cooler, when working properly, respond to increased heat coming from the CPU - for the CPU cooler - and the JZ CPU also uses the Intel GPU onboard, so when you do something CPU intensive, and now GPU intensive that runs on the Intel GPU, the cooler will spin up the fan to move more heat out of the laptop.
If you aren't doing anything at the time the fan spins up, then a background process has started that is generating the CPU usage, creating more heat, and the fan spins up to cool things off.
Use the Windows Task Manager, Details tab, sort by CPU usage, and find out what is running in the background.
For me it was the media indexer that is part of the Asus / Cyberlink DVD - I went into the preferences and removed all the folders configured for indexing, and that stopped the frequent background running of that indexer.
Let us know what you find is the background process causing the CPU fan to spin up, others might benefit by knowing too. 🙂
I checked the task manager and nothing unusual. It went from silent to loud, but nothing changed in the cpu % usage in the task manager and the heat of the CPU was around 40C and proccesor usage was aprox. 3-4% tops at the time i was monitoring it, so I assume it`s not from a backgroud app that is running =\ [ tested it with only chrome and task manager oppened from a fresh boot]. Anything else I might try?
I have already tryed the tweak with XTU with -25mv, -50mv and -100mv, but nither seemed to solve the issue. I`ve set everything to run with the Nvidia GPU, but that didn`t solve anything as well. With the Intel GPA analyzer i don`t get the GPU options. Still trying to figure if there is a background proccess that is causing it, but can`t find anything unusual. Starting to feel desperate now, is there anything else i might try 😞 ?
Alright as I kept playing with settings and such I noticed that the fan was constantly going on, even in idle mod when i`m doing absolutely nothing. So i switched back through all of the settings i previously tried and there wasn`t any change at all. The temps are normal, the usage is normal, nothing unusual. I`ve added the XTU settings and the tasks running at the time the fan goes on in the attachments. Hope that helps to figure it out =\ It`s curently still going loud.
These are the proccesses that were running and causing CPU usage at the time the fan kick started and I have no idea what is causing it to speed up 😞 :
