Installed ASUS GPU Tweak but can't find any fan slider/option. What should I do?

Being able to manually set it to max/default would be great, as I noticed it gets quite hot when I'm streaming something over on twitch.

Really no one has any idea?

My CPU is getting some pretty high temps, even with a hefty cooler stand underneath it.

what is your gputweak version?

I've tried both with the last version (2.7.1.8) and with 1.0.6 or something (some1 mentioned it in here). No luck though :(

cremvursi, the 2.7 series is for the non-Optimus laptops. The one you want is the Asus GPU Tweak for Laptops, the 1.0.6 version you found, but currently the latest version is 1.0.9, here:

Give that a try, someone else recently tried it and they got the Full Fan control option :)

cremvursi, if the Full Fan option doesn't show up, and it is an Optimus laptop, then that option isn't supported on that laptop.

You don't really want to be manually toggling On/Off screaming fan mode anyway.

What is hwinfo logfile showing for average / peak temps under gaming for the CPU/GPU?

My GPU Tweak is something like this (http://oi57.tinypic.com/2v2jt7c.jpg). Toggling GPU on full speed does nothing, it still shows 500 RPM (also can't feel any difference, no increased sound made by the fan or anything).

Max temp on CPU when streaming was something like 87 I think. No thermal throttle occured.

that gpu tweak only supports the latest g750 series though i may be wrong about this. Have you used the overclock option? If yes, then do you see any changes in fps when playing games with and without overclock turn on?

cremvursi, the Asus GPU Tweak for GPU has worked on some other models than G75JM/JS/JZ, but if the Full Fan control isn't working then at least that feature isn't supported on your g56jk-dm156d.

You can use Windows Snipping Tool to grab a shot of your actual dialog, so we can see what it says.

If your laptop didn't come with Asus GPU Tweak for Laptops, it is worth trying, but it isn't guaranteed to work. The Optimus laptops can't use the normal Asus GPU Tweak for Graphics cards, which works pretty much on all ROG Laptops except for the ones with Optimus.

On the laptops without Full Fan control feature, it will automatically run the fan as fast as it will run as needed. If your GPU fan isn't running at full speed it is because it isn't running hot enough to need full fan speed.

If you need to hear the limits of fan function, you can run prime95 small FFT test and Furmark Burnin 15 minute test to run up the CPU fan and GPU fan respectively.

Asus sets their fan curve to run the fan at low speeds to stay quiet, but keeps the CPU/GPU cool enough for normal operation. You won't have the fan noise intrude until the CPU or GPU get hot enough to require the additional cooling.

Nothing to worry about.

You can use hwinfo64 and turn on logging to create a .csv file you can read later in Excel to see the minute (or 2 minute) by minute reading for temperatures (and other data) - look for Thermal Throttling (changes from No to Yes) that is the point where performance is affected as the CPU throttles itself for protection against high temperature. Likely as not peak Termperature readings only happen occasionally - the rest of the time the temperatures will be in the 70c-80c range.

Please do come back and let us know how your laptop does with prime95 small fft test and furmark burning test - you only need to run them for 5 minutes - together or independently - to get a good max temperature reading - no sense running them for longer than 15 minutes.

Have fun :)

So, it seems that during streaming my CPU is throttling, max temp @ 91 degrees C. Screenshot below.

cremvursi, what do you want?

well you said that I should be back with some results after running prime95+furmark... I didn't do that but I returned with some pretty high cpu temps and thermal throttling that happened during streaming...

I want to know if those temps are normal... I mean, from my knowledge they aren't normal at all... I think that using a cooler stand with a 250 mm @ 850 rpm shouldn't translate into so high temps, considering the lappy has been bought not more than 2-3 weeks ago.

I want to know if there's a way to lower the temps. I want to know if I should call the guys at support and tell them about cleaning/replacing it...

Also, I did another stream tonight but I lowered the core and cache dynamic voltages by -50 each. That seemed to work a bit, lowering the max temp per core from 91 to 89, which caused no throttle to occur. But I am still worried about the temps, as anyone would be I guess.

cremvursi, what are you streaming? What is the game you are playing? Or are you simply serving play already recorded, what are you using/doing?

You have a small enclosed space in a 15" laptop, smaller volume than is in the 17" laptops, and they have problems with Thermal Throttling under heavy load. It isn't unusual with the move to squish so much hot hardware into a thin profile that the result for people that really use the laptop to do real work see limits in performance due to thermal throttling. I experience that with Macbooks, they always get red hot when I do my work with them.

At least with a PC laptop you have some tools available to moderate the performance to reduce the heat. You started with negative voltage offset for CPU/cache, and that's good, in fact it might be enough. It looks like you were right on the edge of Thermal Throttling and the drop in power usage and heat generation was enough to stop Thermal Throttling.

The other thing to look at is to enable logging in hwinfo and see how often the Thermal Throttling event occurs, and how often your peak temperature reading is actually happening during a session. Gamers that have done this note that it is only a few times during the gaming session that peak temps are reached - and only 1 or 2 times they have Thermal Throttling - the rest of the time the temps stay in the 70c/80c range.

Here is another thread where I posted the images and instructions on tuning with XTU to reduce performance enough to stop Thermal Throttling in follow-on posts.

http://rog.asus.com/forum/showthread.php?54521-Cpu-or-Fan-problem&p=457208&viewfull=1#post457208

You can likely stop all thermal throttling if you reduce the multiplier's for core 3/4, while increasing the multipliers for core 1/2 to the maximum.

If you want better temps, get a less powerful 15" laptop, or a larger 17" laptop with better cooling.

Otherwise, work with the tools available to get a handle on the performance / thermal environment available in your new laptop :)

Yes, I'll probably fiddle some more with XTU untill I get the best results.

I thought that the g56jk would have something akin to the Fan management that I used for my dell xps l502x which can be found here (http://forum.notebookreview.com/dell-xps-studio-xps/635536-l502x-modded-bioses-download-gpu-voltages-more.html). That is really a great piece of software that helped me a lot.

Thanks for the help. I'll come back probably after the holidays with some new results. Happy Christmas/New Year!

cremvursi, I know what you mean, it took me a while to get used to not having manual control of fans and other things, but in the end I am happy with the laptop and it takes good care of itself, even with me tuning up everything to maximum performance.

It would be nice if your laptop could cool itself enough to never Thermally Throttle, but it isn't doing it all the time during normal operation, only during heavy loads. It has more power than can be cooled under maximum load, but just so, as long as it isn't doing it enough to turn return it, it's a keeper.

Have you considered dropping / controlling the FPS? That seems to work well for many games that run way faster than needed. That will drop the temps too.

Happy Holidays to you as well :)

thank you, and have a Happy Christmas and New Year!
