Re: Bring back fan control to the Legion Y740

2019-10-15, 23:37 PM

When I first got my Y740/9750H/2070 I was using an undervolt to keep the temps in the 70/80s range.  I have since started using the TPL function in thottlestop which seems to give me the best performance. Im big into online mp games so every frame counts.

Also which benchmarks do you guys use to test out the temperatures and how much you need to undervolt by. I read about Cinebench and timespy. Will I NEED to play any game for better temp results or the two aforementioned benchmarks should be good enough

I have chosen not to undervolt for now. My laptop is pretty much out of the box stock. I use CPUID HWMonitor for temp readings and games for testing. Usually I just leave HWMonitor on background and after my game session I check the max temps. I have an opportunity to install another monitor so I can have livedata on that, but I have used it only once. I have tried also OCCT for testing and temps, but I think games give me better data. For some reason what comes to temps on my laptop the Balanced mode is the worst and Quiet the best, but in Quiet mode for example Doom fps drops from 120-144fps to 90-144fps. Which I can not see actually, but for some more CPU demanding games you might see the drop. I will test FarCry3 today. I have been playing it with Quiet mode a lot last days and temps have been about max 88c° while fps has been round 55-75fps. I just want to see what happens on Performance mode.

 

Edit / Update:

 

Tested FarCry 3 and decided to continue with Quiet mode for now.

Quiet mode - FPS 64-75 and Max heat 87c°

Balanced Mode - FPS 74-88 and Max heat 95c°

Performance Mode - FPS 74-91 and Max heat 99c°

 

I cant see the difference while gaming so no need to push the CPU I think. 

 

If I get a game that will drop below 30fps on quiet mode I have to use the other two modes.

Is there a limit on edits? My post just disappeared after editing it.

 

My FarCry 3 test results:

 

Quiet - CPU 87c° - 64-75FPS.

Balanced - CPU 95c° - 74-88FPS

Performance - CPU 99c° - 74-91FPS

 

So I will continue using Quiet mode until a game comes that will need other modes. I cant see the difference on 60 to 80 fps while gaming. When fps goes under 30 I think even I will know. So no need to push the CPU I think.

@ananaspizzamies

You are right, the CPU performance in quiet mode is more than enough to play most games since they normally don't need the extra CPU punch, however, the game you tested it on, Farcry is one of the few that really needs the CPU to perform, and it shows in your results, the 10-13 FPS bump you have between quiet and balanced is likely caused by the jump in the CPU power limits.

You must remember that the performance mode raises the GPU power limit from 80W to 90W (2070 max-q), so that can make some difference in GPU intensive games like Battlefield

Disregard the GPU power limit comment, since you have the y540 2060 I don't know the GPU power limit situation, sorry if I confused you...

It's OK. I don't know that myself either, but GPU is performing very well and stays cool in any mode so it is not that important to know for me.

 

But what comes to CPU I want to keep it little cooler than 99c° if possible so I will continue using Quiet mode until we get Max Fan back (or I ran into a game that does not perform in approx. 60fps with Quiet mode).

Use throttlestop, you dont need to put it into quiet mode because your cpu temp is to high. Oh. and also set up msi afterburner so you know what the hell is going on with your system when your gaming.  It tells you everything you need to know to make adjustments to your specific system.  If your already using it great!

I will look into undervolting etc. when I buy a game which does not perform somewhere round 50-60FPS minimum with Quiet mode. Other games I have tried have had FPS round 100 (Doom) some up to 144 (BioShock Infinite) with Quiet so no need for me to start messing with things I do not know about. For now.

Re: Bring back fan control to the Legion Y740

The fans can be quiet loud without headphones, especially in a social environment, like a library, when a game (e.g. "Pillars of Eternity") is running with 144Hz synchronization to the laptop screen, even when the laptop mode is set to quiet.

 

But when it's running on battery, then the game becomes capped at 30fps, which is enough in my opinion and the fans stay quiet. Isn't there a way to cap the game ("Pillars of Eternity" in my special case) to 30fps so the fans stay quiet?

 

The laptop somehow does this when running in battery mode, but how can I achieve the same thing with it's running on cable?

 

All of this with respect to activated hybrid mode.

Its a high powered laptop, its going to make noise. If your going to be in a library I wouldnt bring a gaming laptop. This is a desktop replacement.  

 

I understand not wanting to make noise but this isnt the laptop for you if you need to be ultra quiet.  

 

To answer your question tho, you need the temps to stay really cool if you want it to stay quite.  I would download thottlestop and change the TPL settings to prevent the CPU getting to hot which is what causes the fans to kick in.  Start with changing long power max from 90 to 15 or 20 then change the short power max from 45 to 10 or 15 and work your way up.  Test the noise as you increase power to a point that is to loud then just use the last setting. 

 

I would also download HWmonitor CPUID so you can monitor all your temps or MSI afterburner like I have in the video above so that you can monitor your in game temps along with all the other data you need to make a informed decision about what settings you should be changing in thottlestop so that your noise levels stay down.
