Fans actually turn off on the G73JH

After downclocking my GPU to 100/200 clocks, since my idle temps have dropped down from 60C to 45C, my fans actually turn off. I thought this wasn't an option in the G73. I thought it ran all the time...

It's sort of a pleasant surprise, but it turns off/on every few mins when the GPU heats up 1C too much. Without the fans, the laptop is absolutely quiet since I run on an SSD.

Also, does anyone know of an accurate software to detect fanspeeds? GPU-Z only states 30% or 100%. Usually 30% with 100% under full load. When the fan stops it still shows 30%.

 

Try Everest Free edition, it's the only programm which seems to detect fan speed in my G51, so it should work with the G73.

 

It does indeed turn off the right fan but it never runs as slow as the left fan which is for the CPU.

Asus needs to update it's vBIOS like MSI and downclock the memory also. This will generate less heat which means the fan can be made to run slower at idle. Asus support really disappointments me at the moment. Why can MSI fix this but Asus can't? And why do they have to take things so slow?

 

Hrm, I'm using a gadget to monitor GPU temps and fanspeed- forget the name at the moment, but it shows mine as 0% fanspeed all the time. Occasionally it'll bump up above that. You may want to check your power settings- I have a lot of mine set to passive cooling.

 

How do you set it to passive cooling? I thought that the fans were on all the time on this laptop.

 

I think what aramis109 is talking about can be found here:

1. Go to "Control Panel" and click "Power Options".
2. Click "Change plan settings" on the active plan.
3. Click "Change advanced power settings".
4. Expand "Processor power management" branch.
5. Expand "System cooling policy" and toggle relevant setting.

I'm not 100 percent certain that's the only setting that needs changing, but that is the most likely. As far as the noise is concerned, it doesn't bother me.

That's it. Can also change the GPU settings and turn on Intel DPST as those'll probably generate less heat and thus less fan, though that may not be desirable for some.

 

Yeah mine do this on 100/200 too, does anyone know of a tool that can control the fan speeds manually? I want to check what temps do when the fans are on low or off, or if there are other available settings.

I don't think Active/Passive affects the GPU fan (it should do the CPU)

I also don't know whether the chipset or the GPU controls that fan.

 

Maybe ATI Tray Tools? On my other computer I have ATI Tray Tools set to run once at boot to control the fan, but I don't know if it would work with the HD5870m. I remember reading a little while back that the OC'ing part didn't work right and caused a crash. I don't know if later updates have fixed that.

Edit: According to their forum, it hasn't been fixed and needs to be installed with OC disabled. Has very limited support for Mobility cards. Probably too much trouble.

 

Is controlling fan speeds in the G73 possible via software?

 

Its is for any computer with a fan connected to a mobo or GPU fan header and that you know can change speed.

So yes, but I don't know if a program's been written to do it, or if a compatible program already exists.

 

The fan speed is control via BIOS, it reads the temperature from the sensor and the thermal policy on the BIOS has preset speed for the fan for each level of temperature.

 

So, I wish there was an app that can control the fan speed of the gpu. Cause i want to set it at full speed always because of the weather here in the philippines, Its so hot. Even my room temp is 33c.

 

Do you think this will work?

Unfortunately, speedfan won't work

The only way to set your fans to run at max RPM all the time is to edit your BIOS. This is extremely risky if you have no experience with the coding and may brick your system.

 

Shoot. Cause i don't care even if the fan noise is loud, The important thing is to make it cool even without too much load because of my weather.

 

You could invest in a cooling pad if you're worried about the heat.

 

I have a cooling pad, The aeoulus. but it just helps around 2-3c. Im just disappointed because i cant get the max out of the fan for the gpu.

 

How hot is the GPU running? What is the temps of all three TSS numbers? If the GPU is hot, the fan will run at 100 percent. If the fan is running already at 100 percent then you may need to find better cooling. If on the other hand the fan isn't running at 100 percent, maybe the GPU doesn't need the fan running that fast. Just a thought.

 

At idle this are my speeds.

Tss0-60c
Tss1-68c
Tss2-62

And i don't think that the is running atleast higher speed.

 

jearnarchie, that's too bad for you. I have never ever heard my fans go on full. I know my fans go on full around 83C and my GPU has never reached those temps even during gaming with overclock.

But you had to know of this as the G73 is being marketed as a quiet gaming notebook, so you have to expect that.

 

That's a bit confusing. You've never heard your fans go on full, yet you know they go on full around 83 °c?

jearnarchie highest idle temp was 68 °c. Your temps never reach 68 °c during gaming with overclocking?

 

Someone correct me if I'm wrong, but IIRC it's not until TSS0 and TSS2 get above 95 °C and/or TSS1 gets above 105 °c should you get worried about heat. TSS1 is usually hotter. Considering where you live and the GPU temperature of 60's, it doesn't sound like you should be concerned at this point that the fan isn't running at 100 percent. You won't see much lower idle temps unless you underclock the GPU.

I realize that doesn't answer your question about running the fan continually at 100 percent, just trying to ease your concerns about the heat.

 

My fans have never cranked all the way up on this X2 or my previous BB version. I also do not get high temps on the GPU. Never seen anything over 70 using the AMD tool.

Do you think this has something to do with the games I play; mainly RTS and RPG -- no FPS. Only Company of Heroes uses DX10 the rest like AOEIII and TQIT are DX9. None seem to tax the GPU. I do use a laptop cooler.

This beast is near silent compared to my now sold MBP 2.8 nvidia 9600m when running Windows 7 and playing ANY game. That machine sounded like a jet preparing for takeoff.

Cheers,

 

I can't really say for sure, I'm not a gamer. When my laptop is not being used it folds proteins. Right now the temps are:

TSS0 = 82 °c
TSS1 = 89 °c
TSS2 = 82 °c

The fan spins up and then slowly decreases every minute or so. Of course, the GPU is at 98 percent load, and according to Windows Uptime v1.6 it been like that for 3 days, 12 hours, 55 minutes and 12 seconds. Room temp is about 70 °F. As summer approaches and outside temps reach 100 °F, I may have to invest in a cooler.

I don't know if it's my imagination or I haven't been paying attention, but I thought the fan operated in a square wave pattern. You know, up, down, up, down. Now the fan seems to spin up and then slowly go back down. Never really hear it drop, just spin back up. Hadn't noticed this before.

 

It's called a Variable Speed Controller for the fans, Kalim. (waves back )

 

Although I already knew this, thanks for that information. [grabs a slide whistle and makes a sound ]

However, I wasn't talking about the speed controller so much as I was describing how the fan operated on said controller. As you already know, the controller can be programmed in many different types of variance. I was certain that it operated in a square wave pattern. With distinct levels. Now it operates with a burst and slow decay. Was this always the case? Was it always a burst and slow decay or did the BIOS update changed how the fan operates?

 

Works that way for me, but mine came with 206.

 

Ah, okay then it's been like that all along. Hadn't noticed the slow decay before. BTW, mine came with 205.
