[G73JH]Controlling fan speed

Hello G-lovers,

I am a somewhat happy owner of a used G73JH, with one major problem that both the previous owner and I have failed to resolve: full fan speed all the time. It is really frustrating to have to bear with the fan noise, given that reviewers have raved about the unusual silence that this machine can operate with. Well, as I wish well cooled equipment, I never expected "silence" while gaming, but definitely while browsing the Net or similar tasks.

The "strike in silence" idea got me originally interested in the laptop, but there is no situation when the fans spin at less than full speed.

I have tried all the official BIOSen from the ROG site with no difference; regardless the CPU used ( and regardless its use ) the CPU fan is always at full speed.

The GPU fans is always at full speed, which does not surprise me tbh as the graphics card is not an original ASUS card.

Still, I am thorougly amazed by the fact that there appears to be no solution to the problem on the Internet, as if nobody else has the problem. Users like me, who purchase used equipment, have not even the means to RMA our units - so I am at the point where I get the idea never, ever, to buy used ASUS equipment.

I post this to wake up somebody who can do something about the obvious bug in the laptop or at the very least I wish to see if there is enough people around with similar problems.

I had to reset my CMOS when I used a program to force my fans to 100% that was the only way, you could also try flashing your BIOS again to see if that fixes it. Are they at max speed from the moment you turn it on? Or gradually increase to that speed? I am sure you have checked this already but are your temps ok? That would be a common reason for it.

 

Just build yourself a solution by using a temperature-resistor (Negative Temperature Coefficient Thermistors - NTC), a technical part which is increasing the voltage (Decreasing the resistance) once it is getting hotter (So once the airstream is getting hotter the fans get faster, by default they are quite slow). I used similar solutions in the past when no real / payable fan controls existed in PCs.

Building a simple temperature based fan control is easier than baking pie.

Edit: I found an example for you here: Simple temperature regulated FAN speed controller

If you are a bit sceptical for this solution and don't trust me ... well Trust me, i'm an engineer ! - YouTube xD

 

Thanks for the fast responses

Yiddo:Temperatures are wonderful; usually no higher than 11 degrees above ambient air. Heavy load offsets this with 50 or so degrees; still not a bit of a problem - this computer has very good cooling

The fans are instantly at full speed. There is never a rev-up; there is never a hint that something tries to control them - they are constantly at full speed, simply, unquestionably.

Crogge: Yes I can build fan controllers; have been using custom solutions many times on my self-built rigs, but never on a laptop. I have always used Clevo derivatives, with wonderfully effective cooling solutions.

I still wonder - do people just live with the fan noise?

Gotta be a hardware issue, have you tried resetting the CMOS/flashing the BIOS? Seem to remember someone had something similiar and had to RMA when both didn't work.

My JH was always quiet and after repasting it never went above 3200RPM on either fan when running flat out so there must be a fault somewhere. What was mentioned above should work if you know what your doing lots of people have connected regulators to control the fan speed manually.

 

Well there is no real difference if you build a simple fan control made of 2-3 parts for a PC or a NB, fans work in the same way. The solution I posted in the link above is automatically regulating the fanspeed AND allows you to change it with an regulator additionally. The switch is optional and simply disables the NTC to let it run at full speed if needed.

Using only a simple regulator without an NTC is a bad idea Yiddo, you have to control the fan all the time yourself then and if you forget to push it up while you stress the GPU it can cause in the worst case (Even if its rare) a hardware damage.

 

I have no clue or idea what you are talking about its way too advanced stuff for me I was just saying that people who have done what you are on about has worked for them. I do not know the entails of what they did hence why I said it is an option for the OP to look into but I wont be explaining it

CMOS or Bios is my recommendation.

 

Well my suggested solution should be only used if the your suggested BIOS reset won't help.

It is basic technical knowledge, an NTC is simply decreasing the resistance once the temperature increases and increases the voltage that way (Fan spins faster).

So in easy words:
More heat = Faster fan (Less resistance, higher voltage)
Less heat = Slower fan (Higher resistance, low voltage)

 

Maybe, if I hadn't blown up a wall socket and electricuted myself as a child by sticking a pair of scissors into a radio electrical lead while holding a bulb on the end of the scissors,...

For the record the bulb did not light up...

 

Hahaha I think we all did similar things as child I personally messed primary with low-voltage stuff though so my brain didn't get roasted much xD

 

Are you two using Asus original graphics cards or have you succeeded in controlling fan speeds with custom cards? If so I am definitely interested in your VBIOS and BIOS combinations.

I am curious...

You cannot control the fan speed with a BIOS or the like you can only force the fans to 100% using RW Everything unless you intend to get your hands dirty with Hardware. I had a bad time with RWE so be cautious it is not worth the trouble and generated too much noise when a repaste will do more for your temps.

 

No, we don't have this issue with our G73jh laptops, only your laptop does this, so of course we don't have to "live with the fan noise". This laptop is easily the quietest laptop I've ever owned.

 

What's the graphics card?

 

This particular card was from Clevo, originating from a W860CU and reflashed with MSI VBIOS.

I have since then tested a 6970M from Clevo and with it the computer was finally silent. There is an other thread about this bsomewhere, stating that the circuitry, or some code or data in the VBIOS is needed by Asus to perform fan control. When the needed things aren't there, the fan control simply takes nothing for granted and cools "enough" for high load all the time.

So there is nothing magical about this - some cards will work, some won't and Asus has a business to run, rather than helping us with these things.

Case closed, so should the thread be too.

what program did you use to force fans to 100% i have just upgraded my g73jh to 7970m and i need a prigram to control the fan better fot testing

 

Hello yoshey791, congrats on your G73JH 7970m upgrade I always wanted to do that upgrade to my G73JH too but I don't have the tools and skills to perform that kind of mod (though I can only dismantle the beast for repasting CPU/GPU By the way, the software that we are using to force the two exhaust fans to 100% is RWEverything. There's a thread already that discussed how to force the fans using that software. It can be found here: http://forum.notebookreview.com/asus-gaming-notebook-forum/579780-how-force-g73-fans-100-a.html

 

so thats how yous have been getting max fans thanks.
well jehutyzeroshift if you can do a repast on a g73jh well thats the hardest part over by that i meen all those scrues and you have to take the whole thing apart just to change the ram and do a repast it wasnt that hard to do this upgrade to the 7970m i used the upgrade kit for a clevo w880cu. well the back part of the heatsink from the kit has been used. but after i finished the upgrade i seen that the msi 7970m heatsink would be better for the job and maby easer .... maby no cutting and just solder the copper part of the jh heatsink to the MSI heatsink. i think my gaming temps are to high 95c at the moment so im going to try a msi heatsink mod. i shell let yous know how it go's.
i was also wondering if anyone knows if the msi 7970m has fan control in the asus g73jh? and if enduro can be turned of in the msi 7970m vbios .

 

It's not a simple edit to disable the 7970M enduro setting, but you could maybe flash it with the Clevo/sager HM bios with the usual warnings of course.
