Manual Control for G1S Fan

Is there any software one can use to manually step up the fan speeds on the G1S? I was running some benchmarks and, when the 8600M GT hit 102 Celsius the fan was still only working only at low/medium speed. That's kind of weird, to be honest...

 

I don't think so, since the fan is controlled by the Bios.

 

Make sure you have the most current bios?

 

There is no user-accessible fan control in any Asus notebook BIOS that I've ever heard of around here. More specifically, the fanspeed is generally tied to/depends on the CPU temp and not impacted by GPU temp at all, but it does vary and I'm not sure whether the G1 series has the latter engaged.

Speedfan worked in some of the much older units, and NHC worked to some extent in them as well, but neither of these is an option in current or last generation models afaik.

 

I suppose there is no way to modify the BIOS, right? Have to wait for ASUS to do something?

 

There are BIOS editors out there, but few know enough about how to use them (you screw up the tiniest bit, and your motherboard is a brick that will never ever come back).

Asus is highly unlikely to ever provide user control over fanspeed - too much liability for RMA when people mess up and set things incorrectly, then fry their components as a result.

 

Like what clearskies said, don't even attempt to edit your bios unless you know how to program a bios!
The best way for you to do is invest in a cooling pad and replace the GPU thermal paste with AS5 (only if you're brave enough and don't mind loosing your warranty )

 

Sigh. To get to the GPU I'd be needing to take apart a lot of things don't I? The cooling pad doesn't do that much because it can only cool the case... and indirectly the chip...

 

Not really... your notebook has vent located at the bottom. A cooler will blow air through those vents and directly cool the inside components.

 

Arg, that's annoying since I just installed Rivatuner with the attempt in controlling my fans and GPU temperatures... Is it only Asus that does this?

 

sorry guys, but for now forget the manual fan control over the G1S.

In my point of view it should be "ALMOST" possible since the fan has 4 connectors.

2 of them has always about 5.17 volts ,Black and Red, one of them has a variable voltage (if i recall well the orange) and that's what controls its speed and the other must be the RPM or a built-in temp sensor ????? (the white one), because i don't remember ever seeing a fan with 5V always connected to it unless they had a temp sensor (like some of the intel stock coolers). Well at least it should be possible the get it's value but for now no software read it, unless it's this value. (see image). Since i have an ES cpu i don't have separated core temps readings. Like i said it could be a temp sensor on the fan.

EDIT - AND Since the fan is inside the GPU cooler it is affected by the gpu temps, that white connector has to be a temp sensor on my point of view

 

I thought the GPU doesn't have its own fan? Seems like there's a heatpipe system that cools the GPU and CPU, and one single fan that cools the heatsinks attached...

 

I doubt the small slits that are cut into the bottom are large enough for external fans to force air IN though they are perhaps sufficient for internal fans to suck air in. The single internal fan creates low pressure fields inside the chassis that can only be alleviated by air flowing into the vents and hence forcing air in. On the other hand, it makes more sense for air that is blowing at the notebook from the bottom to simply flow around the case than into the vents... if you know what I mean. In any case, there are no such vents anywhere near the GPU, which is located at the center back..

 

you are right on the gpu position but the heat-pipe does a really really good job !! and since the GPU aluminum cooler that guides the cooper heat pipe is like 5 mm above the memory cover and it has holes on almost all the cover a cooling pad does send cool air to it. The only mistake from asus is the stock thermal paste that they use. If they used like mx-2 or at least as5 people would not be this unhappy. I have my 8600 OC to basically what it can give and my max temp is around 90. it fluctuates between 88 and 90. Only on really hot days it MAY go till 92 and it depends on the game, grid puts it at 90º after a couple of hours of playing but CSS puts it at 80º, but like i said i have it OC. So i presume that if i only used the stock clocks the MAX temps would be around 83-85º with grid or maybe less!!

My opinion sticks. The laptop manufacturers insists on putting CRAP thermal paste and that , most probably, is why so much laptops overheats and burns.

A person like me, that is careful on checking dust once in a while probably would "never" have a single problem with overheating but the main problem remains. The thermal paste they apply on assembly.

That's my verdict on the G1S / G2S and probably a bunch more of laptops out there like for e.g the acer 5920. Same problem, crap thermal paste. Exchange the "concrete" thermal paste like the asus one and voilá, 93º with a hell of a OC on the 8600.

 

I would have to disassemble everything and void the warranty if I were to replace the thermal paste, wouldn't I?

 

Yep, that's correct.

 

technically yes !! unless you know how to preserve the warranty stickers and use gloves and the proper tools.. But yes, if you mess anything you will lose your warranty

 

i don't know

i hope other guy help you

 

does NHC not work with the G1? It has fan control and with a little tweaking I got it to let me have full control of my a8js fan.

 

What sort of tweaking did you use?

 

Last I knew about it, NHC hadn't been updated for Santa Rosa or more recent... so unless things changed (the date of the latest release should tell you whether they have) I wouldn't recommend it for the G1S.

 

I'm with him all the way !! it's anounced on the site a new version soon... we just have to wait for it

 

Hopefully the new one will let us ramp the fan up to max... The heat dissipation design is terrible in the G1S, I mean, why let the CPU temperature control the amount of cooling the GPU gets? :S

 

Standard for the industry. Asus can code one BIOS to the model motherboard, but doesn't have to come up or update the mb BIOS for every single gpu that gets put into a model over time during that series' life run.

Economy of scale.....
