7800go temperature fix...

Is there one? Now that I have your attention...

I started another thread on this because previous posts seemed to be scattered within other topics, and sometimes not even related to the 7800go itself...My main concern is idle temps when not playing a game, as the power required to generate this amount of heat obviously effects battery life...

First, some questions if anyone has any ideas...

-Does the chip by design not have the capabiity to run cooler? (lower voltage, lower clock speed, etc.)

-Is it not running cooler due to a driver or BIOS issue if it does have the capability?

-Can anyone report their battery life on a 9400/E1705 with either the onboard video or the ATI card? I see about 2.5 hours with the 9 cell...If people with the other cards are seeing the same then maybe it isn't drawing as much power as I think...

-Do other cards (ATI) run this hot, or maybe even draw as much power but seem to run cooler due to a different fan strategy?

-The latest A01 BIOS update shows:
2. Thermal control algorithm optimized for NVIDIA GeForce Go 7900 GS.
Could this be bad for the 7800, and are people still seeing high temps with the A00 BIOS?


Here's what I know about it so far...

-I have a revision II (according to Dell), and it idles between 65-75, depending on how long the fan has been on...Playing Oblivion shows temps in the 80s...

-I applied AS5 to it and it made no difference...

-I left the laptop apart after my AS5 application and the heat coming off of the heat sink was rediculous...I could barely even touch it...


I really like this card, but the heat that it generates when it is sitting around doing nothing seems to be very much on the hot side...Dell's fan strategy seems to be not to turn on until it's about melting, and then to cool it very slowly back to just hot...Good for battery life from the fan perspective I guess...

part of the problem is Dell has set the temperature limits in the bios to turn the fan onto slow at 75c and kill the fan at 65. only other way to get it to idle cooler is to change those settings. I9kfangui semi works, (infact a little better on the new A01 bios) if you lock the fans to "on". Thermal control is still too quirky as the program does not support Core Duo yet.
If dell has set it to 65-75 idle, then its acceptable to them, though I know some people out there would prefer a less toasty keyboard.

I don't understand why they don't let the fan on all the time or at least give the option to do that. Temps would be below 60C almost all the time. Now it goes from super hot to ok when the fans turn on. I don't like that especially that the fan is super silent anyway.

If you install coolbits there is an option to have fan always on in the control panel give that a shot.

I did thx but it has no effect. Fan still works like default. The option is in the "clock frequency settings" but even when ticked it doesn't do a thing.

You have an E1705, how about you try it and report back to us? Edit: nvm looks like it didnt work. I'm getting mine tomorrow, that POS better not overheat or it's going back.

I confirm that the 'fan always on' option in the nvidia control panel doesn't do a thing... but I applied AS5 everywhere, even the cpu, northbridge and the sponges thingies... my idle temp now is at 52 degrees... (i9kfangui fan always on..)

I've noticed on i9kfangui's site that is says not to use the fan control software for dual core processors?

Are you not worries it will stop the fan working and thus fry the card? Would like to try the software myself but am to worried about it failing

I have my 7800 running at 325/800 with no AS5 applied, and fangui set at both the CPU and GPU fans running on slow, and the temp on the GPU doesn't seem to idle any higher than 35 degrees most days. I also have my laptop sat on a Coolermaster 17" laptop cooler, but I wouldn't think it would make THAT big of a temp difference from your laptops. I don't understand why everyone else's 7800's run so much hotter than mine does? Are you folks using a laptop cooler as well?

considering that i9kfangui site hasn't had any sort of update since december, i fear we may never see a version compatible with our core duos... anyone know of any other software that does the same thing?


btw: any reason to flash the a01 bios? does it help at all?

I have a AT1400 and it does not get hot. the fans hardly ever turn on. If they do they are very low. Im on a 6 cell battery and I tell the comp & Video card to run at full speed when on battery and played WoW for 1 hour and 20 minutes before the low battery warning came up. Not bad for a X1400. Im impress what this little baby can do. It will never hang with the 7800 Go graphic wise but to me its the little engine that could. It plays my games without issues. Hope that helps. I have surf the web on it for about 2 hours and didnt pay attention how much more life. Now I dont know the temperatute on the ATi1400 havent found a program that will be able to read them. I will post temperature's once I find something that can.

This is one of the responses I was waiting for...If you get a chance to test your battery life without gaming, let us know...

Did you reinstall windows? If you are really seeing those temps and haven't reinstalled windows and/or a non dell driver, I wonder if that is our problem...

Has anyone checked the temps on a stock dell installation without changing the driver or reinstalling?

my installation was clean as I had a X1400 which ran really cool, usually in the 40's idle and 60's gaming...I was really un impressed when I installed the 7800 and saw the temps rise to 75c before the fans coming on then fall to 65, off then rise up again. gaming i seem to rise to the mid 80's. not unlike most people. AS5 will help it cool faster, but not keep the temps down. I have I9kfangui working stable with the fans locked on slow at all times and idle at 55-57c. These are just HOT cards. the 7900 series seem to be running a wee bit cooler from what i have seen, and they use alot less power, which probably explains this.

a Dell tech rep in Italy suggested speedfan.. he says this is what they want when you submit a problem regarding high temps... I downloaded and installed speedfan 4.28 but, for the life of me, I couldn't get it to change the fans speed at all.. I checked the Dell notebook checkbox, but got nothing out of it... I reinstalled i9kfangui and, with all its quirks, it is still able to turn on the fans (even if under high loads it dies on me switching the fans off..) as of now, I don't know of any other software that will do the trick, I'd like also to find something that works, because with the fans on you can really push the 7800 to its limits.. otherwise, it keeps overheating and falling back to lower speed, shutting down the 90W psu..

from what i've read online, AS5 takes about 200 hours of burn in time to properly lower the temps... that's why i have my 9400 always on even if I don't use it..

They will lower slightly (a few degrees C if you are lucky), but nothing drastic...

why do you say the Coolermaster doesn't help? I was actually considering buying one, how does it perform? Do you have any evidence of a cooler running note? Did you do any test? I'm really interested in this..

I'll take 83 over 88 any day.. this, plus anything the damn i9kfangui gives me (when it works) plus an eventual external cooler (I'm considering the Coolermaster notepal W1).. all together I hope to lower enough the temps so iI can play consistently at 430/950 (which I can't do now without overheating and shutting down the psu..)
