Question:
7800 go drastic overheating - Dell replaced for 7900
HI,
I have dell 9400 with 7800 go card. When I got the laptop the idle temps were around 60 and during gameplay up to about 80 until fans kick in then back down.
NOW - it idle at 75 and that is only if I set fan control to force both fans high speed. Or it climbs into the 80's
If I play a game it goes into the 90's!!! surely this is too high.
I dont understand how this has suddenly happened it never use to get up to these temps.
I was using 81.97 mobileforce drivers then went back to stock but it has not helped. Also this temps are with the card at stock settings not overclocked.
Please any help or assistance.

have you checked for heavy dust buildup or blocked vents?

ditto for dust

sounds like blockage to me as well, be it dust or other wise.

What fan program are you using? If you are using I8kfangui are you sure you are not reading the peak values as opposed to the realtime values.

Hi,
Thanks for the quick responses. Ive had a look into the vents and can see no dust or blockage I have sprayed a little compressed air in but nothing seemed to change.
I am ensuring that there is plenty of airflow around the laptop also.
I am using I8kfangui and it is realtime and i have adjusted it for the error and the temp now matches what it does in the nvidia graphics utility.
And when I came out of a game it peaked at 93, which is the temperature the core automatically down speeds itself.
Like I said all is the same setup it was a few months ago and my temp readings were 15-20 degress lower and never went above the low 80's even during heavy gameplay.
Any more ideas suggestions?
someone suggested getting a hover tube next to the vent and trying to suck out dust or blockage, Im not 100% happy with this idea but maybe its worth a try as long as it wont damage anything.

I was having the same problem not that high though. It was hot for the computer to touch my leg through blue jeans. I changed the 7800 for a 7900gs it seems to have helped in some respects. Mine never got as hot as yours though I would have gotten them to take it back. But I can say this overclocked my 7900 GS is not near as hot feeling as the 7800 not overclocked. My problem now is it seems like the fans do not want to stay blowing they cut on then right off then back on again. Which is strange since they never used to come on until I got the I8kfangui. They only came on low if at all. I am obviously not telling you to do anything just stating a fact that the 7800 is very hot and they seem to not have very good fans. :confused: My Asus blows hot air all the time but atleast I know it works without sounding like it is dieing. I really wonder if there was a flaw in the first few batches of E1705/9400. Mine is several months old. I am considering a fan change or something that can get the temps down. My processor is not overclocked and never has been but it is getting hot enough to fry eggs. It is actually getting hotter than the GPU if the fans are not on. What adjustment for temps are you talking about with I8kfangui?:confused:

if you have never taken care of the dust inside of your notebook, then you need to open it up. it's probably compacted enough that simply blowing air into the vents isn't doing any good.

I understand dust I live in the desert. But if there is no dust then what? My fans sound like they are dieing. That is when they are on full speed. I changed the video card and that has helped with the heat. Without I8kfangui I get only low fan speed ever even when the thing had the 7800 and was so hot I could not stand it on my leg. No there was no OC. Now it is reasonably cool. With the 7900 gs temps only get high when OC and no high speed fans? I am just curious about this is why I am asking.:confused:

If the fans are dying, then you should contact Dell.
I would suggest getting a cooling pad regardless . . check our Accessories forum.
