Hi

I have an HP Pavilion d4100 series PC with Nvidia Geforce 8800GT with 512Mb memory.
The thing is that the grafic card has a high core temperatur when it is idle, about 67-69 Celcius degrees. Is this normal?
The computer box has enough with space inside and the PC is well aired. I dont know if the PC box has enough with holes to give enough with coolage. The grafic card is not overclocked but in normal mode. Should i worry or not? If it is to hot is there anything I can do to lower the core temperatur?

Thanks in advance

Download and install [u][b]RivaTuner[/u][/b]

It allows you to take control of the low-level instructions for the cooling fan on the 8800GT.

By default, the 8800GT runs its fan at 25% rotational speed. Unfortunately, although this fan is 'supposed' to be temperature controlled, the accuracy of the control leaves rather a lot to be desired.

I had the same (almost identical) temperatures when the system was on idle, until I increased the fan speed to 80%. My 8800GT now had an idling temperature of 53'C and seldom rises above 61'C even when running CRYSIS @ 48fps.

There are instructions on the website but if you need any further help just post back with your details. :)

Did u use temperatur threshold for different fanspeeds? There is also soething about power user settings. I have version 190.38 of nvidia.

You'll get a little pop-up containing 5 icons - click on the icon to the extreme LEFT - it looks like a graphics card and gives you access to the low-level system settings.

The next window contains a slider for the fan speed.

TICK for '[b]Enable low-level fan control[/b]'.

Choose [b]FIXED[/b] (rather than Auto).

Move the slider to the RIGHT to increase the default fan speed - I leave mine on 80% constantly (I DID try using the 'Auto' option, fiddling with various temperature settings but it never seemed to make much difference - maybe my 8800GT's thermal sensor doesn't work with the fan).

But as I previously posted, it dropped my card's idling temperature from the very high 60s right down to the lower 50s, which can't be bad. :)

I have installed it and waited. The core temp is about 67-68 celsius degrees.
It didnt make big differens. is there anything else i can do? There is a option to change the coolage of the cpu on the grafic card. Its on 30 % for now. Should i increase it to a 60%?

by older mycroft

Thus, there is no way to increase the rotational speed or the temperature-response of the cooling fan(s).

All it lets you do is sit and helplessly read the current temperature. And it comes in an 85MB+ package - RivaTuner lets you vary the fan speed and occupies 2.5MB [i]period[/i].

I use the Precision Utility from EVGA, I have no complaints... my thermal temps are always great... you will have to sign up with EVGA, but its worth it... check it out http://www.evga.com/PRecision/

I take it you've already carried out this ludicrous practice at some previous time so's you know what you're talking about?

The bloke that advocating this had already overclocked his card - the OP hasn't OC'd anything.

You'll have noticed the 2 disclaimers in this article:

#1 [b]"..just make sure the fan isn't scraping along the graphics card/capacitor pins/whatever is under the card."[/b]

#2 [b]"(Pardon the crappiness of my MS Paint editing)"[/b]

[u]So it's actually only an imaginary project![/u]

[b]HOT GLUING[/b] onto the reverse side of a circuit board! That takes the biscuit. ;)

I done as u said and the core temp has dropped down. At 60 % fan speed the core is now down at 55 Celsius degees. This is a great result and i thank u as much as i can. However when windows restarts the settings i've made are gone. I suppose I have to save my settings? Do u know exactly what I need to save and use?

Thank u

by older mycroft

Never thought of it like that before, but I suppose it's a bit odd in the way that it works.

To the LEFT of the 'Save' button, there should be a little TICK BOX. It's title is:...
[b][u]'Apply fan settings at Windows startup'[/b][/u]
...that's what you need to tick.

[i]The 'Save' button is only to save the settings into RivaTuner (I think you can have multiple settings for different purposes).[/i]

Do I get my Thumb now ?? ;)
