Howdy.

So I just installed an EVGA 8800GTS 640. Everything is running great, and the increase in power is immediately noticeable in game. I love it.

I'm using Riva 2.03 to put a slight overclock on it. In the diagnostics, I'm noticing that the video card fan is only at 60% duty cycle. During gameplay, the gpu gets up to about 80 degrees C, which isn't critical or anything, but I'd like to see it running a little cooler.

Is there a way to manually increase the fan to 100%? Or better yet, is there a way to set a temperature threshold to where the fan would automatically kick in?

thanks.

Okay, so I just found in Riva the low-level fan control settings. I can see the fan control rules, but I don't seem to be able to modify them. So far all I can do is manually adjust the fixed fan speed (which may be all I need).

But I'd still like to be able to set temp thresholds for the fan control. Who knows, maybe in another 15 minutes I'll be able to answer my own question again. :o

You have to hit "apply" before you hit save.

Yeah, tick the little box next to Apply to the left of the Save button, then the Save button will become active.

Thank you!! I had looked through the readme included with Riva, but there was nothing like this in there. This is perfect.

Sorry for hijacking the thread, but is it safe for the fan to be 100% constantly?

Yes but there's really no reason for it.

thanks, but I may have to run it at 100% always, its quite hot at our place. Its idling at 55c @100% fans speed :(
