Hi,
I just got my 8800GT yesterday & I want to give it a few days to settle in before I start my OCing tests. However, the first thing I noticed when swapping out my [eVGA] 7900GT KO (580/1580MHz) for my new [eVGA] 8800GT Stock (bulk, actually...) was that the fan's RPM doesn't noticably change when going from 2D to 3D apps like the 7900GT did.
Using nVidia-nTune's Monitor app, I noted that the fan is automatically at 29% when the system's idle. If I manually go to 50% or higher, it's easy to hear the fan (@100% it sounds like a jet engine, lol).
So I'm quite nervous about the fact that while playing Crysis @1680x1050 (w/everything on high) that I don't hear the fan's whine...
I noticed in another thread someone posted their 8800GT's idle temp:
Furthermore, the GPU'S idle temps, as reported by nVidia's Monitor app, are substantially higher than the figures you lads are quoting here. My 7900GT was idling at around 60C, and the 880GT idles even higher at 66C... .
nVidia's Monitor app also has the ability to log temps (as well as core/memory speeds and CPU, Memory & HDD utilization, etc.) to a file. So I logged a 3DMark06 run with both GPUs and the 7900GT hit 98C and the 8800GT maxed out at 91C.
There's an indication that the fan is speeding up a little, though, 'cause the temps always shortly peak immediately after I stop a benchmark. This suggests that the fan is immediately lowered to that 29% (although the GPU is still hot).
Looong story short, do you guys note a difference in the fan's speed (i.e. hear the difference) as soon as you shift into 3D?
btw, I logged temps during normal gaming and reached the amazing temp of 104C with my 7900GT (nope, not kidding) - and, before you gasp, I've been gaming for over a year at approx. the same temp without so much a blue screen or artifacting. Playing Crysis last night for two hours, the 8800GT didn't break past a peak of 94C which again, makes me think that the fan RPM does increase, just not by any "audiable" amount.
Here's a sample of the log:
Current Time/ Gpu core(3D)(MHz)/ GPU memory(MHz)/ GPU1(ºC)/ CPU(%)/ Disk(%)/ Network(%)/ Memory(%):
2007/12/4 23:25:56 601.0 900.0 74 5 % 45 % 0 % 19 %
2007/12/4 23:35:36 601.0 900.0 94 72 % 0 % 0 % 63 %
As you can tell by the timestamps, I pasted a pre-gaming and in-gaming sample.
Specs are in my sig. Case is a Thermaltake Armor which houses 2x120mm and 2x90mm fans. An external probe inserted into the 8800GT's HSF exhaust opening recorded 49.5C idle and 62C during 3DMark06 (peak). Ambient room temp during all above measurements was 21-22C.

You should definitely look into buy an aftermarket cooler such as AC Accelero S1. Or you can simply download Riva Tuner and manually change the fan speed to like 60 or something if you don't mind the noise. But even so the idling and loading temp of the 8800GT still won't drop due to the cheap heatsink that nVidia slaps on this monster.
This is my rig.
