Rivatuner 2.08 on 8800

Looks like this thing can override the card BIOS, and
control fan speed settings depending on threshold temps.
For example, it runs the fan at 60% at a selected temp
.... say 60 C ... and then will run it at 80% when the
temp reaches ?? .. say 80 C ... and then 100% when
the temp reaches ?? .. maybe 90 C or 100 C.

I'm looking at this wondering if I can set the fan speed
at just under the audible speed ?? maybe 1200 rpm
and leave it there all the time. Reason is I want the
dang thing to quieten down and quit whistling when
the game gets going. What I notice about the card
BIOS setting is the 60 % rpm is about 625 rpm.
That is too slow, and allows the card to heat up
before the fan speed comes up. If I run the thing
at 1200 rpm all the time, until the temp hits a
much higher level, and then up the rpm, I might get
much longer quiet times.

I tried 2nd source fans like the Zalman, and they
don't work on the 8800s any better than the stock
fan .. plus they have to run at a constant speed, so
I can't profile control them ... unless somehow Riva
Tuner can see them ??

Any third party fans can be controlled by a dedicated fan controller
that sits in one of your 5-1/2" bays. I think Thermaltake has one with
lots of inputs. I most often saw this recommended with the DuOrb that's
so hard to find now.

Messing with fan speeds really isn't a great idea if you can get a
replacement BIOS from your vendor. I know this was a problem with the
first run 8800GT's, but for example, most vendors like EVGA and XFX have
released updated BIOSes by request that set your duty cycle to
recommended speeds.

Mine for example is a 2nd production run 8800GT and comes with a
slightly better HSF and a duty cycle of 40%. I have decent case
ventilation, so my GPU temp never exceeds 65C even under load.

Anything around 60-75C is really nothing to worry about and is in fact
by design and normal for the chip. I'd get worried if it was that hot
at idle though.

Mine idles at 65 C, and goes to 83 ingame. Not bad,
but still noisy. I called BFG, and they said my card
has the new BIOS. Only problem is the crappy fan.
I tried a Zalman VF 900, and after I solved the tape
issues, I got it to work, but it was no better. I actually
got better results with the stock cooler, and a side
fan on the case door ( Antec 900 case ). I don't think
the fast fan is doing anything except making noise.
Makes me wonder if Riva Tuner might be able to
show me that. I just don't trust the install to clear
out if it fails to work. Unless some of you out there
have tested it. I'm running the 169 driver, and I
remember some squawk about Riva Tuner not
working with that driver ?? Maybe an older version
of Riva Tuner ?? and the 2.08 does ??

I am using RivaTuner 2.06 on Vista 64 to control the fan speeds on my
Gigabyte 8800GTS (G92) 512mb card. This card was running 70deg idle and
about 90deg load on stock fan settings and would crash in games. I looked
for an updated bios and found nothing so I started using low level fan
control though rivatuner and it has worked a treat. The fan is at about 40%
and 55deg for idle and never gets much above 70deg for games. I would say go
for it as all the changes are software level (nothing is actually done to
the card) so you have nothing to lose, and low temperatures to gain.

What were your settings ? I would like to quieten
this thing as much as possible. If I could find a
single setting that was quiet, but held the temp
down, I would like to do that. This BFG card is
a G92 chipset, so it should run much cooler
than it does without having to crank that stupid
fan to 100%. It is a screaming hell-raiser at that
point.

GT or GTS???

My settings, applied through "Low-Level System Settings" are as follows.

Auto Fan Speed Control Rule
Duty cycle min 40
Duty cycle max 100
T min 50
T range 32
T operating 70
T low limit 0
T high limit 90

as a comparison the default values are

Auto Fan Speed Control Rule
Duty cycle min 36
Duty cycle max 100
T min 65
T range 32
T operating 83
T low limit 73
T high limit 93

I have this saved as a fan profile which is set to start on windows startup.
To change the values above you need to go to the Power User tab, go down to
"RivaTuner \ Fan" and change the value for AutoFanSpeedControl to 3. To get
mine to start everytime (on vista 64) most of the normal autostart options
didnt seem to work, but saving the settings as a fan profile, and setting
the fan profile to start at a certain temperature seemed to work. I am not
an expert in this by any means and most of what i did was patched together
after reading some guides on how to use rivatuner on the net. One guide
showed how to set these numbers and gave a set of recommended values which i
have then fiddled with to get working how I like (not sure exactly what
changes what). As a note I live in Brisbane, Australia in a room without
airconditioning that is generally rather hot (and I set this up during
summer) so you could likely set it up for lower temperatures and fan noise
in your own system.

Card is a BFG GF 8800 GT Overclock ... basically a GT
that has been overclocked. Properties list it as a GT, and
I'm sure that's all it really is.
