I'm worried, been playing Pes2008 for about an hour and rivatuner is showing 89dc! Mine is BFG OC version. I've not overclocked it and am new to rivatuner, how do i increase the fan speed?

Cheers Raven, set it to 50% using that guide and it came down pretty quickly to 76dc. Still seems high to me, is it? Really noticing the noise though!

My core clock shader domain is 1566.00MHz and rivatuner displays a warning sign, is this anything to be concerned about?

RavenXXX2 · 8 Nov 2007 at 00:32

Take no notice of the warning sign

Your temps are fine at under 80c, some people play with temps in the 90's so yours are fine, could always put the fan at 60% like me but if the sound is doing your head in, keep it as it is, IMO a wee bit of extra noise is worth it for a cooler running card.

On stock cooling mine hit 96c at one point during Crysis... now it barely reaches 45-46 overclocked with the S1+120mm fan.

Hey Raikiri, it would be great if you can post up some of those screenies for us all, I think this thread will be a useful reference for a lot of people interested in cooling their little demons!

I've learnt how to manually adjust the fan speed so far using RivaTuner but the 'method' for programming Riva to intelligently control the fan according to your personaly preferences looks akin to black magic! :eek:

Two guides have been posted so far in this thread so I will get my thinking cap on in a bit and try and sus it out. I think its way to fiddly TBH and I know that I am not the only person who will glaze over when confronted with that list of instructions!

Anyhow since I have basic *manual* control of the fan I am doing some testing using 20%/30%/40%/50%/60%/70%/80%/90%/100% fan speeds and will make some nice screenies to share with others.

If anyone who owns an 8800GT and has RivaTuner Installed can you please download this demo below and run it for 600000 ms (10 mins) and post a screenie* of Riva's hardware monitoring page (like the picture in the first post).

*ALT + Printscreen to grab just the active window rather than the whole desktop.

Thanks in advance!

Cmon *community*, drop your **** and grab your socks, I need some of you to run this test, doesn't really matter what res etc you set it at but add an extra 0 (zero) into the default time which will make it 10mins, run the test with Riva monitoring in the background and post a riva screeny up!

If you stretch the Riva temp window to the same *width* as mine that would be great, it will be roughly a 10minute timeline then.

Your efforts will be appreciated! :cool:

I just wouldn't be comfortable with a card hitting 95 degrees.

I wouldn't be too impressed having anything run at that temperature in my PC

Thanks for the Affirmation guys, it appears that I am not the only person who gets a bit *scratchy* when something is that toasty!

How anyone could even think of overclocking with temps like that at stock is beyond me :confused:

Hi,

When I've sold my 7800GT I shall be purchasing a 8800GT but going by the post I can see the temps being a problem in my case, could someone recommend a after market cooler that will offer cooling for the ram chips as well as the core?

Thx,
ManC

i'm not at all a fan of the 8800gt, in real use situations i think its basically no where near as superior as everyone seems to think it is. but case temps mean nothing in this case.

simply put, the temp of the core has NO bearing whatsoever on the case temp. you can have a 2W chip that runs at 150C, but still only pumps out 2W so will not heat up the case. likewise you can have a 250W chip that, because its a low voltage and literally, large die it runs nice a cool say at 50C, but being that the sink will be dumping 250W it will heat up the case.

the fact that the 8800gt runs hot physically, doesn't mean its got a massive power consumption. Its probably not that much lower power consumption than a gts, due to the higher clocks, higher shader clocks and higher tranny count. but in most situations it should run lower power, and basically, i can't name a case around that can't cool 200W of gfx cards and 150W of cpu with difficulty.... when talking basically any 120mm fan'd case from antec, thermaltake, coolermaster. case temps aren't an issue.

now the temps aren't fantastic, but it completely depends, if the chip is designed to still be able to run at 100C then its at 95% of its thermal rating, which is bad, if its designed to still run fine at 190C then its at 50% of its rating.

people just see temps as hot as really the only temps we ever think about on day to day usage throughout our entire lives is weather temps, body temp, water temps.

while with that temp, sure i probably wouldn't(ok i would) overclock, its not an issue for normal usage. nvidia aren't completely incompetant. they apparently did have some issues with single slot cooler, there was a big thing about weeks before release all of a sudden demanding a OEM box of dell and whoever else would sell the cards so they could test they would run fine in those boxes. if they still came out with single slot , well you can bet that they ran a little hotter in your bog standard oem case, then cases that 99% of us own.

It seems Nvidia decided to drop any kind of intelligent fan control on this one, so those temperatures may be nothing to worry about. My GTS ran at about 87 degrees with 100% fan speed, this one now does 84 degrees with 60-65% fan speed. This fan is damn noisy though, it gets annoying.
I'm almost done setting up rivatuner, will do the rest when i get home from school today, should hopefully get some results. Would wish i could just make it do 75% or something like that in all 3D applications, but 30% in Windows.
Will put the side of my case back on to see how much that decreases noise, but afraid that it'll keep all the air within the case, it's not the best case for airflow.

Realillusion222 · 8 Nov 2007 at 08:39

Mine was running really hot in Portal, around 90c. So I set up some fan profiles using RivaTuner, and whenever it goes above 60c, my fan speed now goes to 80%.

Now my temp never goes above 65c no matter what game I play

MystaEB · 8 Nov 2007 at 08:48

Mine has a picture of Vida Guerra on it - so mine's the hottest!

I wish.

Anywho, I got my BFG GT OC yesterday; from what little testing I did it seems to run quite warm, although no warmer than my old GTS. It was hitting around 80'C in both Hellgate and Crysis. It does idle a hell of a lot lower though, around 50-55'C compared to my GTS which would idle at like 65-70'C.

Not really worried about 80'C yet, and it's reasonable considering it lives in a SFF case. It's not technically an "ideal" temperature, but I doubt there is much danger to the card. I'll probably tinker with the fan settings tonight and perhaps give my case a good clean out to try drop the temps by a few degrees!

willhub · 8 Nov 2007 at 09:04

Up the fan to 60% and it'll drop to like 74 load overclocked, did for me.

R34pz · 8 Nov 2007 at 09:42

If anyone not able to stand the temperatures has got the guts to use an aftermarket cooler, I would highly recommend a Zalman VF900. Especially if you're limited for space and can't fit an S1 (even better) like Raikiri has. My idle temp is now 43, in games never reaches 60 except in the crysis demo, for what seems such a small heatsink it's fantastic.

Stock 8800GT Single Slot Cooler Reference Auto Temps

Made a bit of progress with RivaTuner and managed to get it to show me what the fan was doing when left on automatic. Up to this point I didn't think the fan was speeding up due to the high temps that the core was reaching under load.

When I first tried to get Rivatuner to display my Fan Cycle Duty it just gave me a reading of 100% all the time?. Anyway I read that I had to enable a plug-in to get this feature, by default it won't be displayed.

So got the rpms and fan% showing now and I increased the timeline to 20 minutes with a *FULL LOAD* applied to the card for 10mins using the program linked above.

I'm not sure if all 8800GT's have their fan controllers programmed the same but looking at bit closer at mine I am confronted by jargon that I don't understand? (lol nVidia stuff is different from ATI, what can I say!)

The first two and the last two I think I know but the middle three I'm not sure about?

T min ~ T range ~ T operating :confused:

By setting up your temperature limits/fan speeds correctly, the 30% would kick in when using Windows because the temperatures are far lower than whilst gaming.

My fan runs at 30% until the card trips 65 degrees, 50% when it trips 75 and 65% when it trips 85. World in Conflict, max details, 1600 x 1200, played for 3 hours straight did not trip the 65% fan and when the game is closed down, the temps reduce quickly and the lowest fan speed kicks in as my card idles at 55 degrees.

A bit of tweaking will get what you're after.

willhub · 8 Nov 2007 at 10:52

My fan never ever changed from 29% even in games, just stick to 29 unless drivers are causing problem?

Hi Will,

well I know where your coming from thinking that, I also thought the same however when I set the fan to a *fixed* 29% and ran the test I had a nasty suprise! :eek:

The first thing that happened was I could hear the fan trying to rev itself up to full speed while the test was in full flow, but because I had set Rivatuner to a *fixed* 29% the fan couldn't go any faster

EDIT: If there are any more nOObzoids out there like me then whatever you do don't fix your fanspeed any lower than 40% if your gonna be running 3D which I'm sure you are because this cards rocks!

Emlyn_Dewar · 8 Nov 2007 at 11:16

I thought when things are on a lower manufactuing process that higher temp was a bad thing? (Most likely nonsense, is it just higher volts that are the killer?)
I still wouldn't be happy, especially if I was having wayne's 108 degree fun... May be less convenient but I'd be looking for a bigger, better cooler. To hell with single slot!

Hyper · 8 Nov 2007 at 13:11

Mine is idling at 56C and have never checked during a game.

Yes 108°C is *officially* very hot!!!!!!!!

And then there was the smell, can't say what it was like but just think hot metal lol

Anyway the benchmark finished and nothing crashed!

If there are any more nOObzoids out there like me then whatever you do don't fix your fanspeed any lower than 40%. I have a set of results from running the fan from between 40% to 100% but I can't post all that now because I'm at work

Honestly mine aint set to fixed and it never revs itself up past 29%, at 29% my max temp in game is 89 degrees (in seega rally) taken from the OSD in Riviatuner on my Z10 display. At 60% Riviatuner was showing 74 degrees.
