8800gt fan control issues

Hi
I've got a bfg 8800gt oc @ 625mhz and 900mhz. I'm able to control the fan speed with rivatuner, except when the temperature reaches (about) 107 C. It seems like some safety functions takes over and kicks the fan to 100% no matter what the settings are in rivatuner. Does anyone know of any alternatives to rivatuner that could help? Would flashing the card help?

nTune doesn't do much good, btw. Can't adjust fan speeds.

System:
CPU: E2180@ 2.9ghz (stock voltage)
MB: ASUS P5E-VM HDMI Socket775 mATX
Case: Antec fusion v2
OS: Windows XP


Thx.

Uh how long have you been running like this??? Because your card is probably partially damaged. 107C is EXTREMELY HOT!!! How many fans do you have in your case and what size are they??? Also, what is the ambient (room) temperature???

wow that is really hot. See if ATI tray tools works with a nvidia card, don't know though.

Yeah your card should not be getting even close to 107C, my 8800GT ran at 60% fan speed and never broke 60-62C. Either your fan is broken or your card is broken or it's 150 degrees in your house.

Okay, so maybe I should just accept ~107 is maximum and try to adjust the fan setting to keep it below that.

Well... There are two 120mm fans, but one of them is turned off and the other one is running on low.
I'm not sure it would help much though. The graphics card has the fan turned away from the rest of the case and is squeezed into the corner of the case. There is a single (unused) pci-e slot next to it and then metal.

I'm guessing the temp is around 30 C around the case.

So, let me get this, you do not like the fact that no matter what your GPU fan hits 100% when your GPU hits about over 100C?

Try putting a PCI slot cooler below it is all I can think of.

You should have both fans running at least on Med. That's probably your problem. And no you should not accept 107C as your max temp that's WAY too high. 70-80C maybe. I think your problem is the airflow. I have an Antec 900 and all 5 (4 120mm & 1 200mm) fans are on high to keep my highly overclocked HD 4870 (820/1145) running @ 46c idle and 55c load w/fan speed @ 45%.

They are just a bit to load even at med, so I'd have to manually open the case to adjust the speeds when gaming. Guess I'll have to look for new fans. Any recommendations?

Yes

ok these guys are stupid just put a PCI fan on the expansion slot ABOVE your video card.

and these are the thermal specs for G92:

80-90 is average
115 threshhold
127 burnout


nibitor is also good for tweaking your fan speeds to your own personal taste

Hey bpogdowz, I don't know where you get your information, but 80-90C is not average. I have a heavily OCed 4870 (830/1170) which, if you didn't already know, is one of the hottest running cards besides the 4850. I don't have some PCI cooler on mine and its loads do not exceed 55C. That's due to good airflow in my case not a PCI cooler. Read any suggestions on how many fans to have in any given GAMING case and they'll tell you to have at least 2 120mm fans.

As for you Draskrabbe, here's a couple of nice fans that I looked up for you so tell me what you think:

That one's very nice. Has a speed control and evrything
http://www.newegg.com/Product/Product.aspx?Item=N82E168...
That one's a little expensive but has a lot of good reviews
http://www.newegg.com/Product/Product.aspx?Item=N82E168...
That one's quite a bit louder than the rest but move a ton of air



P.S. bpogdowz: just because we have different opinions than you doesn't mean we're stupid.

+1 ibuypower. great suggestions. OP you really do need good air flow though your case, one 120mm at low settings is not enough. i have on 120mm in my case runing max all the time and i usualy idle around 50-55c on my graphics card, and the card i have should run cooler than the 4870. is one of these cases yours OP? http://www.newegg.com/Product/ProductList.aspx?Submit=E...
if so you defiantly need to run both fans. these kind of cases are not made for gaming and will run hot.
one more question for you. when you game do you use headphones or speakers? the reason i ask is cause i use head phones and i cant really hear the fans in my case. not enough to bother me.

Thanks for all the help.


My case is this one, which have two Antec TriCool:
http://www.silentpcreview.com/article591-page3.html

As you can see, the graphics card has to be located at the upper left corner of the case. The fan is pointed to the left right into the side of the psu, and since it is a single slot it blows the air right back into the case.
Getting a fan cooler is actually not a bad idea. Anyone that can recommend a rear exhaust pci fan?

I really, really have to get a dual slot cooler for next graphics card. Is it possible to get graphics cards with the gpu and cooler on the other side?

The graphics card seems to be steady around 55-60% fan and 100 C, which is hot.... But winter is coming anyway :) .

100% is very loud, even with headphones. 55-60% is doable with headphones. Also it is being used as a media center, so it is very important that any other fans are able to quite down when idle (right now harddrives are the primary noise source when in idle).

ok now i got one more question, is the card always running that hot? what i mean is when you turn the computer on and it boots into windows is it running at 100c? or is more like 75-80c and it gets hotter and hotter till it reaches the 100c+.
October 23, 2008 2:02:20 AM

I think in your case that bpogdowz is right. You need a PCI type cooler to go directly behind your card to exhaust the hot air coming out of your card. I think that would be the cheapest and easiest solution for you.
October 23, 2008 8:02:49 AM

@ilovebarny
If I don't game it runs at around 60-70 C with the fan at 30%.

@ibuypower
There is no room behind the card, only next to it. And all the pci fans I can find face the wrong direction (away from the card).
October 23, 2008 10:27:56 AM

the fan takes in air through the blades and sends it out through the vents on the bracket and you can turn the fan over if you need it to suck from a different direction: http://www.newegg.com/Product/Product.aspx?Item=N82E168...

the reason why you want the fan above the video card on the expansion port is because hot air rises. so flip the fan so the air is sucking air from below that's above the video card taking hot air right from the PCB and out through the vents on the expansion port bracket and out of the case away from your other components.
October 23, 2008 6:14:03 PM

ok then its your case. you just need better air flow through your case. i dont know if a fan like the one bpogdowz suggested will help a whole lot, but it will help.
October 23, 2008 10:33:30 PM

See with your card, it pulls in air and then exhausts it but not out the back of the case. In your situation, the hot air being exhausted out of your card is then being drawn right back into your card.

You need a small fan to take that hot air out of your case as soon as it leaves the heat sink on your card.

no its the other way around
