i'm running a 6800gt PCi-E card.
what is seen to be acceptable levels of
temperature for the card?
after intense use for about 1-1.5 hrs the temp seems to hover round the early 70 (dgrs c)
is this reasonable? and can putting just an extra fan onto the mobo blowing directly on it doing any worthwhile improvements?
any thoughts greatly appreciated...
-
I have the AGP slot 6800gt and same goes for mine under load, 71 degrees C.
-
my 6800gt 350/1000 probably runs about 5-10c less, but i have three vent fans, 120mm in the psu,the80mm case fan and a pci slot extraction fan.
I doubt the temp your card is at is any problem but if you cool down the case by a few degs then the card should be a little cooler.

your okay I have a 6800gt OC BFG
and at idle i run at 58C and full load at 68C
I had to send my first card back to BFG because it was faulty talked to there Tech Guy and he told me that they can get as hot as 90c with load and he told me that was still good.But the first one i had at idle it was at 70c so I knew
I had trouble then and then it burned up and i sent it back and they sent me a new one
-
The 6800gt OC BFG is the card I am interested in acquiring soon. It has two fans so its temp ought to be better than stock. Sorry to hear about your problem. I trust their support was good? They have a trusted name.
TactS!

It was great!!!They did`nt even hesitate to send me another one I freaked out when he told me under load 90c!!!(as high)No prblems with other card they sent me I`m real happy with it
I putt a new power supplie in 600Watter I think its bad getting Voltsge spikes on my reading`s
should of listen to Lucky on brand I bought a MGE PSU

my bfg 6800 gt oc is great...i dominate in call of duty...and i get dominated in IL2 and PF...but thats not my cards fault...my temps are 55 and 71...and i have mine oc to 390\1100...its a good card just keep your case cool...yeah the 2 fans are really no better than one...but they work just fine and they have a wicked blue led light...matches my case mod nicely...

Forgot to mention that I'm OCing mine to 400mhz 1010mhz with stock cooling, the tower has no fans in it except the power supplies and the cpu's and the vid cards, but I do keep the side off the tower

I have the 6800GTOCd256 too... I get crashes from it often..... http://forums.ubi.com/images/smilies...smiley-sad.gif I have 2 fans on my PS, one 20mm on the side and one in the front sucking in and one in the back blowing out plus a pci slot fan as well.. still it gives me the herringbone graphics glitch...... I am going to try taking my case off or getting a better fan.

Does this happen in any game mate? Sounds like overheating but you seem to have adequate ventilation. Your heatsink is functioning properly, right?

I was surprised to see people even as PC smart as Bela say things like, the GT doesn't use much power. I want you guys to think about this for a minute...
What physical force is acting on the board to heat it?
Answer is = electron flow measured in watts of power!
You gottum other answer, I'd love to hear it from you paleface! To say a board heats, but uses little power is complete and utter nonsense. If a power supply can't give the necessary wattage at a certain voltage, it will try to make it up in amps. Remember, amps X volts = watts. It's simple math and no belief system will overcome math. If the wattage can't be delivered at a certain voltage by the power supply, it will try to make it up in amperage. Being fed too many amps at a lower voltage VS. less amps at higher voltage to give the needed wattage = power to run the board, causes the card to heat beyond its designed limits.
I am NOT, repeat, NOT saying that this is the only or the most important concern in all matters. You still have to attend to case cooling and cooling of the card itself under even the best of power deliveries.
However, believing your heating situations don't have a power component to them is just that, a belief system.

Talking of paleface...
Hey HEY! In the context I told that, it was in comparison to the older nvidia 5900 series wich many have been using for more than 2 years with much less suited PSUs (for a laugh, my old one would recommend a 250W on it's box). Power consumption in a GT is around 55W while 5900 ultras and 5950 are in the 60-80W and up range as with 6800 ultras.
When compared to people running old 4200's or 9500 it's quite a huge step, but not compared with the last 2 years's top end, as most here came from 9800s. These had similar power consumption, but WAY less transistors and less core area, less power regulation on mosfets due to bigger processing needing more v, and hence less heat directly on core and pcb. Still, the strain on the psu was the same and where running (supposedly) fine. That was what I meant in other post, everyone knows 6800s are power hogs no matter what, so please take that comment with a grain of salt. http://forums.ubi.com/groupee_common.../icon_wink.gif

No worries Bela, you forget more about computers in a day than I will probably learn in a lifetime!
Still, you take even the PCI Express versions of the 6600 cards for example... Watts of electrical power used get expressed in light, electro-mechanical motion like fan motors or heat. This directly translates into a certain amount of calories of heat. The calories of heat being produced by even the 6600 cards shows the manufacturers are under-reporting the actual power usage of the boards in question or the temps would be lower, especially with the heat sinks and fans carrying away the heat. I do not know if the manufacturers under-reporting the power consumption needs of the parts in question is willfull or just a mistake, but I suspect the former.
You bring up another excellent point about PCI Express. They get all their power through the PCI buss and as a result, are limited by whatever power your particular MOSFET/motherboard power circuitry setup can deliver. At this point, I doubt the boards are truly up to giving rock steady performance, especially in dual card modes. Trying to beat the information out of the motherboard manufacturer as to how well their part will deliver the needed power saturation to the PCI buss seems next to impossible right now. I predict a whole series of picky, transient power related failures for most of the boards being produced today. First the gamers will have to wake up to what is happening and then pressure will have to be put on the manufacturers by the consumer before this problem ever gets fixed, so you guessed it, a 1-2 year process if it ever gets fixed at all.
Ah yes, I pray for the day that motherboards will be sold based on their specifications vs. cool names! http://forums.ubi.com/images/smilies/blink.gif

Are you saying that Mobo's are power starved at present, or that they will be in the near future?
-
Sorry for the OT on the temps, but following the last 2 posts:
Every mobo is starved right on boot up http://forums.ubi.com/images/smilies/1072.gif , this is where it draws almost infinite current from your psu and all components are filling those caps etc, even tough it's for a very short period it gives a lot of strain because the psu hasn't time to stabilize.
As an example, probably the most extreme mobo around is the dfi nf4, where IIRC they state a 94a peak on 12v right on boot up http://forums.ubi.com/groupee_common...s/icon_eek.gif. People are having a lot of trouble with old psus on it or even small rated dual rail ones where the cpu line is rated less than 20a, and some brand 430w can't even make it boot up. Just go to dfi-street.com and see how many long threads about PSUs you can find in there!
For PCIe starvation, well, cards are going the old route again, current PCIe monsters already need extra plugs. The aforementioned board needs an extra molex plugged to it, the 24 pin, the 4 pin, and even a small fd power plug (and I guess something more that I'm forgetting right now!). With many "weaker" but equal power sources around , it's easier to make them more stable across the whole board. Currently it's working pretty fine given the crazy clocks people are getting on it.
LB, for power rating, manufacturers should make requirements from all the power a component draws right on the plugs or sockets, not matter if chips use it, or it's dissipated on a power regulation section. Still, drawing a lot of 12v to dissipate on a 1.x v feed is a huge waste. Add this to less than optimal PSU efficiency, under light load most PSUs are about 60% efficient and the best ones (you'd be surprised on how many brand psus would do less than 70% on older models) will be at most 80% on full load which is a big waste too.
