Is it ok to run a Inno3D FX5800 at 72 C in 2D mode? This temp is according to the Nvidia control panel.

In 3D it runs at about 50C because the fan is on full blast. But I'm worried about the 2D temp.

If it is too high, I will probably add a Zalman cooler or have a pci slot fan blow on it. Thanks for the help.

couldnt you use coolbits and turn up the 3d GPU sped and that way the fan will be on faster?

The 3d GPU temp is fine...it's the 2D temp that I'm worried about. The fan is not on in 2D due to noise issues, so increasing the GPU clock in 2D will not help.

sorry about my last post nels, i meant to say 2d mode, but you answered that one too.

Not a problem..that's what I figured you meant. Thanks for the thought though.

72*c is a little warm... but its not in the 'Danger' area. As you say in 2D Mode the fan is turned off, and if you have a cramped/smaller case then it can get a bit warm.

You can try adding some more fans to your case (if you have that option), arranging cables to improve airflow etc... the Zalman coolers are designed to be 'quiet' rather than high-performance so i dont think it will help your temps at all.

The danger area for the NV3x GPU's is around 140*c i believe. Im also pretty certain the GPU's throttle back (in terms of Mhz and possibly voltage) when the temps get too high. The 3d fan would also kick in before that happens i would imagine.

Shouldnt worry. :)

Ehh.. Probably not much you can do, considering it's the 5800. Might want to try different placements with your cooling.

But in any event, 72 celcius is way to hot. I don't care what the GFFX can handle. That's fry an egg hot. Super Easy-Bake over hot. Keep a family of 10 immigrants warm in the winter hot.

It's using DDR2 & the R3xx isnt much better in terms of heat.... way of the world. :D

R3xx isn't much better?! No funking way. Your dreaming.

This is just estimating, but my Radeon 9500 (softmodded to 9700, and overclocked to 400mhz on the core) was around 30-40 degrees C at idle, and not much warmer at full load.

How do I know this?

At idle, the heatsink was *cool* to the touch. And under load, it was only barely hot.

There is no way the R3xx series gets as hot.

I doubt that the heatsink had good contact with the core then. I know that the early cards had a shim that prevented the HS to make good contact. A R3x0@400 MHz is a reactor. :D
I don't know how much you can trust the temp readings in the drivers, but mine idles at 62 d C and around 74 d C full at default speed (412/365).

As for the 5800. I guess the DDR-2 RAM heats up pretty much the whole card, so i wonder if it's a good idea that the fan stops completely in 2D. :p

When I turn the fan on normal in 2D the temperature drops to 50C. (To turn the fan off I flash it to a 5800 ultra bios I have) Do you guys/gals think that a Zalman will keep the core around 50C-55C in 2D?

I realize that I would need to put the optional fan on it too but I would run that fan in silent mode.

I've been running the core at 70-72C in 2D now for about a month and I haven't had any stability problems. I'm just wondering if it will be able to work at the temp for 2 years. The safe guard temp in the nvidia control panel is 140C...damn that's hot.

Well, the Zalman could possibly get you those temps.. But.. You would need more then fan blowing 10 CFM's on it.. You might have to live with those temps if you have chosen a silent life (without watercooling or Phase change). Especially if you are looking to get some performance (though, I wouldn't call the 5800 the best choice for performance) out of the box.

I could always recommend the useless advice to replace the card. Maybe a GF4 TI4200 would be more your pair (or something like the Radeon 9600).

I can live with the high temps if the card can :)

I got the fx5800 for $100 and it easily overclocks to a 5800 ultra speeds on the memory and GPU (500 core / 1000 memory) That is why i have it :)

I did think about selling the card and buying something else that would be quieter. The card has a radial fan that emits a high pitch noise when in 2D. I have sensitive ears and it drives me nuts.

I'm trying to find a quiet PCI fan to cool it in 2D. I bought the vantec spectrum one but it has 2 70MM fans spinning at 2400 RPM...it's too loud, but it keeps the temperature around 44C in 2D.

Modern video cards are completely responsible for global warming. My 5900u sits at 50C at idle and around 72C under full load.

Well I got it down to 62 at idle by just removing two of the pci slot covers below the nuclear reactor that is the fx5800.

I would like to add somthing like this, but i need to find a silent one.

I do like the FX series, cause I am stable at 70C on a 5600 for a laptop (freakin hot, but stable), with a laptop cooler, though its around 62-60.

I added a Antec Cyclone to one of the PCI slots, but it lower the temperature that much compared to just having the two empty PCI slots uncovered. Maybe 2-3C lower on the CPU and 5C on the GPU. Not enought to warrant the additional noise.

70°C is not a critical GPU temperature. Steve Simms (NVIDIA marketing) once said in an interview that GPU damage doesn't occur until 140°C.

That temperature is surprisingly high for 'idle' or '2d' operation. I have a 5800 normally running at 2D 300/600 3D 475/950 and it gets to 60-70deg range during 3D use and 40-55deg range during 2d. I have a couple of empty slots near it, extra drilled holes and 5x fans. The room temperature is usually kept below 30deg by air conditioner but last week got to 40deg (yes, outside record of 42degC for that day). To test stability, I managed to heat up the card to 90degC and ran it flawlessly for 12hours clocked at 480/980, with the hardest test programs I could find. I find the fan only goes to noisy mode above 80degC and it has done so by itself (without extreme testing) only twice in the last year (made me go 'whats that noise?'). Interesting cards these are, most people deny they even exist ;)

My 5800Ultra idles around 44degrees in 2d mode, in 3d mode running at 590/1170 it runs at around 73 Degrees, at 500/1000 it is running at 65 Degrees.

You don't have it overclocked running in 2d mode do you?
I have tended to find that it is the memory that causes the GPU to heat up as it shares the same heatsink. I also run a fan on the passive heatsink at the back of the card.

I'm unlucky as my Go chip has NO fan on it...

im runnin a 5800 NU and ive found my 2d temps are round 50-55 avg.. ive found the better the air circulation around the card (not just the case) it helps more, tis why i keep the side of me case off more these days during the warmer part of the year (im in australia :P)

Yes funking way ;)

This isnt estimating, this is looking at the temp readout on my 9800Xt. It can hit 67*c... or more at load. In a case with 5 fans... an fx 5950 reached a very low 45*c at load in the same PC.

Ur 9500 example isnt a good one either, the fact the heatsink is just cool to the touch most likley means its not making full contact with the core. On the other hand a HOT heatsink is a good sign - means its doing its job. Also remember that the heatsink is never going to be as hot as the actual core surface anyway, which is where the temp probe on the FX is...

I use one pump to pump chilled water through both video card and cpu ( coz it's cheaper of course ! ) and managed 11C on a 5700U and 17C for the cpu. The cpu suffers as it is second in line.

To be honest the 5700U doesn't get too hot anyway and is more hampered with lack of volts IMO.

My 5800 gets hot, but not really the gpu, more the DDR2 memory .. yeepers.
