What are the max temps you would recommend? It says the slowdown threshold is 130 degrees C, but I don't know how much to trust that or how close I would want to be to that.

The card is a fanless heat pipe design, which was fine when case fans were running. Now the machine is being silenced via water cooling, but I'm not sure if the VGA adapter will fit on the card or not because the original heat sink was fanless, so am trying to save the VGA adapter to sell if it isn't necessary.

Now without case fans running, the card idles at 88-90 C and under load (5 min 3dMark 06, currently stressing for longer) goes up to 103 C. Is this okay?

I'm no computer expert, but I think that would be really bad.  I can't imagine having a piece of metal at the boiling temperature of water is a good thing.  I'd get a fan or your VGA adapter on that baby ASAP.

After a more stress testing, it got up to 117.

That's bad.

Do you mean a 7950 GX2 or 7900 GTX?

7950, I thought it was GTX not GX2, but it is the card that is basically two 7900s in one.

117, dam thats hot...

I wouldn't want to run anything over like 70-80 Under load... But then again, I know nothing about computers.

So presumably you mean the 7950 GX2. ?!?
I don't have one of those, but if my 7900 GTX ever gets hotter than around 60 then I start to worry, and have configured a case fan to start pumping more air through the case. So if you run between 100 and 130 degrees celcius on your 7950 GX2, then I'd wonder where the F you want to put the excess heat, because you'd BETTER have very good airflow in your case to get rid of THAT kind of heat. I mean for christss sake, you can bake bread at those temps !!!! And your board will NOT like working in temps in excess of 50 C. So do NOT push your GPU to 100+ C unless you have somewhere to put the extra heat.
Now a 10-20 degree increase in heat output when going from idle to active is not uncommon. But a 90 degree idle that's just way too much.

i´ve heard, that the lifetime of an electronic chip decreases rapidly, when heated over 70°c. but the nvidia gpus can be heated up to 130°c.

i think, it would be better to cool it down a little, because the temperature shown on screen isn´t always the real temperature. and i don´t think, it´s
too healthy, if your card heats up other parts in your system.

You should get this

I'm not sure how well it works, but google led the way.

lol. Read the OP, I'm doing water cooling, there is no airflow or case fans. Nothing else in the computer gets over 55 C at any load.

That is the exact card, my bad, no GTX just GT.

Why can't you just buy a water block for your card?

I possibly have a water block, but I'm not sure if it fits. Basically I will if these temps are too high, but technically it's over 10 C away from the slowdown threshold...?

Anything over 80c is bad, anything over the boiling point of water is not good at all.
I would just install a water block.

I'd suggest that you'd be better to install the water cooling too. Even if thise temps are within spec, you should have better performance with lower temps. Plus your card will last longer - temps that high (even if within spec) will wear out your GPU faster.

I have a 7900 overclocked to 7950 speeds, and I've never seen it get above 65C.  And my bonus room gets really hot in the summer (like 85F sometimes...).  That's really hot..

EDIT:  it's fanless??

http://www.newegg.com/Product/Product.a … 6835114024

get one of those, I have one for my 7900gt, and it has a fan on it.  It really keeps the temps down

The biggest problem is I don't know if the heatsinks are compatible between the fanless and the ones with a fan. If they're identical, my waterblock should fit. I think I'll try the waterblock on to see if it will fit, if nothing else to lengthen life expectancy as stated.

Oh, and you can't really overclock to 7950 speeds, the whole point of the card is doubling the memory.

I see.. then I suppose it's just a lousy overclocked 7900 gt... *sigh*

anywho, I'm confused.  The fan I showed you was something you stick in a PCI slot below your card to blow air onto it.  And you do realize you need a water cooling kit with your waterblock right?.. you can't just stick it on there/

I think from his original post he has made his whole system fanless. So now there's no airflow to take the heat away from the heatpipe on the video card.

Fanless is a nice idea, but for performance machines it's probably not suitable. Some slot coolers are fairly quiet, so maybe you could just use one for the area under the video card if the water cooling won't fit.

Still, I didn't say that you should change to air cooling, I was just commenting on how I manage my 7900 card. But if your card is hitting 100+ then you 'll STILL want to redirect the heat. You MAY or may not have an external reservoir or radiator, but if the water in your system isn't cooling down enough to cool your card below 70, then your cooling system is WAY inadequate, or you're WAY overclocking. In either event, you'll STILL want to redirect the excess heat AWAY from your system, and in particularly away from your GPU. Also, if you've only got one string on your water cooling solution, and you run the water from your GPU to your CPU, imagine how hard it will be for the CPU to cool down ! If you're doing it vice versa, then maybe your CPU is too hot for your cooling block.
Water cooling is nice, but it's NOT something you can just slam into any PC and it'll work just fine. majority of "complete systems" are desgined for low end PCs. The high end systems are hard to come by and obscenely expensive, or you have to build it yourself. In either case, 100 degrees C is way too much for your card, and while it's not dead yet, you'll definately cut down the life expectancy of the card with that temp, and unless you have a VERY good rditor/heat diffusion system, then your PC will start to fuck up REALLY fast REALLY soon if the system temp doesn't come down. This is why I comment on airflow. If you have no fans, then where do you expect the radiator to get rid of the heat to ? It'll just pile up in your system and your CPU and GPU will heat up and melt down, or your Mobo/HDD/DVD will fry because the excess heat is released through the pipes and radiator somewhere inside your case.

In essence: It doens't MATTER if your GPU can handle the temp. The rest of your components CAN'T, so get rid of the heat !

No it wouldn't... because the Water Would Circulate and cool down the card..

Much like how a radiator cools down a car, even when you can fry eggs on the engine.
