Extra cooling GeForce 8800GTS

[shunail]

Hi,
I've 8800GTS SLi and both clinged with 8800GTS Accetel EK Waterblocks running with FluidXP+ Ext under Reserator2. Eventhough temperature idles at 60*C ~ 64*C. Is there any thermal pad or any other thing that I should on top of video card backside to help reduce temperature a little more?? I'm not even overclocking them!! Any idea???

What's your ambient room temp? What case do you have and what air cooling do you have for the case? The only two things I can think of is a lack of airflow through the case, which is still needed even though you're water-cooling, or a lack of sufficient radiator/water reservoir size.

My 8800GTS, loaded using RTHDRIBL, set to x16 multisampling and 1600x1200, is only 71C. That's on air. It idles at 51C.

Please make a signature with your system specs in it as required by our forum rules.

Wow, you are idleing in the 60º C range with watercooling? Do you have your processor in that loop with the resorator too?

yes!!

I'll ask again, what is your room temperature?

I'm seriously thinking that perhaps you have the waterblock installed incorrectly. That Reserator should show a temperature of around 25C +/- 5C at full load from the air cooling solution. Are both cards running the same temps? Barring a bad waterblock install, try aiming a standard house fan at your rig with the side cover off. Then, try aiming the fan at your reserator2. If the temps drop with the first setup, then improve your case airflow. If it improves significantly while pointed at the Reserator2, you may have too much for that W/C system to handle. Other things to consider, did you lengthen the input/outlet waterlines at all? If your room temp is 85F+, then the Reserator is going to have a hard time keeping the temps down with 2x8800GTS's IMHO.

I think Quakindude is on the right track. Follow all of his instructions. Although, a E6600 and two 8800GTS would get pretty hot, 60 degrees is way too hot.

Do you temperatures instantly hit 60*C idle, or do they slowly climb to 60*C after a long cool off period? At least 100 watts for each card, and 90-100 Watts for the CPU. 300 Watts of heat can even be tough to active cooled radiators, you may just be going over the reserator's physical cooling ability.

You might be on to something.

Sounds to me like someone needs a triple 120mm rad with some big delta fans on it.

Well, room temperature is mostly 72*F ~ 76*F. These EK waterblock are installed correctly and been clinged with card with thermal pads in between provided by manufacturer. I'm thinking either I switch to Koolance 8800GTS waterblocks or Swiftech Apogee for these cards and add a radiator w/ 120mm fan (mostl likely swiftech MCR120-QP) after video cards.

Also placed a fan facing Reserator 2... lets see

Definitely actively cool your radiator. I'd suggest getting a REAL good one, or modding some fans onto your current setup.
