AMAZING TEMPS! Danger Den GTX 580 Water Block

[mikellini]

OK, admittedly this is my first time WC'ing a video card; I've done a few CPUs and chipsets, but never GPU. However, I think this is just insane:

Temps before (Stock HSF): Idle 44 Load 88

Temps after (Coolant 30 degrees C) Idle 30 Load 48

This is nuts! The GPU is the same temp as the coolant! Unless there's something fishy going on here... and the load temps dropped by 40 degrees!!! Can't wait to up the volts and see where this takes me...

EDIT: I could see how some might think this looks fishy; actually it does. But it's not. The coolant remains at 30C at all times, I'm running a Boreas so it just ramps up and down to maintain coolant temp... actually it only ramps up to 80% under full load, I could probably drop the coolant temp a couple degrees as well, but it's cooling an overclocked i7 920 too so I don't wanna push it

48C sounds about right. My 5870 is around 45-50C at load. Gotta love WC temps :)

nice. so 48c under furmark extreme? :)

For a load I'm looping the 4th graphics test on 3dmark 11

k., load up furmark and chose the extreme burn in. that will probably max out anything else. oh yeah, and you can disable the limiter too if you wish

Welcome to the club. Once you've WC'd a video card, you'll never run air again. Unless you are waiting for your block to show up. My heavily OC'd 470 idles at 35, and Furmark load is 49-50.

[mikellini]

Don't think I need to do that, I've upped voltage to 1.138 and I'm testing clocks around 930, and the coolant temp can only be held at 33, running full blast. Time for a rad I think :)

hehe... Watercooling is the way to go. Like SugarJ says, you'll never want anything air cooled again. I have 2x OC'd 5870s in a loop with an XSPC RX240 and I idle at 22 and 26 (ambient of 18-19). Can't remember my load temps off the top of my head...

To see the load you should do furmark as that is the ultimate stress test.

I guess what blows me away the most is the idle temp. This block must be damn efficient to get the GPU to the same temp as the coolant. My CPU block is pretty efficient and core temps are 8 degrees above the coolant temp. Of course, that is with no power saving features enabled at idle, unlike the 580 which downclocks to pretty much nothing at idle
