Unboxing the waterblocks for my MSI 580GTX Lightnings! - 56k warning!

Yes that's right!

Just got two waterblocks to replace the rather excellent Twin Frozr III on my Lightnings!

It's a special edition of the Black Freezers from Bitspower, made to fit the weird shaped board of the Lightning:



Boxes are Bitspower standard.





Massive block!
It weights about 2,5 Kg










I like the looks of the backplate!
Brushed black steel



Arctic Silver Matrix? Never heard of it.
Any good?


Pictures of the assembled thing and "review" coming in about 3 weeks (no time now, must finish my phd)

UPDATE

Assembled at last!









Crappy pic but might be useful for someone wondering if the voltage meter spots will still be accessible with the block on



And that's that!

Results are freaking great!

Max load temps went from 83C (top) / 79C (bottom) to 47C (on both cards)!
47C was 21.4C over ambient temps!
Idle at 32C (7.4C over ambient temps!)

Keep in mind that temps depend on the loop itself and details can be found HERE.

Stress Test Temperatures

Detailed config.:
Cores' freq.: 832MHz
Mems' freq.: 2100MHz
(MSI Lightning standard frequencies, as you guys know redface.gif)


Core voltage: 1.001V (one of them runs at 0.983V , according to GPUZ, but the other runs at 1.001V);
Mem. voltage: 1.021V (increased by 20mV to improve memory stability at stock on GPU2 after observing slight purple flickering on 3dMark11 - change made when the cards were air-cooled).

Loop config.:

120rad exhaust fan at 1260rpm
360rad exhaust fans at 1080rpm

120mm intake fan (bottom of the case) at 1760rpm

Pump at speed level 2.5 of 5.

Ambient temperature steady at 26C.
Internal case temps during testing maxed at 30.5C (measured at the main case chamber in two points - back and front, 2 cm to the right of the 120mm rad and 5 cm under the 360mm rad).

Maximum observed temperatures:

GPU 1:

Core:_____ 48C
Memory: __ 37C
VRMs: ____ 37C


GPU 2:

Core: _____ 47C
Memory: __ 37C
VRMs: ____ 36C



Looking good!

I got it from here.

EDIT: Wait, got it, you mean if the tubing will match between them, right?

Anyways, the DCII is almost certainly slimmer than the Lightning. I had one so I can vouch for that. The fittings will therefore, not match positions between them.

Well, you can always try some adjustments using swiveling fittings like these double 45 degree extenders (they can make an almost S-like bend).

Something like that and some flexible tubing should do the trick

I am not sure about that.
Check the layout and the mounting instructions on Bitspower Taiwan's webpage and also contact them.

I would guess that it should not fit since the xtreme has double the memory chips and those also need to be cooled (obviously)
