Heat Killer GTX 295

That's a nice block. I just went water on my gtx295 using the Koolance block. I haven't seen temps much over 50 under load. It's in it's on loop with a dual Feser rad.
 
The HK block is really nice and I've been trying to decide between the HK block and the Koolance block. The HK block looks a lot nicer and is supposed to be much lighter. I'm considering the Koolance block because it has stand-offs to prevent the card from warping due to over tightening the screws.
 
The Koolance block is actually somehwat lighter. The HeatKiller weighs 1200g whereas the Koolance block is 1000g. The lightest GTX295 block available is actually the Aquacomputer block which weighs 700g. It was actually my first choice but it wouldn't have worked out for my planned build because of the inlet and outlets being on the side of the block instead of top and bottom like the other blocks.
 
In the end, the amount of copper in the block isn't what's important. More copper in a waterblock isn't necessarily better than having less. The point of watercooling is to get the water to absorb the heat, not the waterblock, the block is just a vehicle to transfer the heat to the water. If the extra weight doesn't help transfer the heat to the water, then all it does is weigh down and bend the card.
 
I went with the Koolance block for my GTX295 and I reach my cards limits before I ever go over 50c.

The copper will remove more heat from the loop and dissipitate it through the water and air...:rolleyes:

The best on the Market, atm...HEATKILLER® GPU-X² GTX295

You need to read what you just typed. The object of watercooling is NOT for the waterblock to dissipate heat into the air. It's to dissipate it into the water. Having more copper in the block isn't necessarily an advantage or a good thing if it prevents the transfer of heat into the water. Learn to use your brain you dunce instead of just posting your opinions as if they're factual.
 
I agree, more copper doesn't mean better. But what does matter is total surface area of copper coming in contact with the water is best Its all about how much of the water comes in contact with the copper and more copper in contact with components for more heat transfer. Too much copper can actually make it less efficient in a water cooling setup.

As long time water cooled pc builder , I totally agree with your statement above. This will be my first HeatKiller product so the jury is still out until I’ve had the chance to inspect the craftsmanship of the block.
With only my stock clocked i7 940 in the loop my pc temperatures stay at 1 -10 degrees above ambient and only +15 when pressed. However, since I have an internal radiator, once the gaming begins my GTX 295 dumps heat into my case raising temperatures a few degrees for all components. Recently the GTX295 hit 91c after a very long gaming session triggering my user configured alarms. The heat from the GTX295 is not properly routed to the rear by the stock fan.

My typical Loop
Rad --> CPU --> GPU--> Res-->Pump-->Rad
 
This block is heavy as hell.. I need to build a support brace for this as I move the case often and fear I may snap the card in two. The plan is install the card in the buttom PCIE slot of my P6t WS Motherboard and add a small metal/rubber bracket attatched to the bottom of the case. Allow the card to rest on the rubber lip of the bracket between the g1/4 in/out ports. I will loose access to the unused bottom PCI slot. Anyone else fabricate an additional support for GPU waterblocks?
 
I didn't, the XSPC 4870x2 block I have is heavy, but not overly so. Plus the card has a built-in backplate, so I'm not worried about it warping.
