With a bit of time and patience you too can get these sorts of results. While water cooling isn't for everyone, whether due to the lack of funds or desire, the temperatures I received for my time, effort and struggle are more than worth it over any excuse I can come up with. I spent more time removing one of the original heatsinks than it took me to prep and install both blocks twice, as I had to verify contact and spread of the TIM on both. In my situation, as my PC sits on a table about three foot from my ear, this was not only a win in the temperature column, but a huge plus in the fact that my ears no longer bleed during intensive gaming sessions.
I mentioned that the surface of the block showed a lot of the milling marks, and even though it isn't lapped to perfection as a few of us tend to do to blocks after we get them, the DD-GTX 470 has no issues with contact of heat transfer. The testing and results section showed us that. With an air cooler my cards weren't able to overclock that much with the stock fan profile, and even when adding my own profile, I still broke 100 degrees Celsius. Adding a pair of the DD-GTX 470 blocks, and using it on just an average loop brings well over a 40 degree drop in temperatures at load, and just more than 20 degrees at idle. What is there not to like about that? When I wasn't trying to break forty thousand in Vantage with these two cards, I turned the clocks and voltage back to a more tame level, and I was really hard pressed to break 50 degrees on a day to day level.
I have seen samples of the 470 that can clock a little better than mine, and I have seen cooler versions, but nothing even close to what I got with my DD-GTX 470 blocks. From what I gathered, my temperature results are still some 20 degrees better than the best 470 results, overclocked or not. If you already have a loop and are planning on getting a GTX 470, I highly advise the DD-GTX470 block as your choice of an easy to install and a seriously "kickass" product. There is no easy way for me to try to pass this onto an avid air cooling guy, as they will say, bang for the buck, it isn't worth it. To me it will cost me at least $50-75 to get an average cooler that may offer only a 10-15 degree drop in loaded temperatures. Whereas not only did I see an incredible difference in temperatures and noise, I also saw the benefits in increased overclocking. Under water I was able to run Vantage at 825/1070/1650. Not a huge increase, but an increase all the same, especially on the memories ability to overclock more.
Now, with water cooling there is more cost to incorporate than just the blocks, but my plan here was to show that even with a three year old pump, a used radiator, and a few parts I picked up from PerformancePC's, I was only into the loop for about $175. As I say, for me I plan to cool even more so I can offset some of that to the CPU and chipset I am about to cool, but for what I got as results, it's still a drop in the hat to me, and well worth every penny. The DD-GTX 470 full cover blocks are currently demanding $119.95 directly from Danger Den, per block, bringing my budget total to just over $400 starting with nothing. Considering I had to spend almost double that to get the cards anyways, it is still a good investment in not only my "epeen" in bench marks, but adds tremendous longevity to my investment as they are running faster on water than air, and at about half of the highest temperature I got air cooling them.
