Whoa!! It's D-Tek's new GPU block

[Bojamijams]

30c max? Compared to my stock cooler that would be about 50C less! How is your stock cooler keeping your card at 40C on load????

Well, after upgrading the driver to 177.41 to follow the advice of Scott LeGrand (NVIDIA CUDA developer), the issues I had disappeared so it's the driver. With this out of the way, the video card is rock stable so it's now time to finally assemble it.

Card with stock cooling (EVGA GTX 260 Superclocked)


Disassembled :


Closeup of the GPU core :


Closeup of a memory chip :


Naked with all the chips cleaned with 99% isoprophyl alcohol :


With the UNi-Sink installed :


Stock backplate reused with the new UNi-Sink (BTW, the backplate is cast aluminium, not plastic as I initially thought so heat will dissipate correctly) :


D-Tek Fuzion GPU v2 disassembled :


Assembled (I forgot to install the mounting plate in that pic) :


Fully assembled and ready to be installed in the loop (with the BitsPower 3/8" barb in black sparkle finish, looks much better than the usual D-Tek HighFlow barbs I used due to a slighty bigger diameter) :


Now that it's put back in the loop, the GPU is hovering at about 41C running the F@H GPU2 client, which is great while it hover at about 54C with the stock cooler running the fan at 70%. The only bad thing about that setup is that the barbs orientation is not optimal so I must try to route so it doesn't hit or rest on the side panel. I guess a couple of 90 degrees elbows can solve it but since it's working as is, I'll leave it alone.

Even with the bad investment, I will always prefer full cover blocks because most of my systems are not going to have air passing over the video cards, so water cooling the ram makes sense. I also MUCH perfer the location of the barbs on full cover blocks, it makes it MUCH easier to SLI.

agreed

Awesome photoshoot, thanks. The quality and finish of D-Tek's block looks amazing.

Fan at 100%, very very loud though... Hence the watercooling

how does this block compare to the mcw-60. anyone tested that yet? haven't decided if i want to get a mcw-60 or a gfx2 for my 4870 yet.

On a GPU, a few degrees difference won't really matter since most GPU is volt-limited, not temp limited. I like my block but never used the MCW60 so I cannot make a comment about which one is better. However, with the fact that D-tek make unisinks, this is the deciding factor

ya im one of those people that would kill for lower temps even if it doesn't do anything :P. i was planning to get the mcw-60 or the gfx2 and then get some mc14 ramsinks and mc21 mosfet sinks and then my zm-f3 will be blowing on it from the side fan on the case. hoping that will take care of it.

The rad for the ram and mofset is hot ? Need fans ?

was gonna use the heatsinks and have my fan from the side of my case blow on it to take care of ram and mosfets.

I touched it while running under load and it's warm to the touch but not too hot. However, I have a 120mm fan blowing across the card from the front to the back.

quick picks taken from my phone with my 3870 installed. i will most likely buy the 4870 tonight.
