What I am about to show you is something that is not for the faint of heart and I will not be liable with what you do to you card. The process at first for me was a bit daunting considering what would happen IF.... After doing some practice, I realized how easy it is and I proceeded with the installation. As I am writing this, my mind is blown away by the amount of money I have just saved going this route because I could not afford to spend another $500 using a watercooling setup for my $500.00 gaming card. Attaching a cpu cooler is quite possible with the bracket which was provided by Dwood over at overclock.net. To think that a $9 bracket would hold a Kuhler 620 to a gpu die did not cross my mind but hey, it happened.
Here is a 2 pictures of the bracket with my Noctua 92mm fan attached.
Installation is pretty straight forward and the pictures can speak for themselves.
Here is my baby But%^naked.
Removing the shroud and the heatsink and fan is super easy. Removing the shroud from the 400 Series was a pain in the butt and was quite easy to break the pins.
Here are pictures of the bracket holding the PCB and Kuhler in place along with my system once installed the case.
There were to things that I had with me to ensure that everything was operating at normal temperatures. Pictures below.
Here is the fun part and where my hard work became evident an hope you enjoy. Here is a picture of my idle temps after 30 hour on desktop.
And here is a picture of Heaven after 30 hour under 99% load in continuous looping.
My system during these runs was dead silent and running quite cool. The purpose for the Temp gun was to extract readings on the back of the PCB board and the heatsinks. Under load, the highest I saw was 140f on the back of the PCB where vrm sits was 135-140f. In the front I had to squeeze the lazer between the fan and the heatsink where the sinks cover the VRM was reading 120f because of the 92mm fan. The left side of the PCB where the left vram chips sit were 120f and behind it were 125f. Finally, the back of the PCB where the GPu die sits was only 7 or 8 celsius than the gpu under load.
Room temp 23
Dba could not hear.
One added plus was that during the looping my GTX 680 did not downclock. Hopefully this card will live much longer because of the cooling.
I am not much into overclocking, but I overclocked the card to 1259 and temps rose only 2c during the heaven loop with no crashing.
What do you guys think? I tested other games Skyrim 37c to 42 under load. Battlefield 3 46c load, Mass Effect 3 37c load.
ps. the bracket is compatible with h50, h70, kuhler 620, kuhler 920. He also make brackets that will fit other corsairs; just pm him with what you would like. http://www.overclock.net/...e-badges#post_16861501 http://www.overclock.net/...tures-and-temps-inside
