Since I upgraded it to a Palit Jetstream GTX 770 I had to pull it back to 220 MHz and even so my motherboard (Sabertooth 990FX) sensors were showing temperatures over 50ºC at several places.
The GTX 770 was hiting 81ºC when playing Grid 2. I didn't run any stress test with this setup. I really didn't want to see the result
I opted for the zip ties solution since getting any bracket or adapter would be difficult, living in Brazil. Post service and our Customs are something to avoid if you can.
I got the Kraken X40 because of the lengthy tubes (40 cm) since I mounted the radiator on top of my case.
I can´t say how happy I am with the results. Running a lot of stress tests (OCCT, Furmark, Unigine Heaven and Valley) the card reached 54ºC at ambient temperature of almost 30ºC. In games it barely reached 50ºC.
To start the work I had to do a little case modding as my case isn't intended for water cooling. I cut out the top openings and made some way for the coolers tubes. Something like this:
To help keeping the VRM's cool I decided to keep the original heatplate and as I didn't want to use a shim, I had to adapt it so that the X40's block touches the GPU core:
Enough space for the X40 block:
And now the zip ties:
Installing the Graphic card and a 92mm fan to cool the heatplate:
Almost the final assembly:
The "paranoid factor", as this card is factory overclocked and doesn't have VRM temperature sensors I decided to install another fan (from a an old CPU heatsink) on the back of the PCB. More zip ties here (the white ones are just a kind of "suspension" to keep the fan away from the board and get better ventilation, the black one holds the fan in place):
That blue led fan is to cool the motherboard's VRM's down
