Kylning av grafikkort - Fractal Design R2

nja skulle ej tro det , skall du ha grafikkortet under 70 grader är det kraftig vattenkylning som gäller.. och det kostar ju en slant ! blocken till graffet brukar ju gå lös på 1 papp typ

Mitt 6970 blev under sommaren runt 90grader i mitt Fractal design r3 , numer är det väl en 80grader som max

What you need?
1) The custom adapter bracket. Cost is $7 shipping included
2) A spare OEM Asetek bracket (one that comes from an H50, H70, Antec 620 or Antec 920)
3) Metal Epoxy. These are cheap find any one you like at your hardware store
4) 4 x #3 or #2 screws with length of 1-1/4" with the matching nut. Also $0.98 at HomeDepot for a set of 8 screw+nut.
Optionally you can go with a #4-40 but it will require a bit more work if you choose this since at this diameter, the screw interferes with the OEM bracket outer ring.
5) A dremel to cut the feet of the original OEM bracket.
6) A sheet of rough sanding paper. Any grit will do. It is just to remove the paint from the OEM bracket. It is optional but it sticks better this way.
7) A tube of your favorite TIM if you do not want to use the one which comes with your cooler.

Total cost of the mod:
Bracket $7
Epoxy $5
Screws $1
Antec Kuhler 620 $56
Cuting disk for the Dremel $2
=$71!

What to do?

A) Take the sanding paper and rub the custom bracket face you have choosen to stick to the OEM bracket
B) Sand the top of the OEM bracket lightly until the black paint is gone from the top surface of the narrow line.

Note that A and B are really optional. We are not going to rely on the epoxy to maintain pressure on the GPU anyway.
C) Follow the instruction on your tube of epoxy and spread the epoxy on the top surface of the OEM bracket you have just sanded and stick it to the adapter bracket. Wait for at least 30min. 24hrs to be 100% sure.

D) take the dremel and use the metal cutting disk to cut off the feet of the OEM bracket.
That's it! your bracket is made.

E) Remove the the cover of you graphic card. and take apart the "Vapor chamber" heatsink. There are quite a few videos on youtube showing you how to do it if you don't already know. On the GTX 580, I just had to remove 7 screws all around the side of the cover and then remove the 4 screws from the back which had springs on them.
F) Prep the surface of the GPU with IPA and the TIM you want to use.
G) Stick the 4 screws through the 4 screw locations from the back of the card and drop the bracket on the screws. Loosely start the nuts on the screw tread.

H) Install the cooler per the regular Asetek procedure by dropping it down and twisting it into the mechanism. Tighten the screw/nut down and you are done!
