Very nice mod for the dragon. I did mine quite some time ago. Photobucket has sense deleted my photos but I still have the case in the garage. One of the things I did different was I used 2 120mm fans but left the Louvers in place. I may have to get a system going just to put it back in service. Just to say its back in action again. lol. I have all but a mobo and proc to do it.
I think the best option for cooling would be this. so long as it will fit properly. I cannot measure the underhang of the front fans but I can see room beneath the fans, maybe not enough though. Check the cad drawing and see what you can measure out. Its an expensive solution but will be much better then a self contained unit such as an H100i or something similar... The only real advantage to the H100i would be that you would get it fans and all so you can relocate thje factory fan. Good luck, I hope you find a cooling solution that will get you what your looking for.
Thanks all for the information. I believe you are wright about getting water cooling because I can't find an air heat pipe that would fit. But I found out with this case I can only put the 240mm radiator in the front or bottom not the top above the CPU..OUCH! I guess that will have to do.
I am gonna wager that means you have the Spec-03, If so then there is a good chance you are not getting it up there. But a little insight on what case you are using would help us determine what is possible.
But if its what I think it is.
I did see a picture of a carbide spec 03 With a Cooler master Seidon 240 installed, they did claim the Corsair H100 will fit based on that. The issue here is you loose your ability to run anything but lower profile ram. I.E. no additional heatsink material above the top of the rams own board. something like that... it still may not fit. http://www.newegg.co...3-675-_-Product
You also Have to sacrifice the rear fan or run it on the outside of the case if that is possible. Please dont quote me here, I am only saying that because its something I would do, and unless its flat back there its not easily done.
