Should pick up a Heatkiller for that sexy chip.
Have you considered watercooling your board too?

I haven't tried it, also correct me if I'm wrong, but I think you can't change the 2 140mms fans for 120mms

I do not plan to watercool this board as i believe i would need a second radiator for that. i edited my post with a full parts list for both water and cabinet cooling. and the NF-P14 are 140mm fans.

Looks good. However, I wouldn't bother replacing the 140mm fans. The great thing about Noctua fans is that they cool well quietly, but you're putting them in places that don't require high static pressure, so the only advantage is that they might move air more quietly. If that's worth $50-75, be my guest, but I don't think it's worth it personally.

Also, as for your custom fan bracket, the radiator fans are gonna move a ton of air from those areas anyway, so it's not really necessary. I mean no offense, but for better or for worse, this design seems like a major exercise in overkill.

I have tried this Cabinet with aircooling only and i am not quite happy with the airflow. I believe the noctuas can move more air and still be very quiet.

There is a way to mod the Obsidian 800D to house a 240 (120.2) radiator at the bottom. If you where to do that you could add another loop for your motherboard, or just expand your loop. The mod can be found here: 800D Bottom Radiator Mod - Visual Guide - The Corsair Support Forums

I personally would use a ThermoChill PA120.3 w/ 3 Scythe Gentel Typhoons And would go for the HeatKiller CPU block as well. OR wait for the new EK Supreme HF (High Flow coming out)!!!

However, the TFC ones are good too.

That is a very nice guide for the extra radiator but i do not want to do such a drastic change to the cabinet. I am hoping i will not have to watercool the board with the changed out and added fans i have sketched up.

Noctuas are junk for that.. Pick up some Sycthe Slipstreams for cheaper and better.
