The 690II also has a remarkable amount of space for internal radiators, with potentially enough space to water cool a CPU and a pair of GPUs.
You're talking about with the stock fans and setup, right?
In stock form the XL only comes with a SINGLE 800 RPM, 38 CFM, or so 140mm which is pretty anemic... Quiet sure, but not exactly made for cooling high end components.
I have a feeling that the Define XL would be a pretty capable air cooling case if you put a couple of low RPM Yate Loon 140mm up front, and a 120mm low RPM Yate in the optional 5.25" bay fan slot. You'd be looking at 103 CFM increase over the single stock 140mm. I'd put that up against a Phantom any day.
I put two Yate Loon 120mm low RPM fans in the front of my v2000 (only comes with a lower compartment fan) and it dropped my CPU load temps from the mid 60's down into the mid 50's and my GPU temps from loads in the low 70's down into the mid 60's. They're cheap as all get out and quiet too.
Regardless of the 800d or Fractal, the OP should be happy with the Phantom.Edited by whiteslashasian - 5/24/11 at 11:27am
