Oh ok. If it is only a processor and GPU I have to cool and there's room I suppose that I could use the next size up tubing and split it in two inside the xbox then using the tubing I currently have so each gets it's own cool liquid. Wish I had the room for that in the 360.
Wonder if the next Xbox will be larger or smaller than the current xbox?
Thinking about it is had I not gotten the case I have I could have bought that computer style case which was made for the 360 and then mounted everything inside out of view or I could have simply cut a hole in the top and used a drop in Koolance system.
I like how the computer power supply could be adapted to work with the 360 as everything turns on and off with the power button on the 360 and things like the fan controller board, pump and flowmeter converter can just be plugged in. I do have a blacklight mounted to the ceiling above the xbox so the tubing will glow at night.
Cooling loop is finished and working great.
EDIT: I decided to try a very unscientific method to determine which fan mounting option was best.
I used a spare 120 mm fan with its power wires connected to a DC voltmeter with the fan on top of the running fan. Temps shown are with room temperature more than likely about 80F and fans at full voltage.
Here's my results.
Fan on top
Fan on top and bottom
Coolant temp 95F
Fans on top
Coolant temp 93F
The airflow seems to have increased a bit with the fans on top.
I do notice there is a very tiny gap between the fans and radiator. Will that tiny gap allow air to come through or will it be ok and if air is getting through how should I close the gap?
