Very nie tut by all means. I would just like to comment on the quote below..
"This can be proved if you feel the temperature behind the xbox after playing a game for 15-20 minutes or so. The Right hand fan (should be GPU) is noticeably cooler than the Left hand fan (CPU) – you may think this is because the CPU heatsink runs hotter than the GPU heatsink ? This is not the case …"
The CPU side felt hotter because the CPU heatsink has alot more surface area to dissipate the heat to the rushing air. Technically the CPU heatsink does run hotter, but it just transfers heat better. GPU air feel's cooler, since most of the heat dosen't transfer to the air and stays in the box. So the tunnel over the heatsink is a great idea..It's an improvement over MS' design for that matter.
The problem I see, is spliting the air shroud to have it's individual fans. The GPU fan might actually be helping cool the CPU, and the seperate channel's might take away from that. I doubt it will kill your xbox, but I think just the tunnel over the GPU heatsink would be better.
PS- Also, the unsplit shroud might be a safety feaure. If one of the fans die, the other should be able to do the work for both.
Hi - some interesting points - thanks for taking the time to reply..
If you take a look at the temperature readings on the 'cooling with proof they work' thread, you'll see that i have since backed up the designs with some temperature monitoring. The CPU's heatsink remains relatively static throughout the analysis - but always a lower temperature with the mods (and to negate your point about two fans providing extra cooling the CPU may need). However, the GPU is another story - with massive temperature drops by doing the mods - the most noticeable is with the air flow seperator. The other point to bear in mind is only the CPU has temperature monitoring/control of both fans (yes hard to believe isn't it..) so if anything, we need to provide cooling priority to the GPU, not the CPU as it can regulate itself (by speeding up the fans if needs be).
However, your point about a fan failing and the impact this would have is totally true, I do not dispute this. If the CPU Fan died, then I hope the Xbox would shut itself down very quickly, If the GPU fan died on the other hand... Fans are pretty reliable bits of kit however and I haven't heard of any fans failures on this board - unlike the 3ROL...

Well my 360 always locks up, I put AS5 on it, Intercooler and Fanshroud thru the middle
Should I get some extra heatsinks? If I do which and where do I put them?
Hi - have a look at this thread - it will show you where to put the RAM heatsinks ...Cooling Mods Proof ...
PS - It's my personal belief that 'lock ups' ARE caused by RAM overheating with one exception - if the game locks up in the same place each time, then it's sloppy coding that's at fault, not the hardware.
PPS - Maybe tempting fate, but my Xbox has NEVER locked up or frozen in any game since getting it over a year ago, I started modding it 2 weeks after getting it lol ... ;-)
