So I Jtagged my Falcon a while back and noticed the daft temps my machine was ruinning at, now I'm no expert (As your about to see) on 360 temperatures and cooling, though I did some overclocking and PC cooling mods many moons ago but I'm pretty sure that 60-70 degrees C is not desireable. So in an effort to prolong the life of the Jtag unit I decided to 'fit' some extra fans...
It's a 'work' in progress, as in I'll probably make it slightly more permanent in the future. It cost a grand total of £6 for a USB powered 3 fan laptop cooler but the main thing is it knocked about 20 degrees off each of the main components which was my main aim.
I might cut the lid in the future and maybe get an Xdrive unit so I can keep the drive external and tidy as I don't really use it with tha hard drive etc.
That was something I thought somebody on here might be able to answer. I tried just connecting the PCB from the DVD unit but you get a constant flashing power light on the power button, I'm asuming this is due to the unit detecting a missing component, probably the laser unit etc. Anyway to trick the unit without flashing the nand etc? So I can leave the bulk of the drive out to create space for the fan when I put the lid back on?
It's a crappy looking but effective mod, definitely nothing that hasn't been done before. I just thought I'd put it up as it don't require any work other than opening the 360 case, might help with those having problems with freezing etc. Oh and the neons were not intentional they just came in the fans. one plus point is the fans start cooling before you even power the 360, due to them being USB powered and they also continue to cool the unit after you power the 360 down, but they'll only go off once you switch off the mains.
So anyway there it is, mainly aimed at those who may not have the means, money etc for anything more drastic and from what I can see it did the job
get long sata lead and a longer power lead for the dvdrom drive,that way you can have the lid on and run the dvdrom from the outside,also giving you the dvdrom to make a caddy for adds a bit to the project.obviously you will have to do a small bit of tactical cutting to run the sata and power lead to the outside of the 360 unit but done right will look nice,you could also think of placing a rubber grommet in the cuts you have to make and that will tidy the holes and stop the edge of the plastic from cutting the wires.
Been some progress since last time Saleem, it has definitely gone in a more classy direction.
Got hold of some quiet 5v fans and mounted an 80mm directly on the GPU main heatsink and a 60mm (External) over the pipe and CPU heatsink (Falcon). Cut holes in my Elite case for both, fitted grills and found that I could get the DVD to function with an old Hitachi DVD PCB with only the small motor that works the opening mechanics of the tray. USB powered both fans using the rear port, simply ran the wire out the back of the case back to the port which I've never used. Will use the grommets like you suggested, some in the broken Gamecube I've been pecking away at for parts.
Also trimmed out the rear grills on the metal and plastic case in front of the stock fans to quiet them down and increase air flow slightly. Gonna get a Nidec fan from an older unit to replace the noisy stock fan which makes way more noise than the new fans put together, actually more noise than any fan I've had. The increase in nose from the extra fans is barely noticeable.
Good call on drive, been looking at something similar. I'm not sure if I'm gonna re-connect it yet as I have another 360 to install games on to my HDD when required and ethernet to the PC for Jtag items. Also I've found somewhere I can get 20" power and sata cables, ribbon type if required. Although I'm thinking next time I update my dash I might create a nand with the no DVD drive hack and remove the board completely.
The end result was a continued drop of at least 20 degrees on the GPU, CPU and ram, so I'm very happy with the results. Only other thing I might add is a grill over the DVD drive to tidy it up a bit.

Nand flashed with no DVD drive option and dash updated to 13599 using the excellent 360 Exploit app. DVD drive now totally removed. Pins 4 and 6 on the DVD power connector bridged with an old IDE jumper to stop the flashing power light. Used the grill I cut from the rear stock fans inside the DVD drive opening to tidy things up.
Last things to do are replace HDD with a 750gb and fit the quiter Nidec stock fan thats on the way and it's job done. It's basic but I'm very happy with it, total cost was probably less than £25 (Not including HDD)
