I just read in Huang's "Hacking the Xbox" a warning that the fanless heatsinks are prone to overheating if operated without the disk drives installed over the motherboard. I was just about to replace my 1.0 GPU heatsink (with the fan) with the later, fanless, one with the idea that I'd reduce the noise. But now I'm having second thoughts, as I will not be replacing the disk drives over the motherboard.

Can anyone offer me some sage advice on whether or not i should keep the 1.0 heatsink?

I may end up shaving ~1" off the top for a slim build. Would this eliminate the potential risk of overheating?

The drive mounting trays form a ducting to force the air past the CPU/GPU heatsinks.

If you  are planning  slim then keep the version 1.0 GPU heatsink and replace the fan on it, I would also recommend a fan on top of the CPU heatsink because you will need a smaller fan on the rear of the case so the extra fans will help.

Thanks, SS_Dave!

Could connecting an extra fan potentially overload the power supply?

If not, then are there fans that would fit on the existing CPU heatsink, or should I consider replacing the heatsinks entirely?

That not a problem the fans are running of the 12 volt supply and it has plenty of reserve supply. Even the fan speed controller on the board is able of running 2 or 3 fans

There is no one fan I would suggest it going to work better it' something you need to test for yourself and depending on what's available in your location.

You could change the heatsink but the problem is holding the heatsink on the CPU.

How about recreating the ducting with a sheet of aluminum secured in the approximate location that the drives would otherwise rest? Is this a viable alternative to my problem?

I have tried that and it kind of helped a little bit,

Don't forget when you remove 1 inch of height the stock fan will not fit so you need a smaller fan that will not move as much air as before.

A lot of people the make slims use fans/heatsinks from graphics cards in place of the stock heatsinks.

Well that gives me something to mull over.

Thanks a ton for your help.

      Hi,
      I have managed to load games directly from ISO files without a problem, but today I played Futurama and it doesn't save. I then extracted the ISO and I can save the game and options without problem. I still like to make this work from running it directly from the ISO. Is there anybody who has encounters this and an idea how to fix this?
      I have used the "XISO to HDD Installer" to create the default.xbe but I wonder if this is a certificate issue of some kind.

      My brother gave me his old xbox v1.4 halo edition (w/ the green case) that he tsop flashed many years ago....he didn't have a hard drive in it but I have an unmodded xbox here w/ a hard drive.  thought I'd put the hdd from the unmodded stock xbox in the the tsop flashed box and see if it'd boot....it comes up w/ error 16..so I burned a copy of hexen 2020 to see if I could get that to load.....it's stuck on the splash screen (the xbox logo; x on top of the word xbox) w/ the text linux under it and the purple evo x logo in the top left corner; i've attached a picture of it)....is this 'cause the hard drive is locked?  is there a way around this, i'd like to be able to use the xbox.
      Thank you.

      I picked up a dead xbox, $20, I want to see if it can be fixed. (I believe its 1.6 board, xcalibur chip and MFD 2005 )
      Pressing the power button spins the rear fan but stops spinning when I stop pressing the button. No other signs of life.
      No signs of being opened before. The power board powers up my other good v1.6 xbox fine, so a bad power board can be ruled out. Plugging my other good power board into the dead xbox has the same fan spin only result. I transferred the DVD to my good xbox and that works ok.
      I notice 4 of 5 caps bellow the CPU are blown - I've got 5 new 3300uf 10v caps coming in the post to replace them ($6 ebay), I looked on Digikey but $24 just for postage 😞 The closest Jaycar stock is 4700uf 16v.

      I noticed the 1.0f 2.5v gold cap in there too, do the 1.6v suffer the same leaky problems as earlier xbox version timer caps? needs changing?

      I don't expect to diagnose anything further until the 5 3300uf caps are replaced, but wondering if in the mean time there is anything else to check? or perform after caps replaced.
