    I wish I would have found this forum first prior to doing this mod - might have done a few things differently. I didnt even know there was an area dedicated to modding the linksys! My pdf file reads a little funny now that I know. Oh well, dont care enough to change it. I was originally going to send this to some other folks and just share it with some geek friends but maybe someone here will find it interesting.

    Anyway, Im in the early stages but so far things seem to work pretty well. One thing Ive added after documenting some of the install is a switch. I wanted the ability to turn off the fan.

    Fan specs:
    Size: 40 x 40 x 25mm
    Rated Voltage: 12V DC
    Speed: 7400 RPM
    Airflow: 9.1 CFM
    Noise: 27.0 dBA
    Input Power: 1.1 Watts
    Rated Current: 0.1 Amp
    Bearing: Ball Bearing

    Fan moves a lot of air. I have airflow set so it PULLS the air from the bottom and pushes it out the top. I noticed too that some air gets pulled from the TOP as well through the holes surrounding the fan. Didnt mind, if I put some paper on the bottom the suction created will hold the paper there!

    Update: 10degC reduction in temps as read from the OUTSIDE of the case. Thats huge.

    Since I have moved and transfered my old domain I figured it would be nice to update this thread. Either that, or Im a post whore.

    The mod I originally posted about is still working. My brother has it and I think its safe to say a moderate increase in power output has no impact on longevity so long as the cooling is in place. HOW doesnt really matter in my view unless you try for the exteme side of things.

    Anyway, since the old links are dead, you can find this mod and a newer version of the same thing here: (November 2006) in the "Computers and Internet" category. Failing that, this might work as a direct link:!60B64A716224E68A!163.entry?_c=BlogPart

    Try to keep in mind the PDF is ~1.6 mb and can be found in the blog or here:

    Others have done it better but I have no issues

    Spoke too soon... the router I left behind (v2) has been locking up on occasion - I didnt know. No idea what the problem is and dont have access to it... could be minor config issue or some pending hw failure. For all I know the fan has been off and got hot.

    In the interest of correcting myself it needed mentioning.

    Update to the update... the issue seems to have been with mega P2P and file transfers. Second unit still working fine.
