    That is very nice work. Do you think that the RF shield heats up at all ? Good luck with the power tweak.

    I don't think so. What I did was really arbitrary though... I just immediately opened the router after being on for weeks, and felt with my finger which chips were hot =D. The shield was just warm from radiant heat I suppose, so no need for the heatsink.

    I got a few off of eBay for cheap: DELTA 60mm x 10mm

    The setup works great! Everyone with a stock linksys knows that it can get hot.. and thats just the plastic case. After this mod, my wrt54gs (as a whole) is as cool as if were off.

    Thanks for the compliments!

    Initially the fan was getting the full 12v from the power adapter, so it was louder than I wanted (actually, really loud). So I added this potentiometer to adjust the fan speed. It is awesome:

    That's really cool. Are there any step by step guides on how to install a fan? I'ver looked around but can't seem to find anything.

    I don't know that there are any step by step instructions. It's pretty straight forward. The key is deciding where you're going to get your 12v power from, and then accessing it. I used the solder joints where the AC adapter plug is soldered to the board. Other than that, it's a matter of screwing the fan to the cover, drilling a hole for the potentiometer (the 'pot' is a must), and wiring it. 2 wires, red to hot, black to ground. Most pots have 3 legs. When looking at the back of the pot, the R leg is ground, the L leg is input and the middle leg is output. That is MOST pots that I've seen. You'd be well advised to test it before nailing it down.

    I've included a few photos of mine. I started with a 40mm x 10mm fan which is what you see, but I ordered a 60mm x 10mm fan and will be swapping it out soon. The sleeving on the wires isn't necessary, it's just something I like to do...keeps things neat and protected. I'll post back when I get the 60mm fan installed.

    Hmmmm I see. Well if someone could post some large pics of how everything is soldered together I'd appreciate it.
