Well, I have a Linksys wrt54g running DDWRT over clocked a little bit using a Yagi antenna. It sits in a really hot room and I noticed its performance starting to slip due to heat. So I set out on a quest to put a fan inside the router without voiding its warranty. Yes, the router has been opened up and flashed but its still under warranty. Any who I rummaged through the pile of dead computer I have laying around and used parts from a Macbook and a old HP. The fan was +5v that I was going to run from one of the buses on the router mother board but decided not to load up the board and void warranty. So I destroyed a Iphone power brick and a data cable because it was the correct voltage and mA for what I need. This is a build thread so pics!
.
My first thought about cooling the router.....

This is the little heat sync. Linksys runs their output at 28% with no adjust-ability. I run mine at 170mW at 92%. This heat sync did not ship with linksys and was added.
This images is larger than 153600 bytes. Click to view.
So here is the idea I had in my head. This is just a mock up

As you can see in the previous pictures you can tell the little heat sync was not big enough to efficiently cool the chip. So I cut up a copper pad from a old HP I have laying around and made it so the entire face of the chip was in contact with a cooling surface.

And now its time to get power to the fan. Here is after I cut into the USB cable for my 5 volts. You can see the iphone powerbrick

And now its time to play with hot drippy metal

The entire assembly made and ready for install. Please note, this fan is a directional fan and the output is blowing over the sync

Mounted on the board.

Im going to home depot tomorrow to get a gromet and make it look better. But this will do for tonight. The only outside change.

Performance pick up is HUGE. I will get into those details later.

Im liking this......Just mod it to work. This router will never be used wired soooooo one could un solider the cat 5 ports and put a display in there.....Or hell, even in the front. Just cut a hole out and pop your display in. HMMMMMM

Edit: Re clocked at 150mW at 76%. So in other words im running it at about 3/4 power. Does anyone know the drop off rate of RG-58?

Im planning on getting some 1 watt boosters in the future. This is not set up for transmitting as its more geared for receiving. If I had a couple hundred bucks I would go all out at do a few other things to this linksys. However you have peaked my interest on your set up. Tell me more.

50ft or so depending on the dialectric before you get any any real loss. . 213 is soo much better.
your setup looks like my old setup, i ran alot of those wrg54's they get hot. i use to, as a quick measure, i would do the penny trick to it along with a larger psu and a fan sucking air on the top with a few vent holes. they ran great but eventually died. they don't like overclocking at all.
whats the db gain on the yagi?

i just got this toy a few weeks ago mounted to the roof with a tripod and rotor..
27dbi, this thing has a tighter pattern than a virgin frog.

I had the same dish back in cali! I got it with a old breeze access thing. Its a 15dbi Yagi. Im actually thinking about building a cantenna to get the directional features I want. I could give a rats ass about the TX power.......I want to bump the receiving power wayyyyyy up

mehh cantennas are nice but you wont get the performance with one as you would a properly built yagi or quad. i use to have a 12db cantenna and my old 10db homebrew yagi just out preformed it in every aspect.. and the yagi only cost me about 5 bucks to make. the cantennas now used to test backtrack when im bored

Im about install a POT to make it variable. The fan is a little loud so slowing it down might be a good idea.
