Mr-Protocol Posted January 11, 2012 Share Posted January 11, 2012 (edited) I did a simple fan mod to my pineapple just to help with cooling.Parts Used:Step drill bitTapered drill bitSpare chunk of PVC pipeblock of woodstrong adhesive5V low profile fan (Took it off an old video card and detached from heatsink)Dremel tool.Steps:The OM1P had some reinforcing plastic rails I filed down with a dremel to make it a rough flat surface for mounting the fan.What I did was setup the block of wood as a base so I wouldn't drill into my counter top. Set the PVC pipe on top and set the lid of the OM1P over the PVC pipe.I first used the step drill to get it started in the best location away from internal components so the fan is out of the way. After that bit got as large as it could go, I used a larger tapered drill bit to slowly get the whole to the correct size.After that I carefully dismantled the plastic 2 pin plug that was on the fan wires which left me with the fan, wires, and little bits of crimped on metal pin holders.I placed some adhesive in a generous amount to the corners of where the fan would be on the lid so it would seep through the screw holes to hold strong. Placed it in the center of the hole and let dry overnight.Plugged in the wires for the fan into the VCC and GND of the serial pins and reassembled.

Mr-Protocol Posted January 14, 2012 Author Share Posted January 14, 2012 And now the AP51 Mod just like the OM1P. Quote Link to comment Share on other sites More sharing options...
Thetra Posted January 14, 2012 Share Posted January 14, 2012 That`s just Pure sexyness Mr Protocol. Love the hack! will try to replicate/modify this my self Quote Link to comment Share on other sites More sharing options...
Sebkinne Posted January 14, 2012 Share Posted January 14, 2012 I love this mod. After hearing the temperatures, I am impressed. The only thing I would add is some sort of grid on the outside, if you put it into a bag or similar for stealth it may get caught on something if you don't take care. I know this won't happen to Mr. Protocol but for others.. Best, Sebkinne Quote Link to comment Share on other sites More sharing options...
Munch Posted January 14, 2012 Share Posted January 14, 2012 sweet idea , will def do this little mod to mine when it arrives , cheers :) btw big thumbs up to hak5 , been watching darren and mubix vids since begining of dec , yeah where have i been i know lol , anyways im here now :) Quote Link to comment Share on other sites More sharing options...

I know this won't happen to Mr. Protocol but for others.. Best, Sebkinne Yeah, the best thing would to be a screen that is used on house windows or something. Also finding the low profile type fan may be hard to find. You might have to trim some of the plastic to get it to fit properly. The reason for the offset hole is because of some components on the inside. Also the fans I used were a perfect match because it actually gave some room to let air flow through the fan; unlike this other 5V fan I had. And yes, the temp differences were amazing. From ~130F/54.4C to ~90F/32.2C on the OM1P with 2.0.1 firmware after 3 hours. The best part about this mod is that it was pretty simple if you have the tools (mostly the drill bits) and take apart the plastic connector to have the crimp on pins still attached. And using the VCC and GND on the board was a HUGE "DUH!" moment when I was trying to find an external way to power this. Finally it clicked that it should have ~5V on that pin I had totally forgot about. The OM1P was the first one I did. Took about an hour (not counting adhesive drying time). The AP51 was modded up in about 10 minutes (minus adhesive drying time) because I knew when the taper bit hit the block of wood going through the PVC pipe, it was the correct size. Which that part worked out by chance. Quote Link to comment Share on other sites More sharing options...

abs0lut3z33r0 Posted January 17, 2012 Share Posted January 17, 2012 (edited) how much is the voltage between Vcc and GND pin? when i checked it showed only 3.3v! on a alfa ap51 Edited January 17, 2012 by abs0lut3z33r0 Quote Link to comment Share on other sites More sharing options...
Mr-Protocol Posted January 18, 2012 Author Share Posted January 18, 2012 how much is the voltage between Vcc and GND pin? when i checked it showed only 3.3v! on a alfa ap51 Is that on battery of A/C Adapter? I got about 4V if I remember correctly, which was enough for the fan. It should be close to 5V if I remember correctly. Quote Link to comment Share on other sites More sharing options...
abs0lut3z33r0 Posted January 18, 2012 Share Posted January 18, 2012 On 12V AC , 3.26 was the exact voltage between pin1 and 4 Quote Link to comment Share on other sites More sharing options...
Mr-Protocol Posted January 18, 2012 Author Share Posted January 18, 2012 I'm done taking mine apart so I won't check mine again. But it works. Not sure if you can tell by the picture but it's a really thin fan. (If you check the photo album, first picture) It used to be screwed onto a heatsink which was then attached to a chip on an old ATI video card. It had 2 of those type of fan setups which worked out great for me :) Quote Link to comment Share on other sites More sharing options...
Marlboro Filter Posted January 19, 2012 Share Posted January 19, 2012 Mr-Protocol : i'm thinking to put a fan on my MK3, but i don't know which pin stick to power up the fan. if you can give some mark at my picture i'm really appreciate it very much :) :) :) Thanks Quote Link to comment Share on other sites More sharing options...
Mr-Protocol Posted January 19, 2012 Author Share Posted January 19, 2012 You CANNOT run that fan off the pins I did because it is a 12V fan. You can only run a 5V fan off those pins. You need to basically destroy that white connector. If you get a small screwdriver, you can pry back the white plastic tabs on the top of the connector to let the pins free. Or just break them off completely and the crimped on connector should stay in tact and slide right out with the wire with a gentle pull. I would see first if your fan has enough clearance for actual air flow. You will have to find the 12V regulated voltage on the board elsewhere near the power plug and tap off of that. Hopefully you have a step drill bit and a tapered drill bit to make a perfect hole. If you find a 5V fan and remove the wires carefully as stated, and it fits with room for air circulation, here is the pinouts: +---+ |GND| +---+ |TXD| +---+ |RXD| +---+ |VCC| +---+ +-----+ +-----+ +---+ |Power| | LAN | |Ant| VCC would be your red wire and GND your black wire.

Marlboro Filter Posted January 19, 2012 Share Posted January 19, 2012 Mr-Protocol : Thank you very much for the tutorial. Ok, i'll post it here my fan mod after i figure it how to power up 12v fan (battery will be my first idea :) :) :) :) ) Thanks again Quote Link to comment Share on other sites More sharing options...
Mr-Protocol Posted January 19, 2012 Author Share Posted January 19, 2012 Your first check should be to see if you have clearance for air to move. You need about half the space from the RF shield to the top of the case open for air flow. If that fan fits, you probably should just solder on to the points the DC plug uses for power. Simple enough to power a fan of 12V off of that. That way you dont need a battery pack for it; or another battery pack if you plan on using the router itself off of battery.

Marlboro Filter Posted January 20, 2012 Share Posted January 20, 2012 i cant find any 5V VGA fan at my local area :( :( :( :( so i'm thinking will use 12V with extra battery pack Quote Link to comment Share on other sites More sharing options...
Mr-Protocol Posted January 20, 2012 Author Share Posted January 20, 2012 This looks REALLY close to what mine looked like attached to the heatsink. http://www.tedss.com/260-0015-001/ Quote Link to comment Share on other sites More sharing options...
Marlboro Filter Posted January 23, 2012 Share Posted January 23, 2012 Here's my MK3 mods. it's not look so neat :( :( but it's work. Compare it with MR.Protocol,MR-protocol mod look so neat. i'm trying to figure it how to make this battery can fit inside the case. Quote Link to comment Share on other sites More sharing options...
