    Ok just buy some metal mesh from staples. You know the black metal thing with the tiny little holes in them. Buy that and but 2 usb powered pc fans. Then the rest is pretty self expanatory.

    Seriously Rot.. if you don't have anything constructive to add.. why bother? Obviously we can all figure out what you just said on our own.. I mean I linked to a post that outlined precisely what you said here.

    The point being, if you'd read my post, is that there's rarely any follow up from the posters and further, I'd like to hear if there were any issues encountered during the design/build that some of us may be able to avoid.

    We're looking for information, detailed information from the folks who have built their own coolers along with follow ups to let us know how whatever design they posted about building ultimately worked.

    I wasn't bashing on you personally but trying rather to let you know that what you wrote was off the mark as far as what I'm looking for personally within the scope of my post.

    Keep in mind when wiring fans, wire them in parallel and not series. What I mean is when connecting up the fans, the positive wire goes to the positive wire and the negative wire goes to the negative wire.

    The reason I have behind his is so you don't need looking for a 24V power supply, or even a 36V power supply if you connect it in series. I would try and look for a 12V 1A power supply (possibly lower, say .8A for less demanding fans), either from an old appliance that is no longer needed or look at Radio Shack.

    I've looked at creating one last summer, but never got around to. My plan for my P-6831FX was a mesh wire case from Wal-Mart/Staples and 2x120mm fans zip-tied to the case. I never found a power supply, which was my main reason for not completing the project.

    Rubbermaid makes auto 12v powered coolers, they use about 2.5a. It would be cool to see someone impliment one or two of these, hacked from the cooler, in a powered setup.

    Sorry it took so long but here is the write up on my custom laptop stand and cooler. There is a lot of woodworking involved that I am not describing in detail here.

    Basically, I took one of those rolling laptop tables and built a new top for it with 3 120mm fans installed in it.

    This isn’t the cheapest cooler to build and is definitely not portable, but I already had the laptop table and I’m not going to lug this thing around much anyway so didn’t have any need for portability. The original stand was for my old 15” laptop and didn’t fit the P-7805U anyway, so I would have had to get a new one regardless.

    Following is a list of the hardware and links to where I purchased it, other than the actual laptop stand because I bought that a long time ago from Walgreens for $19.99 and couldn’t find it currently for sale anywhere.

    Fan Grills


    120mm Black wire fan grill

    110V AC to DC adapter w/ 12V 4pin molex connector

    Rubbermaid Mesh Wastebasket – I purchased this from Walmart for approximately $4.50

    [​IMG] Hardware picture

    The new table tops are built from 1 sheet of ¾” and 1 sheet of ½” birch plywood laminated together. I did this so that it would be thick enough to house the fans and controller. I cut openings into the top that line up with the CPU, GPU and Hard Drive vents with additional space to allow for some airflow. The openings had to be cut in a certain way to allow for the original rolling stand to mount to the table tops.

    I routed channels into the bottoms of the table tops for neatly placing the fan and power cables along with one very large opening for the fan controller. I installed threaded inserts on the bottom where the original stand mount holes were and I drilled holes where the original laptop rests were installed.

    I cut the wire mesh from the wastebasket and cut 2 pieces for the openings in the table top, leaving about 1 inch overlap. I then cut into the corners and folded the overlap down into the openings and secured them with some screws. I sanded the support beams in the middle of the openings down about 2mm below the table top surface so the mesh would not protrude above the table top.

    The fan controller is simply press fitted into the opening that I routed for it. I left the opening slightly smaller so it would stay put when pressed into it.

    I sleeved the fan cables for a cleaner look and then mounted them directly to the mesh with black fan screws. Cables were routed through the channels I put in the table top bottoms.

    It's kind of tough to judge the temperature drops because I live in Phoenix and didn't do all of my testing at the same temperature's. My best guess is somewhere around 4 to 6 degrees celcius. You can take a look at the spreadsheet I attached above and judge for yourself. Also, when I tested I had already done other cooling mods, i.e. TIM replacement and Undervolting.
