    This project took me a year or so, where it could be done for couple of weeks, or a month at most :eek: It's running from quite some time now (you can see when the pictures were taken) and I'm pretty happy with it.

    Additional CPU, Wi-Fi and RAM heatsinks

    [​IMG] [​IMG]

    I've cut out all of the aluminum fins and made a copper ones (25) with custom profile, so it would be able to take a heatpipe. The heatpipe is from a friend's Gigabyte 8600GT Silent, I gave it a custom profile so it can fit under the bonnet :) All the fins are glued with Arctic Silver Thermal Adhesive, two at a time since I have to hold them down for about 5 minutes. Pretty tricky and time consuming job. It's not state of the art, but I don't care :p

    I made holes on the thermal pad so it can fit perfectly on top of the GPU

    [​IMG] [​IMG]

    I've put some AKASA thermal tape on the heatpipe and it's ready

    Final setup

    Smile :)

    And the most important part - it does what it's meant to do :D
    -10ºC under FurMark :eek:

    [​IMG]

    There is still room for improvement, like adding a thin copper plate between the heatpipe and thermal pad, or cutting the entire GPU part and using a heatsink from another laptop... and so on, but I'll settle down for a while :)

    Credits should go to all the cooling overhaul topics around the forum (too many to list) :)

    Update 06 April 2012:

    Stage II + Turbo Upgrade :p

    I'll have to add some pics later, but the most important are here :)

    [​IMG] [​IMG]

    Added copper shim to the 2nd GPU heatsink, and also there's now 1,5mm thick 7W/mk Phobya XT thermal pad. Don't have exact measurements, since the room temp is different, but I guess it helps for 2~5ºC less.

    And now the most important cooling upgrade - the fan itself:

    Everything packed well, so no aluminum/plastic dust would get inside.

    [​IMG] [​IMG] [​IMG] [​IMG] [​IMG]

    Re-seating the third screw.

    [​IMG] [​IMG] [​IMG] [​IMG] [​IMG]

    After every good party, there's a pile of garbage :D

    [​IMG]

    Here are some before/after pics. I got both fans thanks to King of Interns, from his parted W860CU.

    [​IMG] [​IMG] [​IMG] [​IMG] [​IMG] [​IMG]

    There were some sacrifices in the process

    [​IMG] [​IMG]

    Thankfully, there's no audible difference before and after the intervention. Well to be completely honest, the left speaker probably lost a little deepness :eek: But just a little.

    Final setup

    [​IMG] [​IMG]

    It was quite of a grinding, indeed. Arctic Silver Thermal Adhesive used here as well.

    [​IMG] [​IMG] [​IMG] [​IMG]

    And finally, some back plate modifications. Stock mesh replaced with DEMCiflex mesh only.

    [​IMG] [​IMG] [​IMG] [​IMG]

    Update: 09/02/2014

    Stage III - SuperCooling

    - What do you mean SuperCooling?
    - Twin fans; triple heat-pipes and vapor chamber for the GPU; lots of copper aaaand a meter long pipe for water coooling :D

    That's it for now, thanks for reading :)

    Very good mod triturbo! Do I read 10C load temp for your 4670 or 10C drop in temp from previous temps??? Can't believe it lol

    Btw I am looking to loosen memory timings on the card or perhaps even perform a volt mod on the card during the coming months... will keep you posted :)

    Also nice one on the 8GB ram upgrade! I have a Intel X3380 in post on way to me as we speak as my next upgrade :D

    In your screenshot of the ram its only showing 4GB accessable in the windows task bar.

    Also Heatsinks on the wifi module?

    Otherwise nice.

    I'm a bit

    Did you bend the heatpipe? How? They're pretty fragile...

    I think he bought a second heatpipe or perhaps had two separate heatpipes welded together. Probably the first rather than the latter though.

    LOL I wish it was the former, but sadly it's the latter :eek: Here's a screen

    [​IMG]

    What kind of soft you'll use for that task (loosen GPU mem timings)?

    A Xeon, nice :D I've just received a SLAQJ, but it wont post, it has a scratch on it, so I guess I'll have to return it and buy another one :(

    I don't know what you mean :p

    [​IMG]

    Why not?! After extensive use when I open the laptop they are pretty warm :)

    I thought as you, but I had to try it, otherwise it wont fit, and it's OK.

    As you said I bought a heatpipe and a second heatsink so I was able to work over one of them as much as I want (a year in that case :D ).

    Ouch still 84C at 1.1V stock clocks?

    I don't want to make you feel bad but in crysis 2 I tried fans at full speed for a while at 750/985.5mhz for a laugh and after an hour temps on GPUz reported max 53C :eek: !!!

    Yeah, 5920G's cooling is poor but I love the damn thing :D

    Indeed. I love mine too :) So what is your next upgrade going to be? Once I have installed the X3380 (once it arrives....) intend to upgrade wireless card perhaps and also go back to SSD.

    Are you planning to put an extreme chip in your acer?
