    After we do this mod, should we revert back to a previous bios so that the fan is not constantly always on? Which bios? Thank you very much.

    You should stick with A11, at least when my new mobo and materials come, that's what I'll be using.

    Be careful with A11.... I upgraded to it and had to figure out why my system went dead. For some reason, it would not accept 2 sticks of RAM. Had to remove, go to safe mode with one stick, go down to 09 and alls fine again..

    Was the freakiest thing so...tried it again...same same..

    Hey Les, was that 4GB (or 2) in total? [EDIT] Nevermind, I just saw the 4GB in your sig (hard to miss, but I managed... lol).

    ---------------------

    @Johnny13oi: My theory's that A11 shouldn't make a difference with a post Cu-Modded 1330 as the trigger value's something like 65C instead of 70C (for the GPU, in any case). At least this is what one member implied. I'm still on A09 and so I have no personal experience with A11.

    Since your GPU shouldn't hit 65C @idle (w/CuMod), there should be no difference between the various BIOS versions. Like I wrote elsewhere, my 1330 now goes much longer before triggering the fan and the trigger temp(s) seem to be one of either 48C/50C/64C for the core 0/1 and GPU, respectively.

    I'm guessing it's the 50C Core1 that triggers my fan now, but it used to be the GPU when it hit ~67C (and core1 was only @46C).

    Please feel free to post your own observations with A11 and let us know at what temp the fan starts to spin at. You can use 18kfangui to monitor all three temps (as long as you calibrate the GPU temp which is usually 10C too low). I define "idle" as no foreground activity (not even surfing).

    Thx & cheers m8 :)

    Dell is only allowing Dell branded Hynix Memories with A11 BIOS revision ;)

    My colleague tried 2x2GB generic memory sticks and it works. I wonder why it didn't work for you.

    Got my mobo and copper today. Didn't get my AS5 yet but I still had a tiny bit left. Did the mod, my idle temps are 51CPU/62GPU.

    Don't have much room for comparison though. Didn't even fire up this board on the original cooling.

    Of course, my AS5 still needs to cure.

    question, has anyone tried not using a copper sheet?
    i mean, apply as5 directly to the heatsink (attached to the copper tubing) and the GPU/CPU?

    there is about a 1.7mm gap between the heatpipe and gpu - using that much thermal paste wouldn't being efficient.

    Sounds reasonable enough. A bit more info would be cool, though:
    Ambient temp, idle temp "range" (is 62GPU max @idle, etc.)? Lastly, the results are only truly appreciated during a full load (i.e. 3DMark06 - Freeze).

    fwiw, my own current stats:

    C0 @36-48/ C1@38-50/ GPU@54-64 @idle,
    C0 @57/ C1@60/ GPU@71 @3DM06-Freeze
    C0 @58/ C1@60/ GPU@73 @3DM06-Freeze, 450/650 mild OC.
    Amb = 24C, Mobo = A04, BIOS = A09.

    I plan on not using my laptop for a few days until the AS5 cures. I'll be doing more extensive testing then. Those temps are from a cold boot running it for maybe 30-45 mins, then taking temps.
