    I was a bit frustrated :p that no one even Dell can furnish separated heatsink for the new alienware, for me it's not acceptable that some parts are not available for our laptop. i try Dell USA and europe ( i got a home there so i can be furnished ) but any way... my last solution was to mod one from my R3 to be fit on the R5.
    I got 2 heatsink with 3pipes, for my gtx765m, i mod the oldest one, the other one, i think better, i keep it for the gtx780m.

    To mod this, it was pretty easy, just a bit of cutting, that's all, here the result:

    I know, not sexy^^ but it's a beta :p

    Here some temps:

    If someone can share his idle temp or playing temp too with gtx765m, i ll be glad to see if we can see a real difference. As i got more copper pads to come.
    I used IC diamonds 7 as thermal paste.
    My final result will be on the heatsink for gtx780m, with copper and artic silver glue and i will still use the ic diamond as thermal paste.

    Thanks for reading :)

    Thanks for sharing! +1 rep. That must have been hard to achieve.

    My finished Mod heatsink from r3 to R5. I played BattleField 4 on Ultra config with an average of 60fps, no freeze or lag for at least 1hours.

    temp:

    What i used: ( IC diamonds for core and mx4 between the pipes)

    Result:

    I'm pretty happy about the result :) alos the CPU is nice result, it pass from 61 to 59 max with the help of copper pad and aluminium tape.
    Same result for GPU:

    This is before i tape and used the pads:

    Hi, I have checked mine out and this is the results of an hour in Bioshock Inf.: hwinfo.JPG

    This is the fourth one I've had and it runs quite a bit cooler than the previous ones. This was with a mild (680) overclock. I see hwinfo now gives the VRM temps :). These were identified as the hottest part of the card by a guy using a thermal camera. These chips have some sort of thermal putty connecting them to the MB. This is the one I'm using now, as supplied by Dell.

    Hope it helps.

    Seems interesting, what's the Aluminium tape for though? By using a reflective coloured tape you're decreasing the emissivity of the heatpipes, therefore more heat will be trapped within the pipes rather than being emitted to the surrounding area. That's why marathon runners get given a reflective space blanket on finishing a marathon - low emissivity & keeps the heat from being radiated away. If you were to colour them black then you will increase the emissivity & lower temperatures - praps why Dell had them painted black to start with. (Also the layer of glue on the tape will further reduce heat transfer).

    FYI I believe the black painted parts are cosmetic. You will notice these correspond to vents and if it was copper it would stand out when you look at the underside :rolleyes:

    i used aluminium tape as conductivity. It's cheapest way for conductivity as it doesn't worth for an heatsink to be fulled taped with coppers. And i give a try between no tape or tape on the cpu with a copper, it change from 1 degre so i think more myself that aluminium tape was just a cosmetic way too^^
    I don't think so that color is a huge difference for emmision of heat. I think you are confusing dark color as black keep heat and white color as white is reflecting: take a white and black iphone in front of the sun: the black after an hours is burning in your hand :p. Colors don't play in the transmmition of the vibration of each particule. Metal has a better conductivity than wood as example. In order, gold, silver, copper, aluminium have some better proprieties of conduction but a color doesn't have a conductivity proprieties, even not about convection proprieties. So i think so that black was used as a cosmetic way too. Maybe i'm wrong but i cannot remeber having studied heat transmition through the help of color^^. The glue i used has a good proprieties for convection.

    Oh well, your tape & no tape testing didn't show much difference, so it's obviously not having a significant effect, negative or positive. Emissivity, it's not to do with conduction, but radiation, so I'm not confused. Black objects absorb more heat from the sun's rays because they have a higher emissivity, and in the same token black objects radiate & release more heat (when not placed in direct sunlight), which would theoretically aid in the cooling effect. If you look up 'emissivity' you'll see what I was getting at, here's a wikipedia on it:
    Emissivity - Wikipedia, the free encyclopedia

    Either way, it doesn't seem to be having any detrimental effect in your testing you did, so no point in changing it.

    Hmm, yes, probably cosmetic then, especially as the shiny tape vs no tape didn't really make a difference.

    Try taping the air gap of both CPU/GPU fans.
