    as been said , the 780M heatsink is more then enough for the 980M
    as for the second part , i'm very interested in knowing the answer for that question. ( MOSFET's)

    I know they are "enough" but under load, or overclocking etc, it is not ideal. Besides a 780M Heatsink goes for 20 bucks on eBay. Its more for easy swapping without reapplying thermal paste, pads etc.
    My question was whether the AMD heatsink was a better fit than the 780M heatsink, and whether it needed to be modded in a similar way for optimal results.

    Best fit will always be the heatsink designed for the 980M

    You need the amd one! That’s fit properly, the gtx 780m one if its the same of the gtx 880m heat sink, will flex on vrm

    Hello.
    New in the Forum here.
    I'm going to upgrade my 18 R1 sli 765m with one gtx 980m.

    I've already bought the 100w heatsink.

    Any version of 980m that I find will work or does it have to be with Dell vbios? Throttling problems with any bios?
    I've found 980m's with different year of manufacturing dates. Codes that initiate with 14, 15 and 16 (2014, 2015 and 2016 I guess). Any one will be good to go?

    I play occasionally, but since Sli is getting abandoned, I'll stick with one 980m.

    Is there anything that I have to know to make the upgrade?

    Sorry to invade thia thread, but didn't want.to open a new one..

    Thx in advance.

    Just doesn’t make sense at all nowadays getting an gtx 980m. Just there are gtx 1060/1070 mxm, gtx 1060 has already better performance than gtx 980m. Lower power, cooler and quite

    But for the 1060 mxm, do I have to use a modified Bios for the laptop?
    The driver must be modified to right?
    And the heatsink for the 1060m. Wich version works with it?
