Alternative Heatsinks for Alienware 17 r1 for a 980m

Hey folks. My journey on understanding how to get a 980m work in an alienware 17 r1 has been a very tough task. Random shutdowns, Random bluescreens, Total teardowns to get the gpu recognized again by the bios, not being able to make a uefi usb, not being able to flash the vbios, etc. Whatever I could have done wrong I did. Well Finally as of yesterday I modded the vbios on my 980m to an unlocked one.

Currently using driver 353.06 from eurocom. Since its basically download and install no modifying anything. I am on windows 8.1 now. I tried like crazy to get windows 7 to work. Using the card with the old vbios let it run in windows 7 but oddly when I flashed with an unlocked vbios windows 7 would stall. Maybe the new vbios needed a fully uefi environment...I dunno.

Ok so here is my dilemma. The card gets pretty damn hot and throttles since I'm using a 75 watt heatsink. I understand the correct dell part for a 100 watt heatsink used on the alienware 17 is yp26v. They are selling for crazy high prices and dell parts doesn't seem to have any more of them.
is it possible to use a 100watt gpu heatsink from a m17x r3 or r4 in my alienware 17?

if anyone has tried this or knows of working alternatives please do chime in. thank you

As a secondary question what would you guys use on the 980m? gelid gc-extreme or coolaboratory liquid ultra?

 

Do you mean AW 17 2013 version?

 

yes im referring to the AW 17 2013 aka AW17 R1 now since there is now a r2.

 

Why are you getting it from DELL, Eurocom sells them brand new for 86$ and needless to mention that when you sell your heatsink this will bring the cost down even more

If you are a brave soul you can go to a shop that can make you an additional copper pipe and weld it to the heatsink you.

On some German site a guy runs his processor using 4 pipes heatsink, he simply welded 2 pipes on his CPU heatsink.

EDIT: Found you the link http://alienware-forum.de/index.php/Thread/7254-AW-17-R1-CPU-Heatsink-Pipe-Mod/

 

That is really amazing!!!!!!!

 

The guy runs the CPU @4.1 GHz and it remains below 80c

 

Without fan mod? So cooling limitation is still on the heatsink.

 

Actually I believe right now he is limited by the whimpy fan ... With a better fan maybe the M17x-R4 the impact will even be much better ... I am planning on doing this mod when I have some free time

 

With default fan and heatsink, can 4910mq run without throttling (with better thermal paste like MX-4 ) ? I also want to add pipes but I really don't know how to weld.

 

Mine reaches up to 9400 physics on 3DMark11 using stock clocks, stock fan/heatsink with undervolt of -50 mV & Gelid Extreme TIM ... Also, I was getting up to 9300 with Zalman STG-02 TIM

That processor never throttled and never broke 80c ... But that's running stock, I believe on a heavy OC it will both throttle & heat up significantly
