You can just go onto ebay and search for "e6440 dgpu fan" and the whole heatsink plus fan assembly is like 12 dollars.

No, but it's the most common, probably has the best warranty and is most cost effective. There are better msata ssds but they are expensive.

I'd probably look out for an 850 Evo msata ssd. 840 is an older version

Google "e6440 Repair Manual" and download the PDF from Dell's website. Read through it. It's I think...7 screws to remove the heat sink, a twist ofn an 8th screw and the CPU is out. Clean both surfaces of the heat sink and CPU gently with 90% iso and apply thermal paste and reassemble. One great thing about business class laptops is how easy they are to work on. I'd buy what ever one you can find for the cheapest you can find, and then buy the parts separate. Then again, you might just get a good deal.

Can Confirm, was getting sata 3 speeds on my 840 evo before I sold it.

Hello Everybody Just got an e6440. I am wondering if it is possible for me to add wireless video capability to it by carrying around something to connect to a TV or monitor. Miracast or something like that. I notice it has two WiFi mini card slots, can something be installed there to facilitate this? Thanks!
