Which screwdrive will remove the heatsink screws in the Mac Pros?

I'm considering upgrading the CPUs in my Mac Pro. Does anyone know which screwdriver will remove the screws that hold down the heatsink? Thanks in advance.

you need a long-handled, magnetized 3 mm flathead hex

This is what I used. It doesn't need to be magnetized like it says in the service manual because the screws are captive. The first time I tried to remove the heatsink, I had a bunch of socket extensions connected with electrical tape. I decided that there had to be a better way so I bought a hex tool like the one listed above. It is intended for idle adjustments on BMWs but it works great for removing CPU's from Mac Pro's.

That was exactly what I was looking for but couldn't find on my own!

Thanks for both your help!
