I'd like to install the best heatsink/fan (HSF) assembly into my X61s and have torn it down
completely. The assembly looks quite small ( FRU 42X3804) and based on these posts I believe
that the larger fan from the X61 will not fit:

My first question is if the bases for the X61s and X61T are the same dimensions so that
whatever is required for the T is also required for the s to use the larger HSF assembly? I've seen
mention of case mods that allow the larger HSF to fit into a T, can I assume those will also work on
an S? Anyone know or have a picture of what those mods are?

I might just buy an X61 for the larger case and fan rather than hack up this s type.

Is it true that all the motherboards fit dimensions wise between the X6X, T and S types? I understand
that a standard voltage processor would probably not cool properly in the slim chassis.

HSF part numbers that work and are the best would help if anyone has them handy.

I replaced my X61s base cover with the X61 part to fit the larger fan. The X61 fan will not fit directly into an X61s.

Here is my solution:

I took a heatpipe from a not working fan and attached it using permanent heat grase.

It has improved the heat level a bit. I haven't done detailed comparison though.

vavet,
That's a nice mod.

Thanks people, I'll probably just buy the bigger one and see what it takes to
make it fit or else use the X61 bottom.
I'm also shopping for a t8300 motherboard so perhaps I should just switch
to the X61.
