No.  It has parts that dissipate a lot of heat, which will require a
running fan to get rid of sooner or later.  It is made to be reasonably
quiet, which is not the same as being silent.

The X61 uses a normal CPU.  The X61s has a ultra-low-power CPU and
therefore can go longer lengths before it has to start the fan.

And you do NOT want a X6x thinkpad with a WWAN card if it means a second
fan.  You will also want to disable WLAN (in BIOS even, if that will
hide the PCI device.  Otherwise, rfkilling it should be enough).

Operate the 'to be silent' thinkpad using wired ethernet, at 100Mbps
(1Gbps dissipates a lot more heat).

Note: it wouldn't be enough to disable WWAN on a X6x notebook that has a
second fan just for the WWAN card.  Both fans would start at the same
time, regardless of WWAN being operational or not, so it would be less
quiet than a WWAN-less notebook.
