Yes it's normal. The 110 MHz MicroSparc-II CPU's produce a lot of heat.
That's probably why Sun never put the 125 MHz versions into production and
decided instead to offer a 170 Mhz Turbosparc-based system board as another

There were also 160 and 170 Mhz 'retrofit' kits to add a Turbosparc CPU to
SS5 system boards which had the Microsparc-II CPU socketed. Not all SS5
system boards had the CPU in a socket so that's probably one reason why the
retrofit kits fell out of favour (and I haven't come across any for some
years now).
