62C looks awfully high for playing music and writing emails.  I have a 
Thinkpad T43 (and T40) and it usually stays between 40-50C while doing 
those types of things.  When its building world, I get around 70C and 
usually no higher. 
I do notice, however, that FreeBSD seemed to never use the fan to its 
potential on any of the Thinkpads I've used (T40 for 3 years, T43 for 3 
years).  Comparably, Windows XP would rev the fan far higher than even 
setting 'dev.acpi_ibm.0.fan_level=7' when under load.  The fan can 
certainly work faster (even when booting FreeBSD, its audibly 
faster)...but 7 is the highest level acpi_ibm allows one to set. 

Here's my dev.acpi_ibm on a T43
dev.acpi_ibm.0.fan_speed: 4677
dev.acpi_ibm.0.fan_level: 7
dev.acpi_ibm.0.fan: 0
dev.acpi_ibm.0.thermal: 44 42 33 47 33 -1 24 -1

Using dev.acpi_ibm.0.fan=1 yields similar results, but the fan runs quieter.
