Are these numbers healthy >?

Basicly .. i want to know if these numbers from istat sound right and if everything is ok.

Memory.

Wired - 500mb
Active - 800mb
Inactive - 1.4gb
Free - 1.10gb

(only thing that conserns me is the inactive ... does that mean ram not being used or ... cant not be used?)

Heat.

HD - 33 (deg)
Cpu - 47
cpu heatsink - 40
all three encloser base's - 30
Northbridge - 43

Fans.

Leftfan - 2,000 rpm

Everything looks normal.

My suggestion to you:

Don't pay any attention to sensors like iStatPro and the like.
It will only make you neurotic.

To answer your RAM question, look here: Mac OS X: Reading system memory usage in Activity Monitor

sweet thanks.
