It *is* a bit high. Not ridiculously so, but a bit high. I have
an XP 2000+ running at 133 MHz FSB; my typical idle temps are around
49C, and I've seen it as high as 57C.
First of all, assuming that you're in the domain of tweaking and nothing
is flat-out wrong (that is, assuming you put the CPU heatsink on correctly,
used grease, assuming your fans are working, etc.), the first factor to
consider (especially if you're in the northern hemisphere right now) is
the temperature of the room. In order for your CPU's heatsink/fan to
adequately dump heat to the air being pulled into the case and circulated
out, that air shouldn't be too hot to begin with. The hotter the air in
the room, the harder the CPU finds it to lose heat, so the warmer the CPU
gets (raising the heat loss rate), until the heat loss rate *does* equal
the rate of heat production, or until shutdown or CPU meltdown or similar
bad outcomes. In my room temperature going from 22C to 27C, I've seen my
CPU idle temp climb from 49C to 55C. You don't have to refrigerate the
room; but it shouldn't be *too* hot either.
Assuming you're not keeping your room too hot . . .check your case fans.
Not the CPU heatsink/fan, but the intake and exhaust fans mounted to the
case. Make sure they're running OK. Consider adding fans if possible
(my setup has a side intake fan to add to intake from the front, and two
rear exhaust fans in addition to the power supply fan.
Assuming you have good fans for intake and exhaust . . .consider rounded
IDE/floppy cables, or bundling the ribbon cables you have together.
Unbundled ribbon cables seem fairly effective at blocking airflow inside
the case.
Finally . . .are you sure you're OK with your CPU heatsink/fan? I don't
know the whole Zalman lineup, but my understanding was that Zalmans are
nice and quiet, but not that hefty in terms of cfs. An XP 2500+ has
some pretty strict heat dissipation requirements, and so you have to be
extra picky about the heatsink/fan that you use. You might with stores
that build systems with XP 2500+ CPUs to see what cooling systems they
typically use.
Good luck,
