Hi Kony.

I'm using some Artic Silver putty on the CPU. I think my room temp can
be part of the problem, because in summer it gets up to mid-20's
Celcius. The only fans in my case are:

1 fan on the Abit NF7 motherboard.
1 fan on the CPU itself.
1 fan on my Radeon 9800 Pro.
1 fan sucking air from inside into the Antec Truepower 350W PSU.
1 fan blowing air out from the Antec PSU.

So really, the only fans blowing out from my case is my PSU fan. All
the other fans blow around inside.

As for why I think my system is underperforming:
Test system: AMD XP 2500+ Barton 333MHz FSB, 2x512MB DDR333 RAM, Abit
NF7 motherboard.

My overall CPU Bench 2003 score: 5675
Score of a Intel P4A 2.4GHz CPU: 5758 (note my CPU is supposed to be
equivalent to 2500+)
Score of an AMD Athlon XP 2400+: 5861 (my CPU should beat this!)
Score of an AMD Athlon XP 2600+ (266MHz FSB): 6146

The results are the stored results in CPU Bench 2003, I don't know if
the processors there are overclocked. Doubtful, or the XP 2600+ would
beat my 2500+ by a very long shot.

Thanks.
