Silencing my beloved work horse - P3 1ghz + CUSL2 + 8500

Hey guys!

I got my cnps6000-cu yesterday (that's before reading on this site). While it is okay for the money, I want the cooling to be better. It's been raining and it has been cold. Here are my results:
Idle : 34*C
Load (with Prime95 overnight) : 49-51*C
This was in silent mode (it is indeed silent--although the drive, psu, and Radeon 8500 fan could be masking noise from the 'silent' fan).
is this acceptable? or should I go for SLK-800?


My system configuration is as follows:
Asus CUSL2 mobo (no fan)
Generic 300w DR-300A power supply (about to change to either zalman or seasonic ss-300fs) -- need your advise
Pentium III 1ghz 133mhz fsb (currently cooling with CNPS6000-CU but about to change to SLK-800) with either panaflow or papst fan. (unless my readings indicate adequate cooling).
ATI Radeon 8500 128mb Retail (non-LE) - this is the main noise generator right now. I was thinking of Zalman's ZM80A, and was wondering if anyone else tried that yet. This card does have that hole to mount ZM80. Is that the only difference between the two (ZM80 vs ZM80A)? I thought ZM80A had better cooling capability.
My drive is WD1200JB (120gb 7200rpm 8mb cache WD SE drive) - should I wait until seagate barracuda V 120gb with 8mb cache comes out? or enclose it in smart drive?

Any feedback will be greatly appreciated. Please feel free to recommend or de-recommend any of the product for my system. Instead of upgrading my system to P4, I've decided to make it quiet, so I have okay budget set aside for silent cooling. Thanks guys!
