Athlon 1.33 cooling questions

I have:
-1.33 GHz Athlon mounted on an Asus A7A266 mobo
-ATI Radeon 64M DDR vidcard
-80 mm inlet fan on front
-80 mm inlet fan on bottom
-80 mm exhaust fan in the rear as well as the PS exhaust fan
-Volcano II heatsink with stock fan.

My system used to idle at about 46 C for processor and 26-29C for the case temp. and about 53-54 C for processor temps loaded when using BIOS 1003b. I recently flashed the 1004 bios so that I could solder jumper 10 closed for multiplier overclocking (I have an old A7A version). The overclock works but now my temps at standard FSB and processor settings are about 9 C higher. I am assuming that the ASUS/BIOS combination is to blame for the temp increase. but I'm still unhappy with a 54 C loaded cpu tmep.
My questions are:

I recently ordered a Swiftech MC370-oa heatsink with the 60 mm delta fan, will I see much of a temp improvement over the VolcanoII?

Would it be wise to install a side case fan (blowing over the processor and chipset) as well as a top exhaust fan, or will this just mess up the airflow through the case?

What sort of case temp should one expect over and above ambient? Right now I'm about 6-9 C over ambient.

How much should the loaded CPU temp be over case temp (with a decent heatsink/fan)? Right now I'm 20-22 C above MB temps.


One last point - I tried a TT mini copper orb, and if anything it performed worse than my Volcano II - yikes.

On some system boards (eg Iwill kk266) temperature increase after flashing a bios sometimes meant that the temperature reading accuracy changed. The actual temperature may not have changed.
