Would AS5 make a difference for my setup?

Assuming my board's thermal diode is reporting the correct CPU temp in the BIOS (and in Everest Home Edition), does any of you think AS5 would drop my temps any? Here's the current setup:

AMD Athlon64 3200+ (Winchester core; ~1.52 vCore; 10x240 = 2.4GHz)
Zalman CNPS7000B-AlCu (~2500rpm, stock Zalman thermal grease)
MSI K8N Neo2 Platinum (BIOS v. 1.9)
1GB OCZ Gold DDR 466 Rev. 3 (2.85V; 240 * .83 = 200MHz; 2.5, 4, 4, 10, 1T)
single WD 36.7GB Raptor
eVGA AGP Geforce 6600 GT (w/ Zalman VF700-AlCu @ 5V)
Antec NeoPower 480W dual 12V rail PSU
Lian-Li PC-V1000 case (w/ front & rear 120mm fans @ 5V)

Idle: ~40 deg. C.
Load: bet. 48 and 50 deg. C.
Ambient Room: ~24 deg. C.

Maybe a few degrees.

Say 4 or 5 deg. C.?

2-3C. I've seen up to a 10C difference.

Thanks. The one time I tried the original AS on my old Athlon XP 1800+ I never really saw a difference. I didn't know if AS5 was any different. Lastly, has anyone tried the ArtiClean Thermal Material Remover? If so, is it worth it or is alcohol just as good?
