X2 3800+ STAYS AT 30-33C WITH 5220 rpm fan

[musicman53]

Hi,
regardless of my cpu fan being one that will run at 5220 rpm(flat out), or one that runs at 2400 rpm flat out the temp stays the same(while not really doing anything)and at around 45-55c under load.
Anyone have any thoughts on this?

Using Thermaltake StreetFighter fan on A Silent Boost all copper heatsink
at the min.
Case temp is around 36c.
Have an Akasa 120mm 1500 rpm case fan(extracting)
Changing to a SilentCat(92mm)Thermaltake(2500rpm)soon and a Silentcat 120mm case fan(extract).
The Silentcats are Panaflo's.

Nothin in the way...
also even if the side is left off of the case then sys temp(case)shows as 36 ish still.
