Temp Problems, 45c Idle, help!

[Operaghost]

Not that there aren't a dozen of these posts a week but I can't figure out why I'm running so hot.
My 2.8c is running at 45c idle.
Case temp is 35c idle.
Both of these are reports from MBM 5
This is at stock Vcore voltage although it is running at 233 FSB.
Since my Abit IC7 Max 3 doesn't report very reliable temps, nor is checking in the BIOS an accurate way to check under load I opted to try MBM
Is MBM at least accurate within a 1 degree C or so?

I'm going to clean/re-apply AS5 to the HSF after I post this.

My cooling otherwise is as follows:
CPU HSF - Zalman 7000Cu
NB - Zalman NB-J47 Passive Heatsink
2 x 80mm Adda fans (intake) approx. 25 CFM
1 x 80mm Adda fan (blowhole) approx. 25 CFM
2 x 80mm SilenX fan (rear exhaust) approx 28 CFM

As a sidenote, one of my intakes blows directly across my RAM modules, then across the CPU. Although they don't move very much air.
I'm thinking that maybe I just need more airflow but something is telling me that isn't the case. My case is very clear of wires, there is a good path for air to follow, my fans aren't super powerful but they placed smartly and are free of obstruction.

MBM will only report temps as accurately as the motherboard reports them to MBM since that's where it gets them from. The system in my sig reports 41c-42c idle, and 45c-47c load (watercooling).

More airflow won't hurt!
