Asus probe really does report the processor at 25° right now so I hope there's some explanation to this. Again, I don't like it when things don't work properly...

The zero ex bit is part of a few design changes that make the processor more economical with it's power consumption. AFAIK the new 6xx series uses that. So your 530 shouldn't have it.
25C for a P4 530 is low, very low. Perhaps it's because your cooler is running at full speed? That'd explain at least part of it, especially when combined with a *lot* of extra case fans. In a "normal" computer case, with normal cooling, a 530 should run hotter. Hell, my own 2.6c, which is known to be way cooler than the new P4s (like yours) runs at 30C, in a 20C room. In my experience, the newer P4s (Prescott core) should run 15 to 20 degrees hotter than the older Northwood ones (mine).
I suggest that you use some other means of getting the CPU temperature, and compare that with the Asus' reading. Or you might want to try a program like "speedfan" or "motherboard monitor", to see if it's the Asus Probe program that isn't working right.
If you want some other option without having to install/buy anything: turn off your computer for 30 or so minutes, turn it back on, go into the bios, and look at the readings there. If it reports 10C or something like that, you'll know it's wrong.
