you sure you want a p4t533-c? IF you're going to be overclocking, don't get it. The fsb only goes up to 150, and with the 2.26, the fsb is already at 133, which only allows for another 289mhz overclock max.
The mobo shouldn't be +5c over your ambient temperature, and the load temp shouldn't be over 50c idle. If you have it within range, you're alll set and good to go. Good luck (not sarcasticly).
