My 8RDA+ gave CPU temps of 44C to 45C, with a Palomino-core 1700+ and an Alpha PAL8045 with a Panaflo L1A. That's pretty deluxe cooling for a medium-heat CPU, so if you get 49C, that sounds quite reasonable.
Since motherboard calibration varies wildly from board to board and even changes with BIOS updates sometimes, it's usually futile to try to compare your temperatures to the temps another user is getting unless they have the same board that you do, and sometimes it will still vary depending on the BIOS revision (Asus A7V333's are a case in point).
