1- If by unlinking you mean make the FSB going higher than DRAM chips, then yes (DRAM 1 : FSB 1.33; DRAM 1 : FSB 1.66).
2- I understand your opinion, but by the way it looks the stock fan it has is very old (maybe 6 years?) and it´s still working good. At least for now.
3- Just in case, don´t get confused with the second version (I945GCM7-L V2.0) of the MB.
4- (If I could just find a video overview of the BIOS the MB has).
Just want to chime in on point #2. That's not an opinion. Intel stock coolers are thermally poor. If you want to eek out the maximum clock speed, replace it. You've already hit a TJ point that's at the upper end of safe for that processor.
The stock fan is not actually the problem in those coolers, it's the material, size and design of the heatsink. It doesn't conduct heat very well.
If you're willing to settle for now, that's fine. But you will probably get another 8-10C of headroom by replacing with a good aftermarket cooler. Did you use premium paste and have you replaced it recently? That might help a little too.
1. No I mean no ratio at all. Linked means the fsb and dram speed are linked by a specific ratio. If you increase/decrease one the other will automatically be increased/decreased as well to maintain the ratio. Unlinking removes the link (ratio) between them and allows one to modified without changing the other.
Your post is kind of hard to read since there are no quotes and the numbers you're using in the list don't seem to correspond at all with the numbered points made in the post that you're responding to.

Compared to a stock cooler of that era you'll get a hell of a lot more than just 10C. Expect more along the lines of 20-30C drop at the minimum.
1- Based on your explanation of "unlink the ratio" then it´s not possible.
2- I applied new thermal paste to the CPU so the heatsink would work better. And certainly it did since the temps were cooler (25 Celsius degrees average, without Dolphin running). I also cleaned up the sink.
3- I noticed something: I lowered the multiplier to 6, then started to O.C. the FSB (I left it near 240 MHz). It summed up 1.4 GHz.
Then I save the clocks, restart and open Windows. For my surprise, the clock speed of the CPU it was registering was the FSB speed, not the one from the cores.
Maybe Windows (XP) had a bug that used to base the CPU speed on the FSB´s?
(I know it sounds very confusing, if you are feeling like that, I´m pretty sorry).
