Socket A Fan Question?

[MattStone]

Okay I have finally made my decisions. I will be purchasing a 900 Mhz T-Bird, an MSI KT7Pro, and a yet un-named fan. If I bought one now, I could get the CoolerMaster DP5-5G11 ...but it says that it is only garaunteed up to an 850 mhz t-bird. Should I wait since I will be getting a 900 mhz chip, or should I just not worry about it? Thanx for the help.
