Looking for a good P4 cooler

[scorpi141]

Hi, I have P4 2.53 Ghz and MSI 845PE Max 2 FIR 6704 Mobo. I'm a bit worried that the temperature of the CPU is about 40C-45C, so i'm looking for a good cooler. I was thinking of Thermaltake Dragon, but might be there is something better avalible right now.
