ASAP CPU cooler advice

[Crescent]

I want to overclock my cpu more when I need and run my pc quieter when I sleep. Now it's on 3.17GHz stable, but when I put in on higher voltage then the temperature while iddle rises to 50+.

I have only three options avaible here:

Coolermaster RL-MUA-E8U1

Coolermaster Vortex TX

AKASA AK-961


I need urgent adivice because shop closes soon

I bought AKASA as for now. In anyway I prepare financially for big change - changing to some performance ram, Pentium 4 950, Nvidia 7900GTX, Physix card, and some good modular psu. Everything water cooled by - and here I didnt decide yet - some kit.

Is ther any watercooling kit (up to £200) that will have gpu and cpu cooling in the kit?

It's amazing. At 3.0GHz fan speed was ca. 750 rpms to keep it @ 40 degrees. When I overclocked to 3.2GHz temperature raised up to 42-44 and fan is still at 750 rpms...
Which is unbelivably slow compering that my old one to keep cpu around 42 degrees at stock speed needed around 1400 rpms...
