I serioulsly hope that you havent bought your cpu or heatsink yet.
I would have to advise you from buying the Jet 7 it really is quite freaken I cant hear you loud. I have its sister cooler aero 7. I couldnt mount it in the floppy bay without having to mod the stupid thing with a drill and such. I ended up putting that loud thing on my 2200+ and turned the fan speed way down.
Also unlessare talking about the clock speed of the processor which would be 2.2ghz roughly for a 3200+ which has a barton core. OR do you seriously mean the 2200+ which runs around 1.8ghz. Cuz the 2200 is extremely difficult to overclock.
But if its the 3200+ you are talking about, go with it. I managed to overclock that sucker to 2.5 ghz by just increasing the bus speed. Make sure you have good ram for that though.
Cmon, just say it aint so, the Jet 7 is no good. If decibil levels are not an option then go with something else. Check out http://www.frostytech.com/
they are the best with heatsinks.
