A pump is NEVER 2.5w and efficient enough to cool a computer. 10w maybe, 15w more likely.
First thing, heat is energy. Second, cpu's produce a ton of concentrated heat. Third, both cooling systems are there to remove this unwanted cpu heat, both having different efficiencies of doing such. A water cooled system will do a better job of removing this heat, thus making temps lower on the cpu die, air cooling does a decent job but isn't as efficient as water. Also, water will ALWAYS add more heat compared to a HSF assembly (eg: a 20w pump will produce approx. 10w of heat + whatever frictional losses). The rad must then remove this unwanted heat from the water loop, and if the cooling loop is cooling the cpu to equal or less than air, it therefore must remove more heat than said HSF assembly.
The quantity of joules simply cannot disappear, especially when more are being removed faster, so your idea of less heat on die heat = less overall temps isn't possible, basic physics determines this.
Also, about the water vs. air thing. It has been beated to death, over and over again.
Cost savings - air
Lower temps (even if tiny) and sometimes less noise - water
To the OP: Dude, wander over to
www.frozencpu.com and take a gander, do some google and see whats the most common setup, and do some research on what you want out of it all, and if you honestly can afford it. Water is a PITA at times, but if done right can be well worth it.
