Best cooling for taking 3.2E to 4Ghz?

[gazorp]

Hello Pros!

I recently got my grubby hands on a shiny new pressy 3.2E for a new system build. I already ordered and received my ASUS P4C800E-Deluxe, and will be using my trusty Corsair PC3200XLPRO for the memory.

I also just received a beatiful case from silverstone, the TJ-06. [REVIEW] I will be doing custom window mods for the side and top blowhole. I plan to use the dual 120mm blowhole as the radiator mount/shroud/exhaust. (pics coming as available).

I currently have a great watercooling setup with a supra heater core, fusionHL and a TDX. Problem is the TDX is for athlonXP and not P4.

Since i have to upgrade the CPU block anyway, i figured why not go for the gusto and jump to TEC. I am strongly considering swiftechs offerings in the MCW5002-PT and the matching MCW50-T for a 9800XT.

My question is.... Is this block (properly powered with a meanwell) sufficient to get to 4Ghz, or will it require a TEC upgrade, OR should i do something else even crazier ? Will my HC (with dual 120mm fans) be sufficient?

As a side question, is there an easy way to control voltage a FSB with a p4 setup like this from windows? I would idealy like to "Crank It Up" to 4GHz only for games, and otherwise let it idle at stock settings.

Thanks in advance!

Depends on the CPU. Maybe air will get it to 4ghz or maybe it will take a phase change setup to get below 50C. The overclockability of a CPU is not all that predictable. Maybe try overclockers.com and your spacific CPU stepping s to see the luck of others.
