it doesnt matter about the lamp used, the wattage is the amount of power the device consumes, not what you feed it, the only limit is the maximum that can be fed to it. for instance a 200w transformer can still power a 10w device so long as its at the same voltage (and frequency).

anyway, if your putting 172w of heat into your system, you may need another heatercore, but it depends on how much your heatercore can handle. see if you can find out how much it can disipate, and how to work out what it disipates defending on the cfm of air flowing through it. that way you can keep the water at ambient without excessive fan noise.

a second heatercore is allways a benefit imho, it just adds that little extra.

Overkill = Overcool = Overclock.

that would make a nice sig.
