Hi, I have 4 aluminum radiators of 250x132x40 mm (about 9.842x5.197x1.575 inches) each, which weigh 1673 gr (about 3.690 Lb) each, are sufficient for the 20w version? Adding fans could be used for the big boy version?

Hello my name is Antonio. I live in the south of Spain, in Malaga. I'd like to do an alpha BB. Although Maty already warned me that produces a lot of heat and here where I live 15 degrees in winter and 30 or 32 in summer. That HP radiators with fan I recommend to cool as much as possible and not make a lot of noise. My level of English is bad, if you do not understand something of what I say is by the translator of Google.What radiator do I buy? To remove the maximum heat possible. A greeting

Antonio,

Welcome to the ALPHA thread!

One of the minds behind the ALPHA BB, xrk971 uses the cooler described (with link) in this post:

Maybe X can chime in too.
