[Amps] Using computer CPU coolers on GI46b triode ?

Speaking from the CPU side of things, most CPU coolers cool a CPU that
gives off about 65-135W of heat. Usually not any more than that. Thus,
depending on the tube dissipation, you would need several CPU coolers. Even
if you used a CPU water cooled cooler, they are still rated at about
125-150W maximum.

I just don't see how a CPU heatsink and CPU fan can cool a GI46b at full
power... However that said, a tube can run a lot hotter than any CPU can,
maybe double the temperature. Taking that into consideration, maybe a CPU
cooler can dissipate 250W of heat when running at tube temperatures...
