I rarely chirp in but I do as many "power" computer users do & that's
"water cooling" on my computer. There's a large market for these kind of
heat sinks & in short what is done is to have water replace air as the heat
sink cooling media. An in-line water pump pushes water through the
"water block aka heat sink" and it's cooled remotely by a 120MM fan
blowing through an automotive heater core.
Water is far more efficient than air for cooling so you get temperatures of
about 4 degrees C maximum over ambient room temperature from a
processor running 80 watts.
Yeah... I know it's too much for most people to deal with & no, you don't
get water inside your equipment... but your computer is dead silent
except for the sound of the drives. If you were to do this with a radio
it would be the same, no fan noise.
Do a google search for water cooling on computers & you'll enjoy the read.

Also, if someone knows the whereabouts of an Alpha 77SX with the serial
2931 it's mine & I want it back. I sent it to Alpha when it was owned by
ETO & it was never returned after they moved from Colorado Springs.
Yes, I have all the documentation.
