Quote:Insolation's pretty much the major energy input for the runaway greenhouse. There's a bit of geothermal activity, but not as much as Earth. (Save for - we think maybe - every 500 million years or so when the entire crust turns over like a flapjack.)
Side issue: How big a contributor is the sun to the Venusian hell-temperatures?
Cutting the solar input will help, since it'll let the planet start radiating away all the excess heat and maybe freeze out the carbon dioxide in the atmosphere. Freezing the planet like that is a process that's measured in decades, though, so there wouldn't be any dramatic change within the immediate Fenspace timeframe.
The only drawback to the scenario-as-written would be the lack of sunlight wreaking havoc on the engineered ecosystem. No light, no plants; no plants, no broadleaf.---
