American fridge freezer conversion?

[clarets7]

Our 4 year old AFF has just been declared a write off by the repair man (insured luckily), compressor blown and melted plastic at bottom of the fridge. Seems a waste to send it to the skip, I can get two 30L fermentors in the fridge side with room to spare as well. I've got two 90W peltier cooler modules I bought a while ago, the question is will this be enough for the cooling side of things? The fridge capacity is 346L, about 12 cubic feet. I mainly brew bitters, but also the occasional lager to keep the wife happy, so would need to get down to 12C for those.

Has anyone ever used these in this way?

Thanks,

Jonathan
