This week the farm has made some progress. I have managed to have it running for 4 days straight, but today was a bit warm so had it shut down during the day. Being the evening and a little cooler its running again. The thermometer on the top of the shelving unit is saying 28 degrees at the moment.
A new version of the Astropulse application was released last weekend, so i'm running the cache down to clear out all the Seti work and will install it on all the machines once they have cleared their current work.
