Thanks for the tip! Picked up an STC 1000 to arrive on Tue. Also, have a cheap thermo-mechanical thermostat for $6 to arrive on slow-boat from China. The refrigeration unit of the 1.7 is capable of doing sub-zero. My thermo is definitely shot, so i bypassed it and it got down to -1.

I think that will work fine. I put vinyl flooring on top of my foam floor in my huge (60 gallon in 4 60l spiedels) chamber powered with a 3-4 ish cf mini fridge.

If you can, I recommend picking up a usb powered (12 volt) case fan with or without speed control and sitting it in the freezer section of the mini fridge (freezer door removed) if it has one. I use one (always on unless racking) blowing through the cold plate freezer section and my whole chamber stays within 1* F. I put the actively fermenting spiedel next to the fan/fridge and move the more advanced ales down the line as it were.

The summer temps in my garage regularly get into the high 80's degF. Thanks! - Jeff
So how did it turn out?? I just received a the same 7g Chronical for Christmas (its arrived already!) and have a 1.7 cf fridge. Didn't think about raising the fridge, not sure there is that much need for a small chamber?? I also have ordered the small pc fan and will install in the fridge, not sure if I will run all time or just tie in with the cooling. Any thoughts? Am thinking of a heating pad for warming as needed. My basement temps run 55 in winter to low to mid 70s in summer, so not a huge range. Will also use the 2" solid insulation as well as remove fridge door. Controlling temps all with a STC 1000. I can't wait to take to the next level with controlling temps, have made some great beers, but looking to always improve!
