Well apparently there was a power outage over the weekend that I wasn't aware of. Perhaps that has something to do with the issues. Either way on a whim I shut everything down and plugged the second Chili back in and for the past 45 minutes now they've both been cruising. I do find it interesting that when I was just running 1 it ran about 3GH/s faster though. Will they dynamically adjust their speed in response to a power shortage? Or to put it another way - is it possible/likely that the Chilis have the ability to run at a slower speed if they sense they aren't getting enough juice to really push things?

It shouldn't be a heat issue - one is air cooled and the other is water cooled and they're positioned in such a way that they shouldn't be sharing any warm air.

My chili's at 38Gh draw 220watts
The bottom end units run at 33Gh draw 180watts

one with defective engines runs at 23Gh and 140watts.

If you are getting 39Gh then all your chips are good ones and running at top speed, (the power draw will be a lot higher than 220w)

The chili's will run anywhere between 23gh and 40gh depending on the power available. The voltage will regulate to meet this level.

Much below 23gh the power supply stays below its critical voltage and will crash.

4 chilis working stable ( even been Lucko's boards ) since an 1 month and half on coolermaster b700. no aditional load.
Only issue: power cables temperature is 55 ºC ( so somewhat hot.. ) at connectors. I think power will be near 150/180W but Haven't mesured yet consumption at power cord.

For me chilis apears not sensible to small power fluctuations but hashing seem very sensible to room temperature.
Today total 143 GHS 131 GHs at pool 25,5 ºC room temperature. I have got in some cold days 145 GHs.
If room temperature is below 24,5 ºC i have a big trouble to maintain a stable setup
regards

It´s absolutely the same I have seen for weeks now - lower room temps are really a pain for start hashing.
When they start hashing - they finally run stable. I too have some boards what are starting everytime on 15 °C without a hairdryer.
