Inaba: Hey, lets do some scientific and procedural testing so we can determine an outcome given a set of constants (hardware) and variables (temperature).
Dalkore: That's stupid. It's either going to be situation A or situation B. I don't know which, and I have no way of finding out unless we follow Inaba's suggestion, but it's still stupid.
Really?
Maybe not stupid, but probably not the best idea. It's more along that lines of "Hey guy who paid for some mining hardware, we want you to stop earning a couple hundred bucks a day from your Avalon so you can spend time doing testing for us."
Right now if intake air temps aren't 85F, why take the unit offline to test that? Worry about it in a couple months when it's getting warmer and there's a couple hundred TH/s on the network, but for now milk that thing for all it's worth. If anyone should be doing this testing, it's the Avalon team.
The air leaves the module with around 50°C. On the same side is the air intake for the PSU, means the PSU gets 50°C air for cooling. Even if it should be just 30°C its not realy suitable. Compare it with the dark blue area outside the device, thats the right temperature.
Jeff, this simple modification will save you power costs
No, the heatsinks are 50C assuming that the camera was properly calibrated to view flat metal surfaces. The air temps are going to be less than the heatsink temperature, looking at the picture it seems around 30C. As you say, 20C would be better but 30C is pretty standard for what a PSU can see drawing air from the inside of a case so it's not like it won't handle it.
Jeff, if you're wondering if it's heating related, grab a couple high flow 120mm fans and put them in the missing holes running full out. You could also make an air guide in the empty slot to force the air from the fan with only module into the heatsink. Both things could be done without having to take the unit offline to tinker with, and they should drop the temps substantially. See if that helps with your restarting issue.
