The age old question, is sucking or blowing better?

The standard setup is for the fan to be sucking air over the miners heat sinks and blowing out the hot air. But what if we switch it so we are blowing cold air into the tube over the heat sinks?

With the fan now switched around, laterally unscrew the fan and switch it round, we hear a tone change and the db drop to 74.8db’s

What about temps? well I was actually very suppressed here as we see a further drop in temps to 40c. That’s another 7c temp drop and my office has actually warmed up now due to the miner to 24.8c
