the PSU will die faster.

add rear fans will decrease air pressure in the box.  it will cause the PSU over heat.

Ng,
What about drilling small holes just above PSU fan to let hot air out?
What do you think good/bad. The holes are small no to destroy aluminum box and it to be able to work as heatsink

he answered some posts earlier, will decrease air pressure causing overheat. the math is all done! I will follow all recomendations.

adding a fans and drilling a holes is completely different thing. So leting hot air out with decreased air presure may turn out to be better

Try air conditioning the room to a lower overall ambient temperature.  This is a sure fire way to reduce heat and keep the units within their design specifications.

front fans press "cool air" inside the PSU. drill holes will reduce the amount of cool air. so the PSU will die faster.

the air blow to PSU didn't go through module heatsink, so they are maintain cool.

drill holes about the PSU will let those valuable cool air run over...

PS: when temp3 is about 50 C, the chip die is only about 65C, completely no problem. not necessary to do too hard, we already over-engineered it for you.

Hello

My stats read:

Code:
Fan1: 0
Fan2: 2880
Fan3: 2520

Temp1:26
Temp2: -1
Temp3:47

However, it appears all fans are spinning. Any ideas?

Does this mean 47 is good or is my chip going to die?

What do you consider the maximum safe temperature for Temp3 for long term mining? Spring/Summer is coming and I'm sure my rig will be consistently over 50C since it is close right now.

It's fine, not hot at all.
The inside of the chip is called a 'die'.
And with these temps you cannot fry your die Wink

Tomorrow the machine will be put on balcony, which is -15 degree for the moment, is there a way to remote login to web interface?

Do you update the firmware while mining? If you stop the cgminer, how can you make sure it will not be activated again by scheduler?

...annnnd it's paid for itself, USD-wise.  33 BTC earned in just 91 hours.   Shocked

A bit more to go to break-even BTC-wise yet.

Well, I just earned 50+ BTC last night solo mining.  Smiley
