Hi guys.
First - thanks for your input; I imagine many have traveled this road, and probably on a grander scale!
I've been mining for awhile, started with butterflies, moved into R-Box unit and finally mined enough to buy an S9. With one S9, I could vent directly into the same room, and the room would never exceed 22-23 degrees celsius. I pulled the trigger on a second S9, and it quickly got too warm, hovering closer to 27/28 degrees celsius with the HRV running at full capacity with an intake in the same room. So began the march toward ventilation.
I bought:
S9 Exhaust --> 4 inch Wyes --> 6 Inch increaser --> 6 inch duct --> Inline duct fan --> 6 inch duct --> Silencer --> Merge with duct that leads to upper floor in the home (which was typically cold in the winter)
After running for about 45 minutes, the temps on the hash boards seemed decent, running between 72 and 80 deg. The ambient temp (intake) was at 22 celsius. There was this smell developing though, where it smelled like hot plastic. Quick trip back downstairs, disconnected everything, and the fan was responsible. Checking the engineering specs, it has a max tolerance of 60 Celsius. I removed it from the equation, and am now doing:
S9 Exhaust --> 4 inch Wyes --> 6 Inch increaser --> 6 inch duct --> Silencer --> Merge with duct that leads to upper floor in the home
I am still getting a good amount of heat, and without the fan, the board temps are between 75 and 86. Fan speed around 6,100.
I'm wondering:
- These board temps are standard? Haven't much paid attention to them in the past
- Anyone run a similar setup for a fair duration? Worried now, that the little dryer hose connectors are messing with 'something (just being paranoid)
Would lowering frequency allow me to reduce temp?
Thank you -- admittedly a hobbyist! Love BTC and what it stands for.
