Do not pay attention to it Wink
Up to 25 c room temp you are ok. You will get used to hot heatsink. If yo don't like it reduce clock power and hasrate

That one Fan on the top is EXTREMELY noisy Angry

Beastlymac and dozerz are looking to buy if anyone hates the noise! I did warn you about Sunon Maglev 4500rpm.  Wink

Did you get finger guards? If not, be very careful, these are industrial strength fans, can take the end off your fingers!

I'm gonna replace the fans and run it at a lower clock, if mine ever arrive.

What are good settings for 200GH? Will these A1 run at 1GH/1W there like Bitmine's A1?

This settings are not working after ~10min, but I guess it depends on my current PSU.

I was wondering about putting a slower fan on the top of the miner and two 120mm on the sides to get an air stream.
What do you guys think about this? I guess it would be much more silent than my curretn 80db  Undecided

Where the heatsinks aligned like this = or this +?

If they were like this = I was going to build a wind tunnel and put a 120mm fan at one end and blow air over both heatsinks.

But last I saw Marto changed the heatsink design to +. For that configuration I was going to put 2x 43cfm 92mm fans on top with cable ties.

LOL... I know you meant 2500-3000RPM, but the thought of a 3000W (4HP) fan made me smile.

Something like that, 49,000CFM.

Oh no! Please don't give Marto & Zich any suggestions for stronger fans! They'll use them! GH to the moon, just needs faster fans! Cheesy

Shhh! Don't mention the Delta 92mm/4800rpm/110cfm!  Wink

Yeah the heatsink air flows are in a cross + so you cannot use a wind tunnel to cover both heatsinks with a big fan.

Can you measure the length of the heatsink and see if it's 184mm long.

2x 92mm fans on the top was my next idea, depends on length of heatsink though.
