As I said. DON'T go full 400Hz. Look at mine it hits 200GH/s but low Hardware Error % and good Temp and don't for get the Heatsinks for the Converters (Total of 8 )

may I ask what hex code you're using for 393 MHZ ?
I tried '5f82' but got 2.5% on many of my machines, but going for 387MHZ using hex code '5e82' seems to give me 0.5% error with 3 Ghz less total hash output. This seems to be consistent across atleast 10 of my S1 ants

I am still a noob XD but I played around alot. Those settings are the best for speed and low HW Error % Rate
Maybe as a return you can help me to find a fan. 120mm 100-130 cfm by a lower then 50 dBA with max 1.05 Amp Put my Delta on the unit via direct power-supply gets the antminer down to 37 C.......but plus 4 Amps @65dBA. That is the noise level of a industrial floor cleaner.
BTW NEVER EVER put that thing on the Blade....EVER 4Amps pulls 45 Watt. So I assume the blade will burn off. Just a guess never tryed it.

Jomant's Magic Settings for 200 GH/s and a Hardware Error Rate of 0.69 %
Tip me some BTC if it works for you Wink

option freq_value 5f05′
option chip_freq 393.75′
option timeout 36′

tried these settings and got the same error rate as my previos hex settings Sad

maybe its my miners.

but regarding the fan,
I use the stock fan as intake and a delta AFC1212DE as an exhuast on the other end.
you get the same results if you use the stock fan as exhaust and the delta as intake.
Just make sure to cut the blue wire on the additional fan you buy so it runs at full speed the whole time, otherwise it wont properly sense the voltage coming from the miner to adjust rpm.

the delta is 51 dB with 200 CFM and uses 1.3A @12vdc so no big deal taking that power from the board. I have 25 ants with these fans as exhaust running for at least a month with no problems.

you can find it for $8 shipped on ebay just type in AFC1212DE

Ahh ok I got the TFC1212DE @3.90A yours pulls only 1.6A what is awesome due to that it produces good pressure. Cool
About your issue:
I use a 650W power supply and got the heatsinks for ASIC and Converter on as seen above. What is ur temp?

Ohh PS do me a favor and unplug ur delta and hook it up to direct power from ur power supply just to see if the 1 extra amp less fixes the issue.

If you have TeamSpeak and a headset let me know. I am not to shy to talk to people !!!

Please do. I know that the common max for PWM Headers are around 1 Amp. The fan may parasite's the amps away from your chips. Each board got it's dedicated power inlet but the Delta got Amp Stats above 1 Amp plus u let the Exhaust run full blast anyways so no reason to let it control from the board. (What is a plus anyway exhaust need always to be faster then Intake otherwise you get Back-Pressure due to Air flow resistance.
