Heatsink Kits for Antminer S1, Has anyone used these?

[tranzsport]

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


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
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 !!!

Oh, I think I know where you're going with this.. probably overloading the PCB and Voltage regulators in delivering the power to the fans as opposed to the ASICs?
this makes sense bcz heat is never an issue, I run giant fans on either side of my rig to make a tunnel effect and temps rarely ever go above 40c.
thanks for the advice, I will definitely try that tonight and let you know the results!

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.

Does anybody got any experience with this fan?    Scythe DFS123812H-3000 Ultra Kaze 120mm x 38mm

Yep...using them since January...as output fan in push-pull conf...Stock is input, variable controlled by the Ant...Scythe is direct connected @ full speed...and is Quieter than stock...heatsinks on the chips...Aluminum 8mm x 8mm...Cooper 10mm x 10mm on the Volt chips and big COILs...low 40-ies degrees @406MHZ...205-210GH stable...in HOT Florida...

My heatsinks are still in the mail (the 11x11x5 alu), but i got it 3c lower by adding a piece of paper.

Awesome I just try to find the perfect fan here in conjunction with the unit. ( I am in Florida to btw )
So fan I looked @ Delta= To loud and to much amp flow Had the Delta 120mm 3.9A 256 cfm 5600RPM @66dba
Akasa 120/140 x25 Viper R PWN= 109.55cfm on 1600 RPM, It's a 120mm fan but the blades are 140mm @21.7dba
Cooljag Everflow 120x25mm 9 Blade PWM= 110.03 cfm 2400 RPM @39.5 dba

Does anybody finds the stock fan stats? cfm, RPM I know its a 1 Amp To I need to find a slide faster fan (perma 100% power) for Exhaust


Main-goal get it cool and not to loud.

not sure if you checked this before, but this link might help

My stock fans are Delta...131CFM or so   citing from my memory...Scythe is 130 too...but not so loud at full speed...

Digikey is expensive...good reference though...I bought Scythe ..3 for $50 shipped...Amazon or Ebay...

I think that the fins on the small adhesive heatsinks should be oriented vertically rather than horizontally, to improve convective air-flow (doesn't matter if you use a fan to blow on the sides of the S1).
Another option is to buy the 'bare' heatsinks (8.8x8.8x5mm), and purchase the double sided thermal interface separately.  I bought the heatsinks on eBay (AU $1.20 for a pack of 20) and the double sided thermal interface from a local electronics shop (a pack of 2 sheets for AU$12.95 from Jaycar).  This costs a bit lower than the US$16 per antminer S1 kit, but probably requires a bit more work in cutting and attaching the adhesive to the heatsinks.  It is probably safer to shutdown and disconnect the Antminer S1 when you do this rather than risk a pre-mature death for the sake of a few milli-BTC...
There was a temp drop of about 2-3 deg C after installation of these just on the ASICS.
