Topic: Heatsink Kits for Antminer S1, Has anyone used these? (Read 7545 times)

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.

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...
 

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

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. 

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

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...

Phobya Thermal pads...0.5mm

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

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.   

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!

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 !!!

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

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′

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

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 )

Man Jomant, now I really want to get these again... I almost forgot about them.  I am about to overclock my Ants since they are out of warranty now anyway

Here the Update after overclocking and adding Heatsink's to the ASCI Chips (64) and the Converter chips ( 8 )

Due to my config I only get 0.69% Hardware errors and stay @42 Degrees C  

Here again the Error rate Formula: Error % = HW / ( HW + DiffA + DiffR) * 100

PS: Not a Delta Fan connected wait for my 50W controller but with the stock fan and a cheap 120mm out of a old Tower I get down to 42. Guess for -3 degree with the delta it's not worth it when I see people OC temp of close to 50

I worked on Z10 IBM Server Racks and I can tell you this. Exhaust fan always faster then the Intake for best performance. This is not a cute PC tower. Cool that thing like a Server. So try it out. Here the outcomes!

Stock fan intake with Mickey Mouse 1000 rpm fan as exhaust= Fast fan goes to 2-3000 rpm 1000 rpm fan can keep up and gets speed up by stronger air flow. There we have back-pressure and heat stays longer in place + pressure resistance for the faster fan. Just give it a shot and try it out. Use a external thermometer for the measurements.

2 the same fans can work great but on the long run the exhaust will work harder due to Pressure turbulence from the first fan (thats why ships have there propeller offset.) Due to previews sentence is the Lifespan of the fan lower, when the exhaust slows down due to that fact you will have the same issue in example 1

So I am new to the Bitcoin world but I needed to tell Business owners that they need a new rack due to overheating caused by a know it all programmer (I can't programmXD btw) replacing a exhaust fan what looks like the oem fan but was a 2000 instead a 4000 inside a closed IBM Z10 Paraboard Server Housing. The replacement cost $24.000  (that's the insurgence price. So you guys teach me overclocking stuff and I help u to keep ur Hardware alive

ohhh I like the heatsink idea btw. Notice to at the first pictures that he aligned the fins towards the flow. I seen some nutcases putting them up.
I received my s1 in the mail couple  days ago. Still run the stock fan no OC work don't to it. I have the German designed Cougar fans as well but they blow from the side in a 45 degree angle from the main fan side aganst the blades. I ordered some Alu heat sinks (cooper is better but heavier as well and i dont trust the thermal glue stuff that much.) My future setup (in the next 3 weeks) is 2 Delta Fan's (they are very LOUD!!!). 2 the same fans but intake speed reduced by 25% where the Exhaust is hauling full power.

That will be a 60 dBA Setup but its the best cooling u can get (besides water or liquid nitrogen XD)
So don't put that in your bedroom. http://www.cwc-group.com/pfc1212de.html
I put mine in the storage room (almost empty with ac vent, live in super humid hot Florida)


 

If memory serves me well, copper is better for transferring the heat, while aluminium is better to dissipate the heat.

So therefore wouldn't copper heat sinks be better for this sort of applications?

I also live in Australia and fark me its been BS hot. So upon ordering my Antminer S1, I've been looking on ways on how to cool these beasts down.

All the forged copper heat sinks sizes that I can purchase within Australia are:

6.5mm x 6.5mm
10mm x 10mm
and 14mm x 14mm

http://lib.store.yahoo.net/lib/sidewindercomputers/bmrc1.jpg

now according to the specification listed, the physical dimensions are as follows:

The BM1380 chip is a QFN 56 with an overall dimension of 8mm x 8mm
The VRM is using IHLP5050 which according to Vishay is 12.9mm x 13.2mm

The main question I ask to other owners

Is there enough spacing between the asic chip and the capacitors to fit a 10mm x 10mm (given the copper ones are 0.6mm overall bigger than those ebay ones), hopefully this can be rectified by using 1.5mm Phobya Thermal Pad

Is there enough spacing between the VRM and the F12 capacitor to fit a 14mm x 14mm as it is overall 1.5mm bigger.
 

I want to know if anyone measured a power drop from running the VRMs at a cooler temp? Ya? Anyone? 

I put the heatsinks on whilst hashing. However just be careful not to touch the surrounding capacitors?/resistors or you'll see your Antminer short out and reboot.
