so ... the overall consensus is that these heatsinks will add additional cooling of about 3 degrees ??

and i was wondering if anyone can tell me if there is a curing time for the heatsinks before the ant can be used again for hashing ??

Thats the problem, its loud. At least for me it is xD

The loudness doesn't bother as much as the whine which a couple of the fans has developed.

Why is everyone buying 1500 RPM max fans and putting them on the rear of ANTMINERs and think they do ANYTHING?     Huh

The fans that come WITH ANTMiners are good for almost 4000 RPM!  I would just trust a datacenter-intended fan any day over this "enthusiast" crap made to OC your i7...

Aussie - have you tried getting a molex to fan adapter and running the ANTMINER fan @ 100%?  If you are having overheating issues, thats one way to fix it!


My Jupiters are in a datacentre, but my 1TH of ants are at home, hence noise pollution is a consideration.  Even in hot weather I don't think i've seen the OEM ant fans go much above 3000RPM.  At that speed I agree the PWM cougar fan is interfering with the air output from the OEM fan (when it was running at 3000RPM).

I originally had all of my ants sitting on the foam base they were shipping on (with the 1" strips torn off).  This stops airflow under the ASIC boards.  

Since adding the heatsinks and Cougar fans, placing them flat on the table 5cm apart, I see Antminer temps of around 41-42 degrees and fan speeds of 2200-2400RPM at 400MHz with =< 1% errors.  (my newest ant only has heatsinks, no exhaust fan, and at 400MHz, is 43 degrees with 2220 RPM).

The Cougars came with optional  molex connectors and I am aware of a OEM fan wire mod to set the fan speed to max.   I've not explored either option.

Overall (in Aussie summer), I think i can keep my ants <47degrees without more than the above (Cougar fans + heatsinks), plus an open window.  Just make sure you don't sit your ants on the packing foam like I did !

I've just been buying the same model my Avalons had for $8:  (and honestly, if you compare an Avalon "module" to an ANTMiner "module" you can tell where the basic layout came from!)

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=201054730658

Not the right power connector but the fan is comparable to the "OEM" ANTMiner fan...  

Think about it this way, that Cougar fan is 60CFM.  That fan I linked to is 130CFM.  WANT COOLING?  GAME OVER.

(and yes, it will be LOUD)

I really doubt those heatsinks do anything.  I added a second fan to pull air out the back and that really helped a lot.  I tried a couple diffrent fans and this one really is da shit:

http://www.newegg.com/Product/Product.aspx?Item=N82E16835553002

Get some #8-32 x 1-1/4" machine screws and #8-32 hex nut for a spacer and your golden.  Without the spacer the fan blades will hit the rivets and I broke a fan blade that way... pissed, it was a brand new fan!!!

I have several of those same fans. They really are nice.

We ended up getting a rosewill fan that came with a grill, so we put the grill between the ant and the fan, and the grill presses into the screws sticking out enough to gap the fan. Not the nicest thing, but it works, is solid, and no broken blades!  Cheesy Cheesy

What the hell!  I was able to get those fans at half the price.... check TigerDirect Tongue.  Woof

Don't know if they help, but the bare ASIC and DCDC chips are too hot to touch normally. With the heatsinks the nearest DCDC and first 3 rows of ASICs are much cooler. When 2 ants are nearby the air leak "wind tunnel" cools a few more rows of ASIC chips with the heatsinks.

I have still seen one of my ants develop XXXX with the cougar fan and heatsinks, without a fall in mining performance.

I haven't OCed yet. what do you guys find to be a good tolerable temp for these things?

Right now my ants are runnning at 45 with 2k fan speed.

These fans work fine (slightly intended) -

That's what I was thinking, hopefully temps stay okay, wouldn't try overclocking it  Wink

I'd say still too loud for a living room. Bitmain's fan is still audible, but doesn't have the "clothes dryer revving up" quality.

Edit : The cougar fans definitely move less air than the bitmain fan, however it may be possible to place front and back cougar fans for a quiet mod.

Thanks for the reply AussieHash.  I might get a set for the Ant I want to put in my living room.  I would imagine that the slower fan speed would result in a quieter operation as well.  Did you find this to be the case?

Where are the DC-DC chips? Also thinking of doing this, if I get 3 degrees lower temps and lower RPM xD

Antminer with heat sinks and Cougar fan applied.
32mm 6-32 UNC screws with a spacer bolt work perfectly

I am seeing about 300rpm slower fan speed, and about 3 degrees cooler at 400MHz


Without the additional fan


The heat sinks. Each set has a large bag of 64 ASIC heatsinks and a small bag with 8 DCDC heatsinks. All come with thermal double sided tape applied. Be careful when placing the ASIC heatsinks as they're "slightly" bigger than the chip top, if you touch the adjacent 4 resistors/capacitors ? The Antminer will short out and reboot.

Would putting these on plus outing a fan on the chips vs on the mounts positively affect temps a preety good amount?

of course it would. the point is, what benefit will you gain by spending the money and the 25min its going to take to stick these on one at a time? (trust me, it will take some time to get each one on, I had to do similar with 112 bitfury chips and it was a pain, but at least allows much more overclocking with a bitfury)

Ive used these sort of heatsinks for my antminer inductor chips to keep them a bit cooler, but the benefit is pretty negligible.

I would advise against sticking one to each chip - you could easily spend 15min trying to do a single antminer and maybe gain a few degrees or 2-5GH

We're experiencing a hot summer down under at the moment. A few of my ants have developed ASIC Status XOXOXOXO which thankfully resolves with shutdown and cooling to room temp.

Heat sinks probably won't be as necessary in cold climates or in a temperature controlled room.
