Heatsink Kits for Antminer S1, Has anyone used these?

[googlemaster1]

I was thinking of messing around with some of my S1'.... maybe custom casing... maybe overclocking and heatsinks?  Not sure... just want to play... but Question: has anyone used these?  Do they quiet the miner?  Do they actually WORK?  Do they increase hashrate?  Please discuss.

That could be interesting. I should note the heat sinks are cheap enough that if they worked, I'd have expected Bitmain themselves to add them and crank up performance a few more GH/s. Also, looking at my Antminer, the production heatsink is on the opposite side of the chips.

That said, assuming you don't screw up the installation, adding a heatsink should be fairly harmless at worst, and it may help a bit at best. I remember reading a couple of guides which mentioned that pointing a fan at the chips can also reduce reported temps by a couple of degrees, though there's no indication of whether that allows for further overclocking or what. I mean, if it's already overclocked as far as the software will allow, and the temp is acceptable, there's no real benefit to dropping the temp further.

Thanks for the quality replies, I probably wont bother and just throw a small energy effecient fan pointing at the outside of my chips.    I keep my miners in the closet with a circulatory fan in there and the door cracked so I mean, increasing cooling come the summer months has been a concern of mine.  (AC Units would trip my already pushed to the limit breakers)

I bought some pink ones for shits and giggles...they are in the mail right now

^ have gone through a couple batches of these for the Ant's DC chips

[Unacceptable]

Got any pics on where to apply these

Thanks!!!!!!!!!!!!

I've ordered a set if these. Will post once they've arrived.

[googlemaster1]

Alright... I might get a set of them perhaps, but I'll play the wait and see game until these folks tell me how they are.  Someone want to post pics and talk about temps or hashrates would be stellar!

Useless for standard OC

Also if u go over 400 mhz, w or w/o heatsinks u still get a lot of hw error

[AussieHash]

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.

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

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)

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.

[precrime3]

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

[googlemaster1]

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?

[AussieHash]

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.

[precrime3]

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

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:

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!
