Has anyone come up with a cheap water cooling solution for the S3?  I already have a nice waterloop built that i'd like to use with a 34" radiator outside.  Hopefully I don't have to spend an arm+leg on water blocks...

what do you want water cooling for?  you can't over clock most of them.  the stock fans keep the gear pretty cool.

if you set freq to 212.5 it is cooler and pretty quiet .  not whisper quiet but decent.

Not sure what your need for a water block cooler is based on.   for all I know  you may have a really good reason.

I have an existing waterloop in my server closet and I'm trying to minimize heat inside.  I'd also like to see how much OC I could get with water cooling.
There is a video on YouTube of a guy in the Far East, making and testing a waterblock on an S1, but I don't know if he ever got enough interest to take the project to production.

If someone supplied me with some current cooling blocks and/or specs, I can design a 3d printable waterblock setup pretty easily and post them up on Shapeways for others to purchase Wink

might be a good idea.  from what I have read the main problem is on the dc to dc chip.  would be nice to have a waterblock solution as a solution

Yeah I've been tinkering around with a couple GPU cooling blocks for my older 5970's as the waterblocks for those are getting really expensive and with the 3d printed metals Shapeways has to offer I can design and print some GPU waterblocks cheaper than I can pay for new on Alibaba or even used waterblocks.

I don't have an S3, yet but even with just the specs I could probably whip something up but I prefer to test my designs personally. I could always design and print the prototypes for a select few to test for proper fitment prior to placing orders on Shapeways (if I don't have my own S3 for development).

Has anyone successfully used the support/message system on bitmain's site?   I submitted a request and every time I login it shows an '*' next to received messages, as if I have a message, but there are no messages showing up. The '*' may just be a weird bug on the site and I just haven't gotten a response yet....

i also get the * beside received messages, and i have not sent a message. its a bug with the site. you arent missing a message back or anything, chances are they are just real busy today with reopening sales and issuing refunds.

okay a good reason.  so far it appears the cooling problem is not the chips but the dc to dc regulator.

Maybe of them don't preform well.  If you can get it to cool well I would think you will get an oc to freq 250 and 504gh

Bitmain are in top gear today.
It seems like they've been crunching hard on shipping out Batches 1 through 3, and are finally coming up for air.

Nice problems to have, and understandable. Onto Batch 4 and beyond...

I ordered 2 s-3's order

price 2x .65 = 1.3 only 1 coupon for .075 was allowed net price = 1.225 btc

They are now giving out coupons?

No, these are refund coupons of 10%. S3 Batches 1, 2, 3 was rated at 478Ghs but it only hashed at 441Ghs.
A batch of DC-DC convertor couldn't handle the higher hash rate. So, bitmaintech refunded 7.7% of the order value of S3.
They also given a default option to get two 0.75B discount coupon (10%) instead of 7.7% refund.
Those are these coupons.

It's probably the 10% coupon from Batch 1 for the reduced specifications.

bitmaintech.com down for anyone else?

It's back up again.
Got me excited for a minute there I thought that maybe they released batch 4.
But sadly no.
