To save your space and improve working efficiency of multiple miners,Syscooling launched this watercooling kit:SC-BC2 watercoolingkit.It could perfectly support 4 BITMAIN C1 miner,and max power of heat dissipation is 3500w,you could also apply it for other miners with total power less than 3500w.Haven't received any negative response by now,extremely stable and efficient.




Surprise:customers post using experience with pictures here could ask for extra refund ranges from 0.01 to 0.1 BTC!Not sure  how long will it last,what are you waiting for!

Do not buy from any electrical things. An awfully long time to RMA.

EDIT. 21.01.15
Excellent kit. I now have one of these.

Do you have any bad experience about this watercooling kit?

I have only bad experience with your company attitude to clients.
If I would have paid with PayPal and asked for a partial refund, I would not have received such other than empty promises.
Even today, you sending a DHL tracking number , which does not exist.

Only suckers would buy anything from this company.

If they're on ebay, i bet they would have 1 star feed back.

here are some examples of your awesomeness:
+ cant even make fcking connectors
+ test pumps complete dry, you must have thought pumps are like fans huh?
+ ignore RMA request, only respond when you got disputes from paypal, then lie about replacement shipments.

I dont know if you're stupid or you're just fcking trolling us.

Seriously  ::)


EDIT: syecooling = syscooling? WTF?

Does not matter if it is this kit or the previous one if you guys suck at supporting customers. I have avoided ordering a C1 due to all the complaints about your pumps..

Well,surely there was some problems with our early products and service,we don't have enough experience on foreign bussiness,lead to some unnecessary misunderstanding on communication happened.Now we have settled the problem,no matter on products or service.Your pumps was sent yesterday,and it need some time to update.We just provided you tracking NO after courier took away it.

Well,I have to say this is misunderstanding.Negative feedback we heard by now is about first batch,surely as your examples,about wiring,pumps,and I think the problem happens because of our lack of experience on foreign deal.Also lead to mistakes on our inner communication.But now all those problems are settled,and only a little part of the first batch had problems.We want to be better,to provide good products,and the improving process was really tough.What we are doing right now is just to reverse the attitude of customers about first batch.Any componets failed and we will send you new,usually the postage is higher than components.

Well that is all it takes...just treat customers well and RMA fast! Miners have been f@cked over so many times that we are done with it...so we are quite testy about things.

Not really,all complaints you see is of several very people,and truely there was misunderstanding in our treatment,we have tried to solve those problem without counting cost.You didn't see other process of after-service,and few peole whose watercooling kit worked fine post here.

Your advice is appreciated,and I understand your paints when received bad products,since I am mining everyday,too.

I have no idea about who you are Mr.syecooling,you really puzzled me ;),but I am sure you must have used our products and had bad experience.I like you,you give me the chance to explain all complaints we received.

I don't know if it would make any difference, I bought 4 Batch 2 C1s with cooling kits directly from Bitmain. They have been working well for over a week now.

I had two broken pump  and 2 wired harness

Dear ... ,

As you have issue the dispute on the paypal , asking us to compensate fo‍r you 40$,

Now our second solution is that we could compensate you 30$, then you cancel the
dispute .

Any more question email to me with free .

...------------.................-------------------........................
But you never did  offer for me this 30$  through paypal dispute.

Three kind of wiring harness,either is ok to be added into watercooling kits if you contact us when you order it.

Your kit included two broken fans in my last order and basically syscooling told me me contact Bitmain, which I did and he's refusing to send replacement fans UNLESS I actually order another miner from him. He's using the excuse of cost and how long it takes to get to the US. Strange. My C1's made it to the US in 4 days, now he says two cooling fans will take two weeks. This was a BRAND NEW syscooling OUT OF THE BOX, broken fans and neither syscooling or Bitmain wanted to honor their own hardware only unless I purchased another miner. HORRIBLE customer service. I'll never order anything from Bitmain or syscooling again, and I hope other users realize this. If you don't want to run a proper business and support your customer's then get out of the business.

[/quote]Dear sir,first I am sorry about your broken fans,I know your anger,please calm dowm.Second I'd like to say that the fans were broken because of shipping process,not for quality problems,I don't think we BITMAIN or Syscooling have duty on it.It is express.Personally I suggest you should check products first before you sign it in your online shopping,whether you buy anything from us anymore, or Amazon,Ebay,etc.Third,I think BITMAIN really want to help you,so he says could send you replacement fans as you order another miner,that is not horrible customer service in my opinion.And one more thing I want to explain to you about shipping time，it is customs declaration.When kits shipped,it is easy to get through,when components shipped alone,it is hard to get through usually.

I am not blaming the customer,dear sir.They are just doing what their work requires,that shouldn't be blamed.But I just want you to know what reason causes the delay problem.
Before you signed,I just suggest you to check whether there is obvious damage on products,like broken fans,its all plastic brackets was broken,and it isn't hard to notice I think.I didn't say you should test the whole cooling system before signed.
Price of products in Amazon is extremely high not only because of its production cost.Our price is low,to be honest,if you are in China we surely will sent you replacement.Whether you or orthers buy kits from us anymore,I must explain all clearly.All negative impression on us by now is caused by misunderstanding.People posted problems here and sent us emails,we replied some emails but didn't reply here,so all you see is issues about our products.

I don't think syscooling deserves such negative attitude from members here. A few have experienced some misunderstanding in communications between the parties; however, a majority of customers have received syscooling kits and they are working as designed. I think it's not reasonable to demand syscooling to compensate for the lost mining or to foot the bill for replacement in shipping both ways, especially after starting a dispute process with paypal or the credit issuer.

I think it's despicable to create a similar looking account, I'm looking at you "syecooling", and pretend to be something you are not. I think that's totally out of line.

yes, many users bitching about cables and 20 $ pumps not working (I got few and they are working fine since day 1) and seem to forget that only one year ago there were "legit" asic companies scamming people around for 100 or more bitcoins.

Both the pump and cable issues are concentrated in the very early batches (of which I had both), so it seems a bit unfair to keep heckling them for it.

Protection is enough,otherwise all products would be damaged when your receive.Or you want to be opening the package for over 2 hours?
Checking products simply is possible,shipping company have duty on it.If you buy an Iphone 6 you won't see whether it is bended?You buy jewelry you won't see whether it is stone?I will say nothing if you won't.
Your every word is swearing that our bussiness will stop,if that makes you happier,you could think so.

He must have bad experience with our products,I don't know who he is and whether we discussed about his problem.We should always say sorry about the problem for early products,actually we have been solving it for over a month.I am gratified that a large amount of users like you enjoy mining with our watercooling parts.

I have no idea about that company,since I am a green hand here,but it is great that your watercooling kit works fine. ;)

Since the shipping process is a bit long,to be honest the problems were settled even before foreign customers received kits.Because Chinese users find them much earlier.

So it just boils down to you blaming the shipping company now. All boxes were in perfect condition and were physically checked before I signed them. Here in the US and I doubt in China, the UPS man does not sit around and wait for you to open up a box and check all hardware out. It doesn't matter. I won't be purchasing anymore Bitmaintech products in the future.

I got 2 (TWO OF THREE!!) broken fans on my C1 set... Quality work!

Could you please kindly send email to ysun@ysun.net with picture?

I was ready to order this item, but shipping is more than the price of the item and you add 4% to use Paypal. 

syscooling, why you do not support bitcoins as payments method?

You don't believe in bitcoin future?

heck ... show us pictures of the broken fans

They are broken out of their socket

As I bought the complete set from bitmain, do you still offer RMA or do I have to talk to them?

I installed 2 batch 2 C1. One for a friend and one for me. They are both working perfectly. Please stop the throlling.

Well, so it appears one person got 2 working fine, so all the other complaints are negated, please ignore all the previous complaints and stop the "throlling".

We can judge the problem.If you bought from Bitmain,Bitmain is in charge of RMA.

So glad to hear that,wish you have a good experience ;)

Hi Syscooling,

let me know how much cost five units shipped by DHL to Caracas, Venezuela.

Thanks

Could you please kindly send emails to watercooling@ysun.net?

If we have an issue with the cooling kit do we go to Bitmain or SysCooling? I have a C1 Batch 2 with the cooling kit that Bitmain sells with the C1, everything came fine, got the kit setup followed Dogie's instructions plus the video on SysCooling's site, setup went smooth after I get all the coolant in, all bubbles out and actually let it run like it should (not shutting off and on to fill coolant as it flowed through the kit) after 3 minutes the pump will no longer pump fluid.
I was very careful with setting it up and adding coolant because of Dogie's instructions and I didn't want to kill the pump and like I said it was running fine for those 3 minutes after I was done with the setup.
I even tried a couple different ways of powering the pump, tried using the connection on the inside of the miner like the fan is hooked up. Of course the power adapter kit that came with it (which is how I set it up), then also tried a 4 pin molex adapter that I had for some fans hooked up directly to the PSU.
This is not my first water cooling system that I setup so I have some experience with it.

Also when I got the kit the 3 fans on the radiator did not work at all, I take that back 1 worked, but I ended up replacing those with better fans I had lying around, I am not really worried about the fans it's the pump, I have the C1 sitting on my rack doing nothing because I can't / won't run it without the cooling kit working.

I am seeing that others have received broken fans as well, I will take pictures and upload them tonight when I get home from work tonight, they basically fall apart, the blades and assembly just separate I had 2 like that and those were the 2 that wouldn't run when I plugged them in. I will upload pictures later so you can see, not sure if that's what other people experienced but at least you'll have one visual of the fans. I will even ship them to you if wanted so you can inspect them, then maybe batch 3 or 4 everything will be better.

Any help is greatly appreciated.

Thanks
Ryan

Would you like to try  wash  the impeller of pump with liquid as the following link
vedio :

https://www.youtube.com/watch?v=n_y9CL9Wh40‍‍

I don't mind giving it a try. Anything to get this thing mining. I get home in 8 hours or so, I will try it then and let you know how it goes.

Not sure if this is the way the others fans came but here are 2 out of 3 fans that I received 1 was in perfect shape and worked these 2 well obviously not. I am going to test the pump like you asked shortly and will report back but I wanted to get you guys some pics of the fans.

Would you mind taking a few pictures about the bad pump?

OK I see the fans.

I'm about to drain the coolant then take it apart as shown in the video. I'll take pictures of everything for you give me a little bit and you'll have them.

Thanks

@syscooling

Thank you for the tracking number

;)

When you take apart if you see any coolant on circuit board please take a picture.If available you'd better take a short video that the pump doesn't run when powered on that we can see.

I purchased 7 C1s from Bitmain with Syscooling kit in tow.. out of all 7 kits the only problem was two fans were broken on the thin plastic connectors between the fan itself and the fan frame. Everything has been running for 5 weeks without issue, all works perfect, pumps, fans, etc...

I simply went to Amazon and purchased two replacement fans and continued mining. Easy replacement and not expensive at all.

I am impressed at this point with Syscooling. It is quite nice to have such quiet miners.. thanks to Bitmain/Syscooling. :)

In your next order,please email us or Bitmain with pictures of broken fans,we will send you two more fans as replacement.

Would you mind taking one more picture with all 3 broken fans in?

So I took the pump apart, it worked when it was just the motor, put it all back together, it would work again while filing with coolant then quit just like before. Attached is a link to videos and pics, also another pic of all 3 fans.

It seems that the pump is working fine.May it be that the pump is too quiet that you even didn't notice it is working? ;)You could turn it upside down to let air get into motor and see whether it is working.Do you use Skype?My Skype ID is syscooling_rma,you could contact me via that. Or send email to ysun@ysun.net,so that I could help you as soon as possible. :)

Is there any reviews of this kit?  Videos on Youtube? I'm curious how the back looks (yet, no photos of it anywhere), are there screw holes to add fans to the back? 

Yes there are screw holes,you could add fans.

Any USA resellers for this?  I would like to order one but the shipping price from manufacturer is way way too high.

Sorry to say that there is not any resellers. :)

Received the kit today.  You stated there are holes to add fans to the back.  I'm confused, I don't see any.  Please show a picture of what holes you're are referring to, to add fans to the back.  Perhaps you forgot a piece in the set I received and need to send me the additional bracket that's missing?

Looks like they are calling the back what you see as the front :)

How can you add fans to the front then?  No holes available to add fans on top of fans already on it then.

hi!

do you have any involvement, cooperation in the new s6?

all i'm really asking is if it's  gonna be compatibility for s6 from your water-blocks!

thx!

You stated there were holes to add additional fans to the back, but haven't cleared up that statement yet.

That is a condenser for a car A/C system. you can get them on ebay for new as little as 25 dollars.

You can use 3m double sided tape, which is REALLY adhesive. That would hold a fan on there indefinitely. I wish you the best of luck with that kit. You need a lot of room, tons of fans running on that radiator. Let us know how you work out.

Do not buy this kit

hi. I would like to know the speed of each fan for this cooling kit??

Because i was wondering, if want to extract all the air that is expelled from the radiator i should know all the volume of air i must remove from the room where the mining machines are working.


Thanks a lot

Sadly I don't think you will get a response on forum syscoolings account: Last Active:    March 21, 2015, 09:35:43 AM

You stand a better chance emailing them at this point I think.

And what are your thoughts on mantaining the room temperature right? should i install 12000 btu per hour of air cond for each radiator set that is about 3500 w max, (3500 watts = 11950 btu per hour).

Or should extract the same amount of heated air from the room, measuring how volume of air this radiator set works with???

Thanks My friend
