Bought everything as a kit. I called the Colorado support facility and the guy said all he can do is have me ship my entire system over to them and they will find out what is wrong with it and fix, no matter what it is. So I lose a couple weeks mining, big deal, and have to pay to ship that and my cooling system to Colorado. Hey, at least their willing to help. What's BitmainWarranty going to do? They would have probably told me to do the same thing. Only thing that bothers me is having to pay shipping for an in warranty product. I'll remember that next time when wave of new hardware comes a along. Other companies provide you shipping labels.

WHAT IS OUR RADIATOR MADE OUT OF? THE ONE THAT CAME WITH THE KIT? ALUMINUM OR COPPER?

[BitmainWarranty is the Denver, Colorado centre, calling in is just a quicker way to contact them]. I think it is the best solution to return it now, as whatever stuff is growing in that loop will be all up inside those blocks as well. I'm here to see if we can help people remotely without having to ship stuff across a country / continent as then everyone loses out.

They usually do provide labels but I guess its a bit of a confusing situation for them - let me know after its all completed if you're still out of pocket and I'll try and get it sorted.

My guess is copper. They have always been very careful to say to use coolant not water. That and it looks a copper "PD360" on their site we got: http://www.syscooling.com/products/Radiators/54.html . The two aluminum radiator's they show selling are much smaller then the one with kit.

I could be wrong if they used a specialty one for miners, but I'm highly guessing its their standard.

Yes, you have to assume its copper or there are copper components. In several points in the listings (all changed by now) there has been a mention of copper on both the radiator and the fittings [internal coating]. You can see within the chamber of the radiator that there is definitely some form of dark orange coating, which may be brass or copper. So tldr, be safe and assume there is copper and aluminium within the same loop.

My system temps have slowly been crreeping up too, when the unit was new the temp was all 34c +-1 C now all units are 35-38C sometimes 33-40C seems like there a BIG temp variation with liquid cooling,
Especially is they are all sharing the same Liquid loop.

And its ONLY been getting COLDER HERE (-10c to -16 the last few morning and just over 0c during the day) - My heat in the house where the miner is kept is off...

Read this too: http://www.overclockers.com/pc-water-coolant-chemistry-part-ii/

Try to blow out any dust that's caught in your radiator. Power off your miner, and take a strong blow through the radiator, I did mine both ways and temps went back down to normal. Since it is winter here, all the dust in the house gets into those radiators pretty easily. Same the the miner. I have a large 5HP shop vac that has the air blow output connection. So I use that instead of wasting money on canned air.

I read that article also. My next coolant I'm buying will be one that works with all metals and is all premixed, since apparently no one can even confirm what the radiator is. I thought Dogie, the paid rep here would know, but he just speculated.

And over a dozen liquid cooling websites I've been on, they all say distilled water with silver shards in the tubes have always been a fantastic coolant method. I said that before but Dogie said distilled water isn't really a good idea, but his recommendation in the first post was a bottle of ironside coolant which is distilled water. I can never believe or trust a paid rep. Of course they're biased.
