I have the C1

I meant what were the PSUs

Dogie,

Shitty PSU is shitty unfortunately, wait on your big one.

Do you have a source for the quick release fittings?  Any idea how much the flow rate is restricted through those (if at all)?

Source? Any watercooling shop online. You'll probably find barb fittings easier than compression fittings, just need an 8mm ID. Flow is restricted slightly but it shouldn't be meaningful in our application.

Is there any way to fake the MAC address on a C1?

Hey, I have a few questions.

I'd rather not import coolant, would it just be aluminum safe coolant?

[NotFuzzyWarm]

Where do you  get the coolant? I have automotive anti-freeze coolant, is that doable? How much coolant do you need?

An excellent source for everything dealing with liquid cooling is Koolance http://koolance.com/ They have coolant, tubing, much better pumps and reservoirs, and those nifty 'dripless' quick connect Doggie shows.

Personally, I will be using 3/8" (8mm) ID tubing vs the 1/4" (6mm) ID because I will be using a longer run between the radiator and miner. Like 2 meters each way.

Is not just a matter of aluminum safe. Automotive coolants are designed for, well, cars/trucks and the operating conditions their engines place on the coolant - and what the engines require from the coolant. In short, additives (generally silicates) are added which form a film on the cooling passages. Great for protecting an engine with large surfaces and cooling passages. Terrible for precision cooling needs.

Check koolance.com for CPU grade coolants or just search for 'CPU liquid cooling'. You'll find lots of suppliers.

Truth be told, the biggest thing CPU coolants provide aside from colors is algicides/antimicrobials to cut down on things wanting to grow in the nice warm coolant. If you keep an eye on it from time to time using either DI or distilled water is just fine assuming there is no copper or brass in the system.

Doesn't KL have an annoying minimum order value? Also the stock tubing is 8mm ID anyway. You get ~3m in the pack.

Thanks!  even if I don't buy there, I'll know what to buy.  Sweet guide btw, will use it later once I get them.

No problem

An excellent source for everything dealing with liquid cooling is Koolance http://koolance.com/ They have coolant, tubing, much better pumps and reservoirs, and those nifty 'dripless' quick connect Dogie shows.

dunna know about minimum order. I always seem to have no problem spending a tidy sum there... like a heap of BSP fittings for the 3/8 tubing, a flow meter, tubing, QC's.....

Few other questions if I may...  

Is the cooling kit stated in OP a step above from what Bitmain offers?

I keep reading horror stories of epic proportions, about those SysCooling pumps failing left right and center.

Definitely something I want to avoid, being the low-quality hatin' bastard that I am.

There's a limit though...

I priced a custom kit and went up to near U$300... not really feasible on a per unit basis.

If I could get away with buying the cheaper kit, which is economical and then buying a more expensive pump, I'm still a step ahead.

However, I need to get a reasonable expectation of the quality of the rad/fan, fittings and brackets of said "upgraded cooling kit"...

Obviously I don't want to spend time buying and replacing pumps and/or rads; so, advice is greatly appreciated.

Plus, when BitmainTech says 3.0M Head Pressure and 450L/h flow, how far above that can I go?

Surely there's an overkill at some point, I'd like to know what the OK point is  

Edit: Is it ok to use a pair of 650w PSU's?  I guess one could power each card independently... however, I'm not 100% on that.

It is the syscooling / Bitmain kit. You can go as far above it as you want, but you'll just be wasting electricity and costing more with an expensive pump. Pair of PSUs is fine, just don't plug two into one PCB.

Not easily, unfortunately.  Are you needing to snake a firewall?

Much Thanks dogie

I was looking at a Swiftec pump kit, to at least, serve as replacement; it's slightly faster but with nearly twice the recommended head pressure.

Plus I read Swiftec makes a much more reliable pump and has better service than SysCooling.

Or I could even use the SysCooling pumps as backups, we'll see what happens if I bite the bullet and invest in a reliable pump.

If worse comes to worse, I can always put on stronger fans but those 28Nm from Bitmain are really cool to begin with.

At least now with your help (and others of course), I know where I'm heading and got a good plan of attack.

PS: I ordered a few bottles of IceDragon coolant... yes, it's shockingly expensive but the makers also claims you never need to replace it under normal use.  Every time I invested in NanoTech products, the purchase exceeded my expectations; we'll see what happens, I'll update once I got a few C1's up and running.  Right now, just re-writing my mining plan for adaptation to water cooling.

If I were you, I'd just buy two C1 cooling kits. For $50 you have an exact replica backup set of watercooling. Those 360mm radiators cost $60 in the US anyway!

LOL - You're absolutely right, great idea

That's a gem of a statement.

I'm still gonna get Swiftec pumps, one at first to try them and compare but I'll overbuy SysCooling kits.

It's true, even $60 is a good bargain for tricore rads in the US.

Plus I can always put the SysCooling pumps for sale on eBay auctions, it might cover a part of the cost of the Swiftec ones 

If they do in fact, outclass them. 

All I see is horror stories right, no one comes on to complain about the good stuff....
