-what pump are you using
I used the same kit I've done with my PC water cooling, since I have more experience with it:
http://amzn.to/1PrlNZDhttp://amzn.to/1gM7umgThe flow rate is pretty much identical to the one it ships with (which is what I'm including) - but if you'd prefer to have one of these pumps, I will include it w/ it's matching reservoir for $100. I'm not super motivated to sell it as I plan to use it on my next build.
-only 2 days of testing? i see your post in Tupsu's thread on 21 september
Actually, I built it a couple days before that, so it's been running for about a week - even though I bought the kit probably 6 months ago. I clean purged all the components for 8 hours and ran it 24 hours unpower first to check for leaks and other issues, everything is solid. I also use hose clamps for everything, which are a bit of a pain to take apart, but almost eliminate the most common leaking issues.
Lately I've been focused on the air cooling stuff, so I needed to get it to a stopping point before I could explore water cooling:
https://bitcointalk.org/index.php?topic=1184272https://bitcointalk.org/index.php?topic=1086882So now next on my list of things to do is experiment with building some custom water blocks... Before starting that though I wanted to see how the existing ones worked, so I would have an opinion one way or another about what I like and didn't like about their design, etc. One thing in particular I would like to do is incorporate water cooling for the PSU as part of the loop also, as that is also another source of heat (at least the IBM 2880W ones are).
-do you sell only the unit, without the rest?
I wouldn't - there's not a huge point, it would just be adding a bunch of additional work in me taking it apart, and then someone else going through the process again. Plus building the cables is a nightmare - really the biggest failing of the design IMO, and Bitmain won't sell the extended cables from the S5+ individually.
One other advantage you get with me building it is that I'm detail oriented and pretty meticulous when it comes to these sorts of things - if you check out any of the things I've done before, you'll probably agree - so you have good confidence that it's been built right.
-temp of water entering the unit & temp of water out of the unit
No idea what the inlet water temp out is - and to be honest, I don't think there is a huge amount of value to knowing it. With any of these systems, it's just what the loop temperature is once it's at steady state. If you read my Tipsu post, then you know the house temps were - basically at 26c room temp the water loop was at a no load temp of 29.5c, and at full load it was at 33.8c (there might be inaccuracies in the water temp sensor, so the delta is more accurate that the value). The S5's temps were from 52c to 60c, no particular rhyme or reason as to which blades and the temps, but it was pretty consistent - I imagine the accuracy of their temp sensors isn't that good. In the same setting I have one S5 fully stock and it was running about 58c - all running the latest firmware.
In my garage it's about 35c ambient, the loop no load runs about 36c, and at full load it runs about 45c. I will say the placement in my garage is non-optimal, I really just put it in there to see how it performed in a different (hotter) environment - it's right by the InnoSilicon A2's (you can see them in the background), and they radiate a fair bit of heat. The S5 temps are from 61c to 68c - in the same setting I have another stock S5 with the little factory heatsinks on it, and it's running 70c, but to be fair I think it runs a little hot for whatever reason.
Please post the screens with the asics status! interested in temps
Your wish is my command!
Nothing too exciting here - all my machines are off 3 hours of the day because of the TOU power plan I use at my house, so I automatically back them off to 100hz for 15 mins prior to shutdown to avoid thermal shock. When running in the house I didn't get any hardware errors, but 0.0001% is on par with what the majority of the other S5's I have in that environment do.
For thermal compound I used this:
http://amzn.to/1Lvy3cjwhich is my favorite, works much better than any of the other thermal paste I've used - it's particularly necessary with the waterblocks, as they aren't nearly as smooth as the normal heatsinks.
