Dallas Digital One Wire DS18B20 probes. These are good to about .2C absolute accuracy in normal water cooling temp ranges and have a nice fine .0625C resolution. Also since they communicate digitally, you can string the power, ground and Vdd wire in series between all the sensors limiting the amount of wires significantly.
I’m looking to log temps for about an hour after stability is reached to average out the ambient fluctuations.
Not only that, but push consistently beats pull in his testing. Even when the difference is less than 0.5*C.
No, his error shouldn't be well below since there are way more variables than just his temp probes.
And yeah, push does consistently beat pull in his testing, but the lower you go on rpm the smaller the gap becomes. And you have to think about the loop in question too instead of just showing numbers from Martin's testing. On a single rad the difference could be 1C, but how about if you have a 120.3 rad, or multiple rads of different sizes. And really, if you can choose between functionality and that 1C lower temps, which will you take? Push is probably optimal temp wise, but it's not all that matters. Can't remember whether push and pull had a noticeable difference in noise or not, I remember reading somewhere that pull is quieter but don't quote me on that one.tl;dr
On low rpm, it doesn't matter whether you push or pull. (I consider "low" to be sub-1000 rpm, 1200 max.)ps. lets not fight about this in fr0st's log.Edited by Blizlake - 7/16/12 at 2:00am
