More Petra'sTech DDC Pump Testing (curves, power, new pumps/tops, etc.)

Yeah Alex, that was kind of where I was heading with this. At least if we could predict a loop's flow with even rough accuracy, it would make part selection easier. A tool, or spreadsheet could be made for this. (It would also help with multi-loop design)

I don't expect to see the manufacturers putting this out anytime soon. I would think this type of info is a well kept secret, if they even do testing like that. (Except for you of course, you published your top data for all to see.. )

(Edit - Well after looking around, I find that some of this info is available. Maybe I'll try scooping some up and see if a spreadsheet tool is possible. I would be curious if the tool could get even close to my test results. As Alex suggested, I'll try an intersecting curve type approach. It will be one of those get-around-to-it things. Right now my issue is trying to cram all the stuff into an Antec 900 case, DOH! May have to get a new case....)

Note that this information, by itself, would not constitute a good part over a bad one. For example, if I'm not mistaken, the Storm is a more restrictive part, but a very effective cooler, for it's particular application.

The proposed tool will not accurately predict what temperature you'd get out of the loop, but at least you would know the flow. There are probably too many other variables at play for accurate temperature prediction, but I think good, calculated flow design would help max out the loop's potential.

Perhaps the next step might be to have a tool that can calculate the heat dump of a given radiator, with a given flow, for various temperature deltas. That would put us one step closer to being able to predict temps, or at least the ideal cooling capacity of the proposed loop. (So many radiators, and so many fans!! Just think of the permutations to test!! )

One problem I see is the variance block mounting has. You can get the temps to move all over the place just by paste and mounting attempts. I suppose that may be overcome as time goes on.

As it stands, my experience was to pick my parts, then just measure the whole mess. If I get a good number, well OK. If I don't, I'm forced to troubleshoot to the offending part. Of course, what is a good number? That's what I'm trying to get more info on. I do not have years of experience working with this particular type of system.

For the purpose of getting my quad taken care of, I'll call 2 GPM good and see how it does in the machine....

I have to admit, this was a fun test to do. I don't have a pressure measurement setup, so I'm limited to only max flow measurement.
