DDC TOP poll: what TOP do you use with your Blue impeller DDC

Once again, interesting results so far.

I'm sure you can use the market share number here and extrapolate to your poll the failure rate. It will be an interesting result to see.

Please go back to my topic and re-read the first post and please point out to me where I singled out XSPC for market share. The question for the poll was as generic as I could make it and had zero bias for any particular top. My topic (from the start) is an attempt to find some commonality to why DDC's are dying, not to find a failure rate. The info collected here is just raw number of tops in use broken down by manufacturer, that's useless to me as it doesn't tell me what else is in the loop. There may be 10 other loops set up exactly the same as 3 loops that had the pump die but I won't know that if that info isn't collected. Is that really so hard to understand?

When I said "question" I meant the question users were doing regarding your topic result.
The main discussion at the forums was that XSPC tops were prone to failure due to some bad design.
People argued that it happened more with XSPC tops due to the market share.

Sorry again if I don't understand your topic but I do understand mine: We will have some pretty raw estimates on market share (don't care about fail or no fail) and it is very useful number to compare to a poll with all DDC failures. Statistically it won't matter if a particular pump was under stress and failed because of it. This could happen with any brand.

we have 102 entries untill now.

The results for market share are:

XSPC 51%
EK 31%
Petra's 9%
other 6%
Koolance 2%
Bitspower 1%

EK Dual top V2 on dual Liang DDC 3.25

OK, let's try this.

Lets say 10 ppl build their systems at the same time with near identical loops, XSPC res top > MCP355 > PA120.3 > EK Supreme HF > res, the only thing different is the fittings (which aren't going to have a great impact on flow rate) so their flow rates are all within a few mL of each other. Now lets say that 3 weeks in, 3 of those ppl have their pumps die but the others all still go strong for their rated lifespan. I want to find out why those 3 died. It couldn't be the flow rate (which is my leading suspect ATM) within the loop because 7 other pumps didn't die, so it has to be something else causing the deaths. It could be a bad batch of MOSFETs, or the shape of the volute in the top is off, or it could be that the PSU was providing to much power...the variables are actually mind staggering. :nuts:

I need complete loop data for both my poll and yours to be able to make any use of the numbers in the poll itself, the poll is nothing more than a quick tally counter and is useless on it's own.

OK, I honestly disagree.
I don't think you will be able to discover the missing link on the dead laings case with the results on your thread, but I'm supporting your idea.

BTW, the quick tally counter already gave us a rough estimate on market share. :rolleyes:
