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

[Waterlogged]

Do you think the results may be different in daily use ? I'm looking for quiet tops. Sorry for the off topic.

Honestly, I've never noticed any kind of difference myself...once the loop is bled, I couldn't tell you what top is on the pump.

[skinnee]

Maybe I am more hard of hearing than I thought (deaf as a post), but once my test loop is bled I can't discern any difference in noise from one top to another on the same pump.

[Church]

Depends on methodics used in testing i guess. After all, part of pump noise is made by air bubbles hitting impeller in not completely bled loop, so depending on if in testing loop has been fully bled or not (sometimes takes long time in some LC setups), noise might differ in tests/daily use.

[skinnee]

Yeah, but I am talking about the bench loops too... where I am not changing tops every hour or so.

[bundymania]

So you often visit discos / parties with loud music, when you were younger ?

[skinnee]

headphones being way too loud and working in a mechanical shop next to my old man with no ear protection as a kid. But I can certainly hear a loop being bled and know when air is present in the pump head.

If this is pointed at me, no. I spent much of my "youth" working second shift (3:30 PM to midnight), so I missed out on the party scene. I also dislike headphones because I spent 12 years of my life wearing hearing protectors (rated @ 29dB) at the machine shops I worked at for 8 hrs a day. While not what it probably should be for someone my age (compared to someone that's been living in a low noise environment), my hearing is rather good. I had to get rid of a Shuttle SB61G2R 20th Anniversary Special Edition XPC due to a nasty squeal from a coil on the MoBo and I hear crap a lot of other ppl can't seem to hear.

I was part of punkrock / rock´n´roll bands for 2 decades and hear nothing over 10 KHz (and 2-10 KHz only bad) - but I do still hear the differences of my Laing-tops

poor Skinnee Probably you should better use your laboratory equipment to check the differences

[skinnee]

I'm still waiting for the Creative Labs ear upgrades.

But in all seriousness, I cannot hear a difference in pump tops. Pumps yes, pump tops, no.

My laboratory (btw verified by others)

To my point, you're still bleeding the loop which is evident by the air bubble stream in the tubing.

caught! But no change without bubbles.

3 EK V2's on 3.2's in series, no trouble at all. And I used to run one of them as a 3.1 on a XSPC restop, also trouble-free.

[rge]

Does seem a little weird with XSPC tops. Roughly 1 in 4 (25%) with XSPC tops posted dead pumps vs only ~1 in 19 (~5%) with EK tops. Not scientific, but I wont be switching to XSPC tops anytime soon either. (added pumps voted from both threads, + those in posts unaccounted for (ie justin had 8 xspc tops so added 7 for him since he could only vote for 1 xspc), and subtracted duplicates from 2 threads).

[eclypse]

No one brave enough to use those XSPC Tripple DDC tops?? I'm gona be putting in 2 with 6 pumps soon. Hopefully everything will be good as i'll be using the older 350/3.1 pumps.

[Waterlogged]

While I originally dismissed needing this side of the info, I started seeing the need for this poll just before this was started and was going to do it but leo beat me to it. I'm just really disappointed that it's nothing more than a generic "what top do you use poll" and fails to go any further than that as far as data collection goes making it rather useless for correlation purposes. For it to be useful, the exact same info should be collected here as in my poll. I may have to do this poll myself if this one can't be fixed.

BringerOdeath and fatcat did, didn't have much luck with them either...though, fatcat was using MCP355's and BOd was using 3.25's.

Well, the one thing it does do is show that XSPC tops are in wide use, but it doesn't corner the market the way some people have claimed. So far it looks like the XSPC tops are about 50% of the tops out there. It seemed many people believed it would be closer to 80%

I can't change it, but I think you can still use the data.
You did not ask on your poll what kind of XSPC top, so you can add the results from the res/top to the regular top.

Sorry to make the wrong options.

I'm confident you can use the data, right now we can tell that XSPC has almost 50% of the tops market (not scientific result).

Leo, I ask the ppl responding to my poll that they mention exactly which version of the top they selected in the poll when they post the info pertaining to the rest of their loop. The reason this is useless for my purposes is the fact that all that's being collected is the top used, I also need the rest of the stuff in the loop to help determine what the flow rate (and by extension, current draw) is in the loop. You would know this if you read my topic. Any votes for tops that don't have the accompanying loop info in a post will be tossed if it is not provided by the end of my poll.

[MpG]

Suppose I should add that my setup (DDC 3.2 x3,EK V2 tops) was pushing through either a CPU-only loop (various waterblocks), 3 PA120.3's, and later on had a DD Tieton block (low restriction) added in.

I also had a flow meter installed briefly during the CPU-only times, and with a KL-350, flow was about 2.2-2.3gpm, and was presumably somewhat higher with the GTZ and HK3.0 installed.

whats the point u are in RD territory at that point in price

[DeeDs]

2 x DDC3.2 w/ XSPC Res Top for 2 years.
1 Pump died due to bottom of res top leaking between base and top chamber where glued together.
Spent ages trying to find leaks on all my fittings didnt think res would fail .

I read your topic.
The main question were what market share XSPC has, I think it is pretty clear. All critics on your poll was not knowing the market share you cannot say XSPC has a higher failure rate or it is simply the best selling and than has more people with dead pumps.

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.

[stangracin3]

I remember there was a point where the only top that was reccomended was the XPSC. this was before the ek revision 2 was released.

its no wonder that more are failing.
plus you have to remember that the xpsc top is probably a year older than the ek, if not more.
