Also costs a fair chunk more, but yes, its a tank.Quote:

We thought that you might have overdosed on cake! :eek:
Glad to see that you are still with us. :toast:
This thread just got me thinking about where my receipt is for my DDC+ that I bought last May at Microcenter. I can't find that receipt anywhere. Fortunately I just called them and I should be able to go by and get another copy of the original receipt from their database. Not to mention that I need this receipt so that I can write it off on my business taxes.
Cake Overdose is an oxymoron ^^Quote:

"Hello John,
Yes I did receive you DDC pump. The problem is that it has not failed. I have had it running for more than a day, turning on and off and still no problem. I will run it long to see if it will fail, if not I will be sending it back to you, and you will need to contact Laing because there is no way we can put a claim in as defective.
Best regards,
Kathi
Danger Den"
:confused:
Hmm, this gets me thinking. Over the years, I have had strange issues with hard drives. Sometimes, they acted dead, no power, not detected in bios or windows. Now, if I would change the molex connector the drive would then work again. The molex that was in the drive worked, but for some reason the HD just didn't like THAT one. Maybe this is what is happening with these 12v pumps? Just a thought.
Since I have the Alphacool top on it I could see the impeller freeze up until lightly tapped. It would only stall on startup.Quote:

I have a Petra top on my DDC2...sitting on the paper covered foam pad for my D5..the pump gets pretty warm..I have no idea what is too hot..I am thinking of placing 4 rubber mounts to elevate it and then place a few ram sinks on the bottom...since some have suggested these aftermarket tops are overheating and killing these pumps
mebe just the tolerances are a bit too tight making the impeller stall
Interestingly, I also haven't been able to recreate most of the startup issues that people have been having... However, I end up testing the pumps at a range of voltages and varying head pressures and that usually results in me discovering that the pump makes angry knocking/buzzing noises (which it should never do). So, I guess the reason why I've never sent a DDC back to a customer as "working fine" is because I test them thoroughly enough to actually find defects. Swiftech (and likely Danger Den as well) seem to just run a few simple free-flow tests and call it a day (maybe they run it in a simple loop, but I doubt it). Heck, Swiftech doesn't even open the pump up unless you happen to mention something that encourages them to... :rolleyes:Quote:

Yeah, I asked Kathi to run it in a restrictive loop not just Res>Pump.Quote:

edit: do not use above method if you purchased youre pump from Petra :)

About 1yr ago all of a sudden one day my computer screen on boot up is filled with gobbly-gook of big blocks of color. I of course tried an old spare card and it worked fine. So I RMA'd the VC and when I plugged in the replacement, same story. I then replaced the MB. Same story. I finally bought a multimeter and low and behold the 5v line at the molex was only getting about 2v. Turns out a connector on an extension cable that had worked just fine for months was suddenly not making good connection. The old card didn't need to be plugged in which is why it worked.
Long rant I know, but I learned a valuable lesson...
I'm glad after reading about the heat question that I have my pump with top laying on its side on foam so bottom faces sideways and gets airflow.
Yes I used a DVM and it was dead on 12vdc. My D5 is plugged into the same tap and it does, and has always done great. :)Quote:

Update:
When I got home tonight a package was waiting for me from Danger Den. I looked at it wondering if DD had sent my locking-up pump back because they couldn't duplicate the problem or did they step up to the plate and send me a new pump to replace mine?
Well as has been my experience dealing with DD they are a stand-up company and provide excellent customer support. I have dealt with Kathi on several occasions and she has always been very pleasant. So I opened the box and found a BRAND NEW 01/07 manufacture DDC-2TPMP sitting in the box!
My hat goes off to them for showing that they are willing to back their products and must have gone the extra distance to test my pump under a restriction to simulate real world conditions until it failed. :toast: :clap: :clap:
Blue or Black impeller?
Orange.
Wow, that's really good service. A brand new pump. AFAIK all DDC-2s have orange impellers but I could be wrong.
