Just like the thread says..i have two mounted together with the acrylic block provided by performance-pcs...They are getting really warm..almost to the point where I think i shuold throw a 80m fan under them or something. Each one has a 4pin molex but only two pins are in it..The powersupply couldn't be like..pushing too much through those two pins to cause them to get hot..could it?

12v DDC's getting HOT!
- Thread starter tbo
- Start date
Actually my pump (MCP350) was running hot (too hot to touch) when I started it up for the first time and within 5min it burned out. I was sure fluid was going through it, but there was also a lot of debris which was probably impeding the propeller. I opened it up and some of the PCB melted. The point of the story is if the pump gets too hot something could be wrong.
The majority of the DDC's from Laing's bad run would fail exactly in this manner. But the temperature of the pump itself is irrelevant if past this point of initial use. My DDC is warm, my iwaki is warm, anything that generates motion will be warm.
Two DDC-2's in series is the best pump setup out there for most mainstream users. You'll get incredible head pressure (important and don't let those misinformed few convince you otherwise) and redundancy to boot in the case of a failed pump. Is the 240 a radiator? If so, yes it would be able to push through that with ease. If your radiators are exactly the same, I'd suggest putting them in parallel. Pumps in series, like radiators in parallel. You'll have a great setup!
I've got a DD tdx for my 6600 and i've got the BFG 8800gtxWCE (dd block).
I just got the rig going very recently and heat has been a major issue..and it boils down to the fact that I only have a 240 rad between the c2d and 8800..and i've been idling at like 50c and i can't even run orthos without fear of a it shutting itself down.
The plan is to either break off the 2xddc's and have 2 seperate loops or..if possible (which it may be as you guys are saying) just throw another 240 into the loop. Your saying I shuold have the rad's back to back?
Two separate loops would give you better temps on both components but the extra complexity and cost can only be determined by your own needs/constraints. If you plan on keeping everything in 1 loop, then put the pumps in series and the radiators in parallel (with Y-branches). Rad placement itself is irrelevant. Just try to use the least amount of tubing when routing things.

There you go, from my understanding your CPU runs very hot and your pumps run very hot i think you have something stuck in your loop there fore your water is not moving 
creating high temps on your chip and stress on your pumps.
OR there is a kinck in your loop/tubing.

I'm located in the south eastern corner of wisconsin. idling at 50c rihgt now and its probably 70-75 degress in my room.
I think the plan now is to get the attatchment to convert my two pumps into two seperate pumps like this
And pick up another 240 rad..The question now is where do i mount it. Heres a mocked up picture of my case (camera isn't workign at the moment) with arrows showing my airflow..One person said my airflow is all wrong.that I should have it bring in air from the outside of the case...What do you think?
The red is my current 240 and the light blue are my fans..And the pink is where my pump is.
The Green represents the idea of where I'd like to moutn another 240..and have it a few inches off the back of the case. Question is which side of the rad would I have the fans at and which way would i hvae them blow?? Or would it be better to have one on the top of the case...On top seems like a cleaner look to me, but if i had it cut into the case and blowing straight down into the case the airflow would be restricted by my powersupply and all my hosing and power cables...Or would it matter since the air is already past the radiator?
EDIT: I just threw my stock fan on and its idling at 37c and at 55-57c at full load..YAARGH! Oh well..atleast now it'll be happy while she waits for a new radiator.. I appreciate all the help guys! I've learned quite a bit in the past like..day.

Your temps are definitely too hot for your ambient temperatures. You might have a bad mount. Are you mounting and remounting your CPU waterblock to see if there is a delta in idle temps?

That's a good step forward towards building a high performance WC loop.

Your temps are a direct result from your misconfigured setup. You need to reverse the fan direction. You're pulling hot air from the motherboard to cool your radiator. Reverse the fans so the pull fresh air in from the front of your tower. Cut holes if you have to and cover with mesh. You can use a radbox to mount your 2nd 240 radiator. However, I'd consider cutting out the top and placing the radiator against the top with half of it in the 5 1/4 bay. Either that or place it at the bottom of your case with fans pulling air in (you'll have to cut out the base of your case).
my same pump is acting up. on off on off pump has mind of it's own

RMA it. Never had Laing deny an RMA before either through Swiftech or Petra's.
Utterly fantastic world renowned Laing reliability.
I gather these kinds of problems aren't related to this only being a certain very old run of DDC pumps? Seems like a lot of DDC issues here in the [H] again. I gather that an RPM sensing wire is a fairly late model pump?
BTW, is that the radiator on the back of the case? Do you have any fans attached to it?

Hmm you know, considering most of the WC'in world uses Laing pumps, you'll see more reports of failures.
Going back to your fatally flawed analogy regarding cars (where Erasmus basically "owned" you). Toyota owners can report a bunch of stuff about their cars. That's probably because they sell more than Saabs, who would report less due to the fact that way less Saabs are sold than Toyotas. Not to mention, nothing still hides the fact that Eheim's can't push worth shit. I'll keep both my Eheim's in water tank where my fish reside.
But seriously. Someone at AC needs to put TN on your payroll. She probably does more to promote your products with relentless "Damn the torpedoes, full speed ahead" tenacity than your entire advertising division.
If you're going to work this hard TN, you better be getting paid. If not, I hear the republicans could use some PR help with the shit they're going through right now and could use some more spin doctors.

HAHA.
careful.
If that is all you got out of that post you are reaching for straws. Erasmus354 and I have been having this same argument for years and it goes absolutely zip on both our parts.
Lots of people all over the world use Aquastream and HPPS pumps as well as standard Eheims for water cooling. Don't assume that just because people in the USA use a lot of Laing pumps that the whole world uses lots of them as well. I'm sure it is used a lot as they are cheap pumps, but not semi-exclusively as you seem to imply.
When is the last time you heard about a failed run of Eheim pumps? Just for grins I did a Google search for "failed Eheim pumps." Then I did a Google search for "failed DDC pumps." Guess which one had none and which one had lots over several different production runs? As somebody else commented recently just because the Pinto was massively sold didn't change the fact that they were dangerous.

Well if that ain't the pot calling the kettle black.
If you can't brow beat them then flame them, huh? At this rate you will never make it to being a [H]ardGawd. Maybe they allow this kind of bs where you came from over at xtremesystems, but over here personal attacks are frowned upon.

LOL. TN, I'll include a "/sarcasm" next time. It was a humorous comment. I'm surprised you too it so harshly with all the barbs we trade back and forth.
Forgive me darling.
