New Koolance *Dual D-5* Bay Reservoir! (RP-450X2)

[Martinm210]

Wow..very nice!

I like the compact dual pump placement..and looks great.

The web picture with green fluid is lit with 4 white LED's on the top and bottom. It's not easy to tell with all the other lights going. There are two more holes for LED's on the sides, which aren't being used in this pic:

Thanks Tim. It is what I figured but thought I would ask anyway. All my LED's are 5mm and not 3mm. Is there any difference in strength or brightness?

[Koolance]

The holes we've drilled will only fit 3mm wide LEDs. Ours are super bright. I'm not sure if your 5mm are more or less. The ones we currently stock are definitely much brighter than earlier-gen 5mm LED's.

A silver faceplate might put me over the edge on deciding to buy this

Tim, is your reservoir safe for Jagermeister?

I just switched my name to Tim (may or may not be the desired Tim you are looking for) and say ....YES....YES it will! Please post pics!

If only I could run seperate loops with this...(as in not a shared res)
awesome

that is a recipe for disaster and a dumb way to run a system, IHMO.

Heh, nevermind - actually reading the first post helps.

[Sadasius]

What's the length of the unit front to back? I have, uh, clearance issues:

I don't think that's going to fit in your :banana::banana::banana:ina! Can't you see it's black and is packing a double pumps?!? If it does fit then I am going to call you the local bicycle!

Where's the Can-Do attitude?

[Sadasius]

Yeah your right....I will cheer you on! GO HALO GO!

Just ordered mine. Can finally take out the cracked T-3 and try to RMA it. And not have to worry about my computer dying from leaks. I can acutually put it fully back together

(I was waiting for the DD res, but I really just needed anything that wasn't gonna leak.)

[NFC]

Beautiful.

And 110 dollars? How is that expensive

I was expecting it to be ALOT more with those comments. It's a solid block of acetal for one, and when you consider the cost of two normal tops and a res its even more attractive.

This might convert me from my DDC worship. =D

[Tyranie909]

I was trying to wait for the new DD 5 bay one... I might have to bite though as i can't wait another month to get this build up and going. Whats the difference between the 450 and 450s pumps? Looks as if at 24v the 450s has more head and gph than the 450 for the same price.

[MagisD]

One has speed control knob the 450, the 450s doesn't. laing pumps are werid the letter is what they don't have.

Btw the 450 has a new revision with tach lead.

For the people saying you can add redundancy by plumbing one of the pump outlets to the other's inlet, look at the diagram, it won't work. ALL you would be doing is pumping back into the reservoir, that's it. Those inlets on the back pipe straight to the reservoir.

You are right, now that I think about it the first pump would just be sending fluid back into the res, so if the second fails then the fluid would just be circulating in the res and would not get pulled through the loop. If the first pump failed then the second pump would still pull fluid through the loop and therefore it would be redundant, so in the case you would have a semi redundant setup.

Any word on when these will be hitting retailers? Specifically in Europe?

No alcohol. You'll shoot your eye out--I mean, crack your acrylic.

P.S. Wanted: strike-through tags

Shipments are going out this week, so probably look for stock in Europe by late next week.

[Waterlogged]

This should give some redundancy.



...and for those worried about back flow, I suggest a pair of these.

Tim, If I may suggest a product. Good low restriction, low crack pressure check valves with G1/4" swivel fittings.

[Diverge]

I'm pretty sure if you want to mod the res, you can make it truly redundant without check valves and such. all you'd need to do is run a line on the inside of the res, from either of the ports flowing water in to the res, to the inlet of one of the pumps, then on the back of the pump, run the outlet port to the other res input. Then the pumps are in series, and only one will pull coolant from the res.

That is if internally, you can put a barb on the pump inlet hole.

Unless I've mis-understood you, I don't think that won't give you the effect you want with a shared res feeding the pumps...

EDIT: It looks like I've mi-understood - are you suggesting tubing inside of the resevoir to give a direct feed from one external inlet to one of the pump internal inlets thus bypassing the shared res for one of the pumps? Are they threaded on the inside? is there clearance?

[MagisD]

From the looks of that photo he had res to p1 to p2 inlet then internlly p2 inlet to p2 out connected and finally P2.

So water would go into res then p1 then p2 without mixing in the res again.
