Best bang-for-the-buck reservoir - Page 2

post #11 of 20
Yes, a tube would reduce splashing. The primochill comes with the tube. I didn't know that and ordered of when i ordered my first ctr reservoir. The ek includes one as well.

My understanding is that ek does not sell the pump top for the reservoir separately (I haven't been able to find the pump top separately). So you would need to buy the pump enabled reservoir, with the additional bottom to use separately. You could also get a separate pump and just run a tube, out connect with a fitting, but personally I prefer the pump mounted to the reservoir for space saving.

on the standalone bottom, either port can be in/out. On pump enabled reservoirs, typically one port is out, and all others are in. Some will have 2 out ports for options.

This is also a good value. The pump has less power than a standard dd, but will run about 2gpm without restriction, and has good head for a small low restriction loop.

I am currently trying to look for as inexpensive small d5 reservoir for a gpu loop I am considering... I have a spare d5 that I could use, just need a cheap reservoir to go with it.

That's good to know. The EK I've linked doesn't have one. It only includes these:

 

Enclosed:
- EK-Multioption RES X3
- Pair of EK reservoir holders with mounting screws
- 2 × G1/4 extenders
- 4 × G1/4 Plugs
- 1 × 6mm Allen key for plugs
- 1 × 2,5mm allen key for reservoir holders
- 1 × polyether anti-cyclon foam

 

And then you still have to buy a $17.99 multiport top if you want to go that path.

 

Yeah, I wouldn't want to run a tube between the reservoir and the pump and prefer a reservoir/pump combo as well. It's essentially what I'm doing with the H220X in my system but would want to refrain from doing it in the future.

 

If I go with the D5 enabled SFF Primochill reservoir, should I still buy an "additional bottom" for me to use it as a standalone?

 

And why is there no "DDC enabled" reservoir?

Why can't a normal top (only with one port) be used as the return port alone? I mean why does it need other ports to work correctly? Is it because you won't be able to get air out (bleed) without an open port while filling?

And if you use a top port (in a multitop) as a return port, you would need those internal res tubes to avoid "splashing" of water when it returns to the reservoir, correct? Let me know if I understand things correctly.

What do you mean by "your next case may be different"?

Yes that is exactly right. A single port top is designed as a fill port only. Using it as a return port means you can't add coolant and let air out.

The drop tubes for top return ports create an air lock to stop coolant flooding the res and letting air move upstream from the res.

So what happens if you put excessive coolant while filling a multiport top that has a drop tube installed in it? How does it exactly prevent it from flooding the res?

After reading this Primochill CTR res review, I'm kinda getting mixed feeling about that res :(

It obviously cannot prevent you from pouring in more than the res can hold but, without the drop tube when the pump stops any coolant above the res, like in a top mounted rad for example, can drain down into the res and over flow if a port is open. At the same time any air in the res can move upwards into the rad. The drop tube air lock stops the res over flowing even with an open port and prevents air moving up to the top rad when the pump stops.

Without a tube the res level will rise and fall with the pump. With it, it stays perfectly level.

Every so often you see a thread in here from someone building a new loop that omitted the tube. They have a res that rises and falls with the pump making it very hard to get the whole loop filled and makes a gurgling racket.

I've had good experiences with them, but there are a few small tolerance issues. I recommend them based on my experience with it, and the size limitations you have. Overall, I feel that it is a good product, but could use a little more refinement.

I have included alternate options, which I think the ek model is a good one. If you know that you will be going with a pump model, I would honestly just wait until you replace the pump, and go with a unit that can install a pump or comes with one.

If the loop that you are running isnt very restrictive, then the XSPC D5 or EK-XRES 100 SPC-60 MX which are reasonably priced and offer a good flow rate for a small loop with 2 high flow blocks and a couple radiators.

Ok, I see what you're saying. I see a lot of videos that has a res doing that rising and falling coolant level during filling/bleeding.

So that drop tube is recommended even when not using a multiport top?

Fair enough. I'll see what I can do then. Thanks.

If the return line enters above the waterline, it should have a tube of sorts so that there is no air gap. If the return line enters the reservoir under the waterline, then such tube is not necessary.

Some reservoirs that have attached pumps will have anti vortex features installed to prevent pulling air into the pump. Usually a plastic piece sticking up from the bottom of the tube in the center.

Right. So which prevents the overflowing of the res when filling, the anticyclone piece or the internal tube piece?

internal tube, basically having the return line underneath the waterline in the reservoir. Even with the tube in, the water will rise in the reservoir a little with the pump off.
