They are easy, fingernail, knife, whatever, to pry the "male part" up, and out, then pry the "female part" up and out. Re-use them forever. I have them on all my fans, got some with a lian-li a long time ago then when some computer website company went under got a whole bunch for cheap.Quote:

The rest of my system uses 3/8" ID tubing, so getting the 1/2" ID tubing required for the stackable meant making a late night run to Home Depot. I really don't like to buy products that don't include *everything* you need to use and/or install the product in the box. Even if you have to bump the price up a buck or two, it would be very nice to have about three inches of 1/2" ID tubing included with the rad.
no instructions? this is included with every radiator: http://www.swiftech.com/products/ins...-stackable.pdfQuote:

This will be my next rad purchase.
To bad both of my ST rads are of the (built in res types).
Yup, positive. I searched the box looking for them. I kinda figured that the .pdf file from your link was supposed to go to the printers and then included with the radiator.Quote:

The "Warning! don't poke holes in your radiator!" sheet was there, just not the installation instructions.
OK, I've been playing around with my new Swiftech rad sandwich for most of the day. Some random thoughts about it...
1. As mentioned, it did not come with the instructions it was supposed to have. It had the "Warning, don't put a hole in your radiator with screws that are too long!" sheet in it. The very same sheet that came with my first MCR320-QP-K which was not stackable. This is strictly a guess, but I'm thinking there was some confusion somewhere at Swiftech, and whoever was supposed to make sure the actual *stackable instructions* from Gabe's link above screwed up; they put the "Warning! Don't punch a hole in your radiator with screws that are too long!" in the box, but failed to put the instruction sheets in the box. I did print up the instructions from Gabe's link. The very first section of the instructions gave the "warning! don't put a hole in your radiator with screws that are too long!" warning, so I kinda think the seperate sheet with that warning wasn't supposed to be included. Gabe, if you should happen to read this, you might want to call one of your retailers (I got mine from Jab-Tech) that have the stackable radiator in stock, and ask them exactly what pieces of paper they have in their boxes. Make sure you are super clear that a sheet that just has the warning about screw lengths isn't what should be there. It should be three sheets of paper detailing the installation instructions.
2. You must be *very very* accurate in the lengths of tubing that you cut for the small fittings. If you're going to screw up the length, do it shorter rather than longer. If your tube is cut even just a touch long, the snap rivets won't be able to seat correctly. Trust me on this. :)
3. The tubing junction should either have two wider worm gear clamps, or four of the small ones included. Centering the narrow gear clamp so that it gets equal purchase on both of the short fittings is not easy. Especially if you cut your tube 1/16" too long. It would be much more secure to have two of the small gear clamps on each fitting. OK, that sounds confusing. Let's just say it would be great to have a total of four worm gear clamps, just like the two that are included.
4. The extra rivets came in handy. This is also why it's best to err on the short side on the tubing. The rivets are completely dependent on seating *ALL* the way in order to provide a good attachment for the fans. If your tube is cut even ever so slightly long, this isn't going to happen, and the rivets will not be holding nearly as well as they should. Unfortunately, I cut my tubing a bit on the long side. The rivets at the other end of the rad were able to get a good seat, but as you work closer to the fittings end, a gap becomes visible and widens til you get to the last fan mounting holes, which really have a nasty gap. Totally my fault, and easily fixed, either by making sure you cut the tubing correctly, or talking Gabe into bumping the price of the rad up a few bucks and giving us pre-cut lengths for both 25 mm fans and 38 mm fans.
5. Amazingly, my flow rate did not drop at all after installing the second rad. I had exactly one GPM prior to installing the second radiator, and that's exactly what I have now. Pretty wild... I don't know how it's possible, but I double checked the flow rate.
6. Great temp results so far. I had six fans on my single MCR320-qp-k, but right now I only have three total on the rad sandwich. I have six more on order so that I can totally max out the rad sandwich with nine fans. So right now, I've lost three fans but gained one radiator. My temps have dropped 5 C at idle, and 8 degrees when loaded. I'm expecting that adding another six fans will change those numbers quite a bit.
7. The inside of the radiator was totally clean. I flushed it like crazy, and got absolutely nothing out of it.
All said, I'm very happy with it. Thanks Gabe and Swiftech!
pneubmatic What system do you have (specifically, whats under water)? I have $122 in my wallet, of which is the exact I need for extra fans/stackable rad... Is it worth the buy? I'm starting to think it is.
core i7 920 OC'd to 3.6 and a single EVGA GTX295.
Water blocks are a Swiftech Apogee GTZ and EK GTX295 wb., then of course the rad sandwich, which is 2 Swiftech MCR320's. This is all one loop, btw.
I've only been running the stack for just over a day, but I'm very pleased with it so far.
Guys how does a Swiftech MCR220 sandwich compare to one Feser 240 rad?
While I haven't seen official tests, it would stand to reason that the Swiftys would kick the crap out of Feser. One Swifty is at most 8% off the best rad. IIRC another rad will add at least 50% more to the first Swifty.Quote:

I agree that 4 clamps would be ideal, unfortunately there is not enough room for that (if you use 25mm fans in between the rads).Quote:

Using one clamp over 2 barbs sits the band true over the barbs. We didn't find that centering the clamp was particularly difficult to accomplish, so didn't see it as a problem.
If anyone has a better solution, let me know.
I have practical issues with that, issues that I couldn't fix at the time of release:Quote:

We released the stackables following demand from XS members.. so it was a trial, and we made a small quantity to test the market. If the product takes off, then I'd would certainly be inclined to provide precut tubing.
8c at load, now thats what I am talking about :woot: glad to see I wasnt full of it when I came up with this stacking :D
OK, to start off, this is exactly why I will continue to buy and use Swiftech products. It's not often that the CEO of a company will come to a forum and give responses to his customer's concerns. Yup, you may call me an official Swiftech fan boi now if you'd like. :)Quote:

I completely understand what you're saying about including the tubing. Hopefully the new rad will take off and you'll be able to justify the additional expense.
Now about the worm gear clamps... I was able to find some small enough that you could put two per fitting on the MCR320 rad sandwhich. However, the max OD they will accommodate is 5/8". I got them at Home Depot. They are labeled "Ideal Stainless Steel Hi-Grade Nickel Alloy SAE SIZE #4, model No. 62604" They will work on Tygon tubing that is 1/2" ID X 5/8" OD. I am using 25 mm fans, too. Scythe SFF21G's to be exact.
Thanks for your response, Gabe, and thanks for the outstanding products, too.
I agree, i had a lot of people telling me it wouldnt work and even run hotter:shakes:Quote:

Thanks for releasing this product evolution. Glad you listen to your customers.

I haven't seen you post much these days Ian, and I was wondering about you..glad to see you are still active in the community, and good luck with your upgrade!Quote:

Mine are on the way so I'll give feedback once I have them in hand. I've only ever had an MCR120 in hand before...
Hmmm... interesting... I figured when Gabe posted this that the diagram, not his text, was the correct number...Quote:

It would have been nice to see the "Stack Radiator" designed so the screws can simply pass all the way through the finned portion so you can just pass a screw through the entire rad and fans, and into the other rad.
Edit: Also, Gabe... would it be possible to have a "Serial Stack" radiator made ?
What I mean is... the regular MCR if you look directly at it, has a V-shape between the two barbs... if you simply designed the top of the Stacking radiator so one barb is moved to the center of that V, you could stack these in a serial configuration without worrying about fitting compatibility or clearance, or using special fan shrouds to gain enough spacing.
