    Default Radiator Sandwich / Stacked Radiators / Double-Radiator Thread

    The subject of stacked radiators came up in a different thread, so I'm opening up this one for everyone who would like to discuss stacked radiators.


    This post is reserved for me! :-)
    I'll post some test results here later.

    But I'll show you what a radiator sandwich can look like (here using two Magicool Slim 360s):





    Here is the initial testing I did with the radiator-sandwich:

    Test setup:
    In my test setup, I'm using some pretty low-end cooling, which has to do with an article that I built this setup for.

    - Q6600 @ 3.2 GHz with Nexxxos XP Waterblock
    - HD 4850 with EK FC Waterblock
    - XSPC X2O 400 Pump
    - Magicool Slim 360 radiators
    - three Nanoxia fans

    I ran this setup first with just one of the Magicool radiators and then with a radiator sandwich structured as Radiator -> Fans -> Radiator.
    Here are some impressions of the sandwich:










    Testing method:

    I run Furmark to load the GPU and Prime 95 to load the CPU for 45 minutes to warm up. Then I run it for another 20 minutes during wich I log all temperature data in five second intervals. The data of those 20 minutes is then averaged out to get the results.

    Since we're testing radiators here, the most relevant temperature difference is that of water-air.

    Here's the results:


    I tested once with 750rpm and once with 1400rpm. As we can see, the sandwich gains a good two to three Kelvin over the lone radiator. This also translates to lower CPU- and GPU-temperatures.
    As you can see, for the radiator sandwich it doesn't seem to matter what fanspeed is used. Since the T-Balancer, the device I use for temperature-logging has a resolution of only 0.5 degrees, we're certainly not seeing the whole picture here. But I guess we can say that stacked radiators are less sensitive to fan speeds than lone radiators nonetheless.

    As for flowrates, the additional radiator made them drop by 25% in my testing.


    I also measured CPU-Temperatures with the stacked rads agains a Thermochill (this was in a slightly different setup but using the same testing methods):

    Temperature difference CPU-Ambient:







    Scenarios for further testing:

    After I posted this test, a lot of interesting suggestions came up. Here's a list of all of the ideas that should be tested. Please contribute! :-)


    - Two radiators separately vs. stacked radiators
    - Stacked radiators with a total of six fans
    - Stacked radiators with a total of nine fans? (Overkill?)
    - Stacked radiators vs. PA120.3 (testing in progress on this one)
    - Airflow going from first to second radiator vs. airflow going from second to first radiator (as discussed in posts 29-33)
    - Radiators stacked right on top of each other: Radiator -> Radiator -> Fans
    - Running stacked radiators in paralell

    Cheers,
    Shane

    Here you go fellars, any comments or input feel free fire it up. I'm sure Hesmelaugh is eager to share his experiences on this department, he's already ran some test on this project.

    I mentioned Swiftech is coming out a stacked rad or sandwiched rad, whatever they're going to call but it's coming. That the word from Gabe (Swiftech CEO), the release date probably after New Year or February?

    In the mean time you can DIY double deck radiator like the above image.
    Here are pros and cons of double deck rad;

    Pros:
    1) cheaper vs. Feser or Thermalchill
    2) less fan can be use
    3) quiter
    4) better performance than single rad

    Cons:
    1) difficult with the fitting
    2) large fulltower case is a must
    3) good intake air flow path needed
    4) 90 elbow fitting is a must or some moddification need if you don't want to use elbow fittings

    So, are these held together with screws with hex heads or similar?

    I've seen a test on this somewhere...probably HES ...The reduction in performance seemed to be small if I recall but the test was incomplete.

    This would really suit my upcoming build. any thoughts on type and speed of fan needed

    Edit I was right ...it was shane that I read before on this

    if you use hex head screw then it's easier to attach the rads together by using alen key wrench.

    IMO, 1000 - 1200 rpm fans are good enough for this setup, because the fans are sandwiched in the middle, remember the purpose of this setup to use two afforable rads instead of one xtreme expensive and use only 3 fans instead of all 6 fans. The goal is to get high performance, affordable and quite.

    Let do cost comparison shall we?
    Feser 480 $168USD
    Scythe S Flex 4 x $17 (average cost) $68
    Fitting 2 x straight bard $6, 2 x 90 degree bards $13 = $38
    Total cost: $264

    Swiftech 320 x $68USD = $136
    Scythe S Flex 3 x $17 (average cost) $51
    Fitting 2 x straight bard $6, 2 x 90 degree bards $13 = $38
    Total cost: $225

    The reason I choose Swiftech because two MCR320 equal one Feser 480 (surface area), all we need to know if two Swifty can beat Feser?

    Rad dimensions:
    Feser: 527mm x 123mm x 62mm (LxWxH)
    Swiftech: 410mm x 128mm x 34mm (LxWxH) time two on this.

    The down fall of using two Swifty is the overall thickness of 93mm is minimum

    - Two radiators separately vs. stacked radiators <-- interest to see this test
    - Stacked radiators with a total of six fans <-- I'm sure it won't make much different in temp
    - Stacked radiators with a total of nine fans? (Overkill?) <-- defeat the goal purpose, to be cheap and quite
    - Stacked radiators vs. PA120.3 (testing in progress on this one)
    - Airflow going from first to second radiator vs. airflow going from second to first radiator (as discussed in posts 29-33) <-- not much performance effect
    - Radiators stacked right on top of each other: Radiator -> Radiator -> Fans <-- definately need high CFM fans for this
    - Running stacked radiators in paralell <-- interest to see this test

    Cheers,
    Shane
    As the results indicated, stacked radiators will out perform a single rad and Thermochill PA120.3 by 1c - 3c.
    Let justify the performance value between Hesmelaugh stacked rad vs. Thermochill PA120.3;

    Thermochill Stacked Rads
    PA 120.3 2x Magicool Slim 360
    3x Scythe SFlex Fans 3x Scythe SFlex Fans
    2x Standard bards 1x Standard bard, 3x 90 fittings
    Total Cost $157 Total Cost $229
    Performance value: $72 per degree

    Therefore, we (at least me ) like to see the test opitions in red to be conducted.

    My prediction is Thermochill or Feser rads will be better choice after all for first start out setup, if you guys have something like this in mind, unless you have some old rads laying around and want to put it to use. I don't think it is worth to start a new setup like this.

    Where do get those prices from?

    If I calculate the prices from Aquatuning (Germany), where I get my LC stuff, it looks like this:

    Thermochill: 90 Euros
    2x Magicool: 74 Euros

    Two fittings: 3 Euros
    1 fitting and 3 90 fittings: 10 Euros

    Total Thermochill: 93 Euros (135 USD)
    Total Sandwich: 84 Euros (123 USD)

    I left out the fans on purpous since you need three fans either way and their price depends on your preference.
    So with the prices I get here, the difference in price may not be huge, but the stacked radiators give you superior perfomance and save you a couple of dollars!

    Prices was based on PerformancPCS, FrozenCPU & NCIXUS.COM price list.

    Thermochill 120.3
    $140 (NCIXUS)
    PerformancePCS out of stock, and FrozenCPU don't event carry Thermochill any more, they carry Feser instead.

    Magicool Slim 360 Pro
    $70 PerformancePCS

    Scythe SFlex
    $17 PerformancePCs or $15 FrozenCPU
    I picked the fan because it cost in the middle, yes you can go with $10 one or $30 one, your choice.

    Bards
    Swiftech standard $6 pair PerformancePCs & FrozenCPU
    Bitspower 90 fittings standard bard $14 each (not the compression)

    My estimate was a ballpark figures, people may shop around and get better prices.
    The following are major water cooling suppliers, that is where most us shop in the North America

    PerformancePCs
    FrozenCPU
    Sidewinder
    NCIX

    Their prices are relative within $2-$3

    but the stacked radiators give you superior perfomance and save you a couple of dollars!
    how can you say superior peformance?
    the test results only showed 1c better than Thermochill, no agurement with the same type of rad as single here. Unless I missed understand your results :confused:

    See, if all your test scenarios conduct and concluded then we can determine what the best setup is but at the moment it is the best idea to save $50-$70 to gain 1C, to do this type setup from scratch. That is why I mentioned in the previous post, if you have spare parts then it's a good solution.

    I was planning to do something like this with my next i7 build or just use Feser Xchanger 480. Also, I'm very interesting to see the Swiftech new double thickness rad coming out soon.

    antoher idea of stacked radiators: 120.3 + 120.2+120.1 this would save you on using 90 deg fittings what d you think of it??

    If anyone really does want to see the 9 fans test I hope to be picking up another pa120.3 in january and I already have 16 high pressure (3 blade) Delta EFB1212SHE 120x38mm fans which, due to the lack of controller, I have tested at 12v, 6v and 4v which they handle ok (no problem starting)

    It ought to be possible to select the rpm/cfm of your choice.....I know the fact that I'm proposing to use thermochill somewhat defeats the object but let me know if I can help with anything here

    well, you can stack as many you like but in this scenario you have to use 4 fans (3 between 120.3 & 120.2, 1 between 120.2 & 120.1, if you don't use one extra fan then one of the fan probably to weak to pull or push the hot air) and the total combined thickness will be over 110mm. What case do you think it will swallows this setup?

    The flow restriction will be higher than two 120.3 stacked, the performance might be taxed as well, probably not much though.

    why not?
    you can conduct the experiment with two PA120.3 with 3 120x38 fans or 6 or 9 and do the comparison with a single PA120.3 with 3 fans or 6 fans in pull/push fashion. Of course you have to do it with different fan RPM setting.

    Shane, what's the CFM on the 120mm fans your using for your test set up? Have you found that by using a higher CFM fans, that they lowered temps, and if so, by how much?

    Thanks

    Default Radiator Flow Tube Design

    I illustrated the two typical tube flow designs to show you how they work, so if you decide to do stacked setup to simulate the highend radiators.

    Most highend radiators use Dual tubes flow design, such as ThermoChill PA series, Feser Xchanger series or HWLabs 480GTX. Two layers of multiple tubes for Inlet flow and Outlet flow. This design out perform the Single flow design because it uses double amount of tubes and surfaces area.

    If you look at Hesmelaugh setup pic, he got it right with the tube connection for Signle flow rad (left to right) and you should have the cold air flow intake come from the second rad when the coolant must cooler on all tubes, not only half like the first rad. This way you won't have hot air blowing at the cooled rad.

    So if you have two Dual Flow Tube design rads stacked, they will out perform the Single Flow Tube rads stacked setup. The problem with this that no cases will fit with this setup unless you do external installation.

    The fans are quoted at 47.4 CFM.

    If you look at the last graph in the first post, you see the results with full and roughly half fan speeds. As we can see, the stacked radiators as well as the highend radiator make a bit more of a difference at lower CFM.

    This makes sense to me since the closer temperatures get to ambient, the more extra effort is needed to remove more heat. I can't remember what this correlation is called but it's basically the opposite of exponentiality. Along a line of increasing CFM you will get a temperature curve that flattens out infinitely as it approaches ambient.

    Next year, we should try this out with the new Monsta's. 9 fans pushing / pulling air through them should be enough as long as the fans have a high enough static pressure. Have to build its own external enclosure for it though, no way that would fit inside a case without some major modifications.
