Overview

 

After recently fitting the be quiet! Silent Loop 280 into the be quiet! Pure Base 600 I was excited to take a look at be quiet’s latest and largest AIO CPU Cooler. This is the be quiet! Silent Loop 360mm an AIO liquid cooling solution with a massive 360mm radiator. The be quiet! 360 is (somewhat obviously) equipped with a 360mm radiator, the radiator itself is made from copper and is cooled courtesy of the three Pure Wings 2 PWM fans supplied. The Silent Loop 360 supports both Intel and AMD sockets, with the following specific types being supported:

Intel®: LGA 775 / 1150 / 1151 / 1155 / 1156 / 1366 / 2011(-3) / 2066
AMD: AM4 / AM2(+) / AM3(+) / FM1 / FM2(+)

 

bequiet-large ‘With Silent Loop be quiet! brings whisper-silent technology to the world of All-in-One watercooling, making liquid cooling an attractive option for those who want to heavily overclock CPUs for maximum processing performance or cool high-power PC systems.’

 

 

As you can see from the images above the be quiet! Silent Loop 360 arrived in a (very) large predominately black box with a good sized image of the cooler on the front. We can also see that this is a CPU Cooler from be quiet’s premium range and that be quiet! have highlighted the following features:

  • Innovative reverse-flow pump for less vibration
  • Three be quiet! Pure Wings 2 120mm PWM fans
  • Flexible tubes with useful bend protection
  • Refill port extends the product’s life span
  • Compatible with Intel and AMD sockets
  • Looking at the back of the box we see a fair amount of blurb regarding both be quiet! themselves and regarding the Silent Loop 360’s features. This can be seen in both English and Dutch along with what appears to be a token gesture of French!?

     

     

    On opening the box we can see the manual in the top of the box and that everything is is well packaged and adequately presented. As is common for AIO CPU Cooler the standard recycled cardboard packaging is used.

     

     

    Within the box other than the cooler itself and the three Pure Wings 2 fans we find the both Intel and AMD mounting hardware (including AM4 spacers) as well as a 3-way fans splitter and some thermal paste.

     

    At the time of writing the be quiet! Silent Loop 360mm is retailing at Overclockers UK for approximately £150 and comes with a 3 year warranty.

    First Impressions

     

     

    First impressions of the be quiet! Silent Loop 360mm are along the lines of ‘damn isn’t it heavy and wow that radiator is big’. If there was ever a AIO CPU Cooler that looked like it could cool molten lava then this is it. Although the overall look is not necessarily one of ‘cool’ as the pump head of the Silent Loop 360 is more class than cool. Also still not a fan of these outer spring hoops that cover/protect the hose…

     

     

    Looking at that classy looking pump head in more detail we see a nice low profile design. The top of the pump head features a brushed aluminium look with a simple yet elegant silver be quiet! logo. As you can see from the fittings they can also be undone a feature that could prove most useful for the budding modder. The pump itself features be quiet’s decoupled reverse-flow pump that according to be quiet! runs smoother, quieter and with less vibration than conventional pumps.

    The base of the pump features a nickel plated cold plate held in place by four screws. This cold plate is protected with a plastic film that (somewhat obviously, but I’ve forgot in the past!) should be removed before installation. The pump head itself is connected by way of a three pin header, providing 12v to the pump within. Also just next to the cable we find a small port this is in fact a fill port, should you wish to use it.

     

     

    The radiator measures in at a a whopping (H)397mm x (W)124mm x (D)30mm making it the biggest AIO CPU Cooler we’ve yet seen here at pcG. be quiet! have chosen to use a full copper radiator, this coupled with a pump speed of 2,200 RPM gives the Silent Loop 360 a TDP of 450W. Note also that the radiator features the same removable fittings that are used on the pump head.

     

     

    To compliment that massive 360mm radiator be quiet! supply three Pure Wings 2 PWM controlled fans complete with three way fan splitter. This allows the fans to be connected up to a single PWM fan header on the motherboard. Each fan has a maximum rotational speed of 200 RPM and a CFM of 65.51. It’s a little odd that the pump doesn’t control the fan speeds itself!?

     

    Hardware Installation

     

  • Test Rig Setup

  • Case Phanteks Enthoo Luxe Glass Power Supply be quiet! Pure Power 10 700W
    Motherboard Gigabyte AX370-GAMING K5 CPU AMD Ryzen 7
    CPU Cooler be quiet! Silent Loop 360 RAM Ballistix Elite 3466MHz 16GB (x2 8GB)
    Graphics Card Asus GTX 1080Ti “Founders Edition” SSD (M.2) Samsung 960 EVO Polaris 250GB

     

     

    Above you can see all (and there’s a lot) of the parts required for our new AM4 socket installation. This comprised of four bolts, x2 side brackets, four nuts, four washers, four springs. AND: For this AM4 installation we will also have to use the four spacers specifically for AMD Ryzen. In addition to this be quiet! also supply a 3-way fan splitter and a raft of screws for radiator/fan installation.

    Although there are a lot of parts the entire assembly can be completed outside of the Case, which is good news. Fist the side brackets can be slid into position, making sure they clip (it’s tight BTW) together in the middle. Note that the position (there are two) of these brackets means that you’ll also define the position of the be quiet! logo on the pump, so it is worth checking you planned orientation first. Once this is done each bolt can be added including the spacer for AM4. It should be done in the following order: bolt, spring, washer, spacer – now thread through bracket and secure with the nut until finger tight.

     

     

    This can now be secured to the Motherboard atop the CPU thanks to the original AMD back-plate that is still used. The only issue here is that there’s nothing to hold the back-plate in position, so the final assembly turns into a bit of a nightmare, which is s shame… 🙁

    Of course for such a large radiator you’re going to need a pretty big Case, well one that will accept a 360mm radiator at the very least. Luckily our new AMD Ryzen based Test Rig is now living in a Phanteks Enthoo Luxe that’s got plenty of room in the top for the radiator and the three be quiet! Pure Wings 2 fans. With the pump connected to a suitable Motherboard fan-header and the fans (courtesy of the 3-way fan splitter) connected to the PWM controlled fan hub at the back of the Phanteks Case, we were good to go…

     

    Testing Methodology/Setup

     

    For CPU Cooler testing, we here at pcGameware run AIDA64 (System Stability Test) for a 15 minute period. During this period the CPU temperature is monitored via AMD’s Ryzen Master software. A close eye is also kept on the ambient temperature, with the maximum being recorded for each run, this allows us to calculate the Delta temperature (Core – Ambient = Delta). Each run was performed with the AMD Ryzen 7 1700 CPU at the following frequency/voltage: 3.9GHz (OC) at 1.380v.

    * Please note: To ascertain the maximum and minimum noise levels produced by our test CPU Coolers, the dBA is recorded at a distance of 1 metre from the CPU Cooler, with all Case fans unplugged to isolate the sound in question.

     

     

    Processor speed is set using the M.I.T. tab within the Gigabyte AX370-Gaming K5 UEFI, CPU Clock Ratio was changed from Auto to 39. Extreme Memory Profile (X.M.P.) was set to Profile 1 and memory manually adjusted to 32 (3200MHz) as the Motherboard would not post at the true XMP speed of (3466MHz). VCore voltage was also increased via Gigabyte’s offset control (note this is additional voltage not total voltage). An additional voltage of +0.198v was added giving a total VCore voltage of approx. 1.38v.

     

    Hardware Performance

     

    As stated above, to make our performance tests easier to follow and to get the most accurate recordings, all of the following tests have been carried out with all Case fans set at 100% and the three be quiet! Pure Wings 2 fans also set at 100% courtesy of the Motherboard’s UEFI.

     

    • AMD Ryzen 7 1700 @ 3.9GHz

     

    AIDA64 Stability Test @ 3.9GHz


     

    CPU Cooler Air/Liquid Fan Speed Ambient Temperature Max CPU Temperature (core average) Delta Temperature Noise Level
    be quiet! Silent Loop 360 Liquid 100% 23.00 65.00 42.00 54dB

     

    Above you can see the screenshot of the the AIDA64 Stress Test running on the right while the AMD Ryzen Master software is on the left. Note the temperature shown by AIDA64 seems to be invalid, or it might just be the lowest Core temperature!? The maximum is shown on the left in the Ryzen Master software and this value was used in testing. CPU-Z also confirms the 3.9GHz Core Clock as well as the VCore voltage of 1.380v, the memory was also running at 3200MHz.

    Now I have to confess that this is our first test with our new AMD Ryzen setup so for now we only have one temperature to go by. I will add more here each time we do a new CPU Cooler test. But what I do know is that more voltage could be added should you wish and the be quiet! Silent Loop 360mm would be more than adequate.

    With all of the fans at full speed the be quiet! Silent Loop 360 is far from quiet! But thanks to the UEFI control this can be controlled and set to your desired level. At 100% fan speed (as used in the test above) we recorded a total noise output of 47dBA, that’s pretty loud and verging on too loud, but bearable while in Game with a Headset on IMHO. This dropped to 43dBA (far better on the ears) when the fan speed was set at 50% (1000 RPM) and cooling performance only dropped by two degrees.

     

    Final Thoughts

     

    There’s a lot to like when looking at the be quiet! Silent Loop 360mm as it’s a good looking, well made AIO CPU Cooler. Ok, so the installation is a bit too fiddly for its own good but if you need the cooling potential offered by a 360mm radiator then I’m sure you’ll get over it…

    The be quiet! Silent Loop 360 arrived at pcG in a large predominately black box with the usual eco-friendly recycled cardboard packaging that now seem to be synonymous with all AIO CPU Coolers. Of course the box needs to be big as this AIO packs a massive 360mm radiator into the mix; the clue’s in the name I guess. There appears to be plenty in the box thanks in part to the weight of it and the fact that not only is there a 360mm AIO CPU Cooler but there’s also three 120mm be quiet! Pure wings 2 fans and a raft of mounting hardware.

    It’s relatively obvious that the Silent Loop 360 is big, but it’s still a good looking cooler, well the pump head is at least. The hoses themselves are outfitted with the spring like covers (bend-protection) that helps to protect the tubes from kinking. It’s a good idea but it still looks ugly IMHO and I’m not sure it’s really needed.

    Installation didn’t get off to a good start as there’s so many parts required and there’s an additional four spacers required for our new AMD Ryzen based test rig. Thankfully all of these parts can be pre-assembled to the pump head before installation, which is really pretty neat. This would have made the actual fitment of the cooler atop the CPU easy if it wasn’t for the fact that there was nothing to hold the AMD back-plate in position. This results in the need for around three pairs of hands and Spider-Man like grip. But, we got there in the end…

    Performance wise the be quiet! Silent Loop 360 had no problem cooling our overclocked (3.9GHz) AMD Ryzen 7 1700 CPU. With all fans at 100% (2,000 RPM) we measured a maximum CPU temperature of just 65 degrees Celsius during our AIDA64 System Stability test. This also only increased by two degrees when we drooped the fan speed to 50% (1,000 RPM) which was far more pleasant on the ears at just 43dBA.

    Summing up; the be quiet! Silent Loop 360mm is not only a big AIO CPU Cooler it’s a good one too. But at £150 it is expensive and there’s little to fall in love with here. The tricky installation needs to be improved and maybe we should have some LED RGB lighting too (well it’s now on everything else, after all!). But if you want a lot of cooling, then once installed you’re going to be happy with the be quiet! Silent Loop 360mm.
