Silverstone PF360 All-In-One Liquid CPU Cooler Review

Silverstone has been around since 2003 and have a sizable stake in the PC chassis, power supply, CPU cooler, fans, and accessory markets. Personally, I was first introduced to them as a top tier PC case manufacturer, and I still have and use some of their older cases such as the PS07, TJ08-E, and the TJ07. Today, however, we have one of their all-in-one liquid CPU coolers up for testing, the PF360. The PF360 is a large 3×120 mm CPU cooler featuring addressable RGB on both the fans and pump/block housing.

Features

Water block includes a pump with a multi-chamber design that isolates hot and cold liquid channels to prevent heat bleeding, thus making it more effective at removing heat away from the water block.
The pump motor utilizes three-phase, six-pole design for smoother, quieter operation compared to most single-phase, four-pole designs. Energy efficiency also improves as well.
0.2 mm micro liquid channels evenly distribute liquid flow for improved heat dissipation.
An automotive-grade sine wave generator is used to drive the pump motor. This ensures electrical noise and vibration are kept to a minimum. It is also AEC-Q100 certified according to Automotive Electronics Council’s standard so it has great quality and durability.
Automotive-grade radiator is used so it has excellent anti-corrosive properties and can easily survive harsh elements that include vapor, liquid, grease, solvent.
Included PWM fans have unique ribbed edge fan blades that suppress air turbulent noise with geometry optimized for both air flow and pressure. This ensures maximum performance with the lowest possible noise.

Packaging & Accessories

Silverstone’s packaging has a nice shot of the PF360 on the front of the box along with their branding, cooler model, and supported ARGB motherboard brands towards the top right corner. On the back of the box, we have a detailed specifications table along with a schematic showing dimensions for the radiator and pump/block combo. Lastly, there are also a few features mentioned on the back and one side of the box to fill out the presentation with some more information.

Accessories

Silverstone PF360

The PF360 is a great looking cooler with an almost entirely matte black finish, except for the ARGB lighting, translucent fan blades, and a few Silverstone snowflake logos. The tubing has a woven braid sleeving and is heat shrunk on the ends giving the cooler a more finished appearance. The ARGB lighting looks good and I especially like the recessed pump lighting illuminating the Silverstone logo on top of the pump.

A Closer Look

The radiator is made out of aluminum and 28 mm thick with a fin density of around 22 fins per inch. Being a 3×120 mm AIO unit, the radiator is large and will most likely need a large case to support it. The tubing is 400 mm long, which should be plenty of length for mounting the radiator at the top of a case. The rubber tubing has a woven sleeving covering its entire length which gives it a nice aesthetic to complement any build theme.

Radiator & Hoses

The top of the pump/block housing has a mirror-like hexagon where Silverstone’s logo will appear when using the ARGB on the pump/block. The base of the block has a smooth, matte finish where some reflection can be seen, but it’s definitely not a mirror finish.

Three APA1225H12 120 x 25 mm fans are included with the PF360. These PWM controlled fans have nine blades with speeds varying between 600 and 2200 RPM. They also make use of addressable RGB connectors for LEDs located on the hub beneath the translucent fan blades. It’s great to see that the fans have foam corners to help suppress any noise that could be caused by vibrations.

Installation

The mounting process was pretty intuitive. The first step was taking the backplate and feeding bolts through the correct holes for the socket.

Backplate

Screws

Once the bolts were in place, press-fitting plastic washers were pushed down the shafts to hold them in place while feeding the backplate through the mounting holes on the back of a motherboard.

The next step was to press-fit tall spacers onto the bolt shafts to secure the backplate to the motherboard. Then, applying thermal paste to the CPU and placing the pump/block combo onto the socket.

Block/Pump Mounting

Spring-loaded thumbscrews are used to secure the pump/block to the socket and provide even pressure over the surface of the CPU.

ARGB Control Box

Below are a couple of excerpts from the manual about connecting the RGB lighting cables and controlling the lighting via the control box. If you’re connecting directly to the motherboard, then you’ll need to check your motherboard’s manual for details on controlling RGB lighting.

Methodology

All testing was performed on an open test bench, which minimizes ambient temperature and gives a “worst case” scenario for sound level.

Cooling performance was tested as follows:

  • Disabled all BIOS settings that cause the CPU clock speed and/or Vcore to fluctuate (although there was still some Vcore fluctuation under load).
  • Ambient temperature was measured with a Fluke 52 II at ~1 inch from the intake fan(s). Then, subtracted from the recorded temperatures to get ΔT.
  • Varied Vcore (in BIOS) from 1.125 V to 1.375 V in 0.050 V increments to increase heat. Stopped increasing Vcore once a core reached ~100 °C.
  • 20-pass 2048 MB RAM LinX runs at each Vcore interval were used to load the CPU.
  • CoreTemp was used to record minimum and maximum core temperatures.

The sound level in dBA was measured 10 cm from the intake fan with the fan speed set to 100%. Then, the sound level was estimated for other distances using the following formula:

L2 = L1 – 20 * log10(r2/r1)

  • L2 = dBA @ desired distance
  • L1 = dBA @ reference distance
  • r1 = reference distance
  • r2 = desired distance

Why estimate sound level instead of measuring at further distances? It’s because the meter I’m using is most accurate between 40-130 dBA, so I needed to measure really close to the source to make sure my readings were within that range to get the most accurate measurements.

Results

Cooling Performance

The PF360 performs well but doesn’t really stand out among the other liquid coolers that I’ve tested. What I’m getting from my results when comparing the smaller AIO units to the larger units is that the performance isn’t that much different. I believe this is due to diminishing returns and shows that a large water-cooling loop isn’t needed to keep just a CPU cool. The smaller ones can do almost as well as the larger ones with only ~3 °C difference on average between the 2×120 units and the 2×140/3×120 units.

Sound Level

Along with the Enermax Aquafusion, the PF360 is easily one of the loudest coolers when running at 100% fan speed. As always, I like to remind readers that these numbers are worst-case scenarios with the cooler on an open test bench with fans maxed to be as loud as possible, so not at all typical usage. The PF360 is definitely not a cooler you would want to run at full blast. Fortunately, with the PF360 being so large and with diminishing returns cropping up in the performance results, this means there should be room to reduce the fan speed without sacrificing much in performance.

Conclusion

Silverstone’s PF360 is a visually pleasing AIO whether using RGB lighting or not. The matte black finish along with braided tubing looks great and complements any theme, while the ARGB adds a pop of color if desired.

As for performance, the PF360 does a good job cooling the i7 8700K. Although, I believe in most cases a cooler of this size is overkill for a CPU alone since the results show minor temperature differences between larger AIO units and the smaller ones. Noise could be an issue when running the fans at max speed with the PC close by, but maximum fan speed shouldn’t be needed with the PF360’s large radiator.

The price for the PF360 comes in at $129.99 on Amazon and NewEgg which isn’t much more than 2×120 mm AIO units out there. So, if you’re using a notoriously hot CPU and have the space for a large radiator, then the PF360 could fit the bill without much more added cost.

Overall, I’d say the PF360 performs well while looking great doing it, just make sure you have space and keep the fans turned down some. However, I think most people could get away with using a smaller unit such as Silverstone’s PF240 or other 2x 120 mm AIO.

  1. Copper base and aluminum radiator...Is the tubing in the radiator tubing copper lined? I'll admit my liquid cooling knowledge is limited, but I thought it was a bad idea to mix metals in a loop?
    Copper and aluminum get along quite well. American pennies are aluminum clad with copper. They have similar electronic properties, similar outer shell electron configurations, and don't oppose anodically. The problem comes with 'dirty' water in a loop, i.e., when non-distilled water is introduced it frequently has other metals such as calcium or phosphates, or could have reactive chlorine. That's where the trouble begins.
    ˄˄ Correct sir, I apologize to all for the brain fart. The only aluminum pennies made were later destroyed by the US Mint sometime in the 1940's when they started making steel pennies for a while.
