What happens when a company takes its most silent fans and slaps them on an equally advanced AIO package? Well, you get the SilentiumPC Navis F240 AIO, which promises an incredible price performance ratio. It can be had in either stealth/all-black flavour or with ARGB fans.

SilentiumPC was established in 2007, Warsaw, Poland. They build high-quality silent PC cases, power supplies and cooling solutions that simply get the job done without breaking the bank. They accomplish this by the old-school belief that good products are the key to success. No aggressive marketing, no flashy banners everywhere, no mighty slogans. Instead they’re putting efforts in effective design and smart cost-cutting so the customers get the pure essence of functionality at unbeatable prices.

 

Prices and Availability

 

With an MSRP of just £74.99 for this promised quality tier level, it beggars believe. The ARGB variant is just £10 more. This will pose serious competition to the top end air coolers because some of those cost even more than the Navis F240 AIO.

 

Presentation and Specifications

The SilentiumPC Navis F240 is a new high-performance AIO CPU cooler designed in collaboration with Synergy Cooling. The ultra-silent asymmetrical PWM controlled ceramic-bearing block-pump is paired with a 240mm radiator with two pre-installed Fluctus 120 PWM fans. The Navis F240 Series is designed for the most demanding users, those who expect not only exceptional performance but also near silence. In terms of cooling efficiency, the Navis F240 series ranks among the top 240mm radiator systems, yet also features a drastically improved acoustic experience. The cooler is compatible with AMD AM4 and popular Intel sockets, including the latest LGA1700 platform. The entire kit is covered by a 36-month manufacturer’s warranty.

 

Visual Inspection

 

The shipping livery is the same across their recent line-up with a visual depiction of the actual product on the front, on a white background with blue accents.

You get a detailed list of the AIO’s main highlights and some of the specs for the rad, pump and fans.

There is decent protection coming from this combo of cardboard and plastic pads and bags.

When it comes to accessories, the list is minimal since the mounting hardware is versatile since for the Intel sockets you get a multi-purpose backplate and while for AMD you just reuse the AM4 stock motherboard backplate.

Thus we have:

1x Highly detailed instruction booklet
1x Intel multi socket backplate with preinstalled grommets
1x 4-pin PWM extension cable
1x Mini custom wrench
1x Mini thermal Pactum PT-3 paste syringe
4x Intel custom double threaded screws
4x AMD custom double threaded screws with plastic washers
4x AMD retention pump springs
4x AMD locking nuts

Right, here is the SilentiumPC Navis F240 AIO, which of course is a 240mm AIO from its 2x 120mm included fans. It has a sleek all-blacked out design which will make it a perfect solution to any stealth build.

The sealed aluminium radiator measures exactly 275(L) x 120(W) x 54(D) mm while the pump is just 48.5mm tall and 95 by 90mm (including the exiting tubes and integrated installation brackets).

The exiting tubes have a nice set of reinforcements at the ends and are covered in this braided nylon sleeve. Overall, you get 390mm of length for the tubes which is plenty for a wide range of enclosures.

We highly appreciate that the fans are already preinstalled out of the factory, thus more steps towards a truly plug and play solution.

It uses the same famous Fluctus 120 PWM fans that we saw on the Fera 5 CPU air cooler which are rated up to 1800 RPM. With the help of their serrated and aggressive looking 9-blade design, they should push a decent amount of air albeit we have no official specs numbers here.

The fans takes power via 4-pin un-sleeved 200mm long cable with a built-in PWM 4-pin splitter for a second fan, which is 130mm long, perfect to daisy-chain them on the AIO.

Finally, let’s focus on the pump. The minimalist and elegant design is present here as well, with just the “S” logo for SilentiumPC positioned in the middle of the brushed finish top cap. The exiting tubes have plenty of swivel in each direction.

Kudos to the integrated installation brackets that are part of the pump’s overall construction. Apparently the pump uses ceramic bearings and its operating range is between 1600 to 2600 RPM. It takes power from a SATA port and signal from the 4-pin PWM plug.

The Navis F240 supports all of the main and most popular sockets in today’s market (minus stuff like LGA1366, TR4 or the OLD AMD FM series) which is understandable given its price and its integrated mounting system (that makes more practical sense).

 

Installation

 

Since we are on an AMD platform, that means for the AM4 socket, you have to reuse the stock motherboard bracket. Then as we saw, the pump has the brackets integrated plus the fans being already preinstalled, all of these translates to as close to a ‘plug an play’ experience as you will ever encounter with an AIO.

Our test enclose for today has changed since last time (which will be reviewed soon as well) so this will be an extra challenge for the Navis F240 AIO because it will be mounted in an ITX build.

The first step in accordance with this particular Phanteks case, is to attach the AIO using the fan bolts to the removable tray. Luckily the supplied bolts from the Navis F240 are long enough.

Even the wires are pre-arranged from factory so just attach the supplied extension cable if you need the extra reach to the motherboard.

This enclosure, due to its design, requires an AIO with quite bendable tubes to clear the designated location. As you can see, the Navis F240 has your back here as well.

Right, now we can focus onto the socket area. After reusing the stock backplate, install the custom double threaded securing bolts.

You will need to lock them down properly using the included wrench and then apply the thermal paste

Place the pump which you can do in either orientation – tubes close to the RAM or facing the VRM area. We did both to find the best route within this case and to check for any potential clearance issues.

Place the retention springs and bolt down the securing bolts in an X pattern .

Attach the pump’s 4-pin plug to the motherboard’s AIO header, the fans to the main CPU header and lastly the pump’s SATA connector.

This is the final result and happy to report that there are no clearance issues even in this small environment.

Everything clears so we can finalize the build by attaching all of the panels.

 

Testing methodology

 

  • The CPU cooler will be tested in 3 different scenarios as follows: the AMD Ryzen 5 5600x CPU at stock settings, then at 4.0 GHz for 1.05v (as the main baseline to remove any inconsistencies in stock form where the BIOS will pump extra voltage for shorter periods) and finally an overclocked scenario of 4.7 GHz for 1.275v
  • As the main torture test, we will employ a 2 minute run in AIDA64
  • Room temperature was recorded at ~20°C
  • For the noise testing, we used our Pyle PSPL01 placed 30 cm away from the setup – all other fans will will be off or set at minimum RPM and a lav mic was places at the same distance for the audio sample
  • Thermal paste used Noctua NH-H2
  • All of the side panels will be attached and the F240’s fans will be left on auto % RPM to simulate real life usage or manually adjusted and pointed out accordingly
  • Any results over 90°C in any condition are considered a fail

Testing, Results and Analysis

 

The first series of tests come from Cinebench R23 which will put a serious load on the CPU while it renders a specific frame. From top to bottom, as mentioned above, the 5600x CPU will be tested in the following sequence: 4.0 GHz @ 1.05v, stock settings and OC’d to 4.7 GHz @ 1.275v.

The 5600x despite its ‘official’ 65W TDP rating, we all know, since the release of 3000 Ryzen series from AMD, that it will not respect that when it boosts. Thus, this is a hot CPU even in stock form. To further point out that there is no additional airflow in this ITX enclosure and the AIO acts as an exhaust to the entire build, the temps are really good even in the OC scenario.

The 2 minute long AIDA64 stress test should impose the maximum workload just for the CPU, therefore we should get the highest stress scenario.

Nothing new to report here that the AIO is more than capable to handle these specs and circumstances.

If a CPU cooler manages to survive the torture tests, then a benchmark run in a gaming scenario, should be a walk in the park. Games are not as stressful as a synthetic torture tests but are a great indicator of real life usage.
Assassin’s Creed Valhalla averaged around 40-50% total CPU usage in all CPU scenarios and thus the SilentiumPC AIO cooler barely flinched. Check the video as well for the complete perspective.

The noise output test is an important challenge for any CPU cooler since if you can’t live with the noise, this negates any of the other advantages. Well, the pump is extremely quiet even at 100%! You can have a listen in the video. Then the Fluctus fans perform as we expected, silent even in mild load. Thus the SilentiumPC Navis F240 AIO has a clear win here as well.

 

Conclusion

 

This AIO proves to be the perfect example of a ‘straight to the point’ philosophy. You want an excellent performing all in one solution that is capable, quiet, affordable and easy to install? Then buy this Navis F240. Job done. They made life easier by designing the retention brackets into the pump’s body and even attached the fans to the radiator while routing the cables as well. Also if you want the extra bling, they provide the ARGB variant as well, which is basically the same AIO with different fans. So this is truly a best value champion!

The good:

+ Incredible price/performance ratio
+ Excellent cooling & acoustic results
+ Superb build quality
+ A really plug and play AIO solution

The bad:

– Low availability outside of Europe
– Socket support covers only the main and most popular current options
– Still no full info on the specs regarding the Fluctus fans
