PCCOOLER has provided screws and related mounting hardware in separate transparent containers. Each container is labeled for ease of identification.

20220517 122704 Copy

We have a plastic-made backplate for the Intel platform.

20220517 122734 Copy

The backplate has two self-adhesive strips. These will hold the backplate in its place during the installation. Personally, I am against the idea of using anything which requires pasting on the motherboard area.

PCCOOLER has provided:

  • 2x Intel Mounting Brackets
  • 2x AMD Mounting Brackets

It is time to take a closer look at the cooler. The PCCOOLER PALADIN S9 is compatible with Intel 20xx/1700/1200/115x and AMD AM4 sockets. PCCOOLER has mentioned this cooler to be able to handle thermal dissipation of up to 250W. The dimension of the cooler is 130×136.5x156mm (LxWxH) where 156mm is the height of the cooler.

20220517 123058 Copy

We have a total of 48 aluminum fins stacked up. It is a standard sort of layout. Both towers are identical in layout. The heatsink is following a stepped design. We have 43 fins on the top followed by 5 fins in a recessed design. This is done to ensure the maximum clearance for high-profile RAM. The tower without a fan has clearance for up to 44mm or so RAM height.

20220517 123027 Copy

The fins are in a straight line manner and there is no v shape notch or any other peculiar design element in the heat sink. The front and rear sides are identical in layout. The surface of the heatsink has insets at regular intervals. The complete assembly is black color coated which is done using the black electrophoresis (EP) process.

20220517 122940 Copy

The left and right sides of both towers are identical. The outer sides have insets. This is where the metallic fan clips are attached to secure the fan on the heat sink. The fins are jointed on the sides.

20220517 123459 Copy

Both towers feature stylish plastic covers. The PCCOOLER branding on both covers is A-RGB backlit. The rest of the cover top is in black color syncing in well with the overall black color theme of the cooler. the edges of the covers are finished in silver color and stepped down design which further augments the overall layout.

20220517 123127 Copy

The PCCOOLER PALADIN S9 is using 6x sintered powdered heat pipes. They are 6mm thick. They are also finished in the same black color. The heat pipes are aligned in a way to have maximum contact inside the heatsink with the fins.

20220517 123245 Copy

There is a small length 3-pin A-RGB connector cable on each tower. This is there to power the A-RGB LEDs under the top covers. Though this is a proprietary connector, the main connector on the fan is a standard 5V, 3-pin A-RGB one. We will cover this shortly.


The above picture illustrates the convection of heat from the base to the top of the heatsink. They are also showing the sintered powered coated heat pipes.

20220517 123303 Copy

The mounting plate is pre-installed on the base of the cooler and it is removable. There is a screw in the middle securing the mounting plate on the base.

20220517 123320 Copy

The base plate has two spring-loaded screws which make the installation convenient.

20220517 123205 Copy

There is a protective cover on the base of the heat sink. It needs to be removed before installing the cooler. The base of the cooler measures roughly 38x44mm. We have a full copper plate making a contact with the CPU IHS.

20220517 123225 Copy

The copper base has a fine polish mirror finish to it.

20220517 122332 Copy

PCCOOLER has provided two 120mm A-RGB fans with this cooler. The fans are 130mm in size and have 9 frosted blades for even transfusion of the light effects. The frame is not circular and has a square design. The hub has a PCCOOLER branded sticker on it.

20220517 122347 Copy

Each mounting corner has a cut-to-size anti-vibration pad.

20220517 122402 Copy

The frame is rigid and there is no arrow marking.

20220517 122431 Copy

The backside of the fans shows the 4-arms assembly on the mainframe with one arm having catchers.  The wires are routed through these catchers towards the exterior of the fans. The fans are manufactured in China.

20220517 122502 Copy

The fans have 4-pin PWM fan connectors and 3-pin, 5V addressable connectors. The cables are flat in design.

20220517 122522 Copy

There is a proprietary 3-pin socket. This is where the proprietary 3-pin connector of the top covers on the heatsink is connected to. PCCOOLER has managed the proprietary connector between the fans and the top covers. The main connectivity with the source controller is done via a standard 3-pin A-RGB, 5V connector. I would say this is a smart implementation.

FDB Bearing

The fans are using FDB bearings which are wear-resistant.

The specifications of the fan are:

Dimension 120x120x25mm
Type 4-pin PWM Connector
Speed 800-1800 RPM ± 10%
Airflow 73.6 CFM
Air Pressure 1.98 mmH₂O
Noise 10~28.6 dB(A)
Rated Voltage 12VDC
Operating Voltage 10.8~13.2VDC
Starting Voltage 7VDC
Rated Current 0.42A±0.03A Max
Power Input 5.04W

Here are the pictures of the assembled cooler.


The height of the sockets on the backplate is reduced as compared to the one on the GI-Paladin 400. This is why they have provided 2x self-adhesive strips to hold the backplate in its place. We have to deal with 11 components in total to mount the installation kit. Please refer to the user manual for installation steps.


The height of the cooler is 156mm. Keep this in mind while planning your build with respect to the PC Chassis.

20220522 185014 Copy

The front 120mm fan covers the XPG Lancer RGB 6000 DDR5 kit which stands at 44mm. This raises the overall height of the cooler to 160mm or so.

20220522 185027 Copy

As can be seen the tower without the fan has clearance for up to 44mm for the RAM height.

20220522 184957 Copy

The cooler does not block the first 16x PCIe slot on the GIGABYTE Z690 AERO-G.

20220522 184945 Copy

The rear end of the heatsink is not obstructed by the rear IO cover.

20220522 184936 Copy

The cooler has a good enough clearance for the top side of the motherboard as well.

Digital Lighting

The PCCOOLER PALADIN S9 features subtle A-RGB lighting on the fans and the top covers of the heatsink. We have tested the lighting using the RGB FUSION 2.0 app on the GIGABYTE Z690 AERO-G motherboard. The A-RGB lighting was responding to the changes flawlessly. Here are a few pictures:


The following test bench is used: –

  • Intel i7 12700k
  • XPG Lancer RGB 6000 32GB DDR5 kit
  • Nvidia GeForce GTX 1080 FE
  • Sabrent Rocket 4 Plus 2TB PCIe 4.0 NVMe SSD
  • be quiet! Straight Power 11 850W Platinum PSU
  • Thermaltake Core P6 TG Snow Edition in an open-frame layout

Here is the settings table for testing:

P-Cores Clock (MHz) 4800 All Cores
E-Cores Clock (MHz) 3800 All Cores
VCore (V) 1.140V [Overrides to 1.153V]
Turbo Boost Disabled
C-States Disabled
Speed Step Disabled
Thermal Paste Noctua NT-H1
Thermal Paste Application 4 small and 1 large dots on the IHS.
Test Run Time 30 minutes for XTU Stress Test

20 minutes CINEBENCH R23

Idling Time 10 minutes
Fan Speed 100% PWM Duty Cycle
Header CPU_Fan/CPU_Opt Headers
Software Intel XTU and CINEBENCH R23

This is our first regular cooler being tested on the newly established 12th gen hence there is no graph being plotted at the moment. The graph will be added once more coolers are tested.

The ambient temperature was in the range of 23.5° ~ 24.5°C. Let’s take a look at the results.

Load Idle Temperature Load Temperature
Intel XTU CPU Stress Test 24°C P-Cores Average: 69.5°C

E-Cores Average: 60.5°C

CINEBENCH R23 with AVX 24°C P-Cores Average: 77°C

E-Cores Average: 66°C


We are not measuring the noise level due to environmental noise that is beyond control. Both fans at full speed are not making loud noise and I was comfortable sitting close to the PC.


PCCOOLER has released a new cooler named PALADIN S9. This cooler is available in black and white color editions. This is a dual-tower configuration in 120mm size. The cooler is compatible with Intel Sockets LGA: 115x, 1200, 1700, 20xx, and AMD AM4 sockets. Each tower comprises 48 aluminum fins in a 43+5 configurator. The dimension of the cooler is 130×135.6x156mm where 156mm is the height of the cooler. Each fin has a 0.4mm thickness. PCCOOLER has stated that they are shipping their EX90 Thermal Paste with these coolers. The said thermal paste has a rating of 14.8W/m.k. Our sample was without any thermal paste hence we were unable to test this thermal paste.

This cooler is using 6x heat pipes having a thickness of 6mm each. These heat pipes are sintered powder coated and finished in a black color coating. In fact, the complete assembly is black color coated using a black electrophoresis (EP) process. They are in a U shape design making contact with the fin stack.

Each tower has a stepped design at the base of the heatsink. We have 43 fins on the main portion whereas the stepped area has 5 fins in recessed. This is done to make more room for the high-profile RAM. Both towers have stylish black color covers which are A-RGB backlit. The PCCOOLER branding lights up when powered on. The cooler has a pre-installed base plate which is a wise move. There are two spring-loaded screws on the base plate or crossbar. The base measures 38x44mm approximately.

This cooler comes with two 120mm A-RGB Auto RGB fans. The Auto RGB here means that the fans and the backlit top covers on the heatsink will light up in Rainbow mode in case we don’t connect the A-RGB LEDs to the power source. Each fan has semi-frosted 9x blades for even transfusion of light colors. These fans have a dimension of 120x120x25 and have a 105mm fan mounting spacing. These fans are rated for up to 1800 RPM ±10% speed with a maximum airflow rating of 73.6 CFM at the air pressure rating of 1.98 mmH₂O.

The A-RGB lighting is compatible with:

  • MSI MysticSync App
  • ASRock PolyChrome Sync

We have tested the A-RGB lighting using the RGB Fusion 2.0 on the GIGABYTE Z690 AERO-G motherboard and it was working flawlessly. The lighting is quite subtle and not overly done to my liking. I appreciate the PCCOOLER design team for using the standard 3-pin, 5V, A-RGB connector on the fan and the Y cable.

The installation of the cooler is convenient and involves only 11 mounting hardware items. The Intel backplate is required to be pasted on the backside of the motherboard which is something I personally don’t prefer. Other than that, the installation is not trivial and the user can set up the cooler in no time. PCCOOLER is using metal brackets though the backplate is not metallic. The towers provide RAM clearance of up to 44mm. The front fan, however, has to be slide up with a 44mm kit which increases the overall height of the cooler. The cooler has no clearance issue other than that. Its dimension of 130×135.6x156mm makes it a fit for the majority of the mid-tower cases. To err on the side of caution, do check the case clearance beforehand just in case.

The PCCOOLER PALADIN S9 has an MSRP of $66.99 which is a tad high priced than the EK6000 and EK6020 coolers. The later coolers are single tower configurations. The PCCOOLER is offering 3 years warranty on the PALADIN S9. We have tested the cooler on our new test platform based on Intel Alder Lake S sing i7 12700k. The cooler was able to handle the AVX load with mild overclocking on P-Cores and E-Cores quite well and did that with better acoustic performance from the fans.  The PALADIN S9 packs a good thermal performance as an average of all P-Cores temperature values was 77°C at 24°C ambient. Clearly, we have more thermal headroom for further overclocking. PCCOOLER means business with their PALADIN series coolers and S9 is no exception to that.  The Paladin S9 based on its features set and good performance comes recommended by us.

We are thankful to the PCCOOLER for the provision of the PALADIN S9 cooler for review.
