Cougar Poseidon GT 360 Review: Great Performance, If You Can Find It

German company Cougar, founded in 2007, offers a range that includes many peripherals, from CPU coolers to keyboards to gaming chairs. While companies like Noctua are known for their “solid” brown colors, Cougar is known for having orange accents in many of its products, and in particular for its orange fans (although you won’t find any here).

We have Cougar’s Poseidon GT 360 on our test rig, an AIO liquid cooler featuring a 360mm radiator. Is the GT 360 able to tame Intel’s Core i9-12900K and earn a spot on our best cpu coolers listing? We’ll have to test it to find out, but here are the specs first, straight from Cougar. The Poseidon GT 630 is currently available in Canada for $149.99. It is also available in Australia and Taiwan and should be available in other regions soon.

Installing Cougar’s Poseidon GT 360 was pretty straightforward. To get started, you’ll first want to attach the heatsink to your case. Next, press the backplate against the motherboard and secure it using spacers and silicone pads.

Cougar does not pre-install thermal paste, but does include a small tube of thermal paste with the unit. After applying the thermal paste, press the CPU block against the standoffs, then use the included thumbscrews to secure it.

What is different from other coolers?

CPU block with ARGB lighting and rotating infinity mirror

The CPU block supports ARGB lighting and an “Infinity Mirror” with Cougar’s logo that can be adjusted to any position you desire. This means you can install the pump in any rotation without the logo being in an odd orientation.

Hardware ARGB controller

Some coolers on the market require the use of proprietary software in order to change light settings. Cougar’s Poseidon doesn’t have software, which means you’ll usually have to use your motherboard’s BIOS commands to change lighting options or download a tool such as OpenRGB Where SignalRGB in order to make adjustments. However, Cougar includes a SATA-powered hardware ARGB controller that lets you change ARGB settings, literally with the click of a button.

Cougar MHP 120 Fans

A liquid cooler is not limited to the radiator and the pump. The included fans have a significant impact on cooling and performance. The Poseidon GT 360 includes three Cougar MHP 120 fans, which have a solid black color and high static pressure. These fans do not support ARGB lighting, a choice that seemed odd to us, given that the CPU block has RGB lighting.

Model MHP 120
Dimensions 120 x 120 x 25mm
Fan speed 600-2000RPM ±200RPM
Air flow 82.48 CFM
air pressure 4.24mmH2O
Noise level Up to 34.5dB(A)
Lighting None

Radiator with “UTTERRIGHT” fin design

Many radiators use fins with curved ends, but Cougar’s Poseidon AIOs do not. Instead, Cougar uses “UTTERRIGHT” fins, which have a right angle shape. Cougar states that this design allows for greater heat transfer surface area and increased cooling efficiency compared to more common fin designs.

Test Setup

I’ll be testing Cougar’s Poseidon GT 360 with Intel’s Core i9-12900K, paired with an MSI Z690 A PRO DDR4 motherboard and Be Quiet’s Silent Base 802 shell. Due to the increased thermal density of the Intel 7 manufacturing process, as well as changes to the core and component layout, Alder Lake processors are more difficult to cool than previous generation processors in the most heat-intensive workloads.

This means that the coolers that kept previous generation products like the i9-10900K nice and cool sometimes have trouble keeping Intel’s i9-12900K under Tj max, the maximum temperature before the CPU starts to heat up. strangle. Many coolers I tested failed to keep the i9-12900K under max TJ when power limits are removed in workloads like Cinebench and OCCT. We’ll soon find out how it compares to the latest AMD Ryzen 7000 processorswhich also have higher TDPs than previous generation chips.

Please note that many factors other than the CPU cooler can influence your cooling performance. A system’s motherboard can particularly influence this, as there are motherboards on the market with CPU sockets that do not meet Intel’s specifications, which can cause warping or poor contact with the CPU. The case you use will also influence the cooling results.

Keeping Alder Lake cooling requirements in mind, I will rate CPU coolers in 3 different tiers.

Level 1 : These coolers are able to keep the i9-12900K below max TJ under most loads, with no power caps applied. I expect only the best liquid coolers to meet this standard.

Level 2: These coolers are capable of keeping the i9-12900K below the max TJ threshold with 200W CPU power limits enforced. I expect most liquid coolers and the best air coolers to meet this standard.

Level 3: These coolers are capable of keeping the i9-12900K under max TJ with 140W CPU power limits enforced.

Testing methodology

To test the limits of a cooler’s heat dissipation capabilities, I run two main stress tests: Cinebench and OCCT, each for 10 minutes. While that might be a short amount of time, it’s enough to push most coolers – both air and liquid – to their limits.

When stress testing in Cinebench, I run both with power limits removed and with a CPU power limit of 200W. Silent Base 802 computer from Be Quiet, only the best coolers can pass Cinebench tests when power limits are removed.

I don’t test OCCT without power limits because attempting to do so causes the CPU package power consumption to increase to over 270W and instant throttling with even the best AIO coolers. Instead, I test at 200W to give the coolers a chance to pass. I’ve also included 140W results to give comparable data to a processor that doesn’t use as much power, like AMD’s Ryzen 5800x or Intel’s i5-12600K.
