The latest PC case on our test bench is the King 65 Pro, a mid-tower model from Taiwanese manufacturer Montech PC. We’ve previously looked at the company’s Hyperflow AIO Liquid coolers and found them to offer top-end performance at budget prices.
The King 65 Pro is a successor to the previously released King 95 Pro. The chief difference between the two is that there’s less SATA storage supported (2+5) on the new model versus the larger Pro (5+8). Will the K65 Pro make our list of best PC cases? Let’s take a look at the specifications of the PC case straight from Montech, then we’ll go over the features and wrap up our review with thermal and acoustic benchmarks.

Features of Montech’s King 65 Pro Computer Case
*️⃣ Tinted tempered glass combined with diffused ARGB lighting
The case features black metal for the body of the unit, with darkly tinted tempered glass on the front and sides. When the ARGB is turned on, it delivers a sleek illuminated look that isn’t quite properly captured by my photos, despite my best efforts.
*️⃣ Build Quality
The overall build quality is sturdy and solid, with no apparent structural weaknesses.
*️⃣ Side view and customization options
The case features a relatively standard layout on the inside, with lots of room for big GPUs (up to 16.5 inches).
*️⃣ Radiator and fan support
At the top of the case, you can install up to a 360mm radiator for custom or AIO liquid cooling.
If you want to replace the side intake fans, up to a 240mm AIO is supported there, vertically.
*️⃣ IO Panel
The IO Panel is located on the front right side of the case. At the top are power and reset buttons, followed by audio and microphone jacks, two USB-A ports, and one USB-C port.
*️⃣ Rear side view and cable management features
The back of the King 65 Pro features pathways for cable routing and multiple strap points with pre-installed Montech-branded Velcro straps.
*️⃣ Storage support and unofficial extra fan support
There are multiple places to install storage on the back of the case. Above the power supply rests a drive bay that supports up to three drives.
Near the front of the case, behind the fans, is a panel that can house an additional two 2.5-inch drives. If you use both the drive bay and the panel, you can have up to five drives in total installed.
This panel features an adjustable hinge for easy opening. While not officially supported, it can also support an additional two fans for increased airflow – as demonstrated with an Akasa fan below.
*️⃣ Hardware ARGB and PWM fan hub
Pre-installed on the backside of the case is a hardware hub, supporting up to six PWM fans and six ARGB lighting connections. This is especially useful for folks who want to add extra fans to their system.
*️⃣ Front view
In a design that’s quite similar to Lian Li’s O11 line, the front of the Montech King 65 Pro ships with darkly tinted tempered glass next to a brushed metal bar that houses the front IO panel.
*️⃣ Rear view
*️⃣ Bottom
At the bottom of the case lives a giant dust filter and four rubber-bottomed feet to support the case and facilitate airflow. The dust filter pulls out from the back, though, which means if you put the case near a wall, you’ll have to move your PC every time you clean the filter.
Thermal Tests, Test Setup, and testing methodology
These thermal tests are presented to give you more information about the product’s performance but aren’t intended as the sole judgment of the chassis. The style, price, features, and noise levels of a case should also be considered – and we all have different preferences. What I might like in a case, you might not – and vice versa. That’s OK. My goal with these reviews is to give everyone, no matter their preferences, enough information to decide whether or not a product is right for them.
The measurements I’ve benchmarked this case against focus on:
- Maximum cooling performance on the CPU when fans are normalized to a moderately low noise level; the GPU is idle for this test. This primarily shows the efficiency of the fans included with a computer case.
- System fan noise levels
- Maximum cooling and thermal performance in a worst-case-scenario test that fully stresses both the GPU and CPU. We’ll cover the temperature of the motherboard VRMs, CPU, and GPU in separate charts.
- Comparing CPU and GPU temperatures in a workload that is similar in power consumption to Far Cry V. This stresses both the CPU (approximately 150W) and GPU (275W).

Noise Levels
The fans of the King 65 Pro reach up to 49.2 dBA at full speed. This is slightly louder than I prefer, but they’re PWM-controlled, so you can easily set them to run more quietly if you prefer.
Maximum Thermal Load – CPU Results
For this first test, I removed power limits from the Intel i9-14900K CPU and ran Cinebench R23 while also running Furmark 2 on the Radeon RX 7900 GRE GPU. This causes total system power consumption to reach around 600W.
This should be considered a “maximum performance” or “worst case” scenario.
During this test, where both the GPU and CPU are pumping heat into the case, the CPU consumed an average of 236.4 Watts. This isn’t exactly the best result, but keep in mind that the difference between 262W and 236W is only 11% in a theoretical worst-case scenario.
Maximum Thermal Load – VRM Results
Another way to judge this same scenario is by looking at the motherboard’s VRM temperatures. While the temperature of the CPU itself wasn’t impressive, the VRM temperatures were very good – though I have to wonder how much of that is due to the 11% lower CPU power consumption the CPU sustained.
Maximum Thermal Load – GPU Temperature Results
There’s not a big difference in the thermal performance of the GPU I’m using between cases. From best to worst there’s only a spread of 7.2 degrees C. I suspect that I would need a more power-hungry GPU to see a more significant thermal difference. In my tests running Furmark 2, the 7900 GRE GPU will use approximately 276W. However, in today’s market that is merely mid-range power consumption. Nvidia’s RTX 4090 will consume twice as much power in the same scenario. All that said, the Montech case delivered the worst GPU temperature result of all the competing cases I’ve tested here.
Maximum Thermal Load – Noise Normalized
For this next test, I’ve set the system fans to run at 40.3 dBA on cases with PWM control. I’ve also normalized the output of Akasa’s Soho H4 Plus, setting it to 76% – 40.9 dBA from one meter away.
You can consider this a measure of the case’s efficiency when set to low noise levels.
Our CPU cooler was able to cool approximately 248W during this test. While this is technically at the bottom of our chart, keep in mind this is a small 4.8% drop in maximum theoretical cooling performance when using a low-end cooler while running Cinebench R23’s multi-core benchmark. This is a worst-case scenario, and realistically most users won’t notice a difference.
Intense Gaming Thermal Load
The last test I’ve performed for this review is to test the cooling with a moderately intensive gaming workload. For this, I’ve set the Intel i9-14900K CPU’s power consumption to 150W while running a full load on a Radeon RX 7900GRE GPU, which consumes approximately 276W. This is similar to what I’ve experienced with these components when playing Ubisoft’s Far Cry V.
The i9-14900K reached 82C, and the ASRock Steel Legend 7900GRE reached 67C at the end of this test. While this isn’t bad per se, it is again at the bottom of the chart of cases I have thus far – trailing the best competitor’s results by 7-8 degrees C.
Conclusion
Montech’s King 65 Pro offers a sleek dark aesthetic with tinted tempered glass and diffused lighting. Its thermal performance isn’t great, but the case carries a relatively moderate price of $89 USD and has good build quality. If temperatures are more important to you than aesthetics, you may want to consider Montech’s 903 Max or another high-airflow case instead.
