As a content creator who runs Blender renders and edits 4K video, I needed a case that could handle a high-performance GPU without overheating. I installed an RTX 4070 in the NR200 and ran a 10-minute render test. The GPU temperature stayed under 70°C, and the case remained quiet throughout. Real-World Testing Scenario I used the following components: - Motherboard: ASUS TUF B760M-ITX - CPU: Intel Core i7-13700K - GPU: NVIDIA GeForce RTX 4070 (320mm length) - Cooler: Noctua NH-L9i (92mm height) - PSU: Corsair RM750e SFX (750W) The GPU fits with 15mm of clearance on both sides and 20mm at the rear. The case’s front panel has a 120mm intake fan, and the top panel has a 120mm exhaust fan. The PSU is mounted at the top, creating a positive pressure system that pulls air through the front and expels it through the top. Thermal Performance Data <style> .table-container { width: 100%; overflow-x: auto; -webkit-overflow-scrolling: touch; margin: 16px 0; } .spec-table { border-collapse: collapse; width: 100%; min-width: 400px; margin: 0; } .spec-table th, .spec-table td { border: 1px solid #ccc; padding: 12px 10px; text-align: left; -webkit-text-size-adjust: 100%; text-size-adjust: 100%; } .spec-table th { background-color: #f9f9f9; font-weight: bold; white-space: nowrap; } @media (max-width: 768px) { .spec-table th, .spec-table td { font-size: 15px; line-height: 1.4; padding: 14px 12px; } } </style> <div class="table-container"> <table class="spec-table"> <thead> <tr> <th>Component</th> <th>Temperature (Idle)</th> <th>Temperature (Load)</th> <th>Thermal Throttling?</th> </tr> </thead> <tbody> <tr> <td>GPU (RTX 4070)</td> <td>36°C</td> <td>69°C</td> <td>No</td> </tr> <tr> <td>CPU (i7-13700K)</td> <td>39°C</td> <td>73°C</td> <td>No</td> </tr> <tr> <td>Case Ambient</td> <td>24°C</td> <td>28°C</td> <td>N/A</td> </tr> </tbody> </table> </div> The case maintains stable temperatures even under sustained load. The top exhaust fan runs at 1,200 RPM during peak load, but the noise remains below 30 dB—quiet enough for a home office. Why It Works The NR200’s design prioritizes airflow over aesthetics. The front panel has a mesh grille that allows unrestricted air intake. The top panel has a large exhaust opening with a 120mm fan. The PSU is mounted at the top, which prevents hot air from recirculating into the GPU zone. Limitations and Workarounds - GPU Length: Max 320mm. The RTX 4070 is 318mm, so it fits perfectly. - GPU Height: Max 135mm. The NH-L9i is 92mm, so there’s ample clearance. - Fan Placement: The top fan is critical. I recommend using a 120mm PWM fan for optimal performance.
