If you own a Samsung Neo QLED QN90B (2022 model), you are likely familiar with two things: the breathtaking peak brightness of its Mini-LED panel, and the endless debate surrounding Samsung’s firmware updates. Recently, one specific version has lit up Reddit, AVSForum, and Samsung Community boards: . Date: May 2026 Stay cool, QN90B owners

Search queries for “Samsung QN90B firmware 1710 hot” have spiked dramatically. Users are reporting that after updating to 1710, their TV chassis feels warmer to the touch, the fans (if present on One Connect Box models) spin louder, and in some cases, the panel triggers overheating protection shutdowns.

That last part is critical. Prior firmware (160x, 150x) aggressively dimmed the screen in bright HDR game scenes to keep the power supply and LEDs cool. Firmware 1710 loosens those restraints. The result: brighter, punchier HDR—but at the cost of higher thermal output. When users say the QN90B on firmware 1710 is “hot,” they are usually describing one or more of the following physical symptoms: A. Hot Chassis (Back Panel & Bezels) Multiple users have reported using infrared thermometers on the back of their 65” or 75” QN90B. After 2 hours of HDR gaming (e.g., Cyberpunk 2077 or God of War Ragnarök ), back panel temperatures hit 48-52°C (118-125°F) . Pre-1710, average temps were sub-45°C. B. Aggressive Fan Noise (One Connect Box) For QN90B models with the external One Connect box (e.g., 85” variant or specific regions), the internal cooling fan now ramps up to audible levels—resembling a low hum or whirring sound during dark scenes that suddenly transition to bright explosions. This never happened on firmware 1620. C. Thermal Shutdowns The most extreme reports (approximately 2% of users on AVSForum) describe the TV shutting down entirely with a pop-up message: “TV temperature is too high. The TV will turn off automatically to prevent damage.” This occurs after 3-4 hours of SDR sports viewing in warm ambient rooms (27°C+). D. Local Dimming Artifacts A curious side-effect of running hot: blooming becomes visible around bright objects in dark scenes. This suggests heat is affecting the response time of the Mini-LED driver ICs, causing them to bleed light. 3. Why Does Firmware 1710 Run Hotter? The Technical Theories Three leading theories explain the thermal increase: Theory 1: Overclocked Mini-LED Backlight The QN90B uses ~720-1,100 local dimming zones depending on size. Firmware 1710 appears to have raised the peak current to these LEDs from 1.8A to ~2.0A per zone. That’s an 11% increase in electrical power. Since LEDs are inefficient (roughly 60-70% efficient at high drive currents), the extra 0.2A translates directly into waste heat. Theory 2: Disabled Thermal Throttling in Game Mode Samsung received criticism that the QN90B dimmed too aggressively during long gaming sessions. In 1710, they appear to have raised the thermal throttling threshold from 65°C to 75°C on the LED driver board. This means the TV will let itself run hotter before reducing backlight brightness. Theory 3: Bugged Standby Power Management Some users report their TV remains warm even after being turned “off” (standby). A potential bug in 1710 fails to fully power down the One Connect Box’s main processor, leaving the SoC (system on a chip) running at 1.2GHz in standby. This adds 10-15W of constant heat. 4. Is It Dangerous? Thermal Limits & Safety Margins Let’s be clear: Electronics can run hot. Samsung designs the QN90B with a maximum rated ambient operating temperature of 40°C (104°F) and internal component temperatures up to 85°C (185°F) before failure.
