It’s a new 2bay desktop TS-264. QNAP’s recommended operating temp is 0-40°C (32-104°F).

Am I taking a risk running close to 40°C; it could get that high if furnace runs for a long time. Are the temp swings a problem (it’s generally cooler than the rest of the house down there when furnace is off).

Any advice, tips, experiences please?
