Temperature Question: Would it be a bad idea to place my new NAS in the HVAC room in the basement? When the furnace is on the room climbs to 30-35°C (86°F).
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).
If your ambient temperature is that close to your operating temperature, you're going to have to pass a hilarious amount of air across the machine to keep it within range. So don't do it unless you're going to blow fans directly at it that are controlled by internal thermostat or are always moving air fast enough.
Not that this is hard. One 6"inline duct blower could do this if you cowl it right.
Provide it with conditioned air for intake, but in the cooling season route the exhaust to your furnace's air return, to contribute toward heating the house.
I'd consider insulating the ductwork and doing air sealing if it gets that hot, as it means lot of your heat is not making it where it should so your hvac is probably running more than it needs to.
