Ambient Temp Without Thermometer?

post #1 of 8
Thread Starter 
Is it possible to determine the ambient temperature of my room based off of system component temps? I have a well ventilated full tower case, with one HDD in the front of the case and an SSD on the back of the motherboard tray. With everything at idle, the SSD is showing 27°C and the HDD is showing 30°C, the motherboard is at 28°C and the CPU is at 30°C.

If these readings are fairly accurate, I would guesstimate the ambient to be about 25°C, what do you think?

What's the thermostat in your house say?

Calculating ambient from component temps probably isn't very accurate because whether they are idle or not, they are still producing heat.

What does it feel like to you? Does it feel comfortable? Cool? Warm? What? What does the thermostat say? How does the air at the thermostat feel in comparison to your room? Is that air warmer or colder than your room? Or is it the same?

 

Really, if you're getting temps like that, then I would guess that your room temp is around 70°F.

 

If you have a couple of bucks, then you can get a simple desktop thermometer from a dollar store or some other store like that. Or, you can find one at Target, or a hardware store.

The thermostat is in the hallway on the other side of the apartment, and it's set at about 74°F I think(difficult to read). But my room is slightly warmer than the rest of the apartment, I'd say ~76°C.

EDIT: It just occurred to me that my space heater has a thermostat function, and it showed 73°F. I think that is the final answer lol.

Is your space heater on the floor? Is your rig on the floor too? The air temperature near the floor is surprisingly quite different from the air temperature in the middle between the floor and the ceiling, which is about where your upper body and head is.

Yes, the space heater is on the floor, but my computer is on my desk, about 3 feet higher than the space heater. I do notice a difference in temperature from the floor to my head level, but it's not dramatic.

Then that air temperature probably is about 75 or 76 like you're guessing. Damn. Not bad! You don't need a thermometer. lol

Haha thanks, I live in this room so it's naturally easy for me to guess. I'll just consider the ambient to be 77°F(25°C), when I'm calculating the cooling delta after I put my loop together, can't wait! Just need that CPU block to hit the market now, already got everything else ready and planned out.
