Using PC as Space Heater

[Raytsou]

I don't even know if this belongs here or off topic, but here goes. So I have an AMD FX-6300, which has a TDP of 95W. If I were to run a cpu stress test, how many degrees will the cpu heat up my room per second? My room dimensions are 2.5m x 3.2m x 4.5m. 
I'm legit cold right now and the radiator isn't doing very well.

Just use a blanket...

If you want heat, you'll be better off using your GPU, typically they draw more power than CPU, unless you've got a really low-end GPU. To calculate the heat really you'll need a power meter to see how much power the PC is pulling at the wall. Every watt the PC draws is converted to heat eventually, so a PC using 500 W is exactly as efficient as a 500 W electric space heater at heating, but we would need to know the actual power draw.

my AMD card keeps my room pretty toasty once i start playing games..

Not enough to make a difference that  you would appreciate.

If you can get me a few numbers I can figure it out

starting room temp
end room temp
room volume
time spent benchmarking

average CPU temperature

If you really want a space heater, get a bit coin miner.  Since heat is a desired product, it will make bitcoins and heat up your room at the expense of power! 

[Enderman]

the rate of temperature increase is not a linear relation, it depends on the temperature delta between the CPU and the ambient temp

True, but what's the fun in that?

According to PCPartpicker, my max TDP is 339W. But I doubt I'd achieve that ideal situation, so maybe do for 250W?

I have no OC because my pc crashed yesterday and rebooted telling me OC unstable, though I can get it up to 4.0 ghz real quick. For cooling, I have a Hyper 212 Plus, 2 120mm and 2 140mm.

I use my E5-2680 and r9 290x to fold, and unless I keep my window open, the room gets very warm.

Are you serious? LOL

 

I laughed out loud.

[Sakkura]

An electric space heater usually draws a couple thousand watts. A single-GPU rig just doesn't really matter for heat. If you get like an R9 295X2 or other multi-GPU setup running continuously, then it could begin to have a noticeable impact.

starting room temp

end room temp

room volume

average CPU temperature

Why do you need end room temp? I'm looking for end room temp.

Room temp now is about 19C

Room volume would be 36m3

Maybe 30minute benchmark?

Average cpu temp would be 45C because my cooler causes it to stay at 45C. But that isn't accurate because that's not how much the cpu is. But we'll use 100W as baseline (How does the conversion work..??)

[Dabombinable]

Straight up, my Xeon X5450 at 4.4GHz is more of a space heater than that FX6300. And it actually made my room warmer in winter when running F@H with my GTX970+GTX650ti (I think my CX850M wanted to kill itself).

This might not be practical, but I'm bored and curious.

Here ya go, buy two of these bad boys. You'll be able to heat an entire house.

okay one sec

[Raytsou]

okay one sec

Thanks. Can you show your work? And while you're at it, if I run a gpu stress test at the same time, I can get the thermal output to be ~250W. Can I get calculations for those, too?

Nah...

This isn't actually a difficult thing to look up.  Calculating the heat output of servers is used to caclulate the air conditioning needed for server rooms all the time, you can go and look up the various charts for this.

 

​Also, if you pay for electricity, it's a huge waste.  PC's are designed to produce as little heat as they can, relatively speaking, they aren't designed to efficiently produce heat relative to how much power they consume.

Well, yea, it would be costly. But I'm just curious on how much my pc is heating up my room.

It's no more wasteful than electric space heaters; PCs are precisely as efficient at converting electricity to heat.

So after doing all my math and such I was able to calculate that with your PC putting off about 450,000j of energy per hour (about what you'd expect with a 250w draw from the wall) I was able to calculate the you could expect a 14.629°c rise in temperature in your 36 cubic meter room, however you have to take into account any potential thermal leaking through windows, door frames, walls, etc. So realistically you'd see a 10°c rise in temperature that seems rapid initially however eventually slows down and stops.

Also keep in mind that this would not be linear as your room would eventually reach thermal equilibrium. Here is the math / equations-
