Which desktop computer generates the most heat?

Recommended Posts

Posted · Original PosterOP

Hi there, I want to find a desktop or anything, that generates or blows a lot of heat from its systems and it can be used as a space heater over the winter. Right now I have a dell optiplex 620, equipped with an ancient pentium d 915 cpu, and it actually generates a considerable amount of heat to warm my legs. Do you guys know any better performing PC, AMD or Intel, cpubenchmark 2000>, that generates an absolutely stunning amount of heat that warms your legs up in cold days?

FX 9590 + R9 295x2 Crossfire, or GTX 480 should work just fine!

A spaceheater would be a more appropriate (functional/effecient) solution to this..

My rig will kick out ~315W of heat with GPU and CPU at full load(Ryzen 5 1600, GTX 780).

 

R9 Fury Xs ran pretty hot, as did the R9 295X2, pretty much any FX 8/9xxx CPU. GTX 4xx/5xx cards and higher end 6/7xx cards as well(my 780 pulls 250W).

This video should help as a guide if you're serious about this:

But a conventional space heater would be a better option.

While a space heater would be quieter, If you have a bunch of old computers lying around there is no reason why you couldn't altcoin mine, or fold on them and use them as space heaters.

Literally anything under full load

What you mostly need is a large heat sink and plenty of airflow to prevent it from dying.

 

Just buy a real space heater though


I edit my posts a lot, Twitter is @LordStreetguru just don't ask PC questions there mostly...

What is your budget/country for your new PC?

 

what monitor resolution/refresh rate?

 

What games or other software do you need to run?

That would be the AMD FX 9xxx series space heaters, and if your mining the gpu's or asics.

i don't think that's exactly how that works... i use a dual-xeon server as my main pc, and the air coming out of it is quite cold, not hot enough to warm my feet anyway. even though it consumes about 200 watts at idle, and a lot more when under load. 

 

it does heat my room though. if i leave it on for hours it gets a few degrees hotter.

Gotta go threadripper if you want to warm your toes. In reality, any cpu/gpu combo will work as long as you have slightly sub par cooling solutions for them so they run over 85 C.

A space heater would be cheaper but it's the same efficiency when it comes to power consumed turning into heat. https://www.pugetsystems.com/labs/articles/Gaming-PC-vs-Space-Heater-Efficiency-511/

Mining seems to be the way to go if you want to use a PC as a heater.

Sounds like your PC isn't exhausting to your feet in that case.

Am I too late to make an original AMD joke?

 

old hardware, heavy work load, PC in a position to move as much air around the area you want heated. 

 

For the serious heater experience I had an old friend who's family had 4/5 PC running in a small room 24/7.  Their power bill was something stupid like $2800 a quarter, but that room was toasty 24/7.

@mr moose Every time I see your avatar I think of how much it looks like Jayztwocents. Where is it actually from? ?

@everyone else, you can't unsee it now. You're welcome.

AMD FX-9590 is one of the best CPU's for heating and for GPU's I'd recommend 4-way SLI GTX 480 or 580. If you want more heat, then overclock the CPU and GPU's.

 

You might need a pretty good PSU and CPU cooler.

Space heaters work great as...space heaters.

You must need a PC for a project or something to suggest this? I mean you can just go and buy a heater for a fraction of the cost, so there has to be more to the story than this.

9th gen intel chips might work too as a space heater.

 

In fact an i-9 9900k and acrossfire VEGA setup is probably about the warmest you can get, at least till software comes along to fully use the RTX series ray tracing, i suspect thats going to see a massive jump in thermals when it hits.

 

To be fair it depends on room size too. My I5-4690k + GTX 970 have kept my room toasty for years without issue, but this is a tiny room, under 100ft^2, (9m^2 if you prefer imperial).

The highest tdp processors are amd 2nd gen threadripper.  I can't seem to find any info about tdp for gpu's but my logic would dictate that the more cuda cores the more heating potential.  So for gpu i'd look at older titans.

All electrical energy a computer uses eventually ends up as heat.

Basically, power draw = heat.

I run the FX-9590 liquid cooled (triple radiator double width) in my PC with an RX 580, and when I am stress testing the ambient temperature in the room can shift from around 68 to 80+ within an hour (my rig is overclocked and pulls around 520 watts when at full synthetic load). You have to be able to extract (hence the liquid cooling mention) the heat from the CPU or GPU to get good heat dissipation throughout the room. Granted, my room is not small, its kinda medium. Used to be a dining room before we put a wall up, my 3 windows are covered by insulated blackout curtains so there is very little loss of heat.
