Assuming you can install two GPUs using 600W, that's basically running a hair dryer in your desktop since most of the energy is converted to heat.

- oatmeal_croc 5y agoWell, all the energy is eventually converted to heat.

- ksec 5y agoThis got me thinking. ( I must be missing something or having wrong assumption in my high overview of the issue. ) Do Crypto People use their GPU generated heat as heater assuming they lives in a place that requires heating anyway? Doesn't that equate to free money assuming they could actually mine crypto?
- saberdancer 5y agoYes. That's one of the benefits. Some people use electric heating even without crypto so using GPUs to mine crypto to get the same effect is a no brainer. Problem is that during the summer you have to get rid of the excess heat, so you need air conditioning or perhaps open air cooling. Not gonna lie, I've used my GPU to heat up my small room before.
- denton-scratch 5y ago> so you need air conditioning or perhaps open air cooling. Or icebergs - Reyjavik is a popular place to build data-centres, so I have heard. They also have good geothermal in those parts.
- reportgunner 5y agoIm no expert but coupled with solar panels you get more power during summer to run the AC
- adrianN 5y agoIt's not a "no brainer" if you include the cost of the GPUs. You need to do at least a little math to figure out whether it's actually cheaper that a simple resistive heater (or a heatpump).
- belval 5y agoPretty sure that he was implying that if you already have a GPU then you should mine during the winter instead of using conventional heating. That's how I read it at least.
- i21QMgplhRJs2OL 5y agoCheck out this video on using the heat from computing beneficially. https://www.youtube.com/watch?v=hNytmvltsWk https://www.youtube.com/watch?v=hNytmvltsWk
- faeyanpiraat 5y agoHeating with a Heat pump or Gas is significantly cheaper, so if you look at the big picture, it’s not “free money”.
- nomel 5y agoOpen air heat pumps have a lower limit for their operating temperature, so can't be used efficiently in cold climates (around < 25F), since they start to use more energy than they provide as heat. Geothermal heat pumps solve this, but cost more. Gas is somewhere around half the cost of electricity. Back in the day, you would still profit with a GPU.
- someonewhocar3s 5y agoI assume people will not miss the market for PCI-E hair dryers which is just now opening up.
- BeFlatXIII 5y agoIt helps save on the winter heating bill if you live in Wisconsin.
- jakogut 5y agoMost? Where does the rest go?
- denton-scratch 5y agoAll of the energy is converted to heat. Some energy from your rig is emitted as light; but that's your monitor, and your monitor has its own power supply (which means that 600W is an underestimate).
- worrycue 5y agoThe RTX 3080 already uses 320W (peak?). By next GPU generation who knows. Good lord, just 2 generation back GPUs like the 1070Ti consumed 180W. Even if you add a CPU (of that era) like the i7-7700 with it 65W draw, that just 245W. Now a video card alone can draw more power.
- lostmsu 5y agoI have a 2xRTX 3090 rig under desk. At close to full GPU load the temperature on the desk is about 3F higher than in the room.
- noobermin 5y agoWhy is this being downvoted? If you have a kilowatt (I wanted to type that out instead of write KW to emphasize it) coming out of the wall that energy has to go somewhere. Literally warm your room during winter and turn down your heater.
- worrycue 5y agoAnd make your AC work even harder during summer or if you live in a tropical/desert/…etc. climate.
- Arrath 5y agoI've idly been considering ducting my desktop's exhaust outside like a clothes dryer vent. My previous computer didn't run very hot at all so the exhaust fan on the top blew onto the underside of my desk and then at me, it was actually uncomfortably cold in the winter. This new one is something else, though.
