I love my gaming PC and 3d printer in the winter. Keeps my room toasty without me needing to run the heat much at all.
I hate those same things in the summer when I gotta have fans or AC just so I don’t melt lol
I turn off Folding@Home in the summer. Otherwise it’s on 24x7.
Wow f@h still kicking?
For everyone who isn’t trying to mine crypto, yeah.
Shit with my gf and I both gaming, sometimes we have to open a window in the winter
My server rack (in the cold garage) is now enclosed and the air filtered and piped into my grow tent which then regulates with cold air from the garage.
my grow tent
One of these days I also need to get around to starting my grow operation myself lol
I’m just kinda hunkering down with carts and waiting for MN to get dispensaries cause I’m lazy.
I was given some white widow clones and unfortunately could only keep them outdoors most of the time. Meant some generally early harvesting. I’m ready this year lol
That’s the dream right there.
I saw an interesting post that said
All electronics are 100% efficient in the winter
Now that we have reverse cycle AC (heat pumps), 100% is a low bar.
I know, but I didn’t wanna pollute my comment with a bunch of pedantry, despite my name. Also people living in apartments often don’t have access to heat pumps.
Love my heat pump, although its not AC. In the UK if you get ground/air to water the government give you £7.5k towards it. Air to air you get nothing. I suppose it is quieter, but for the 2/3 days in summer where it goes over 30°c having AC would be nice.
Back in high school, my buddy used to VNC into his Athlon 3200+ WinXP machine from school and start SuperPi calculating a million digits. Took 40minutes and got his room proper toasty by time he got home.
Electricity generated heat from your servers is incredibly inefficient compared to a heat pump.
Yes, but im already using the computer for other things and it would be more inefficient to double up on heating sources. I can confirm from personal expirence a PC in a small room can sufficently act as climate control.
Conversely it’s exactly as efficient as a resistive heater, which lots of people still use.
Thank you, this thought had occurred to me recently, and I was wondering if it was accurate.
This is true, but it’s shocking how few people have heat pumps, especially in colder climates.
Still, it’s also far less efficient than using a gas furnace (to the point that most people would actually burn more fossil fuels per Joule of heat from a resistive heater than from just burning the gas directly in a furnace).
Of course, if you’re doing something useful with that energy, using the waste heat is an extra benefit. Like using waste heat from a power plant for district heating.
“Incredibly inefficient” is a bit of an exaggeration, heat pumps typically run at an efficiency of about 2, occasionally 3. It’s better but not by orders of magnitude. Not gonna make much of a difference at 500 watts.
Not sure who’s down voting you. You’re right. There’s Heat pumps that can move 5x more heat than the energy they use. While a PC only gives you max 1:1
I interpreted the sentiment from OP that it was just reframing the reality in either case: the server is going to run, and it’s going to generate heat.
You can either frame that reality as “waste heat is being generated” or “my furnace doesn’t have to work as hard”
My home server was serving a dual purpose of keeping my closet full of 3d printer filament dry, but then the most recent TrueNAS Scale updates killed it by dropping my average CPU load from 10 to 4%.
Just open a few Chrome tabs. That’ll ramp the resource usage back up again.
Does ram really have that much thermal load/power draw? I don’t even account for it when I’m picking a power supply.
Just start a scan with a second anti-virus, they’ll fight it out and warm up your house quite nicely.
Or double dip and mine crypto when it’s cold out.
Even for a large amount of RAM that you’d find in a big server, it’s a few dozen watts at most. Here’s some charts showing the jump from DDR3 to DDR4 on a 16GB stick:

DDR5 dropped the voltage from 1.2V to 1.1V compared to DDR4, which tends to make it even more power efficient. Not quite as dramatic as DDR3 to 4, but in any case, it’s better still.
Those bastards.
I have actually gotten up to run benchmarks on my PC on particularly cold nights.
For the heat and electricity, it’s stunning how much compute I get from my somewhat modern gear vs. my 40U rack of 10-years ago.
My homelab is in the same space as my furnace so the ambient heat in that space is preheating my ducts. In the summer when the AC runs the cold air leaking into the space helps cool my homelab. In my garage office my desktop with 9 spinning drives and 3070 really keeps the space comfortable.
My server only draws like 300watts max, not a very good heater
Put a 4090 in there and pump those numbers up!
Sadly, for a few years now I’ve had TDP as one of the main criteria when buying parts for my machines, so there really isn’t enough waste heat from my machines to even just keep a room warm in Winter by playing heavy 3D games (the worst machine tops at around 180W with 3D and CPU heavy games - so basically the same heating as a really bright incandescent light bulb - whilst my home server uses about 20W at 100%)
On the other hand what I save in power consumption on my machines can be used on a dedicated heating solution that’s ON only when I need it rather than the whole year.
whilst my home server uses about 20W at 100%)
I’d love it if my equipment used so little, but I’d rather just pay a higher electric bill and be able to spin up whatever VM, container or DB I need for a project whenever I want without having to worry about resource usage
It’s really down to fitting the machine to one’s Requirements, present and forecasted ones.
So my home server is just a N100 Mini PC because it’s just a TV Media Box on my living room that doubles as home NAS and Torrent server with a dedicated VPN connection, for which an N100 with not especially large or fast memory and a decent-sized SSD, is more than powerful enough since the CPU heavy stuff - video decoding - is done in dedicated silicon inside the N100 so doesn’t really run on the CPU cores, whilst the other functionality is mainly bottlenecked by network speeds and my network is just Gigabit Ethernet.
If I expected heavier CPU loads I would have gone with a different CPU (plus associated elements such as motherboard and memory) whilst if I wanted to run the heavier AI stuff (such as image generation) it would’ve been a Desktop PC with a dedicated Graphics Card with lots of video memory.
As it is, my games PC doubles as Image generation machine and also works fine if I want play with VMs or Databases since that’s running Linux and is a lot more powerful in almost every way (curiously, not disk speed since it’s a bit old with upgraded parts, so it’s still using SATA and does not support M.2 disks on PCIe) than that Mini PC.
A machine on my living room is supposed to be quiet (so, no loud fans, hence low power consumption), so I was hardly going to over-dimension that living room TV Box / Server just to once in a while I could play with heavy stuff in it, given that I already have a different and much more powerful Linux machine at home that I can use for that, hence why I partitioned my needs this way and can have an always ON server that just tops at 20W (though generally it uses less than half that power).
PS: Also keep in mind that merely running a database isn’t by itself any kind of heavy load (even for heavy stuff like Oracle, much less mySQL or PostgresSQL), it’s what uses it that dictates the load, so even running a DB there is not an issue unless I’m doing tons of massive non-indexed queries against it (or huge dataset indexed ones, since non-indexed ones on huge datasets end up disk bound unless you have insane amounts of memory) or a similar pattern of usage.
I got a laptop for work, using it at home and I want to use my computer because if I just use my laptop its cold. When my pc runs the rooms is nice and toasty.
I have thought of this exact thing and thought I was the only one.
People used to mine Bitcointhis was. Only in winter.
