It's crazy, right? 
ESP8266/32 are soaring in popularity.
I'm not saying I would really want to put an Arduino into production, but they are great for testing things at work. We use them on special projects.

I can knock a board out so quickly, and pcbs from china are so cheap, I don't half-step with things like arduinos and breadboarding. Also, I like coding at the register level. But I've been doing this my whole life. For a hobbyist, I can see the allure of arduinos and related firmware libraries. Now, the raspberry pi comes with so much crazy capability, I can see why folks use those.

While replacing one of the drives a week or two ago, I noticed the processor and liquid cooler temps were quite high. So this week I opened up my computer case and blew the dust out of everywhere. I think the processor temps went down 10°C LOL. One of the fans had unplugged itself somehow from the mobo. I went into the BIOS and played around with the fan speed curves and the temp sensors they respond too, and got this machine fairly quiet.
Also, I played with the air flow in and out of the case. Previously, the liquid cooler fans on the radiator were blowing OUT of the case, I changed that and I believe it made a big diff. Here's the air flow now. You can see the liquid cooler heat exchanger displaying the temperature in the middle. I built this machine during the covid years and I think the 3-fan version of the cooler wasn't available, which is why there are only 2 at the top

I know this is Win11 thread, but Imma just drop this here
Pulling AIO-heated air into the case seems like Opposite World tech to me 
I feel this in my soul

Yessir. I got started with WordPerfect, and it had a feature called RevealCodes with which you could see all the formatting codes (in brackets). Was really easy to just delete the code, or at least you could see what was going on there. Word is a nightmare in this respect. Freaking tabs, tables, indents, all nuts.
But y'all HAD to have the WYSIWYG. I'm looking at you Apple.

OTOH, if you want efficient heat exchange in the radiator, do you run hot air through it?Pulling AIO-heated air into the case seems like Opposite World tech to me
Anyway, empirical data suggests this is better.

I'm not a gamer either (I want to be though, but life). I built it mostly because I like to build cool stuff, and also to do video editing of 4k content (which is quite processor and GPU intensive). But mostly, I just like building gadgets.

The more I think about this, the more I agree. I'll try to do a controlled test and compare temps and see. I'll have to set the fans to a fixed speed in order to remove variables.Pulling AIO-heated air into the case seems like Opposite World tech to me

If you don't want to be tempted to build a badass PC, don't watch this.
I'm a fan of net positive pressure in my computer cases so the air filters do their job. But I assume no one else in the universe will clean filters.
Re the radiator discharging into the case, I guess it depends on your bottleneck. You're helping your CPU at the expense of your GPU and all other hardware in the case (mostly RAM, VRMs, drives). If you're CPU-limited (maybe compilers?) then it might be worth it. But in the abstract, heat-goes-out is the sound default. I'd even consider the _insane_ idea of adding an inlet fan behind the CPU to get more balanced airflow.

all I can say about fans is buy the best, most are cheap and break down after a year, they also pull in dust so clean often

All I can say about fans is when the heck did it become necessary to do more than fan?
Why do I have to feel like I am at a planetarium Pink Floyd laser light show?
And stay off my lawn!

For what it's worth, I've had a few AIOs now (I seem to have bad luck with them lasting) and I've tried airflow both ways, and haven't noticed a substantial difference personally. I do have air flow "out" on mine now, because I'm more worried about cooling the GPU during gaming.
My CPU is currently running about 40, and I set my fans up in the BIOS to run at the absolute lowest speed the firmware allows, unless temps get up to 55? or so. My thought process is fans bring in dust, so I don't want mine running anymore than required, until I start a game. My PC is basically dead quiet, but when I fire up a game the fans RAGE.
Nobody keeps a separate air filter next to their machine?
If you aren't going to liquid cool, that's the only way to go.

This is why I still buy the ugly brown noctuas.
Fans should be neither seen nor heard. You can always tell a Milford fan.

Power tripper.
My daily driver (when I'm not mostly using smartphone) circa 2013 i5 4th gen.
I have several similar, including a couple used for dedicated NVR for camera systems. They are great general purpose computers that can be had dirt cheap (no, I did not buy these new) and run Win 11 just fine with the necessary installation tweaks to work around TPM and processor series.
That said, I do have an i7 HP Z-Book laptop picked up for pennies on the dollar also set up with Win 11.
Still though, most of my "computing" is via smartphone, older one too, Galaxy S9. LOL.
I bought a lovely Dell Latitude for cheap at office depot. What are your sources for cheap older systems?
CL or Marketplace, usually. Like anything some folks are high on their prices but then comes along someone with what I presume is a business and or school off-lease deal where they have a stack of 'em they are selling off.

My XPS 17 9700 I bought in 2020 is getting a bit long in the tooth. I do some medium to light gaming, mostly with friends but also just got into Starfield. The MaxQ RTX 2060 just doesn't hold its own these days, and I had this brilliant idea to get a board from a 9730, which nets me a RTX 4070, upgrades the CPU from a 10750H to a 13700H, DDR5 and a faster m.2 slot, because the body style is the same.
Welp, here I am, after spending about $700 on a board (includes CPU and GPU for $450), RAM, and a bottom plate, vapor chamber cooler, and the keyboard/trackpad/trim board... and the screen isn't compatible. After all my research, turns out that these boards were mated to a QHD+ screen, not a FHD+ screen. So I just had to plop down $200 for a screen. The only remaining HW from the original PC will be the sound board, wifi antennas, battery, fans and HDs. Oh, and some screws. Still cheaper than a new one, but probably not a whole lot cheaper than a used one. Oh well.

I bought a 34" wide monitor this weekend, and was pleased to see it connect and "work" on the first try. Windows / the video card figured it out and all was fine. My old Radeon 570 gets to stay in use a while longer I guess.
No gaming though, just happy it could do the resolution (3440 x 1440, I think).

The card I have right now is running 4 monitors (3 of them on my desk are 3840x2160. The 4th is less - it's on a workbench behind me. The card doesn't hardly get warm driving all these displays. Pretty amazing I'd say. The only thing I've used that gets the card firing on all cylinders is Microsoft Flight sim, which can use multiple panels. Haven't fired that up in a while, I might check it soon.
Tomorrow I am installing a new liquid chiller. Then I'll do some stress testing

I have a 34, and it works great. Tough to share the whole monitor on a Zoom.

But undeniably enjoyable doing so in order to watch the inevitable scrolltasticness that ensues on everyone else’s part!

Interesting choice in lighting. Kind of a Borg alcove vibe. Neat.
Surprised that card can support all those large format monitors. How much vram does it have?
Cheers!

Yeah, but does it have a 28.8 BPS modem, active matrix and RISC architecture?
that was such a goofy movie

I Play MSFS2020 in VR, and my GPU usage never gets above 80% or so. My card is a 4060. I get 30fps or so, still a lot more fun than using my 2k monitor though. I'm hoping 2024 will be an improvement. I do IFR flights, mostly 172 glass cockpit.

Which goggles?
Oculus Quest 2, I got them refurbed before the demand spiked a few years ago for $250. I love them, I play games (PC games) on them, I work in them (using Immersed) and I watch movies with my Uncle who lives in another state, using BigPicture.
GPU memory is the big constraint with gaming in VR, I really wish my card had 16 gb, or even 12.
And to make this relatable to Windows 11, Windows Mixed Reality is no longer supported, which sucks. I'm not sure what a good alternative is, but it looks like MS is going to blow a huge lead on this VR stuff, reminds me of the Windows phone.

I felt that binning Hololens is the biggest loss. Amazing product.

I was pining on the reverb g2 for a while. Then the quest (3 now). I'm a pleasure delayer. I really like to let these ideas simmer, the yearn and desire to slowly simmer, until I can't take it anymore. There is the pimax also, though reviews are mixed.
I'll probably ask santa for the quest 3 and see what happens (typically, regardless what's on my list, I get socks with toes, golf shirts, grilling equipment and a funny ham radio tshirt). Then I'll buy myself the goggles.

MS basically gives away the OS to non-commercial users. They are a biz, and focus on products that are profitable. I don't know what their profitability pie chart looks like, but people like me are likely an unnoticeable sliver. It's a wonder and a gift they keep the flight sim going.
