> I used and recommended ATI and INTEL for most of the people I could for a long time because of this. Same here but recently I somehow got a 3700X and there's no integrated GPU so I had to look for a GPU. I like my PC not just quiet but nearly silent, so a GPU with a fan was a big no-no. I couldn't find any single GPU able to drive 3840x1600 without a fan... Except for a NVidia one. Of course the proprietary Linux drivers are somehow buggy: the "sleep" doesn't work correctly, failing to reinitialize the correct video mode when waking up. It's always, always, always the same with NVidia GPUs on Linux. Thankfully I can switch to tty2, then back to graphical mode but I hate the inconvenience. I'm thinking about selling my 3700X and getting a 12th gen Intel with an integrated GPU (I don't game and really couldn't care less about fast GPUs).

Why not go for a 5700g? That would hopefully avoid you having to replace your motherboard.

It’s pretty damn stunning how quite an AIO 2x 140mm cooler can be. And graphics cards with those big triple fans are silent until needed. I’ve been through a couple 12th gens. I like them, but unless you need the machine updated right now, 13th gen is 6 months out.

  AIO performance on CPUs is largely limited by thermal transfer through the coldplate/IHS (Integrated Heat Spreader), not by radiator size. Basically the radiator is keeping the fluid very cool already, but heat can't move through the IHS quickly enough. So it takes a large improvement in fluid temperature to make a small improvement in die temperature - you are "pushing on a string" as the expression goes. Almost no AIOs have the fluid-temperature sensors that would allow you to measure this directly, so everyone uses the die sensors. Which, since they're behind the IHS, will be much higher than the fluid itself. The die temperature is also a measurement of interest too - I'm merely explaining why the number you're seeing in the die sensor isn't really the big picture of how good the the radiator is doing at cooling. The die is hot, but the fluid is cool. The AMD 295x2 is an extremely good example of this observation - this card had a single 120mm radiator, with one fan, and it could dissipate >500W of heat at ~60C die temperature. (not sure if this source says this directly but the non-OC power was ~430W average during gaming, and ~250W is not unreasonable for each 290X chip - actually they could go to 300W or higher if you really poured it on, but they also did generally show some significant power scaling with temperatures, so ~250W per chip/500W total is a reasonable estimate imo). https://www.techpowerup.com/review/amd-r9-295-x2/28.html https://www.techpowerup.com/review/amd-r9-295-x2/28.html You might say - but that's a dual-GPU card, with bare dies. And yes, that's my point, when the coldplate/IHS is no longer a bottleneck moving heat into the loop, a 120mm radiator is comfortably capable of dissipating 500W of power back out of the loop at extremely reasonable operating temperatures (60C die temperature). 60C is actually barely breaking a sweat, you could probably do 1000W through that 120mm if you didn't mind a die temperature in the 80-90C range. In CPU overclocking - your power limits/temps are almost entirely limited by how fast you can get that heat through the IHS. Reducing fluid temps (by increasing radiator size) is pushing on a string, it takes big gains in fluid temp to produce a small improvement in die temp. Incidentally, direct-die cooling is the last untapped frontier of gains for ambient (non-chilled) overclocking. Der8auer and IceManCooler.com both make "support brackets" that replace part of the ILM (integrated loading mechanism - the socket and its tensioning mechanism and attachment to the motherboard) that holds the processor. This is necessary since the IHS is actually part of the ILM - the ILM presses down on the sides of the IHS, so removing it would change the pressure, and the ILM needs to keep a specific level of pressure on the chip to make a good contact with the pins but but without damaging anything. But you can delid the processor (there are services that do this for soldered chips, I don't recommend doing it at home) and use one of those brackets with a "normal" waterblock/AIO (or even air-cooler), since the bracket is holding the chip in the pin-bed at the proper tension. Thermal density is going nowhere but up, Dennard scaling is over, so that is the only way to really improve thermals on <= 7nm-class nodes. Even AMD runs hot - they routinely run in the mid-80C range nowadays, even though they don't pull a lot of power - because of that thermal density, and every time they shrink it's going to get worse. The gains may be more worth it on Intel though - they show better scaling from power/voltage, TSMC nodes seem to pretty much top out at about 4 GHz and past there it gets exponentially worse for very little actual performance gain. 4.3, 4.4, sure, but they don't seem to do 5-5.3 GHz like Intel can on their Intel 7 given good temps and enough voltage. But yes, to go back to your original point, I really like my 3090 Kingpin as well. It runs extremely cool, I can keep the die at literally 30C with the fans cranked all the way up, and it'll keep the VRAM at under 70C (!). And since it is a 2-slot card it doesn't turn into a compatibility mess with motherboard pcie slots getting blocked and needing airspace/etc. I am 100% behind AIOs on the larger gpus that we are seeing lately, this is a better solution than triple-slot or 3.5 slot coolers, which are (imo) completely ridiculous.

If you want to stick with AMD and don't want to swap out the motherboard, then you'd probably just need to get an AMD CPU with on board graphics. The actual name of the CPU should help you find one that would work in that regard, for example, see this link which explains the naming suffixes: https://www.androidauthority.com/amd-cpu-guide-1222438/ https://www.androidauthority.com/amd-cpu-guide-1222438/ In particular: X - Higher clocked desktop processor (what you got) G - Has integrated AMD Radeon Vega Graphics (what you probably want) GE - Has integrated AMD Radeon Vega Graphics but lower TDP (what you might want in niche use cases) For example, some of my homelab servers use older AMD Athlon 200 GE as their CPUs, due to the fact that there are on board graphics and because the TDP is 35W, both saving electricity and also allowing me to use passive cooling (with just a large heatsink https://www.arctic.de/en/Alpine-AM4-Passive/ACALP00022A https://www.arctic.de/en/Alpine-AM4-Passive/ACALP00022A). For the Zen 2 series that your 3700X belongs to, you might want to look at this table: https://en.wikipedia.org/wiki/List_of_AMD_Ryzen_processors#APUs_3 https://en.wikipedia.org/wiki/List_of_AMD_Ryzen_processors#A... From what i can tell, the closest option performance wise to Ryzen 7 3700X but with on board graphics would be Ryzen 7 4700G.

  Side note: not that you said it yourself, but since you bought up the "E" SKUs, and it often comes up: in almost all situations, the "lower tier" CPUs can be replicated simply by taking the higher-tier CPU and setting a lower power limit. A 1800X with a 65W power limit is the same thing as a 1700, a 3400G with a 45W (?) power limit is the same thing as a 3400GE, etc. Since the "GE" chips and other niche SKUs (there is a 3700 non-X iirc, for example) are often OEM-only, and thus they only have a very limited availability, they will often command higher prices on ebay/etc than the "real" chip. In this case, there is no reason to seek out the "E" chip, with the possible exception of if it gets you the "pro" feature set and you happen to need one of the features (particularly for APUs since ECC is disabled on non-pro APUs). So if you see a 3400G for $200 and a 3400GE for $250 (made-up numbers) then don't buy the GE, buy the G and set the power limit yourself. Lower-end chips do not have better binning - actually the opposite, higher-end chips have better binning and will run at lower voltages for a given frequency than the lower-end chips will. The "higher leakage clocks better" thing is not really a factor that matters on ambient cooling, that is for XOC doing LN2 or LHe runs, but it has entered the public consciousness that "low-TDP chips are binned for efficiency". Not in the consumer market they're not - the exceptions being things like Fury Nano that explicitly are binned better, and for which you pay a premium price for that efficiency. But most low-end consumer processors are just... low-end. They're priced according to performance, not binning. You can see this in the SiliconLottery historically binning statistics: 1800X will categorically clock higher at any voltage than a 1700, a 3800X is categorically better at any voltage than a 3700X, etc - and that also means they will run a lower voltage at any target frequency. AMD bins straight-down in terms of chip quality: Epyc and TR get the best, then the high-end enthusiast chips, then the value enthusiast chips, then the efficiency parts at the bottom of the bins. The "E" parts are efficient because they have a low power limit set - not because they're binned better. Lots of chips can run fine at lower voltages, they just don't do the peak frequencies as well as the binned chips. A 1800X will still get you a bit lower voltage - but since the voltage/power curve is quadratic, the difference in power is compressed at lower frequencies/voltages. Also, at a low-enough frequency you will bump into the minimum voltage required, so that tends to compress things as well. So at 3 GHz, the impact on binning between a 1800X and a 1700 would be a lot smaller than, say, at 4 GHz. The 1800X can usually do that fairly easily in a later sample, but 4 GHz is pretty much always pushing the limits of safe voltage for a 1700, for example, so the 1700 gets crappier silicon because it clocks lower. https://siliconlottery.com/pages/statistics https://siliconlottery.com/pages/statistics https://www.reddit.com/r/Amd/comments/cll1r9/hardware_numb3rs_reports_his_findings_on_ryzen/ https://www.reddit.com/r/Amd/comments/cll1r9/hardware_numb3r... (the "one weird exception" is lower core-count chips. If you think of each core as a dice roll, this means that an 8-core chip has to roll perfectly 8 times, where a 6-core chip only has to roll perfectly 6 times. Since all-core OC is limited by the performance of the worst core, this means that for equal yields, there may be more lower-core-count chips with high all-core OCs. Many midrange parts do not actually have defective cores, they're locked out for market segmentation to avoid undercutting margins on the higher-end parts (which is why Phenoms and 7950s used to be unlockable, etc) and - while I'm not sure AMD has explicitly ever said it - it would also be sensible that when they are disabling cores on an 8-core to turn it into a 6-core they pick the best 6 cores, which would push silicon quality upwards too. A 1600X actually has silicon quality comparable to a 1800X according to SiliconLottery, for example, despite being a much higher-volume part. This "weird exception" also gets complicated with Zen2/Zen3 because AMD deliberately uses a low-quality die for the second CCD (3900X/3950X) since it will mostly be used under those lower-clocking all-core loads, and the impact of binning is compressed in those lower-clocking situations...)

I bought some midrange AMD graphics card a few years back, picked for idle wattage, linux support and quiet cooling. The card isn't silent, but it's quieter than the high end, low wattage PSU fan, which is needed to dissipate heat from everything else. Anyway, eliminating the video card fan would probably make my desktop louder, which was counterintuitive to me at the time. (The setup is extremely quiet, FWIW.)
