Oldish post but, I ended up getting a 5600x and motherboard combo for $200. Finished rebuilding last night and either I fucked up the cooler install or Ryzen runs a lot hotter than my old 8600K.

On idle, with auto settings, it fluctuates from 50 to 65c, where the fan is pretty loud. Under load it gets hotter and louder obviously.
Thinking about slapping a Noctua NH-D9L on there.

I got the same kind of deal last summer and I'm cooling it with an AIO watercooler. It idles at 40c and peaks at 70c, my old 4th gen i5 ran at about room idle temperature and would peak at 50c.
 
Eh, honestly don't think AIOs are worth it anymore. That $35 air cooler will most likely beat just about all of them. Water cooling in general isn't really great anymore unless you go super overkill so you can have a quiet pc while maintaining some really low liquid temp delta of like 5c over ambient.

I'd be fine with an AIO but my ancient case doesn't support anything bigger than a 140mm.

Nah, watercoolers need to be a bit bigger than that to make sense. Realistically you'll get equal or better cooling with a dual tower cooler, you would get a small watercooler either because your case doesn't have room for a big dual tower air cooler, or because you think it's cool.

Watercoolers are most efficient (in terms of heat dissipation per perceived noise level) when the temperature delta is high. I have a 280x60mm radiator on my 7950X+6900XT computer, and it's keeping them both well cooled. After being on 100% for a while the water will reach about 50 degrees, where the CPU is stable at 85 degrees during load, and the GPU around 70 degrees. Thanks to the high ΔT, my fans never need to go higher than about 40%, which is basically inaudible because Noctua. The fans can go up to 3000rpm so if I wanted to I could have a low Δ, but the noise becomes just unbearable. I agree that AIOs tend to be pretty mediocre, but now that CPUs and GPUs regularly drink 300+W, watercooling is more relevant than ever.

Eww. 50 degree liquid temp. I used to run an air-liquid delta of 4 degrees at only 50% fan load. I'm going to guess I run a lot more rad and fans than you. While the high delta means you transfer the heat to ambient air for efficiently, you're picking up heat from your components less efficiently than me having a liquid temp barely over 30c.

Ideally your liquid should never feel warm. Your rads and fans aren't cooling the parts, they're cooling the liquid.

Yeah, I have the one 280x60mm radiator, with two Noctua 140mm 3000rpm fans on it. I can run the fans at full blast and have a low ΔT (5-10 degrees) if I wanted to, but then I can hear the computer even through my closet door (it’s in a rack in a walk-in closet, so my office can be nice and quiet). I prefer having the water hot and the fans doing a good job removing heat even at low rpm. Even with the water at fifty degrees my CPU and GPU are well below the point where they throttle, so this provides adequate cooling. I would rather say that your obsession with keeping the water so cold is silly. You’re working the fans harder and probably not gaining anything unless your water blocks are particularly bad at transferring heat and you actually need the water so cold in order to keep the components cool.

But I'm not working the fans harder. I have more radiator eliminating heat and fans in push pull so they can individually work less hard. I'm not saying your way is wrong, it's just a pretty normal setup. Mine is in overkill territory because eh, I like the hobby and I like to keep components as cool as possible.

Pretty much if my case has room for a rad, I'm putting one there. To me a fan without a radiator is a waste. I'm running aquasuite as well so that I can maintain a custom fan curve depending on my ambient air to liquid temp delta.

Fair enough.

Yeah, I’m doing more or less the same. My case is a DIY thing, so it only has the two 140mm spots on the front. The only other fan is the 120mm one in my power supply. Air goes in through the radiator at the front, then passes over the passively cooled expansion cards, VRMs, and DIMMs, then exhausts through slots at the back and through the power supply. Works great. I have quick disconnects fitted on the back so I can plug in an external radiator, but in practice I’ve never needed it and it’s a hassle to purge the air from after a water change so I never use it. It’s a Mo-Ra 420, with that thing hooked up I probably have better ΔT than you do, it’s mental.

My motherboard has an external temperature header, so I plugged a thermistor in there which is screwed into the reservoir, so my fans are also controlled by the water temperature, just without any third party fan controllers since in my experience those require you to run garbage Windows-only software to do anything. My curves are essentially just 5% fans until the water is at 40 degrees, then ramp up to 40% until the water is at 50 degrees, then ramp up to 100% until the water is at 60 degrees. The water never goes over 50 degrees, not even on a summer day. With the external radiator it never goes over 30, not even for hours of benchmarking, since that’s when the (also controlled by water temperature) fans on that kick on at 5%.

Ah, that's pretty neat. I think I tried to do a small case loop once and gave up lol. I only roll with full/super towers now, so I have to fill them up with something and just happen to have a shit ton of fans lying around so I go nuts with em :D

I personally think noctua gear is overpriced. I've heard very, very good things about the peerless assassin 120 se which is only $35 on Amazon.

Competes quite well against the much more expensive D15. If you can fit it, they have the 7 pipe 140mm Frost Commander. The bigger and more overkill you go, the quieter you can run.

Speak of the devil. That cooler is gonna get some more attention now.

Is replacing the thermal paste on a 980 a bitch to do? Mine is starting to run hot and loud but I have way too many other things I'd rather spend money on than a 4070
 
I've been buying noctua fans for a long time. A good qualitative fan can stay with you long. I've experimented with many different brands of quiet PC fans and the problem always eventually came down to reliability and all kinds of strange bearing and resonance problems, either out of the box or with age. For all the years I bought noctua, I never had to retire one. I think the only fan manufacturer that's in tie with that particular performance metric in similar circumstances in my personal and completely anecdotal opinion is ebm papst, and I'm not sure the thread is familiar with them. It's also not about the noise in decibels alone, but also at what frequency. I bought one closed-loop AIO system out of curiosity a while ago (I used to have an incredibly complicated watercooling thing in the 00s) and found the high pitched whine it made more annoying than any fan. They're probably not all like that, but still. Also consider that the CPU fan in your computer case also has the job to get some moving air over other mainboard components in that area. If you do full watercooling, that might be missing depending on your cooling layout.

That would probably dox me, it's pretty unique.
It looks kind of like this, except in aluminium and without transparent side panels. Mine is shoddier construction too, it's a 3D printed frame with aluminium panels screwed on, not machine-cut steel or whatever that is. Mine is thiccer too, it holds a full ATX motherboard, 1kW SFX PSU, and 2x140mm fans plus 60mm thick radiator on the front. I also have the expansion cards side by side and in front of the motherboard, rather than behind it, since 140mm width gives me so much more room to work with.
 
Im not saying noctua doesn't make a good fan...but really. Come on. Some of the prices are retarded.

Also pro tip, as for longevity, you can keep cheap sleeve bearing fans going until the motor burns out (un likely) by taking the little retention clip off on the back of the fan shaft and putting a tiny bit of lube in there. Also can make them quieter.
