Cooling a 5800x

I currently have a cryorig A80, and it is just pegged at 90C all the time in games, idles at around 55C, spikes up to 80s just on the desktop for long periods (basically if it isn't completely idle).

So either my A80 has finally kicked the bucket (I do get warm air from the side the hoses enter, but not hot and the far side is usually cool) or it just isn't up to it. Repasting did nothing at all. This is with a mild undervolt btw.

So while I'm not majorly concerned about these temps, the noise is a lot because the fans are just at full tilt all the time and the A80 doesn't seem to allow for separate pump and fan control (there's a harness off the pump that splits to take both fans). Even so, at 100% fans and pump it still can't hack it.

So I'm considering a 360 rad AIO. Am I on the wrong track?

I should add I have 4 120mm fans on the case as well as the two 140mm fans exhausting through the rad. So case temps should be fine (air out the case is barely warm)
 
Your AIO is not working as intended. You should easily be able to cool a 5800x with that sort of AIO. 5800x only uses 120w when running a full core load so imo you have a bad contact or faulty AIO, my guess is the pump has bitten the dust so you are getting inadequate to no water flow.

Edit - Run a full core load with blender and then obviously check temps , will be 90C no doubt , but then also check your cpu Mhz whilst it is hitting 90C. If you are getting 4.4GHz at 90C then you are not throttling that much but if you are getting significantly below that speed then there is a major cooling problem. Do not run this program for long , just a quick test.

5800X runs really hot because of the way it's designed, all 8 cores are on the same CCX, so that's a lot of heat in one spot, so even high end coolers struggles a bit, especially at default settings.

What are your OC/PBO settings? When I had a 5800X, at default settings, it would hit 85-90c, so to keep it in check, I had to adjust PBO settings with these values - PPT - 125, TDC - 75, EDC - 110, curve optimizer of negative 15 (try -10 if you're getting crashes), which gave me max temp of 75c (with Scythe Fuma 2) for essentially no performance loss.

Your idle temp doesn't seem right though, mine sat around 35c depending on the weather + background tasks.

Mine is currently idle at 27c and just did a benchmark and maxed out at 66c

I do have a Arctic Liquid Freezer ll with fans running at ~ 50% to keep it quiet.

I have set PPT 125 TDC 84 EDC 125 with curve optimiser -25 all core with a 0mhz core offset.

Only have 3 X 140mm case fans, 2 intake and 1 exhaust also running ~ 50%.

All core it sits at around 3.9GHZ and 90C, and that is from a cold boot. I reckon it'd get worse if I let it run for a bit to warm up the coolant. In fact, it's down to 3.8 just in the time it took to type this.
 
So I checked, and my A80 was bought 6 years ago, so it is possible the fins are a bit gunked up by now and slowing down the flow rate. Picking up an arctic 360mm AIO to see how that fares. At the very least I will get some more RGB for my case :rolleyes:
 
The Arctic Freezer II aio are very good. I have a 360 in a second PC. Rads are slightly thicker than other brands and the tubes are quite long as well so be sure it will fit into your case.

For reference. My 5800x is under an open loop, so very good cooling, and running the cpuz stress test the cpu is 4.6ghz all cores and 75 C and thats with the fans on medium revs , not trying to max out the cooling and just letting you know what sort of numbers you should achieve with a fully functional aio

Thanks that's encouraging. The fans going full tilt is driving me a bit batty
 
Arctic Freezer II performance is great. Only issue would be the thicker rad that may not fit where the others would. Corsair 5000D, for example, depending on your motherboard.
The pump will run at 100% when PWM set to 40% or more. Not an issue, as you won’t hear it. More likely to notice the Tiny fan that helps cooling the VRM, but honestly only once I got one that O could hear. Nothing crazy, just because I’m really pick about noise. Installed many and only once one was noticeable. Fans, they may hum at 1000-1200rpm, but honestly, you should be fine setting your fans at 40-5”% and that’s it.
Last few P12 that I used didn’t have as much humming as they used to. May be luck, don’t know. Had to increase 1 by 1% until the humming started. And not all fans.
Most Aserek based AIOs will present high pitch noise, not much can be done about that.
For the AIOs I’ve tried, the Arctic was the quietest, and best performance. EK is very close. Pump gets noticeable quicker. No chance to keep it at 100% like the Arctic will and don't get annoyed by the noise. But no need to have it at more than 50%.
ASU’s, every time I’ve tried, couldn’t stand the noise from the pump. Like the LL fans, the ML included with the AIO perform well but get very noisy.
BeQuiet was disappointing, again pump noise.
Basically the Arctic will give you top performance at decent price and very low noise.
 
Aios are consumable items, they dont last and fail all the time with either pump issues or coolant blockages.
Grab another aio for another limited lifespan cooling solution or get air cooler for life?

I mean, mine lasted 6 years, which for the convenience factor when working in my case is pretty good

Exactly.
The inconvenience would be more concerning if you use quite a lot of RGB fans and all the extra wiring, then trying to cable manage everything, but the Arctic offers 6 years warranty, top performance and low noise, and a single PEM and a Single A-RGB or RGB connection depending on which one you choose.
Impossible to be any easier to install.
With Aircoolers, what most forgot to mention is RAM clearance, case clearance, performance affected by GPU nearby, access to unlock GPU from PCI-E slot, etc.
There’s pros and cons for each side.
AIOs tend to show more issues because there’s more mechanical parts involved. But opt for a robust no frills one and you should be fine.
 
Yeah, and while it isn't my top priority, I'm not gonna lie that I prefer the aesthetic as well. I went with the straight RGB version because I prefer a static colour and having more money to being able to do fancy things
