5800X3D Running Hot on AIO and Custom Cooling – Need Help!

[pestermess]

I’ve had my Ryzen 7 5800X3D for a while, and I’m shocked at how poorly my custom water cooling and EK AIO are handling temperatures. Idle temps are around 40-45°C, and under 70-90% load, it can reach 90°C. It’s even hit 100°C on a hot summer day with the AC at 25%.

 

I’ve tried the curve optimizer and underclocking through the desktop app, but I still don’t understand why it runs so hot. Gaming pushes it to 50-70°C, but even opening a browser tab makes the temp rise quickly. I love the chip, but I’m frustrated—could I have a defective one?

It runs hot because if the X3D. You can set arbitrary temp limit in the BIOS at the cost of mainly multi-threaded performance.

The 5800X3D is known to run hot. Sounds like you have average temps. Depends on the size of custom loop and what synthetic stress tests you're running if there is any cause for concern, but just from my experience with the CPU I'd say no. If you want to lower the temps and haven't already you can disable PBO in bios.

Just luck of the draw. Not all X3D run warm, just like not all run cool. There are quite a few people who say X3D is easy to cool and quite a few who don’t.

I haven't used an AMD in forever, so I want to ask why you're underclocking instead of undervolting. 

[freeagent]

Just wanted to say, you don't need to touch vcore at all, just the curve.. in a negative fashion.

 

This is mine, just sitting here, and after playing Forza Motorsport and MSFS for awhile.

 

 

Just luck of the draw. They sip power because they are power and clock limited. Some silicon is good, some not so good. This was an expensive CPU when it came out here in Canuckistan.

They don't seem out of the ordinary to me. If it has the power headroom with stability and it hasn't breached your thermal target it will run up until it does. They hit thermal limit before power limit. Hence why curve optimizer works but you could target a lower temp.

 

90 is pretty normal these days. And a sudden spike if your pump isn't running fast is normal as long as it is a spike and not maintained 

 

What was it running before your custom loop?

 

We are assuming contact, pump, and paste are all done right of course

90 is hot as balls, you might just be used to people posting terrible temps with terrible cooling and terrible cases.

 

You can max PPT, TDC, but EDC is another story.. good luck maxing that on AM4 X3D.

 

Take a look at my HWiNFO

 

 

That is literally the absolute max that the socket will give to this CPU while in PBO.

Mine is 5700X3D. Running Stress Test and it reached 90 degrees. 

 

I use NZXT Kraken X62 + Arctic MX-6, so cooling is not an issue here.

 

The problem with 3D stack is it's inefficient to cool. When both CPU die and 3D Cache operating simultaneously at full power, Heat can only escape from 1 direction and have to go though one another. This cause CPU to overheat and start thermal throttling. 

 

Anyway. It never reach 90 degrees under normal usage.

Full Load Temp is around 65-70 degrees.

Half Load Temp is around 50-55 degrees.

Idle Temp is around 35-40 degrees.

 

If it goes 90 degrees under normal usage, something is wrong with the Bios. i.e. PBO setting?

Luck of the draw. I can almost guarantee that all the good silicon is going to server lines, and new models on AM5. AM4 is literally getting all the garbage silicon now. My guess is its probably why all of these newer AM4 parts run like ass.

Something is wrong there, I've been bench testing my 5700X3D with a Wraith Prism cooler with MX-4 paste and it'll hold 4050mhz for an entire Cinebench 2024 run (multiple minutes) and hang around 75C on the hottest parts of the CPU. I can only get it hotter with Prime95 small FFT which is the absolute worst case scenario for power and heat, it'll drift upwards to 85C. I have a light undervolt but I upped the PBO Scalar to a manual 3X to keep the all core boost clock pegged at maximum, 1X or 2X was dropping clocks under all core loads. I'm running similar core volts around 1.2. Maybe I got an especially good one, my sample size is only one, but your screen shot seems not great there.

I'd check your paste application and mounting pressure just to make sure that's all seated and spread well, that AIO should have no problem cooling 120W. I'd go grab some better screenshots and data but my board is apart waiting on a replacement chipset fan from China.

yep  but " AIO" is not a standard unit of measure   

 

same with "custom" 

[freeagent]

People are under the impression that the "very best" cores go to X3D on AM4, but I am not one of those people who believe that. I think some of the worst silicon AMD made has gone to X3D on AM4.

 

With an air cooler, not even an AIO I was destroying custom loop guys with my X3D in terms of temps. My X3D is old enough where all AMD had was good silicon, for the most part. Or back again to location on the wafer where your CPU originates. The closest to the center gets the best, towards the edge is the worst.

 

I wonder why there are not many EK AIO in the wild

"custom loop" is not a standard unit of messure   but u have some OC /tweeking work on ur hands

But you didn't say measurement, just that something was missing and then you put in photos of AIOs!

If u can tell me how big his AIO is    without this info   we cant do anything rly

That is very true..

 

I dunno.. stuff you see at OCN, expensive stuff

Well then, ask for that instead of a cryptic message.
