For those with high CPU temps, have you checked with top or htop to see what's running and using a lot of CPU? My temps on AX88U are roughly the same at idle on beta3 as 384.18, around 55c.
 
RT-AC86U running beta 3...for no apparent reason the router restarted on its own this morning. Installed beta 3 over beta 2. Beta 2 installed over beta 1. When beta 1 was installed did a full clear/reset then reformatted jffs partition as I was running the alphas. No extra software installed. No VPNs installed. No USB attached. Very vanilla setup. Router was just sitting idle...nothing logged into it and no power failure either. Here is a portion of the system log from yesterday (Dec 29) at the end of installing beta 3 and then the reset at 8:42AM on Dec 30. Looks like the router restarted when my apple watch tried to log into the router. I just had my apple watch connect to the router and it connected fine. Changed watch to different SSID and the watch and router disassociated perfectly. No idea what caused the restart...

Restarts like these are hard to spot but has anyone else observed restarts in the logs?

Yowsa. I installed Beta 3 over Beta 2 on my 86U. The temperatures on Beta 2 were consistently around 80C. The temperature of Beta 3 is varying between 90 at boot and 94/95C after 3 hours.

Edit: 95C at the 6 hour mark.
Edit2: Looking at htop I saw a fair amount of CPU usage by pixelserv, so I uninstalled diversion standard. After another hour, still 95C, so that's not it.
Interesting on the pwr settings:
Power Management Configuration
Functional Block Status
CPU Wait DISABLED
Ethernet Auto Power Down ENABLED
Energy Efficient Ethernet DISABLED
Switch Deep Green Mode ENABLED (status deactivated)

I upgraded from beta 2 to beta 3 as well.

I did not notice a significant change in CPU temperature. Maybe it depends on the router model.

Ambient temperature here is around 19 C. I have my router placed on a USB powered fan, this brings the temperature down (about 10-12 C).

Mine also experienced an increase in temperature. AC-86U
76 C and now 92C at idle. Room temp 21. What's going to be next summer at 30C and above! :oops:

Geesh huge bump! Is it possible that it is currently working on adjustiung itself or something? Are CPUs loaded? Have you checked what TOP command shows? Maybe in a few hours it will settle down...
 
Regarding temperature. Ambient temperature around my AC-86U is 25C. The CPU of the 86U is at 76C running beta 3 basically at idle.
 
At least on my RT-AC86U the CPU wait power saving feature has been disabled and results in higher temperature. You can check the status with the command pwr show from the command line.

Same here as well. Don't remember that setting so I assume something else triggered it as disabled.
 
well i got the rt5300 fixed and it is running great on beta3 transfer speeds are now 30 MBPS between computers 60 feet apart with 4 0r 5 walls , used to get a best of 20 to 26 MBPS . for some reason it is working better than ever guess it needed that factory reset
 
I haven't spent much time looking at my router's temperature, but I do glance at it once in awhile. This seems normal to me. Room temperature between 65 and 67F.

I checked mine out of curiosity, output is below. Barely any load on the CPU at this time...

Temps: 2.4 GHz: 46°C - 5 GHz: 52°C - CPU: 78°C

Those are my temps to with an RT-AC88U, no appreciable CPU load. From everything I've read here and elsewhere, these temperatures are well within spec.

Yikes, thanks for the pointer.

I was getting the following in my logs:
Dec 31 09:33:32 kernel: thermal cooling_device1: turn off CPU#1
Dec 31 09:33:32 kernel: IRQ6 no longer affine to CPU1
Dec 31 09:33:32 kernel: CPU1: shutdown
Dec 31 09:34:02 kernel: thermal cooling_device1: turn on CPU#1
Dec 31 09:34:02 kernel: CPU1: Booted secondary processor

The CPU was pegged on 99 degrees.

Running the command "pwr config --wait on" has re-enabled the CPU wait state.

Temps are slowly dropping towards 90 degrees now.

So far, I believe that the bump in CPU temperature only seems to be happening on RT-AC86U routers. Everyone else can relax and stop reporting .

Would guess that command could be run in a startup script on an AC86U pending a fix? Keep us posted on your Temps, please.

It seems to have settled right on 90-91 for now. Temps are 30 degrees ambient here, and from memory, I am sure I usually see 85-88 temps on my CPU.
