RB 5009 very hot when operating. Is this normal?

Can u check the temp showing on the Winbox-System-Health?
Mine is showing 40°C CPU temp with a 2x12cm usb fan under RB5009. (Normally should between 45-55°C)
I didn't use the 2.5Gb and SFP+ port.

For malaysia vlan ipv6,u can follow this guide- https://forum.lowyat.net/index.php?showtopi...&#entry63945436
If not strongly needed for ipv6,better do not enable ipv6 on unifi now.(maybe next year or next 2 year better,now still not stable enough to use)

Mikrotik IPv6 does not support fasttrack now,it will be implement in ROS7 future version but still does not have timeframe for it,so i think next year or next 2 year should be getting IPv6 fasttrack on mikrotik.

Currently,for RB5009 without ipv6 fasttrack,the cpu usage to use full 800mbps unifi is around 25-35% for 800mbps download,and around 6-12% for 200mbps upload.

My unifi dream machine 82 after reboot and reaching 85 after a while, still working fine without any external fan.. Dunno how correct this is.. But than can feel the heat when touching the router. Sell it already. Now waiting for RB5009.

I believe the 45-55 should be fine. They even tested the router for 60 ambient.. For me under 70 is still ok.. 80 maybe need cooling.

Noted, thanks for ur opinion

Disable anything you are not using can reduce the temperature up to 5degree on RB5009

I have to differ.
I don't recall having much issues with IPv6 on UniFi previously (since 5Mbps days, then 10Mbps)
No issues on TIME now too.

All my supported end devices have global IPv6 addresses, been running this for many years.

I usually use this to test IPv6 connectivity, unless there's any major issues, it's 10/10.
https://test-ipv6.com/

On Tests Run tab,
Test with IPv4 DNS record
ok (1.032s) using ipv4
Test with IPv6 DNS record
ok (0.820s) using ipv6
Test with Dual Stack DNS record
ok (0.813s) using ipv6
Test for Dual Stack DNS and large packet
ok (0.333s) using ipv6
Test IPv6 large packet
ok (2.110s) using ipv6
Test if your ISP's DNS server uses IPv6
ok (1.390s) using ipv6
Find IPv4 Service Provider
ok (1.091s) using ipv4 ASN 9930
Find IPv6 Service Provider
ok (0.929s) using ipv6 ASN 9930


Other IPv6 test sites,
https://ipv6-test.com/ <- I get 19/20 on this, because there's no reverse DNS record.

I actually don't install packages that i don't use. Less potential exploit surface too.

For those interested, i only run these.

advanced-tools
dhcp
ipv6
ntp
ppp
routing
security
system

I mean the unifi ipv6 routing is crap,for local service is okay,but for service that hosted outside of SG/MY then the routing might be quite not stable and causing the speed is lower than ipv4 to the same server(compare with ipv4/ipv6).

And of course even to Cloudflare, Unifi ipv4 and ipv6 also not having good everday,sometimes will reroute to HK area(TM- routing faults),so in this situation for important site,using self-choosing cloudflare ip entering to hosts file is better.

I personally don't really like UniFi running temperatures.
All the products I've encountered seems to be running their codes without "HLT (x86) opcode" (i know it's not a x86 inside, not sure what's the equivalent opcode).

mind to share guideline to enable ipv6 address for both public and private?

are unifi ipv6's down in certain area? everything bound but no ipv6 when doing test

btw, just upgrade to 7.2.3

no problem on my end-Johor.

Weird.. im at Gombak Setia. Before balik kampung everything ok. Turn On everything, all bound but no IPv6 while doing all test.

Heres some screenshot.. hope someone could help if my setup are wrong..

Did you set anything on the MTU? If not,set the MTU to 1480 on the ND.Im running the same hardware/software as yours,minus the only snapshot missing there is the neighbor discovery.

Previous working setup is no MTU setup. Already set to 1480 and 1280 and not working also. Asking TM (socmed/livechat) still no answer given.

Set the MTU to 1480 on ND and on the DHCP client,add default route option to NO.

Yes thank you so much! Solved! YOU the man. Thank you so much again.
