Personally....If I had a unit running consistently over 65C...I'd add a fan.
Most Military spec testing is done at several temperatures...two being 60C and 90C. Getting near 75C+ on commercial (non-military) device...I'd be adding a fan for sure.
redhawk _________________ The only stupid question....is the unasked one.
Stumbled on this topic and created an account just for the same specific issue, CPU Temp. from a BCM4708, using a D-Link DIR-868L, tried putting a fan under it, 220v AC Fan usually used for Data Cabinets, temps are the ff.:
CPU - 60°C
Wireless Temp.
2.4G - 42°C
5G - 42°C
Tried creating airways for it(putting a bunch of holes under it for the air to move in), anyways can't seem to lower it even further other than opening the RF Shield of the CPU and replacing thermal pads.
So is this normal temp. for the CPU or should I do some more drastic measures to fix the temp.?

I've notice over the years that consumer routers are not well designed to take advantage of passive cooling. Yes air can get in from the bottom but it can seldom flow out the top, thus creating a hot surface to reflect back heat to the board. A second problem is that the main board sits horizontal reducing airflow over the heat sinks and chips.
I have found that my netgear r7000 processor is 4C cooler just by raising the left side about an inch. This allows hot air to flow up the board from the right side toward the left side and out the vent on the left side. My linksys routers have also been more stable and cooler by placing a spacer under the front allowing heat to flow out the front rather than gathering under the dome in the top center which otherwise get nice and warm.
my R6300v2 (standing router, airflow should be better!) idles at 76C and room temperature is 24-28C, its been like this for three years now no issues. when Air-condition is on and cool air hits the router, router temperature becomes 65C.
RT-AC56U:
WASCPU ~85 °C / WL0 ~50 °C / WL1 ~58 °C for years in new condition so it's normal
Yesterday I had to disassemble the router because It's got dropped then I became aware of that my router is touching 98 °C when idling. I found out that one of the heatsink's screw has been broken after the drop.
I fixed that but this time I used a higher quality ThermalGrizzly Thermal Pad. Now the temperatures are around CPU 79.4 °C / WL0 52.1 °C / WL1 55.8 °C it's pretty good, nothing to worry about. Also it's summer now so the avg outside temperatere is way higher in that room when my router is.
I won't use any aircoolers because:
1.: The router is pretty okay with these temperatures because they are designed to handle these temps
2.: The dust. I am not touching the routers unless I really have to, so the router is in it's place for years w/out any interactions, if I use an aircooler then it'll definitely become really dusty.
I also had a very old TP-Link router and it was working for 5 years straight with a flashed DD-WRT (only restarted because power outlets or smth like that). It's pretty yellowed old now, but it's working right now in my friend's house as I gave it to him.
So anyway these routers are pretty good with high temperatures.
Hi all.
My D-Link DIR-868L has been running nice and well for years and years. Today I happened to look at the status page and saw the following:
...which kinda shocked me a bit, and then a quick Google search sent me to this thread. I guess a temperature like this should be a problem, right? The router in question is in a little cabinet together with some servers, NAS etc, but it's not particularly warm in there.
Should I dismantle the router and check if cpu cooler is badly fitted? Anything else I should look at? Or is this perfectly fine (keeping in mind that I actually haven't had any problem with it)?

Well it is idling at 100 °C so I guess it's not normal. Yes, you should disassemble it and see if the sink is well-fitted or not. If the screws are okay then I guess you could try to replace the thermal pad.
Hi, I'm having exactly the same problem.
Did you fix it?
Everything working good here, but with around 100c temperature.
Thanks

Nope. I bought a tube of cooling paste but I actually never came around of doing anything with it. And the router is still working fine, although these temperatures worry me a bit...
