Board temp of 135C is fine Dave?

Or am I reading his post wrong and it is 135F which is perfectly fine?

OK after I reformatted his post I see now, yes those temps are fine as Dave said.

Why do people not check their formatting

Since this topic is about temp and fan cooling here is my daily temp graphs from my Netonix that its placed in a sealed IP65 metal box.
Since during midday hours fan speed is constant above 9300RPM is there any issue with MTF of the fan? Should i open breath holes so the air to circulate (chimney effect)?

Your board temps look OK.

Air flow can not hurt but the switch is not in any distress according to your telemetry.

If they can run fine without the fan, how about some better fan control modes in firmware?
e.g.:

Low noise = fan doesn't come on until much later.
Optimal Cooing = current fan mode
Better Cooling = fan comes on earlier for use in enclosures or high ambient.

The WS-12-250-AC would make a great SOHO switch, being able to power IP phones & cameras at 48v and Unifi APs at 24v, if that fan wasn't so darn noisy!
We put a couple out for evaluation in this use-case but ended up deploying another make as the clients at the pilot sites complained about the fan noise...

Hi guys,

At those temperatures will this unit be okay? I have a similar reading...

Re: fan speed

Thermal
Board Temp 42 C
CPU Temp 66 C
PHY Temp (Ports 1-12) 72 C
PHY Temp (Ports 13-24) 44 C

Cooling
Fan 1 Speed 10000 RPM 2220 RPM
Fan 2 Speed 10000 RPM 2640 RPM
Fan 3 Speed 10000 RPM 2430 RPM

So, if there any way to INCREASE the fan speed and any clues why one set of ports running SO much hotter than the other. We had this unit lock up today and simply rebooting it seemed to fix it, but the temperatures and the differences concern me. It is about an hour away and would prefer not to have to run out there again.
