Normal Operating Temp NG-4200

[TechGuyTnE]

I have just purchased a NG4200. While I'm just doing basic firewall and router stuff with it so far, it seems like a pretty polished and capable box.

So far, using this device has been like a breath of fresh air compared to what I have been using.

My question is, in the System Information panel of the Dashboard, it says that the unit normally operates at around 52 Deg C to 54 Deg C (approx. 118 Deg F).

Is this a reasonable temperature for this device to be operating at? While the graph doesn't have any range markings, this temperature is over 50% of max according to the slider bar. Maybe the graph auto-ranges?

This just seems kind of warm to me for a device that has only been running at around 4% to 7% CPU Utilization so far.

Forgive me if this question seems a little ignorant. It's my first Netgate hardware and my first experience with pfSense. I'm hoping to push this box a bit harder once I get more familiar with using its potential.

I don't want it to overheat, and I'd really (really!) would rather not have to provide some form of auxiliary active cooling.

Thanks for any insight that this forum can provide.

What's the ambient temperature? How is it mounted?

Since its entirely passively cooled it will be affected by both those things significantly.

Check the logging in Status > Monitoring:

That said 52°C is not a value that would concern me. The max junction temperature for the C1110 is 100°C.

Thank you for response.

The device is sitting on my desktop. All of the case vents are unobstructed. The ambient temperature of the room has been right around the 75F (25C) range, give or take.

The fact that it's passively cooled was one of the reasons that I bought it.

Thanks again for your reply. Super helpful to know where to find a breakout of the core temps and the specs on the chip itself.

@TechGuyTnE My new 4200 is on my desk in my "home lab", nothing sitting on top of it, nothing sitting below. Room temp is 76-77 degrees F. The 4200 is running at 63F, cpu at 8%. I thought mine was high also. I just have the "stock" packages running with the addition of haproxy.

63°F is only 17°C which seems unlikely. And also very cool! Do you mean 63°C?

If so where are you seeing that?

[alleykat]

@stephenw10 Yes, I'm sorry, 63C, lol.

[stephenw10]

Hmm, that does seem warm. Where are you seeing that value? On the core temps directly?

@stephenw10 This is where I'm seeing the temp.

[stephenw10]

Hmm, odd. You may need to reset the RRD data.

What does the thermal sensors widget show?

[alleykat]

@stephenw10 I'm now thinking I made it switch from my 2100 to the 4200 on May 29. Maybe the config from the 2100 still needs more changes. I made the interface assignments with a text editor to the config xml and loaded it on the 4200. So far so good, first issue I've ran into. Do you happen to know, was there other areas in the 2100 config that needed to be changed?

[stephenw10]

You may not have Speedshift enabled in Sys > Adv > Misc since the 2100 doesn't have that. That will bring down CPU temps.

[alleykat]

@stephenw10 Speedshift is already active (checked). Control level Core. Power Preference, slider in the middle.

How do you reset RRD?

[alleykat]

@TechGuyTnE Sorry TechGuy, I didn't mean to "highjack" yout thread...

In Status > Monitoring > Settings (Advanced).

The default value for SpeedShift is 80.
