      In my experience, how close to the ground your device is typically dictates how much dust it will acquire. My firewall is about 2' off the floor and it only has a fine almost non-existent layer of dust, while my desktop tower is right next to it, but only 3"-4" off the ground, and it has dust bunnies that require a Holy Hand Grenade to exorcise.

        Ok so to the naysayers:
        1. I am quoting core temperatures
        2. We are talking a 35w processor which has a max temp of 105C before throttling.
        3. Why would I bother with prime? This chip isn't going to see load like that in its current purpose, it will spike but it won't be continuous heavy load.

          Where are you getting your MAX ok operating temperature from?

          You don't have to purposely stress test the system for it to encounter a race condition all on its on.

            Sorry - 100C

            Coretemp - TJ Max

              I think I trust the intel chip site more…

              40C won't break it but if you are really seeing 60C, I don't think thats great.

                  Urm, it is cooler than with the stock intel cooler…

                    Well - So long as you like it and it works.  Thats all that matters.

                      35w TDP is low, I agree, but you're talking about 35w in dead air if you have zero fans whatsoever.  The i7 3630qm in my laptop is only a little higher at 45w, but as soon as windows update kicks the cpu usage up to 10% the fan has to kick on to keep it from going over 70C (this thing weighs 10 pounds just from the copper in the heatpipes).  I'm not trying to be a debbie downer, I just think you should be aware of what the temperatures can get up to in that configuration should something happen.  Say a bug is introduced in a package, or you decide to download a new one that looks fun without realizing how much CPU it uses.  Suddenly your CPU usage is spiking and that thing is sitting at 85C regularly and dipping higher.  I'd just tend to error on the side of caution, but I'm also the person with 2 very quiet CPU fans on my heatsink in a push/pull just incase one of them fails (which has happened, bearings don't last forever).  Passive cooling can be neat, I agree, but is there a particular reason you'd prefer no internal fan whatsoever?  Dust sucks, I agree with that, but dust filters are cheap and there are thousands of silent fans out there.

                      In the end, it's your equipment, and I'm just offering an opinion!

                      Intel site list's TCASE, TCASE is from the IHS and can't be 100% accurately measured after the product leaves the factory.  Using the Tjunction and core temps is the way to go.  OP looks like he's actually running the core temp program which is my personal preference as well.  Are you running pfsense through hyper-v OP?

                        add a casefan if you do not want to add a case and cpu fan. blow it out with compressed air once in awhile
