Passive cooling my i5
-
it is sitting between 50-60C and running well.
No fans in the case, and it works!
Just curious, what happens if you turn on prime95 or something that pushes it?
-
i would have some type of exhaust fan in there

Why bother with a fan? The TCASE is 66.35°C
He has 6 whole degrees left over before he hits thermal max… ;D
Its gooooood....

While I agree with the sentiment that no fans is probably not good, I'd imagine he's reading the core temp which would correlate with the TJUNCTION/TJMAX limit. TJUNCTION is core limit, TCASE is the IHS limit, and the IHS is usually a bit cooler than the cores themselves. That being said, once he gets an actual load on the processor I think it's going to start cooking without a fan on the heatsink.

I tend to agree - Is there a fan that only spins up at all if set to a predetermined temp automatically?
Mine are always turning either slow or fast but never sitting still. Seems its possible since my laptops don't spin up unless they get hot.

In other forums, you'll sometimes read someone asking why their computer seemingly runs fine, but once they load their video game of choice, the FPS is like 10. Then they'll mention later that the he at sink was not attached correctly and there was a gap between.
Modern CPUs are quite good at self throttling, although high temps for long periods of time will shorten their life.
I had a GPU that ran at 108c during the summer and a much cooler 105c during the winter. I used that GPU for 5 years before I got enough money to upgrade it and the case. That fan was LOOOUUUDDDD. I could have hooked up passive water cooling and kept it at a freezing 100c. Replacing the water would have been annoying.

I have an old amd desktop running for my personal pfsense. It uses 45w I think and the fan is slow and the case fan is slow…
At first this concerned me, but I have the side pulled off every 6 months or so and no dust accumulates in this thing.
It just keeps working and the specs are crap.
-
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.

Without pics it didn't happen!
;D ;)

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

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

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
