Main PC is 32-34*C for the package average, around 26*C minimum for the coolest cores individually, idling at 800MHz circa 2.5W. 14600KF slightly OC and undervolted, some DeepCool 50$ air cooler, PC located in the basement. Ambient temp is around 22*C right now but in summer humidity is high, the dehumidifier barely keeps up maintaining 60-65%, and variance in ambient temps in those conditions don't have any much impact on the CPU: the case design doesn't promote airflow when fully closed, which is how I like to use it because it's dead quiet, and I additionally set the quietest logical fan curves individually through extensive testing. In the winter it will drop around 17*C ambient and around 35-40% humidity level, becoming properly frisky. Then the ambient temperature impact turn things around, and I'll see about 25*C at idle on the package and about 20*C for the coolest cores, and then again regular variance in ambient temp won't affect those values in any much noticeable way once the colder weather takes hold. Even full 5*C variances in ambients, be it summer or winter, don't have much of any noticeable impact on the CPU in my settings. Only the larger seasonal shift does. Under stress, difference between winter and summer is about cut in half, like my present config will run around 95-96*C average in the summer and 91-92*C average in the winter for the CPU package - considering 100% load on all cores circa 185-190W package power. The "coolest" cores then also pretty much follow the same compression, running only about 2*C cooler than the whole package at best.
HTPC is also located in the basement, but in the finished division, open space, only a couple windows, none exposed to the sun very much. Keeps much cooler and drier during the summer. However the HTPC case design is obviously even more compact and breathes even less than my PC especially using only two 92mm case fans, and it's tightly tucked inside my AV console. The console is fully open in the back though where the hot air is exhausted, so all in all the heat build up is rather limited. Ryzen 5 2500G, Wraith 2.0 cooler, running stock. CPU temp 30-32*C all year round at idle running1600MHz circa 5W. No noticeable gap between package and individual cores temperature - as expected with these rather low TDP APUs.
Laptop is Acer Aspire 3 with probably about the lowest performance config that series offer: i3 N305, 8GB RAM. Got it on a deal around 300$ USD, and for that kind of money it's truly a surprisingly slick and efficient thing. For the concerns of this thread, an interesting feature of the chassis is the centralized placement of the exhaust trap and the fact that it creeps up, from the back, into the upper surface of the deck. I'm pleased with the rather quiet operation of it, and I think the fact the exhaust trap provides a greater surface and wider dispersion direction helps greatly with reducing "hissing" noises, while it also ensures most of it is free of any fold or bunching of textile that could possibly constrict airflow with regular corner/outer rim placement, whenever you use it on your lap (while clothed, you know) or might prop it on a matress or on a pillow or sitting into a laptop sleeve when using on the go, or whatever. Ok... so this N305 runs pretty wildly on idle, anywhere between 600 and 1600MHz, mostly around 1000-1200MHz and circa 0.8W. CPU package temp on idle tends to settle around 40*C with the laptop rested on a pillow, to show worse case scenario of air intake/exhaust, but at idle I don't expect the intake part of the deal for any laptop (nor ambient temps within normal interior variances, for that matter) to have any big effect on CPU temp due to the blower exhaust fan(s) design.
Of course we all realize in this particular thread that idle temps have little to do with CPU cooler performance, or ambient temps within a short timetable/at a specific point in time, nor is it so insightful of the CPU itself or how smart the build is when rather logically perfected for thermals under significant load, as much as they will be impacted by airflow. Ambient temps will surely gain noticeability in their impact within particularly good airflow situations for idle temps, but logically speaking, considering a computer is mostly used indoors, total ambient temps variance over a full year would be... what... around 10*C in any typical home settings, much less than that in nowadays most often tightly controlled ambient settings, so day to day and week to week, ambient temps are largely unaffecting. Idle temps mean absolutely nothing except indicating more or less restricted airflow and/or extremes of hot/cold weather in homes with insufficient/deficient/absent ambients control - or a user willingly keeping extremely cool or warm indoor temperatures either through their range of control, or through cruder measures like cracking the window open in the winter.
