Fitted an Arctic Freezer to my cpu over a year ago, runs as cool as a cucumber and maybe up to 50 on a srsly high load extended gameplay. Replaced a leaky water system, the fan was cheap as chips too, although pure copper heat extractors and huge vanes to release the heat help when it matters most.

Just wondering if anyone else has any thoughts on these numbers. I have been building PCs for quite a few years, and these are the lowest numbers that I have ever seen.

Unless you are sitting in cool storage (or someplace similar with temperatures between 0 - 10°C), these numbers are bogus. As a general rule, it is impossible to go below ambient room temperature, for rather obvious reasons.

Edit: sometimes the unit conversion is the culprit, e.g. incorrect conversion between Fahrenheit and Celsius can indeed produce similarly weird numbers. Check your BIOS etc. if the temperature is indeed reported using correct units.
Also, try other temperature monitoring program.

Have used the same programme for years and it's been about right all that time. Ambient is around 20 - 24 ish. And of course it can be cooled below ambient room temperature - that is what forced air cooling does. Try sucking in quickly through gritted teeth and you can feel a definite cooling effect - certainly well below ambient room temperature. I used to have an asus programme that came with my asus motherboard (AI Suite ||) which is used often to control things like fans and overclocking etc. Unfortunately it has ceased to function since the last windows update, an no ammount of uninstalling / re-installing etc seems to get it up and running.

I don't care how long you have used whichever piece of s...oftware.

You cannot go below standard room temperature, unless you are using some kind of exotic cooling solution - and that cooler of yours is rather conventional, it is even fairly mundane.

So stop rewriting laws of physics and start looking for improperly set up temperature readout.

Yes sir. I will consider myself severly punnished.

By the way - how come people use ordinary fans to cool them during hot summer weather. Are they all telling lies and fan salespersons are making a killing based on a lie?

You are welcome...

Any temperature equal of lower than the ambient room temperature reported by anything (BIOS, program etc.) is suspicious and most likely bogus.

Possible sources of this problem:

- as I said, improper Fahrenheit -> Celsius (and vice versa) conversion

- tinkering on the part of the board manufacturer - in my years as hardware support technician, I have seen quite a lot of mainboards with "doctored" temperature readouts - MSI is especially very fond of this type of tinkering, if for example, the CPU temp drops by 30°C just because of BIOS update, while everything else has exactly the same temperature, it is suspicious, to say the least

Really... try something different and check, if there are no misreported units of temperature.

I am going to tell you a trade secret - they don't.

It is summer, which "sorts the grain from the weed" and in summer, heat based failures are several times more common, than in winter.
(and don't forget that a lot of places have some sort of air conditioning these days)

Google can be your friend: https://science.howstuffworks.com/question22.htm

Indeed... some further reading from the very site:
https://science.howstuffworks.com/nature/climate-weather/atmospheric/question70.htm

"For an inanimate object, windchill has an effect if the object is warm. For example, say that you fill two glasses with the same amount of 100-degree water. You put one glass in your refrigerator, which is at 35 degrees, and one outside, where it is 35 degrees and the wind is blowing at 25 mph (so the windchill makes it feel like 8 degrees). The glass outside will get cold quicker than the glass in the refrigerator because of the wind. However, the glass outside will not get colder than 35 degrees -- the air is 35 degrees whether it is moving or not. That is why the thermometer reads 35 degrees even though it feels like 8 degrees."

I was just interested in the conversation and wasn't really sure -- felt that matching the ambient air temp was the correct answer, but wanted to be sure -- now here in South Texas -- when it is 100 F and the Humidity is near 98 % as well -- the opposite seems true that the breeze makes you feel hotter since little evaporation of your own sweat occurs so there is no cooling effect as in less humid climates --

I never thought my curiosity would stir things up this much. It's all very interesting of course. A friend of mine has a nice little probe type thermometer which he is going to bring to me in next day or two. I'm going to put it as close as I can to the CPU just to satisfy my own curiosity and see just what is going on down there. Will post results when I have them. Am also going to look in the bios later see what that says.

Annoyed that I still can't get my Asus AI Suite to work anymore. Was a real nifty piece of kit.

Yeah, that is the difference between us, as living beings - and computers. Though personally, I can speak about wind chill in a classic sense of this word, fortunately for me.

I am often saying in summer to my users: "this is the part of the year, when people can endure higher temperatures, than their computers can - we will (after some time) accomodate to higher temps, our machines will not, so consider yourselves warned".

And indeed, practically all spectacular computer based incidents I ever witnessed, happened in summer.

In my experience, once the ambient room temperature goes above ~25°C, it starts to be rather risky to run anything demanding on desktop computer, as their cooling systems are often unable to deal with additional heat (there are numerous exceptions, of course, but as a general rule, it is better not to push the cooling systems to their limits).

As for laptops - well, it really depends. Some of them have no problems at all, some of them overheat even under normal conditions.

In my younger days I served in Arctic and Antartica waters -- but the ship was stationed on the East Coast of the US - so had to sail through the tropics to get through the Panama Canal to get to our duty stations for our different patrol areas -- Learned on my first cruise that the early computer systems (1978) were in the only compartments that were both air-conditioned and heated consistently -- reason why I volunteered to be the sateilite control officer so I can "hang" in those compartments --- cruise temperatures would range from - 60 F wind chill to +105F with 100% humidity

So now I am going to bow my head in shame. I have obviously made a big mistake. The original screenshot (in the OP) shows the prog' Core Temp displaying a very low reading. I have used this prog' for a number of years with no problems, yet somehow it suddenly decided to show these low temps. It's caught me out good and proper. This morning, i looked in the bios, and it was displaying about 33 deg (C) - very different. So then I uninstalled the Core Temp prog and looked for something else to try - HWiNFO64 is what I decided on. Here is a new screenshot> http://prntscr.com/i81wtc

As you can see, it is displaying 2 different values. The top one is very close to the reading I was getting with Core Temp, but it has 'Tctl' after CPU. Can anyone out there enlighten me as to what that might mean (I am guessing ThermalControl or something like that?) Can't seem to find any info as of yet.

The bottom reading is of course much nearer to the bios reading. Now I am confused as to what these 2 readings mean exactly.

When I get around to building my new pooter this year, I'll consider assembling it inside the knitchen freezer!! (Yes I am joking of course - fully aware of condensation etc (or am I ??))
