Does fanless motherboards have faulty design?

[Bill_Bright]

they were at one point a necessity

but modern ones... ...have improved

As noted above in post #9 and #20, they sure were a necessity, the devices themselves have improved in efficiency too. But also noted and just as importantly, larger, more efficient heatsinks, larger case fans, and better case cooling all have improved since "back in the day too".

That said, some, but not most, boards today come with fans.

Since, I believe we all agree on this now - I believe we can get back to mclaren85's question and state with certainty, "No! Fanless motherboards do NOT have a faulty design". MSI just expects, and rightfully so IMO, that their top tier motherboards will be mounted in a quality case that provides quality cooling.

I will also note the following,

I carefully monitor the chipset temperature, and while the system is idle, the temp is 56C at minimum,

According to your screenshot, you are referring to TMPIN3. That is NOT the chipset but, as seen here,

What is TMPIN3?
TMPIN3 is actually a temperature sensor placed near GPUs or VRMs. This thing will keep a track of your GPU or VRM. Of Course, your GPU will always have its own temperature sensing system. But, your motherboard also does its job with this sensor. Again, not all motherboards will come with these sensors.

If you are seeing a result for TMPIN3, this is most probably highlighting the temperature related to your graphics card.

TMPIN2, "IF" used, is typically for the south or northbridge (chipset).

In any case, 56°C for either the VRMs or the GPU is only "warm"!

And note there are no industry standards as to specifically which device either of the TMPIN2 or TMPIN3 sensors are required to monitor, or where exactly the sensors will be placed. In fact there are no industry standards even requiring those sensors be used. The point being, these can NOT be used to compare one motherboard to another.

Last, those sensors probably cost $.10 a dozen to manufacturer. They are NOT precision measuring devices. If you really want an accurate measurement of your various motherboard temps, use a quality Laser Guided Infrared Thermometer Gun.

The fan was put in as a safe measure is all, dont like it? Put a custom heatsink on.

As you stated, there is no international standard. I've checked the bios screen if the reading are accurate.

I've checked the bios screen if the reading are accurate.

Except the BIOS uses those same $.10 per dozen, very low tech sensors. So "accuracy" should be taken with a grain of salt. Consistent may be better.

It probably should be taken very much like typical bathroom scales. We should never assume they are very accurate. So if you weigh 150lbs today, they may say 147lbs and that's okay, as long as that same 150lbs reads 147 tomorrow and the next day and the next too.

Note these sensors are typically diodes that present a certain amount of resistance through them as the temperature rises and falls. Nothing high-tech. And the diode's circuit then simply converts that value into a hexadecimal number. The software (either the BIOS software, or HWMonitor, HWiNFO, etc) converts that hex number into degrees. Again, nothing high tech. So again, accuracy may not be a given, but they should be consistent - that is, if off on the high side 1%, then always off by that same 1%.

The problem with measuring temps in a computer is there are too many variables that are never consistent either. The load is constantly changing. Even ambient (room) temps too. A CPU, for example, can go from cool to hot in just a few clock cycles and there are ~3 billion clock cycles per second with many CPUs.

So while watching our temps is important, I don't worry much about them unless they "sit" high for more than a few seconds. And when that happens, it typically means I need to wash my filters.

One more thing to add more confusion.

Because this measuring and converting numbers is all done in digital formats, the actual measuring is done by "sampling". And it is probably only done once every second or maybe every several seconds. And each monitoring program can set their own sampling rate and sample time, which probably starts when that specific program starts. This means Program A can report 35°C and Program B can report 38°C and both are correct!

Clear as mud, huh?

Think about your fan placement and the way air is passing around your case if there is good airflow over the chipset that's all you can do.
As others have said 60°c ain't hot for a chip if it's working at load were only talking 10 or so ° higher than my ambient temps on hot summer days. That's when you need to worry about cooling.

 

[Zubasa]

That's a very, very nice work! But my problem is not about VRMs, but the passive cooled chipset

To sum it up, the X570 chipset is almost identical in design to the IO die within your CPU, meaning it should be able to run at the same temps without issues.
It is absolutely safe until you run into 90C+.
