MB: part the heats up..

[yuriekatz13]

i wanna know what part of motherboard heats up

its kinda annoying to see your MB temp at 38c~41c meanwhile my CPU at 30c (load)

even when just using browser my MB temp at 36c~38c meanwhile CPU at 18c~24c (with apps at the back)

my MB is just your regular type.. not full, not mini.. just regular..
and its a gigabyte.. i really find it strange to be at high temp constantly..

i can somewhat DIY.. so if i know what specific part is heating up i might able to do something with it.. and yes.. already google but result are mostly CPU and heatsink related.. kinda sucks..

thnx in advance 😀

The temps you get really depend on where the sensors are. 30-40c for a motherboard temp is perfectly normal. Motherboards generally do not overheat or has issues with heating. You could increase airflow to lower this maybe a couple degrees but you don't really have an issue with temps.

The voltage regulators are the part of the motherboard that generally heats. It is the heatsinks around the CPU. The type of CPU cooling affects the voltage regulator temps. A AIO radiator that moves no air in the area of the CPU socket will cause the voltage regulators to run hotter.

ohh the voltage regulators huh... kinda explains the thing now...

my voltages are not normal even tho im not OCing my PC..

1.5v -> 1.524v
3.3v -> 3.324v
12v -> 12.24v
5v -> 5.1v
CPU max volt at 38 ratio : 1.412v (AMD OD) -> 1.5XXv (CPU-Z)

maybe this is the reason?
i've already devolted my RAM to 1.490v at BIOS but its still at 1.512v in BIOS/AIDA64/HWiNFO64
strange for me... is this normal?

Your voltage variations are 2% or less. The bottom three values are from your power supply not from the motherboard voltage regulators. The quality of your power supply matters just as much as your motherboard voltage regulation.

Correct undervolting can reduce temps. but how much isn't really clear. A little .05v dip won't do much at all.

You are asking about a patient? You've come to this hospital but we can't see the patient. It's nice that you want to address this issue. We first however need to know some specifics about what's under the hood. You can use https://www.ccleaner.com/speccy/download. C+P the summary page or offer a screenshot.

. When you are replying look above the text box at all the wonderful tools. See the icon that looks like a Polaroid pic? Click it. A box pops up. Paste a example.png
example.jpg or a example.bmp and click okay. I used https://s5.postimg.org/56wxtovnr/2018.png. I also have a Vivo Titan case and a Seasonic G Series 650W 80+ Gold PSU.

What's going to be important is the probably just the motherboard. Take a look to the left and above the CPU socket, where you installed the CPU.

is just an example. There's a little strip of black and red next to the place where a 8 pin CPU supplemental power connector would be attached. That's a tiny heatsink. It's a passive heatsink that helps to wick heat away from the motherboard and at that point internal case fans and efficient airflow become important. Without correct airflow the motherboard and its passive coolers won't work too well. Now, take a look at this board

See those heatsinks? Bigger, beefier and more of them. That motherboard should be cooler thanks to the extra heatsinks and their sizes.

People know they aren't going to OC so they purchase a budget board. The companies pumping those out know this. These users won't OC so we don't need to worry about cooling too much. They do JUST enough. This other board is for Intel processors designed to be OC'd(those with a K in the Sku like 8700K). The user will be pushing their CPU pretty hard so we need some extra cooling. Their board costs $110 and allows overclocking. Even if one won't be overclocking those board come with some other advantages. Those advantages extend to electrical needs as well but that's not the issue at the moment.
