Can anyone explain this heat between a Mobo and CPU.

Dear Community,

I'm not a newb, nor am i an expert with computers.
I build this thing myself and it's been running for 4 years (OC'd).
The package is running at 4,3Ghz (stock at 3,5ghz).
Today i opened CorsairLink to check my temps just to look and it stated that my Motherboard Temp #2 is between 70-75C degrees lately, it's summer right here now so it's kinda hot but then again it states that my CPU package is only between 30-40C at all times and now i'm confused. Why is the Mobo Temp so high and the CPU package basically fine? I can't remember what temps i got from the Mobo when i first OC'd the CPU either since it's running like this for so many years already and i never have gotten any BSOD's or crashes while playing any games really.
So i'm wondering if this is normal for a Mobo Temp to rise up so high? And also the other two Mobo temps #1 and #3 are only between 30-40's.
If anyone can explain this to me, thanks in advance !

Not a newb nor an expert but better than someone who knows just enough to break his/her computer. A power user you are.

How many programs have you used to check your MB temperature? Speccy? HwMonitor? BIOS?

When asking a question relating to PC's it's usually a good idea to offer complete PC specs.

Consider

Look around the CPU socket. See those square and circular things(MOSFETS, chokes and other things that fly over my head). Now take a look around this CPU socket

. Notice anything different? Those huge passive heatsinks? The Asus MB should maintain cooler MB temps due its superior cooling design.

What motherboard? That is likely PCH temp otherwise known as chipset temp. If so 70-75c is normal for the chipset, if it stays at around that same temp even under full load then im pretty sure its the PCH temp, 70-75c is nothing to worry about. Depending on your mobo, vendor specific software like asus ai suite for example would likely tell you exactly what that temp is for rather than just saying "temp #2".

Yeah i'm running a cheap ass mobo that doesn't have such heatsinks. Thanks folks !
