I built a new rig. a few days ago

FX 6300
GTX 970
16 Gig ram
cooler master hyper 103 cooler. (max 2000 rpm+)

I used HWinfo and noted that the CORE 0 Temps were 40-45 but the Core temp under the motherboard section was 65! at idle. While stress testing in prime95 for 6 mins, temps rose to 76 deg.
Please help!. Im using a Arctic MX-4 thermal compound. I used the short line method of application.
i have two front 120mm fans in pull, and one 120mm fan on the back in push configuration.

Note: I cannot change the cooler to HYPER 212.

UPDATE 1: Okay the temp at 75 deg. was actually the NB/SB of the motherboard, turns out the cpu was staying under 50 deg at 100% load. Thats good right? but what about the north bridge, south bridge heat sinks. they went high as 83 degrees while gaming? is that bad?

Northbridge is not very hot at all. Those chipsets can handle up to 110C before they shut down.

Yes, the heat may reduce it's life... But it'll still live long enough to become entirely obsolete before dying of heat. No worries there.

The northbridge on my Asus M5A99FX PRO R2.0 went to 105C when gaming and live streaming, that board lasted three years and died because my power supply crapped it's pants all over the system. Burned everything out except for the LED strips. I found it strange to see a CM V1000 fail so spectacularly. But to be fair, the 235W being drawn by the CPU at 100% usage while overclocked would have been an extremely heavy load.

AMD chipsets run warmer than those from Intel... Many motherboard manufacturers put a heatsink on the chipset that's just enough to keep it from burning out. So they will tend to run warmer.

What motherboard are you using? That's rather important information.

Also, 45 on the cores is not that bad. That's about what my CM Seidon 120V kept my 8350 when OC'd to 5.2GHz.

Hello,
I'm using a MSI 970 GAMING motherboard.
I Cleaned and re-applied the thermal paste, Now the core temps are 25 dec at cold boot into windows, at heavy load all cores at 100% the temps were as high as 50 deg . I suppose its normal right? But the north bridge temps were as high as 83 degrees. Thats what i'm worried about.

I have not O'Ced the 6300 in any way, they are running at 3.5 Ghz stock

Sorry for the Late reply, i had been out. SO, i narrowed down the problem, the back fan was inefficient at pushing out heat from the case, as it was running at a very low RPM. I Replaced the fan with a higher RPM fan and installed two TOP intake fans as well, now the north bridge is 35-40 dec C at idle and 58 Deg max while under load. Phew! Thanks for your help.

I am using a budget power supply for the time being (VS 650) i checked it with a multimeter for voltages, they are good, just hope it doesn't die anytime soon!

VS650 is fair quality. Not the best, but not expected to fail unless you draw power above it's rated specs for long periods of time. I mean, it's a budget friendly version of the CM V650, which I highly respect. In fact, I highly respect the CM V series as a whole.

My V1000 failed because I was far out of spec, drawing 6 amps more than it was rated to deliver to the 4+4 pin CPU supplementary power connector.
