Asus m5a97 r2.0 with AMD fx-8350 and AMD RX480 northbridge overheating?

post #1 of 10
Thread Starter 
Hello

I played little bit with infrared thermometer and measured over 80 celsius on northbridge heatsink is it too much should I worry about it?



measured under full load

without any overclocking for now




system info:


ASUS M5A97 R2.0

AMD FX-8350

AMD Radeon RX 480

Kingston HyperX KHX1866C10D3/4G 2x



northbridge




Inside case/ airflow:




VRM heatsink? only 60 celsius

I would worry yes. 80c on the HS is excessive. What was room ambient temp?

I believe Asus recommended max NB of 60c for a safe point back with the CHIV-F. (link in my sig)
Even on those most didn't have issues with NB temp unless they had multiple GPUs. Some early units came through with the incorrect stand-off length which was another issue. Some members had to file the length of stand-offs to proper height. (another link in OP CHIV thread in sig). You didn't happen to dislodge it on accident by any chance?

Add active cooling to both VRMs/CPU Socket area and NB (old case fan and stock HS fan?) and you might also consider replacing NB TIM/Thermal pad if it's dried out or aged too.

If that top fan is exhausting out of case it might be pulling heat off GPU onto NB. Might try it as intake (if it isn't already)

There are some pics in my rig sig for VRM/Socket fan mounting ideas

Thanks for reply,

room ambient was around 25 degree celsius.
I think I did not dislodged anything, motherboard is still under warranty. Active cooling is good idea I definitely considering it, but now I'm also considering returning matherboard to dealership, my system frozed more than once, I was thinking it's a bad amd drivers on new RX480 graphic card but now I thinking it can be overheated chipset, or can not be?

If you have the option to return/exchange the mobo and you're thinking of OCing by all means think of upgrading.
Current mobo only has a 4 + 2 Phase count which isn't enough for an FX8350. I wouldn't go with anything less than 6 + 2 or better yet 8 + 2.

IMHO what you have is a bare minimum budget board for a 8xxx series chip. (not a good thing)
It might be okay if you can lower temps and run only stock but I highly doubt it'll do much more as you can already see with current mobo temps.

An experiment you can try is to move the 480 down to the lowest 16X slot and see if that lowers the North Bridge temperatures. Your manual should say which ones to use.

Thanks for the idea smile.gif

Nice, but you do realize that is the NB HS right?
The VRMs are up/left of that.

If that helped to lower temps try another fan on the VRMs too.

I was thinking that temperature what is on VRM is just ok, is it not?

At 60 the VRM are fine but the cooler they are the less power they use and thus run even cooler. Which is why I have a fan on the NB and the VRM.
