Overheating motherboard?

[PostmanPot]

Got a friend with an Asus M3A-H/HDMI mobo with AMD 780G chipset. His mobo has been complaining that its temperature is too high. The warning is set at 45'C. The CPU temp is fine.

Is the North bridge running too hot if it reaches 45'C, or are we worrying too much?

The last post in this link - http://vip.asus.com/forum/view.aspx..._id=1&model=M3A-H/HDMI&page=1&SLanguage=en-us - looks to suggest that we are?

Thanks.

well like asus support said:

"The max temp for cpus is 60-65C.
For motherboards its 60C. PC
Probe and the hardware monitor in bios read the northbridge temp when its talking about MB Temp. "

my board runs @ 38'C and all its chips sets is covered with copper...45 isn't too bad. have you use speedfan for more realistic results? (anyway they test boards way past that temps) but can see why you are worried, if asus sets that as a trigger point, makes you wonder...

Can you maybe attach a small fan to the heatsink? Check if the temps drop then. Is the pc slow or giving any problems? Maybe increase the airflow in his pc case.

45 is ok. mines at 32 to 42 depending on the day.

Why not take the sink off and reapply some paste? might help!

Does he perhaps have a very hot vga card? Can cause the north bridge to over-heat quite badly.

What cooling does he have in his box? is the air moving or static?

Thanks for the suggestions and input guys.

It's a 7600GT, and yes, he does suspect it to be causing the north bridge to heat up.

2 x 120mm fans.

MOD it with a fan directly on the north bridge maybe?

I've seen people doing this.
