57 degree northbridge when idle, no OC, too high?

Hey guys,

I am a novice when it comes to building computers, this is only my third one. For some reason, my northbridge on my MSI 790FX-GD70 is giving a reading of 57 degrees Celsius. I literally just built it, and turned it on, and from my understanding, there is not something I could have done to cause the northbridge to be running so hot. Does anyone have any suggestions for what could be causing this, or a way to correct the issue? I have not overclocked anything, and I installed a cooler master hyper 212 on the CPU. My setup is as follows.


2 x Gx2|GSKILL F3-12800CL7D-4GBRM
2x VGA SAPPHIRE 100245HDMI HD4850 512M
CORSAIR|CMPSU-750TX 750W RT 1
250G|SAMG 16M SATA HD253GJ % 1
SONY|AD-7240S-0B % 1
CPU AMD|PH II X4 955BE 3.2G AM3 1

Using the Antec Three Hundred Illusion case (the one from the $750 gaming rig)

  1. 57c isn't hot; it's higher than normal, but alot of other factors, such as room temp and your case cooling fans may be affecting the higher reading. You can get an aftermarket northbridge heatsink, but if you do, save your old one for warranty purposes. I try to avoid modifying any motherboard, especially the expensive ones; you might need to rma it later, and the companies inspect the boards carefully for any damage or mods.

    It's not really that hot - my X58 northbridge idles at 72C, and after a good day of gaming, it's hot to touch. The max temperature for the NB on the MSI 790FX-GD70 is 80C - 57C is pretty far from it.
  3. Thank you guys, I appreciate it.
