What are YOUR 990FX northbridge Temps?

post #1 of 92
Thread Starter 
Hey guys. Over in the Gigabyte 990FXA Owners Club we have had some interesting discussion/Debate. The topic is 990FX north bridge temps. We have some people freaking out over the temps their boards are reaching under load and at idle. I have been assured by Gigabyte that temps of 60c are normal, and are "within spec". However after doing multiple google search's I cant find ANYTHING about the tech specs of the 990FX NB temps. I have however found that other boards also hit temps in the 50's or 60's at full load and is seemingly normal.
So I ask you fellow OCN'er's what are your temps on your NB? If you don't mind posting what board your using, and temps you get on your chipset along with at what voltage your getting those temps it would be great! Thank you for your time:)


I'll start it off. Baord is in my sig rig.
Board: 990FXA-UD3
Temps: Idle low 40's upper 30's, Load 55-57c
Voltage: Stock
Clcok: Stock

In my Sigrig Im getting to 65C on load. My old mobo was a cheap $60 one that I could even OC with and it would get to 95C lol
post #3 of 92
Mine was ~30c over ambient due to NO fans blowing in that area. Strictly passive.

CHVF stock volts and clocks.
Idle: ~30c in 23c room (taken at boot)
Load: max I read was ~54c for under 10 seconds before hitting 50c

With fan blowing only on the heat sink, load was 5c over ambient.

Which sensor is the NB? I have HWMonitor open right now.

SYSTIN: 44c current, 30c min, 49 max
CPUTIN: 36c current, 30c min, 48c max
AUXTIN (dud/unused sensor): 2c current, 1c min, 4c max

I would like to assume that your SYSTIN would be your NB, but I am not familiar with that board and this is only a stab in the dark at best.

Keep'em comming guys. I suspected that ALL boards(990FX) had high temps on the NB...go figure! lol. Thank you so far and don't stop!

Which temp would it be in open hardware monitor? My 2nd temp never passes 40-42 and my 3rd temp under load is always about 50 ishc. 1st temp I think is a crapped out CPU socket temp sensor stuck at 30c.

on the UD3 the temps are as follows
TMPIN0 = Sytem (Motherboard) Temp
TMPIN1 = CPU Temp(socket)
TMPIN2 = Northbridge Temp

the first temp sensor on the UD3 is going to stay at about 30c or so even at idle. its the "system" temp.

Keep the temps coming. So far its just as I expected:)

47c @ 1.37v to the NB under full load, strictly passive cooling.

My old MSI nf980-g65 NB was 92c on the low side and up to 101c under load.

If you drop into the 990XA-970A topic, we've had the exact same discussion about kind of high Northbridge temps.

Personally, mine used to peak at 72-3 before I applied some thermal paste to it. Now it goes to around 62-5 at peak.
