Northbridge Temp 60C

[.Im#NuMBeR1]

I know I need to update my system specs on my profile... I'll do that shortly.

 

Any idea of what I can do with the Northbridge temp? Suggestions (real and useful suggestions, no "get a new board" nonsense, please)

 

Yes, my CPU will be overclocked again soon but regardless even if the CPU is stock speeds (4GHz for FX8350) the NB is always in the 60Cs.

Either put a fan on it or leave it alone since there's nothing wrong with that...

It's fine. Perfectly acceptable temperature.  Up to 85-90c reported there is perfectly safe. 

 

Chip is rated for up to 95c operating case temperature.  Account for around 0.2c..0.5c for thermal paste / adhesive , around 3-5c for heatsink ... still have up to 80-90c.

 

See datasheet, page 40 : https://www.amd.com/system/files/TechDocs/48691.pdf

Interesting. When gaming while overclocked from 4GHz to 4.4 or 4.8GHz it heats to 70-80 when gaming depending on room temp. I’d assume this is fine? Because when at 70-80C it’ll just shut down.

I doubt it's the northbridge that causes your system to shut down. 

It's most likely the VRM on your motherboard, or the cpu or other issues. 

 

Easily testable : unscrew a case fan from the case, position it above the heatsink of the northbridge... repeat process.

 

Anyway... you know the saying "polishing a turd" ... you're wasting time trying to overclock an already power hungry very inefficient fx-8350

Let me ask a few questions here.

When you clock it up, are you using all CPU multiplier or a mix of CPU multiplier and bus speed?
I will say the Northbridge doesn't need 1.6v's to run at 200, it will do fine with just 1.1v's and run cooler too.
In fact a rundown on the settings you're using would be nice to see.
 

Personally I doubt it's the Northbridge or VRM's, the Sabertooth/Crosshair boards have the best VRM setup out of any AM3+ boards period.
I've ran enough of them to know that as fact and have the results to go along with it.

So you go all auto with voltage - Nice.
Still doesn't tell me if you use all CPU multiplier or a mix to the get the speeds you run as indicated.
If you'd show that I may be able to make a few suggestions.

BTW just so you know - This is me and I do know what I'm doing with AM3+ and the board model you have too.

Bones`s SuperPi - 1M score: 9sec 141ms with a FX-8320

So let's see those CPU mulitplier and FSB settings you use when clocking it up.

It's set to auto with the D.O.C.P.

OK - I was wondering how you were getting the clocks from it.
Normally on air or even water they don't like CPU multiplier over 20-21 (Depending on the chip) as you have it in your validations so you're at the "Reliable" limit with that.
Voltage, if accurately read by CPU-Z is good - Very good in fact.

The max norm CPU-NB for any daily useage is about 2400, give or take with some CPU's tolerating a little more, some not liking it above 2400.
You can run that with ease using just 1.20v's max, if that much to the CPU-NB and do bear in mind as that goes up so do CPU temps.

Your chipset running at 60c is fine, 1.15v's for it is good since many 990FX chipsets will go way up with less voltage than you'd think - The max available in a Sabertooth 2.0 for example being just 1.25v's and some of those can top 300 with ease.
My Sabertooth 3.0 can hit 360 FSB with that or even a little less and it's selectable voltage (Max) is the same.

DIGI settings do not need to be jacked up, 100% is fine for everything aside from heavy OC'ing like I do.
I did the 8.3GHz run with 120% to the CPU and CPU-NB so it's not required to get what you would being on air or water, plus that makes everything else run hotter too including the VRM's when you raise those percentage values up.

You're on the right track and doing good, 4.5 as a target for a daily build is excellent in itself, esp if on air. You can set a fan blowing around the socket area and place it so the Chipset/VRM heatsinks get some of it too, that will lower temps for all that a little.

I don't know if any of this will be helpful or not but maybe it will remind you of something or maybe it will make you think of something you haven't before.

I very much appreciate your opinions and thanks for the kudos on my overclocking.

 

I suppose I just don’t like my pc running ‘too hot’, and personally, to me, 60° is a bit too hot. Would it be of any use to clean and apply fresh thermal paste and thermal pads on the chipsets, VRMs and GPU die?

When you consider the age of the board, that could help.
The heatsink pad thickness is 1mm, any padding for the VRM's that's 1mm or 1.5mm will do but don't go over 1.5mm in thickness. 1mm should be easily obtainable and what to go with for this.
You can even cut a square of it for the chipset too, essentially doing the entire job with the same stuff.
As for the GPU die, it may work there too.
I can't really say what thickness to use but I'd have to guess 1.5mm padding for it, just be sure to have some 1mm onhand for that too just in case. You'll have to also repad the GPU VRM's when  you separate the cooler so be ready for that too. Clean everything with acetone to make sure it's clean, trim and apply the padding, remount the heatsink(s), then test.
Keep me posted on how it goes.
BTW I'm about to repad my Crosshair V-Z too - Already have it stripped down, just need the padding to do it with.

I won't be able to do it for a week or two but do let me know when you've done yours, show me some temp differences if you have any from repadding.

I'll probrably be waiting for that long at least on my padding and I haven't ordered it yet.
Since it's already torn down I can't show any differences aside from it no longer throwing a chipset overheating error once done.

Anyhoo, once I do get the stuff and repad it I'll show the work done.
