Asus Crosshair Formula IV 890FX, NB, is mine running too hot?

PC probe II says NB is running 40C @ idle and 52C with a work load on it (South bridge is consistently 8 degrees cooler at all times). Is this considered overheating for this board? I've read some people say that under loads their north bridge never gets over high 40's while others have said 70C in BIOS till crash.
I also know people have had to file down the standoffs and/or replace the thermal paste on both north and south bridges with these boards and I am wondering if I should do the same.

No, the temps are okay'ish. No, don't yank-off parts of the MOBO.

Q - Are those CPU or NB temps?
Q - Any OC'ing?
Q - What's your ambient temp {room}?

Those are NB temps. The cpu (1100T w/ noctua D14 heatsink) runs @ 29C although I thought is would run 10 degrees cooler.
Not overclocking currently, did try using Asus's TurboV Evo and once the CPU hit 4ghz the system was unstable/crashed. I thought for sure I would be able to OC to 4.5ghz without problems.
Ambient temp is 80F

Here all the specs:

CPU - Amd Phenom X6 1100T BE 3.7GHZ
Mobo - Asus Crosshair IV Formula 890FX
GPU - Sapphire 6970 2GB
PSU - Enermax EMG700W
Case - Silverstone Fortress FT02B
RAM - 6GB Corsair DDR3 1600
Crucial 64GB SSD (boot drive)
Seagate 1.5 TB 7200rpm (storage/backup)
Monitor - Dell Ultrasharp U2231h
CPU Cooler - Noctua NH-D14
Win 7 Pro OS
Mouse - Logitech MX518

What 29C = 84F when you turn it on? Your ambient would be 65~70F max to keep Here's a video for you http://www.youtube.com/watch?v=NntHGIO0Noo in reality the roles are reversed.

I don't use or recommend ANY Utility to OC. Try 1.50~1.55v

29C after boot and w/light work load....

I am new to this so I will have to learn to OC through the BIOS instead of Asus/utility...

I 'wish' they would work, but the Utilities cause FAR more problems than they solve; GA are the worst and ASUS is a close second. Great MOBOs - crappy software.

Download Prime95 and CoreTemp, and uninstall all those ASUS Utilities. For a baseline run Prime95 & CoreTemp for 15~20 minutes.

BIOS:
Load Defaults {resets the BIOS to Factory}
* If you enabled AHCI then change that value from IDE -> AHCI
AI OC Tuner -> Manual
CPU Ratio {+ key till 20}
CPU NB Voltage -> {Manual}
CPU Voltage -> 1.55v {yes you'll get a red light on the MOBO LED.
--
If you post your RAM Part Number, I know they're Corsair 1600, then I'll add those settings.
--
CPU Q Fan -> {Enabled}
CPU Q Fan Mode -> {Optimal}

Save & Exit

Run Prime95 & CoreTemp for 10 minutes and WATCH your temps. If they exceed >75C and are climbing quite Prime95.

Tools you'll need:
1. Prime 95 as a "Stress Test" [overnight once stable]

2. CPU-Z for Settings Summary

3. CoreTemp 0.99.x
http://www.alcpu.com/CoreTemp/

4. Memtest86+ to check memory corruption
link - http://www.memtest.org/

5. HWMonitor
link - http://www.cpuid.com/softwares/hwmonitor.html

The above will give you >4GHz, if you have a problem change CPU Ratio down one notch. Also, to undo everything boot into BIOS -> Load Defaults -> Save & Exit. Don't be afraid of BSOD or failures.

Let me know what happens.

Well that's not the RAM I would have choose; Tri Channel set on a Dual Channel MOBO. If you're having issues then pull one of the sticks. No you cannot add a single stick later, the second set to run in Dual Channel 'should be' matched to the first set.

1600 MHz 9-9-9-24-2T @ 1.65v

From above:
--
DRAM Frequency -> DDR3-1600MHz
DRAM Voltage -> 1.65v {or next value higher}
DRAM Timing Control {enter}
/9-9-9-24
/DRAM Command Rate -> 2T
IF needed:
NB Voltage -> 1.28~1.35v

If 8GB is the 'goal' the bang for the buck -> CORSAIR DOMINATOR 8GB (2 x 4GB) DDR3 1600 Model CMP8GX3M2A1600C9 http://www.newegg.com/Product/Product.aspx?Item=N82E168...

2X4GB is more efficient {faster} than 4X2GB. Keep in mind, if the goal is to OC then you can go as fast as 2000MHz RAM.

6-Core AMD only:
CORSAIR DOMINATOR GT 8GB (2 x 4GB) DDR3 2000 (PC3 16000) with Airflow Fan Model CMT8GX3M2A2000C http://www.newegg.com/Product/Product.aspx?Item=N82E168...

In addition to the QVL and Tested, the following will work -> http://www.corsair.com/memory-3/amd-memory-solutions/ph...

Good day mate,, Im having the same idea as you, but, pending on you pc case i might be able get you try some thing. Like your crosshair iv , mines high too. Bios temp monitor goes as such cpu 31 , mb 37, nb 48 and finally sb at 35. You will problibly find most nb are high, read it all the time.
To my project i did, what i have did has brought down the temps, more after ive told what i have done. You know those ram fans, well i put one on the flip side of mb, their's area just where the nb heat sink and cpu are exposed. ive did a crap job of sticking the fan in, but hey.
my temps are now, cpu 24 , mb 24, nb 38, sb 27. So what you reckon?
Hey its cheap , and its cooler by alot. have fun.. Robs

Hi , I posted a cheaper sollution last night some ,lol, but im new on here so can find it now.

What i have done to bring my temps down in idle.

cpu, from 31c to 24c,

mb from 31c to 24c,

nb from 48c to 38c,

sb from 37c to 27c.

Room temp 22c.

Ive had the same idea removing the nb and sb heat sink and lapping the nb chiptset, and using a better thermal grease, and aslo i saw a youtube vid on another tech dude removing the stand off bots and filing one of them shorter a nic to get full contact with the nb. Cant find the video any more??
Well i all i did was to put a ram(memory) fan on the flip side of the mb, just over the exposed part of the cpu and nb. Noisey as hell to start because i have insulated the fan, you cant hear it after it bot up ; ). I think there might be a roar of laughter after reading this, lol. I had fun trouble shotting with out ripping my heat sink off and bugging my warrenty, lol.
