Mac Pro running at 63 degrees - too hot?

I downloaded the istat widget and my Northbridge is always around 63-65 degrees.

Is that a problem?

Edit: Sorry scrap this thread - a simple forum search answered my own question that it's fine.
 
according to istatpro widget, my north bridge is running at 85 degrees celcius.

i'm always worried about that but it hasn't caused a problem yet.
 
Mines about the same. But if you rather it was a bit cooler you can use smc fan controll and bump up the fan speeds to around 900 rpm with very little extra noise
 
That's a fine number. Mine was running around 70C on full load with all processors in use.
 
Mines at 63 all the time, feels like it's roasting in the office but all is fine, Northbridge can run a lot hotter with no problems.
 
Northbridge will run hotter than the Processors due to the Passive Heatsink.

Unless your getting 90 Degrees Celsius Plus, Don't Worry.

Mine's on 56 degrees on 1GB RAM, proc loaded. Added another 2GB RAM increases it to average 62 degrees on proc load.
 
67 northbridge - way higher than anything else in the case.

HDs are in the low 30's and that's what I pay attention to!

Fans never seem to bump up at all except at boot. Even with large aperture library conversions, video encodes, and game playing.
 
So is there a general consensus on:

- when you should worry about your Northbridge Temp in the Mac Pro?
- what the MAX temps the Northbridge in the Mac Pro can handle?

My Northbridge under normal load seems to be around 73c / 164F.

My Mac Pro fans are at the lowest default setting. The Mac Pro NEVER kicks up the fans itself. If I use smcFanControl, I can kick the fans up and that number drops.

How many people here use smcFanControl all the time and set higher defaults? What settings for RPM do you use?

Sorry should have been more clear. Is there any documented data on these questions?

Not that I don't believe the 2 individuals in the previous posts, but I would really like to get some documentation from a tech source, Intel maybe, on exactly what these are rated for.

And the 2 previous posts have a difference of 40C between them. So if it's rated up to 130C....why should I be worried at 95C?

Northbridge is always at 58-63 :) depending on usage, if its ove 90 degeers then start panic, not a lot ;)
