Running hot!!! Max temp for Intel 945GC Northbridge?

So it's warming up here in the UK and I'm getting worried about my fileservers NB temp

A couple of pics:





The temp sensor of the Coolermaster (the thing with three blue circles ) is shoved inbetween the fins of the NB heatsink and its reading an alarming temp! 70c! And thats just the heatsink, I don't even want to know what the actual temp of the NB chip is! Plus the motherboard has no sensor for it anyway. The temp on the LCD display is the air intake temp, just behind the mesh at the front - bottom of the PC. Do you recommend I purchase a small 40mm fan for the NB or will this temp be ok? The case already has 1-140mm front intake, 1-120mm Exhaust and 2-120mm side panel fans blowing into the case. I'm getting worried my server could go POP! at any minute

And just if anyone asks: I've swapped temp sensors between the Coolermaster and the built in LCD and both temp probes report the same so no faulty sensors. It does burn if you touch the NB anyway!

The Tc-max (Case Temp. Max) surface temp., measured at the geometric center of the die, for the 82945GC (G)MCH is 99 °C. The correct method of measuring the MCH temp. is to install a thermocouple in a milled slot in the base of the heatsink.

I've just seen this on the Intel 945GC data sheet:

I might get the drill out then, I think the results will be scary tho
