Ok, so I've decided to use Prime95 to hammer the CPU for a while

Some observations from SpeedFan:

* Core 2 is consistently the hottest.

* Core 3 is consistently the coolest.


This is a case with tons of fans in it... lol. I'm betting it's about 


* Either I've botched the install of the stock heatsink, or the stock 
heatsink is barely adequate. Max observed core temp so far is around 


* The system is stable. No errors yet. There's no sign of throttling down.

* The weird thing is when the system is idle, it does throttle down the 
processor. I've seen it run at around 1.8ghz when there is no load.

Maybe some tolerances in the temp sensor. After all, they're not there for
high-precision measurements.

What type of processor do you have installed?

For my Core i7, the guys at the shop told me (after having checked on the
internet and in the Intel specs) not to worry about the core(!) temp of, IIRC,



The overall "CPU temperature" is a different thing of course; if *that* reaches

roasted by then :P

Also note that other architectures may have totally different limits of course.

That, I was told, would be the most reliable criterion: Before reaching critical
thermal levels, the CPU would try to throttle itself down or, if the OS wouldn't
allow, shut down completely.

My system actually even chooses to overclock itself a bit (21x instead of 20x),
so I guess it must be more than happy with its own thermal status.

And after all, why not? If you don't demand power, the system can happily
throttle down - not to prevent overheating, but to save energy.

Holy! I get freaked out when mine starts hitting around 110.2F, or 
42.4C... And I am "fairly" sure that I start to see system stutter and 
more lag in games, when its hitting that, where are at 102F/39C, things 
run with little or no problems at all. I constantly fight with the 
others in the house because my room it usually 5-6 degrees warmer than 
the rest of the house, and the morons put the thermostat right outside 
the door of this room.

Mind, this isn't the temp from the internal sensor, its from one placed 
against the chip, and showing on the front panel, so it may be higher in 
reality. Still.. Yikes..

Hmm. Ok, the sensor on the front is showing 98.4->99F/36.88C->37.22C, 
while the sensor software is saying 38->40C. GPU is showing 48C, but I 
also have temps 1, 2, 3, HD and two cores (its a one core processor), at 
25C, 36C, 71C, 40C and 49C respectively. The 71X is showing a flame next 
to it, which I presume isn't necessarily good. lol

Yep, not too good. Finally figured out (nice of them to label the things 
sanely in the program I downloaded), that it is the Northbridge going 
that high. So, took a look. Seems the MB I got in here is an earlier 
one, which only has a passive sink on it. There goes another $20 for a 
monster cooler and fan, assuming I can manage to clip the damn thing on 
without pulling the MB out of the case (why the frak don't they hinge 
the underside with a clip shut door, or provide openings where the tie 
downs for the main chips are... :p
