My TBird 1.2 is currently running at a nice, stable 1300mhz but the temperature range is fairly large. Here are the lows and highs as reported by motherboard monitor:
Low temp, after idling all night - 29c
High temp (max), 1 hour of 3D gaming - 51c
That is a 22c difference! Isn't that a little extreme? Will these kind of temp swings hurt the processor? Most of the time, during normal operation, my rig stays around 39c-41c when I'm working. Only after idling for an hour or more does it get down to 29c and only after intense gaming does it hit 51c. Current heatsink is an ALPHA PAL6035 w/Delta fan. I think this is probably the max the ALPHA wants to handle, but the spread still seems large. Am I really dumping the heat that fast? Any ideas? I think msidle is the reason I'm hitting lower than normal idle temps.
Will a better, more efficient heatsink make the temp spread lower?

VIDEO CARD GUILLEMOT KYRO II 64Mb(5ns)cooled with GOldenOrb 175/210
CD-ROM ASUS 50X

Those are exactly the same temps I get with a Duron 800@1000, using a Thermoengine with the stock fan.
I find that the range is usually bigger around summer, although I can't work out why, lowest temps stay around the same all year, but stress temps rocket.
If I can get hold of a 60mm delta offline, I'll see if that makes the difference.

Well, I think that the CPU idling program (msidle) has something to do with it.
Normal operating temps are around 39c-40c under very light loads. Only after things idle down for awhile do the temps get real low. I can actually "hear" the rig slow down, or go into "idle" mode and then watch the temps start to drop. My Duron 700@920 used to idle around 27c as well.
I have the (2) 80mm fans in the rear of my Antec case both exhausting and they set right by the CPU so this may help as well. Also, when the idle starts, I have the screen saver set to "Flying through Space" which takes very,very, very little CPU power which makes things drop down even more. Also, the GeForce2 is putting a lot of heat out while gaming as well. During "normal" operation, it doesn't heat up near as much as during gaming so mabe this attributes to the higher temps as well.
Any ideas guys?
This is the second CPU to do this. Is msidle doing all of this with throttling? Kind of like RAIN does on my K6/3........
