What the heck is CPU hysteresis temperature?

[nexialist]

I monitor my CPU temp with the VIA hardware monitor v2.04.

I run a KT7-Raid/bird 800, 128 mb mosel mem. My system usually runs around 53-55 CPU temp and 40 CPU hysteresis temp. Which is more important?

This seems kinda hot to me and I have not even maxed it out because I"m not really a gamer, nor have I attempted to overclock (not yet) . It looks like a Taisol heat sink/fan combo (CPU/heatsink were premounted on mobo so I didn't remove to check).

It's in an Inwin 500 case but does not have a case fan.

Thoughts/ suggestions?

Hmm...I know what hysteresis means in the medical sense, and based on that I would venture to guess that it means the difference between your starting temp (cold) and ending temp (warm). The term is used in describing the physiology of the lung (in medicine) and refers to the property whereby the compliance (i.e. stiffness) of the lung is different during inspiration than it is during expiration. It shows much better in diagram form.

It means your system is overheating.... get a case fan

Another analogy would be (for example) measuring your tire pressure and the gage will lag behind the actual pressure until it overcomes it's internal friction and inertia. (Sheese, I hope the thermodynamics people don't read this thread before it goes off the deep end)

You can change any of the temp values you want in the Via Hardware monitor. For instance, based on the typical temps you describe you might want to set CPU Overheat temp to 60. Then, if desired, you can also activate any of the alarms to go off if one of the pre-defined thresholds is reached.
