CPU TEMP climbing for no reason.

Recommended Posts

Something else you could check.

 

The next time the temp spikes and before unplugging the mouse receiver, check the current draw on the USB ports. Have all USB devices you use plugged in. If you are running Windows XP, right-click My Computer and choose Properties, Hardware, Device Manager. Double-click Universal Serial Bus controllers, double-click the USB Root Hub entry, and click the Power tab. Add up the amounts in the Power Required column. Your PC specs might be different but each port typically can handle 500ma.

 

If there is something wrong with your ports it might show up as drawing too much power.

 

Sometimes there are internal devices connected to a port, such as a touch pad that can increase the current draw of a particular port.

Thanks I didn't know about doing that I will give it a try. I will look when things are well and take note of the values and than check when/if the temps start acting up and compare the values.

I only use speedfan because all I need is the CPU temp in the tray, along with the hdd temp. I set it to put the mobo's cpu temp in the tray instead of the cpu's temp. I find it's more consistent and closer to the real temp.

Hmm, Speedfan is reading about the same as SIW?

 

And all of a sudden my clock speed has increased which I ain't seen before?

I judge by that pic that the maximum temperature your sensors can detect is 122C? And is your system water cooled?

Just a normal heatsink/fan setup.

Anthony, I use SIW as well but I do get a discrepancy in the sensors with SIW showing my cpu temps at around 5 C higher than Real Temp.

 

Which app is correct, dunno? :unsure:

The actual temp is really not the problem. Wether it's off by a couple Celsius isn't a big concern. It's the rapid rise for no reason even when CPU load is 0-1% and than it stops when I fiddle around with the USB ports. I just use SIW to see it in action.
