HW monitor says zero revs on cpu cooler

Hello. I´m using HW Monitor for watching my rig. Athlon II X2 250, Arctic Freezer 64, Gigabyte GA-MA 770 UD3. Clocked to 3.6 GHz core, 2160 MHz on NB and HT link.

The sytem runs nice and cool in my Antec case, 23/33 C idle/load oon cpu, so I really don´t think there´s anything wrong.

But from time to time, a couple of times a day maybe, I can see, that the speed of the cpu HSF value reads "0" in the min. tab.

When I first saw it, I stared at HWM till my eyes were square, and after a long wait I saw the fan apparantly stopped for maybe a second and then immidiately returned to 500 rpm again as if it never happened. And now I have seen it for the other fan i have on the other side of the HS for pull as well: down to stop for about a second or so, and then back to normal.

Both are attached to the mobo with three-pin headers.

If it is the powersupply or the mobo, I should fix it before something happens while I play. But if it somehow is something with a sensor or the software, everything is fine.

Have anyone had similar experiences?

    I'd be inclined to check the reading in the BIOS first as this eliminates the possibility that the software you're using is giving a false reading.
  2. Yeah, you´re right, I´l try just that. A bit boring though... :)

    Thanks for answering.
  3. Øhmm, by the way, I´m new to this forum - and forums in general.

    Is there a kind of pointsystem, where it is considered polite to give points to the people who take the time to answer?
  4. Well try that and see what happens; if you have any more trouble post back. Tom's does have a points system yeah, I think as the original poster you can elect a 'best-answer' to your problem and that awards points to the user of your choice.
  5. Ok, thanks moody89.

    I seem to remember I saw a screenshot of HWM in some review somewhere sometime, that looked similar, but I really didn´t pay attention to it then, so I´m not really sure anyway. Maybe I can find it again


    It happened once since last reply, so I´d better check out what´s happening,


    And a handful of points coming right up...
