abit kt7 fan grinding/stopping problem

[plebeian]

OK, not the most descriptive of titles but...

My friend has an abit kt7. The fan on the Northbridge (?) chip is acting strange. It pulses on and off, comming to a complete stop every couple seconds, and producing a grinding/droning noise. In and of itself this wouldn't strike me as a problem, since I don't think that active cooling is too necessary on that part. (This is a 800 T-bird/ PC133 system.)

However, this behavior is coupled with a performance issue, namely the mouse is intermitently jerky/freezing for a short period (0.5-1.0 sec). Do these sound at all related?

Is the mouse jerkiness a SW or operating system problem? (We've tried several mice- they act the same.)

Is this a motherboard problem? CPU? Power supply?

Any SWAGs from the esteemed members of this board would be appreciated. Thanks.

That's really odd. You're right, active cooling is more of a luxury on the Northbridge than anything else... but how this relates to your mouse, I have no idea. The only thing I can think of is a power issue, because weird problems like this can be caused by a flaky PS.

Well,

If that particular MB is flaky to begin with (you know, barely passes QC), then the FAN may be the difference between a stable and a not-so-stable system. And the mouse could be acting up because of this.

Drop by your local computer shop and pick up a new 2-pin fan and replace that one. It certainly cannot hurt, and it may very well improve stability/performance!!

G/L either way,

the Northbridge should be fine, especially with it being KT7. most manufactureors don't even put a fan there. but edblor's right, just get a cheap fan and try. it can't hurt getting a better fan.
