fan making noise, is this normal??

Hey guys my fan on my 7915u kicked in and it started going on and off on and off like from low to med low to med. now its fine but is this unit defective?

 

For lack of a better name its called Pulse cooling and its perfectly normal for the newer FX computers

 

yea i was trying to figure out a name for it couldnt think of a better term lol, just wanted to make sure it was normal lol

 

Yeah its not like the older FX (or most computers) where you would get a constant humm of the fans that would increase as needed. Your fans will be almost dead quite then rev up to med/high RPM's to cool the CPU/GPU and then once thats done (1 second or so) it will drop back down to very low RPMs again.

Not sure if its a better method or not, but the new FX (78xx and after) all seem to use it

 

good. getting mine on Thursday. at least this isn't a problem.

@gselsidi let me call your attention to the hard-disk, just for verifications sake. how is the hard-disk's performance? check out this thread.

Hard drives fail mate, its just the way it is. Its nothing to be overly alarmed about.

Just test out your machine before you load all of your apps on it and you will generally be fine.

 

also sometimes when i turn on the machine i hear an eeeeeeeeeeeeeeeeee sound for a few seconds is that the fan?

 

Yea i read that, what software can i use to test the hard drive? just run the regular windows check for errors?

 

Yes the fan spins fast for a few seconds when you first power on the laptop

 

yea idk i wish this would be like my old 6860 lol

 

on another note the build of the 7915 is so much better, seems more rugid and sturdy, and not to mention its amazing how most of the time just browsing the web ect. the fan doesnt even go on.

 

download the ultimate boot cd from here and run gwscan.
http://ubcd.sourceforge.net/

i'll post my results on that forum once mine arrives on thursday.

 

What did you mean by this? On the same model you think the other one has a better build?

 

yea sorry i forgot to put better build then the 6860fx.

also again when the fan kicks on is it supposed to make a sqeeky eeeeeeeeee noise? like a pin dropping type of noise but constant??

 

Its the same chasis it just has a different graphic

Its might sound like that to you, but it should just be a high RPM "woosh" sound before it drops back down to its low RPM setting (but the fan is still on i promise)

 

yea i hear the woosh thats not the problem i hear this high pitched eeeeeeeeeeeeeee sound too, when it first turns on.

Also the laptop had a minor scratch on the case barley noticable, and what i noticed is you know how on the monitor where those two things are that hold the monitor, and how they have that plastic over them, the left one didn't.

Yea i heard the fan turn on again and i heard the wooosh now i hear the eeeeeeee in the background.

IDK do i think i should get it replaced?

 

Its probably fine, and you just happen to be sensitive to the harmonic that the fan produces.

With out being able to hear it myself though i really cant tell you if it might be the fan being messed up or you just have an easy time hearing the tone it produces.

And while i'm here to be as helpful as i can i'm not driving to your house to listen to a laptop fan
But you might can get a friend to listen to it and see if they can pick up the same noise. That might be able to tell you if its the fan or just your hearing

 

no trust me its def. the fan everytime it turns on you hear the squeeeky eeee in the background everytime it turns off it stops.

 

its the fan on the cpu side, the gpu fan is fine.

 

Keep an eye on temps and keep that noise in mind, perhaps the fan is on it's way out, sounds like the fan might have a bit of resistance. I'm assuming the heatsink vents and fans are clean and free of hair/dust/dirt/etc.
