View Full Version : G751 Whining Fans?

11-26-2014, 08:39 PM
So, when I got the G751 I found it had a little bit of a higher pitched whining sound to the fan and then it got louder so I sent it in and they replaced a fan (don't know whether it was the right one or not) and initially I thought there was an improvement but that only lasted a few hours and the problem still happens. Sometimes it doesn't happen for hours, which is strange. Anyway, I just want to know whether to pursue it or whether it's just normal and I have to force my brain to find a way to deal with it. Do other G751 owners notice a high pitched sound like a wind passing through a reed (or a super quiet chainsaw) which comes and goes (mostly when the fan is on a low setting, just above idle)? I'm trying very hard not to take a hatchet to this otherwise wonderful computer, but it is hard to concentrate when I am working. Also, if anyone bought their computer from Prostar and had the additional copper heat sinks installed to improve cooling I would like to know how their fans sound because I was wondering whether that could have changed the shape of the air pathway or something. I see youtubes with fan noise tests where they always sounds perfect, but I've never seen an actual working model apart from my own, so I would like to know how other people's fans sound. Thanks.

if you have a high pitched whining like a reed then clearly this is not normal... return it again or make double sure it isnt some kind of capacitor squeal.

My fans are a dull whoosh.

I experienced the same with my G751JY.. It's been shipped off to RMA yesterday.

I had several things that needed a fix - But this sound was driving me crazy and it shouldn't be making it!

Thanks for your help. I'll try to get it fixed then.

Yeah, ive got the exact same problem since a couple weeks ago, left fan, funny noise, and exactl as a "little chainsaw thing, specially on iddle", temps are good, right fan is good, maybe some more information on the issue?
