9560 Reliability / Longevity from Fans Always On

About 10 days into 9560 ownership. My main concern at this point is that the fan is always spinning at 2500 when I'm connected to my 3440x1440 monitor and A/C plugged in (I use the laptop mostly connected like this at my desk). Seems like this is just the way it's designed. On battery and w/o external display the fans will be off under normal/light load. Noise isn't an issue (still pretty quiet). But will the always on fan be a reliability issue? Will fans crap out in a year? Debating if I should keep it.

 

I keep my fans on the MBP running 24/7 and when I'm rendering or encoding I manually set them to Max ...the computer stays on 24/7 and my other mid 2102 fully maxed MBP has less days "off" than triple digits...On my AW's I keep the fans on max all the time...never had an issue with the fans going out and if it ever did on the XPS, it can be swapped out in literally less than 5 minutes tops.

 

My sister had an old Asus laptop that she used from 2009 till 2015 - the fan never had an issue even tho it was on constantly - you're good. Most fans live upwards of 100 000 hours.

 

3 fan swaps in 18 months on my 9530 so go figure it is the usual cheaped out parts.

 

I have a 13 XPS13 from 2015 that I might have used 200 hours maximum and the fans om that sounds like a tractor these days. That said, it did experience kind of a free fall a few months back so could be due to that also.

Yikes...good thing they are cheap and better yet, super easy to swap out.

BTW, what are yall using to keep the fans on Max? hwinfo64 has yet to support the new kaby lake XPS 15.

 

No, you don't have a reliability issue simply because a fan is running all the time. As other have said, it is not uncommon to have a small computer fan rated for 100,000's of hours of duty cycle (to give you a sense of scale, there are 8760 hours in a year. It would take 11 straight years to hit the first 100,000 hour mark).

It's not unheard of for the fan to run in your described scenario. Outputting to 1440p-ultrawide puts strain on the GPU (especially if your main laptop screen is also on at the same time), generating heat. Charging the battery also generates heat. And this is just at CPU idle. If your CPU is doing any kind of processing, that is even more heat. Those small amounts of heat can add up in a thin chassis like what XPS 15 has.

Besides, fans are relatively cheap and easy to replace. I'd much rather burn out and replace a $15 fan, rather than preserve the fan at the expense of other components burning out early from heat (most likely your $80+ battery wearing out faster than it should; less likely a major component would die, like your CPU or $400+ motherboard).

The only downside of keeping a fan running all the time is the noise. If I could, I would run every fan in every computer I owned all the time. So I wouldn't worry about your situation. A running fan is a good thing.

wonder how much just having a spare set around would be....might not be a bad idea...

 

Speedfan can do it but you can also select the cool profile to make the fans work harder.

I think I found the identicals on aliexpress for the 9530 and they came in about £35 a pair.

 

I've tried using Dell Command Power Manager, but it's not as aggressive as I want it to be. (Thanks to @DeeX for bringing that app to my attention.)

Do you have a link to the Speedfan version you are using?

Thanks.

 

That is relatively low rpm. I would not worry about it. Running cheap fans constantly at 5000 rpm will show early wear.

I try to keep my work area dust free. And open the laptop every so often to clean the fans as dust build-up on the blades will accelerate fan bearing wear. Sometimes, when laptop fans get noisy, I try an early intervention (disassemble, relubricate and reuse for a few years); not always possible.

 

No as I don't use it. Have before so get the latest I guess.

 

Easy enough. Thanks.
