Hey nastynas11

 

Currently there are no BIOS updates for the Lenovo Y700 as I am looking for one too but hopefully withina  few weeks support will release a BIOS update, and fixing the laptop going to sleep and waking problem (for me at least).

 

 

*Also make sure you have set the right parameters for NVIDIA control... so it isnt only using your GPU for internert browsing and other low tasks

yeah i dont know, my fans are generally very quiet unless playing games or doing cpu intense tasks.

 

I'd install iXTU and instead of just monitoring tempeartures, check the options on the graph for monitoring CPU % usage, CPU frequency, and Temperature. Then set the graph over a 5 minute period. Go back to using your laptop like normal and see if an increase in cpu usage/increase in cpu frequency triggered the temp to go up for a bit when your fans kicked in hard.  Make sure you start recording before you have the fan problem so you can see what's triggering the loudness on the graph.

 

If you see higher cpu frequency or cpu usage when the fan noise starts, monitor how it changes and what the temps are and see if everything ever returns to baseline (not just the temperture) so you know if the fans have a reason to keep running.

 

If it turns out that your cpu usage or frequency is increased and remains increased and that's whats triggering the fans, then you should start looking at the programs running and watch their cpu usage using task manager.

I have the same issue with my Y700 15 ISK.

 

Fans randomly speed up at the slightest bit of work for the CPU and often do not slow down again until I restart the system. And even if they are now blasting at full speed there is an almost constant humming sound that is quite irritating.

I just had a thought. You could probably reduce the amount of times this happens by going into the power settings for whatever active plan you're using. Scrolling down to cpu  and expanding that section. Then click the cooling button. Switch it to passive from active when plugged in. This might help. But if you need to use your pc for some gaming or rendering scenes then switch the power plan to high performance till you're done and then switch back. 

 

If there are certain times you need the laptop running as quietly as possible (or even longer battery life), you could create your own power plan, optimize it for battery life and also reduce the cpu max performance from 100% to like 99% or even lower. You should be able to bring it down to about 60% without noticing any slow down in any regular tasks like office, browsing the web, etc. Don't forget to change iGPU performance to be optimized for battery life when not plugged in, or even plugged in if you want to squeeze out that extra bit of silence.

 

Then, when you're done being in a quiet environment or need the horsepower, just switch to the standard plan from the task bar. I use this during classes and it does net me more battery life. 

 

There are plenty of guides online and you can mix and match settings to whatever need suits you. Just do a quick google search for the option to learn more about it.

 

 

Additionally, because i don't know how sensitive you are to the laptop sound, i don't know if your laptop is louder than mine, or if its just more noticible to you. If you feel that your laptop is particularly loud or glitching out, i highly recommend you send it to lenovo for testing. I'm sure they will understand and should not cost you anything. I don't believe lenovo can do anything to repair the issue without your laptop in hand because if it was a software problem, all of us would be experiencing the same problem.

 

 

Adendum: I'm not a professional but if you want to troubleshoot this further online, i recommend getting a free program to graph your CPU ussage, CPU frequency, cores used, AND temperature simultaneously over time. Note when the fans start to speed up and see if anything changed in the graph at the same time. IF the fans never slow down again and the graph returns to baseline as before the fans turned on, then you can draw some pretty good conclusions about the problem.

Same here. Received today and immediatly at the startup of the system it sounded like a whole datacenter in a small laptop. Pretty annoying as it is constant. Called support, but not much help. Pretty expensive laptop as well.

What do you mean not much help, you should insist that they take it back and fix it or replace it. Clearly, you have a hardware issue. Don't take no for an answer.
