Y900 DIY model CPU a bit loud? Any suggestion of replacement?

2016-07-25, 16:44 PM

I found the CPU fan is a bit loud in my opinion, I like a more quiet one. Any recommendation of a quiet CPU fan compatible with this machine?

Solved! See the solution

The Lenovo Y900 gaming series uses industry standard parts. The socket for your computer is LGA1151- so you'll need to find a fan that fits that socket. If you're looking for something really silent, consider a water cooled system. The Y900 allows for water cooling from the top.

Solution:  No need to change parts!

 

Go to BIOS, change the system fan setting from SmartAuto to Manual, set minimum PWM to 10%, the world will be quiet again.

There are three possible solutions to this. 

 

1: Adjust the fan curve. This is what you did. This causes the fan to engage less and thus produce less noise. However, this may cause your CPU temperature to rise (the default curve is the way it is for a reason!). Make sure to benchmark after adjusting your fan settings to ensure that the resulting temperatures are acceptable. RealBench can be used to stress the CPU while you monitor the temperature with HWMonitorThis fix is free, but could reduce performance or CPU life time.

 

2: Change the CPU fan. The mount on the default heatsink is a standard 120 mm mount and thus you can replace it with any 120 mm fan of your choice (or even a 140 mm with a 120 mm mount like this Noctua). A more premium fan could be better at cooling while also being quieter. Larger fans, like a round 140 mm, are quieter than smaller fans (assuming equal quality) while pushing the same amount of air by merit of being able to do so at a lower RPM.

 

Note: if you did this, it would free the CPU fan for some other purpose. The Y900DIY comes with three empty fan mounts and you could relocate the fan to one of these locations. However, the fan would then make noise, which you find undesirable.

 

3: Upgrade to a different cooler. You could replace the stock cooler with a more effective cooling solution that is thus quieter. Higher end air coolers (like this Noctua) can use multiple fans and thus the total fan speed may be lower while maintaining temperatures. Alternatively, liquid coolers (like this Corsair) can use the same fans while being much quieter and/or cooler due to the superior cooling offered by liquid. Coolers tend to come with their own fans and thus your current fans could be re-used elsewhere.

 

I highly advise a liquid cooler! The upfront cost is high (that unit linked is $100), but they are extremely effective: you will either have reduced temperatures or reduced noise and possibly both, depending on how aggressively you overclock.

 

Again, reducing your fan speeds will increase your temperatures and this will reduce the life span of your CPU!

 

If you really want to, you can also install a liquid cooler on your graphics card, thus further reducing noise!

Hi

I noticed the same problem. However when I removed the cpu fan without disconnecting it from the motherboard, when i ran it.it was silent. As soon as I fixed it to the motherboard the droning came back. This meant the sound was due to vibration somewhere on the case. With my particular computer it turned out to be mainly caused by vibration in the plastic front panel and the plastic filter behind it. I used small pieces of bluetack to cushion the adjacent plastic pieces. Surprisingly it worked.

Agree with what HuaZ said. Runs super quiet and still stays plenty cool even under load.
