Corsair SF450 spinning at idle
Posted: Mon Jun 13, 2016 8:58 am
Hey everyone.
I have just put my new build together and everything seems to be running fine. I went with the Corsair SF450 as my psu.
Here are just a few words about my experience so far:
I have to say I love the smaller form-factor of the sfx standard. It really frees up a lot of space in the case. The case I used for this build is the Ncase M1 and I definitely feel the case is designed with sfx psu in mind although certainly an ATX psu is also an option.
One of the reason I went with the SF450 was because of its ability to be fanless at lower loads. However in my case the fan seems to be spinning even at idle. Although it is spinning very slowly, this is exactly what I was trying to avoid by choosing this psu. Otherwise the psu looks and works great. There is a little bit of rattling also at low speed, but it is very very faint and my computer is very close to where I am sitting. I cannot hear it from where I am sitting however someone with a quieter system might. Under load it seems to spin up a bit, but I have not done enough testing to really say anything useful here. Other than that it seems to be a unit of good quality and it feels solid in hand.
I have checked that the cpu is downclocking correctly to 800mhz (i5 6600k) when idle so it should be fairly efficient. Other than that I have the GTX 750ti and 1 sdd along with 1 3.5" hdd installed.
So what do you guys think, is this to be considered normal? The fan of the psu is facing outwards, but I have my doubts that the orientation of the case will be of importance in my case. I am still considering going with a fanless atx psu, however this will mean some compromises elsewhere.
Edit: Just tested powerdraw from the wall with Kill-a-watt. It seems to be idling at around 40W. With light use it probably increases a little bit.
