Changing Psu Fan

sgt_gaz · Feb 16, 2014

Hello People

My 9 months old Corsair Vs550 is making noise: "Brrrrrrrrrrr" Can you give me an advice for a quiet fan?

ModernWarfare · Feb 16, 2014

I will start by saying I have not taken apart a PC PSU but I have taken apart other high ampage PSU's. If the components are exposed while changing the fan please be very careful, the capacitors can hold huge voltages.

Check the spec of the faulty fan using the part code.

Make sure you get a similar spec fan or even try and get an identical fan as that fan will have been used for a reason.

Changing the fan is usually pretty straight forward but be careful when taking the case apart, don't disturb anything you don't need to.

Thanks
How can i avoid from high voltage? I heard pressing on/off button for 5 secs discharges static electricity. What if i use plastic gloves?

ModernWarfare · Feb 16, 2014

yea be careful dont want to damage anything

ModernWarfare :

Thanks i am thinking about this fan: http://www.amazon.co.uk/Cooler-Master-120-Clear-Frame/dp/B005516OOA
Very good on reviews.

ModernWarfare · Feb 16, 2014

yes thats a good fan good airflow and silent operation. and decent led's that should be fine good luck

ModernWarfare :

Ok but i read that the fan inside Vs550 is "thermally controlled". What does this mean, should i buy a with 4 pins?

ModernWarfare · Feb 16, 2014

no it should only use 3 pins it will power just fine

You can't just use any fan you find.

If the fan you buy has too high of a starting voltage your PSU may overheat before the fan even begins to spin.

If the fan you buy has insufficient airflow you will also risk PSU overheat.

You're trying to replace a Yate Loon D12SM-12 sleeve bearing fan. It's a two wire fan rated at 70.5 CFM @ 1,650 RPM and has a starting voltage of 2.9 Volts.

ModernWarfare :

This, the PSU fan could also be broken

beanoslim · Feb 17, 2014

If ko888's fan spec is right (which I'm sure it is

) you are after one of these http://www.amazon.co.uk/Yate-Loon-Ventilateur-D12SM-12-Black/dp/B003DNLO4M

I would always go like for like with psu fans.

You could try contacting Corsair for a replacement if its faulty.

beanoslim · Feb 17, 2014

Just a thought, you could try pealing the sticker on the fan back and seeing if there is an opening that you could dribble a few drips of oil into, that might quiet it down also.

ko888 :

Thanks a lot! But i can't find a fan with low starting voltage :??:

beanoslim :

Thanks, first i will try oiling the fan .

ko888 · Feb 17, 2014

I'd recommend replacing it with the ball bearing equivalent of that fan since it will have a longer operating life than the sleeve bearing.

ko888 :

What does "thermally controlled" means? Does the psu control fans by changing the voltage like a fan controller?

I can't find Yateloon fans in my country. I'm thinking one of those :
http://www.newegg.com/Product/Product.aspx?Item=N82E16835186033
They are quiet on low rpm and have low starting voltage (3,6).

ko888 · Feb 17, 2014

sgt_gaz :

Thermally controlled means that there is a thermistor mounted usually on the secondary side heatsink that determines what voltage level is provided to the cooling fan.

If the PSU is still within Corsair's 3 year warranty period you can always initiate an RMA and get the PSU replaced as long as you haven't broken the warranty seal affixed to the PSU.

sgt_gaz · Feb 18, 2014

I oiled the fan, it's still noisy. Do you suggest Arctic cooling f12 rpm?

beanoslim · Feb 18, 2014

I'd suggest contacting Corsair and asking them to send u a replacement.
