I own two of these and have had them running continuously for about a year now. The only problem I had is with a fan making noise on one of them. This was easily fixed by replacing the fan ( http://amzn.to/2nSMfDK ). I have not had any further problems since. Highly recommended.
Hello my name is juan collazo i bought s 400 about 4 month ago and the fan is making noise, is there any way way i can get a new fan, to replace thanks
Hi Juan,
I had the same issue with mine after I blew the dust away (cleaned it) with compressed air. I now use a vacuum (suction) instead. Fixing it yourself is cheaper than paying for the shipping to send it back to be repaired by the supplier. Click this link ( http://amzn.to/2nSMfDK ) to see the fan I used to replace mine with. I have not had a problem for two years now after the repair. The only difference is that you will need to place the fan on the outside of the power supply.
