Noisy Fans

I keep replacing cooling fans on both the case and the power supply due to noise. I've tried different manufacturers, Quiet PC and Cool master but each one gets noisey again after 6 months. Anyone had the same problem and is there really a fan which gives better service.

Presumeably you're referring to bearing noise rather than blade noise. Blade noise is affected by the profile and speed of the blade. The way to minimise this is by using a large diameter low speed fan. Both power supplies and processor heatsinks are available with these. If the bearings are wearing quickly, then either you are using poor quality fans or they are working in a particularly hostile environment.

Try lifting the label in middle of fan and put one spot of oil in the centre.

As I said using fans from Quiet PC and Coolmaster, both supposed to be reputable companies with good products and yes it is the noise from the bearingson the power supply and case fans.Power supply from QuietPC approx 18 months old, case fan coolmaster less than a year. Tried the oil routine Woodchip works for a week then noisey again. Any better companies to try? Is ball bearing better than tube?

Things to consider.

Do you have pets. Pets shed lots of hair. This gets sucked into the Fans.

Do you Smoke. Fag smoke it sticky. It makes dust stick to the fan.

Do you have the PC on the floor. Dust sinks, and the floor is as low as it can sink.

Do you/family member have long hair. We all shed hair, just like out pets.

Regardless of the quality of the fan, and it's bearings, if the fan blades get coated in goo, the goo will not deposit it self evenly, and will unbalance the fan. The will not only make the fan noisy, (as the fan vibrats, because it is not balanced), but will impose extra load on the bearing, and cause the beairng to wear out faster.
