I have a Microtek 350watts SMPS. From past few days the fan of the SMPS is making noises every morning of boot up. After a couple of hit on the out side it stops. Now when I contacted my hardware vendor I found out that the warranty is over. Now I am thinking whether I should repair it or wait it till it stops working completely, & then buy a new SMPS. Another thing is, is it safe to work with a faulty SMPS fan. If I have to buy a new one then for an average use (AMD 2600, 2 optical drive, 80GB, planning to buy a grfx card) which company & model I should opt for? What will be the pries?
