i have just purchased a new cooler master 210 plus. the heatsink is great, and it cools my cpu down to about 30C. lately i turned down the rpm's on the cpu fan because it was making too much noise, turned down to 750rpm from 2000. the cpu still runs very well at 35-40C, but lately i noticed that there is a fairly loud clicking repetitious sound coming from the heatsink fan at 750rpm. so is there a way to fix this? it seems that when the fan runs at full or close to full speed, it eliminates the problem, but as soon as the i lower the speed to reduce the sound, i get a clicking sound. as compared to my case fans, they are the same size as the heatsink one (120mm), and dont make nearly as much sound
how would you say i could "balance it?" when i do run at higher rpm, the fan sound is just louder than the clicking, thats why you cant hear it. but the fan does seem to be shaking a bit when working ( the blades). any ideas?
