andreaz70 Posted February 14, 2013 Share Posted February 14, 2013 Hello All! Im a proud owner of 2 of the H100i Coolers. The one with Firmware 1.0.4 seems to work good, except a lil whine from the fans on some rpm. The other one got Firmware 1.0.5 but still the "not-pwm" fans. And here i got a random "click, click"-noise and can't verify from where it comes. When i pull the Cable from the Pump (the Y Cable for the fans), it seems to be gone. Could it be its coming from the fans? Is it possible to exchange all 4 fans to the new pwm ones in one rma request to lower shipping costs? Is it also possible to get the new fans, before i send out the old ones? I suspect the fans for the click-noise, cause it seems to be there when the rpm is changing....

Toasted Posted February 15, 2013 Share Posted February 15, 2013 Request an RMA and explain your issue. Customer service should send you instructions for the PWM fans. Link to comment Share on other sites More sharing options...
Speed Posted February 15, 2013 Share Posted February 15, 2013 And here i got a random "click, click"-noise and can't verify from where it comes. Use what is known as a "poor man's stethoscope". Find a long, thin rod, (screwdriver or similar) long enough to comfortably reach into the case.Ground yourself before doing this, so that you do not transmit any static charge to the equipment.Be very careful to not touch any surrounding components. I have a set of electrician's screwdrivers that are insulated all along the length of the blade to prevent this occurrence. Better yet, a simple wood dowel will work.Gently touch non-conductive areas of components that you suspect are making noise with the far end of the rod. Place the near end against your ear.The sound will be localized by conduction and will become readily apparent as to which component is making what noise, if any. This works so well that we use it on running racing engines to check the condition of bearings. Link to comment Share on other sites More sharing options...
andreaz70 Posted February 28, 2013 Author Share Posted February 28, 2013 Hehehe... Great Idea. I know that also from hearing into engines. Never adopt that to any other components. But in the meantime i realized where it come from. The fans are clicking (not pwm), when they change their rpm. Need to confirm this again, after i put in the replacement fans (pwm). But anyway, thanks for this lovely idea.. :) Andreas Link to comment Share on other sites More sharing options...
