mikee2185 Posted October 6, 2010 Share Posted October 6, 2010 I got AX1200 too yesterday, and it works, no buzzing noise issue here, but heck, the fan is like airplane turbine! When i start the PSU using wires, with ambient temp 23°C, its looks like running on full rpm, and it makes much more noise then my old Xilence 600W at near of capacity. I would not care if the PSU fan will spin up when temp goes up under heavy load, but right now my setup takes only fragment of its capacity on full load, and almost nothing at idle. I even tried to stick a piece of cloth into fan to force it stop, and when its outside case, i got him after 1h of playing at 30°C.. so WHY it spins its fan like mad? if it would run at 600rpm with low temperatures, it would be cool&quiet, with no reduced lifetime :( Is there a way there can be faulty sensor, or is there a way to force it go on lower rpm? I dont wanna open brand new (and expensive) PSU just to put thermistor before fan.. Also, funny thing (which makes me think it really runs on highest rpm): Normally, the motor of fan makes quiet noise itself (not just airflow), but when i cover about third of intake, its much qieter (only air makes noise). So no i can't decide, return this psu or not? It would be shame, i waited a long time to store get it for me (for some reason it wasn't available in CZE), and its other characteristics are awesome.. Important note: I have WaterCooled system, so the only other noise comes for low-rpm fans in case and radiator, but those i can't hear till i put head next to them... So its definitelty PSU (and as mentioned at beginning, i tried it alone too). Second note: I'm planning system upgrade, thats why so strong psu..
