Martin 0 Posted January 1, 2016 and this : http://community.coolermaster.com/index.php/topic/12563-nepton-280l-rattling-noise-from-pump/?p=117106 Connected pump into system fan and run it at full speed no change, also unscrew abit and again no change, pump is only silent when case is upside down and when i put it upside down it makes swoosh sound for about 10-15min and then completly silent and after back to normal position its rattling again. i will rma it anyway, its my second nepton 240m with same problem definetly poor quality control, in future i will think twice on buying coolermaster product.

If it falls below 1300, it can cause damage to the pump and cause rattling. Share this post Link to post Share on other sites

Pump is running at full speed from day 1 so it never runned that low, lowest was 2200rpm and that was only in bios, after that i set it to full speed again.

luciferuru 0 Posted January 2, 2016 How do you lower it ? If i connect the pump on the cpu_fan or opt, Fan xpert 2 tell me i cant change the speed of my pump. If i put in turbo mode, or other mode, the pump still run at 2700 rpm. I am on an Asus motherboard Share this post Link to post Share on other sites

I am on an Asus motherboard in bios you got PWN mode and DC mode when you select DC mode pump is going down to 2200-2300rpm and fans are going up to 1500rpm temp stays same but even with those rpm i can hear rattling when i go close to the case so definetly RMA again.. really disappointed from this product.. big fail because this is my second and now i need to try 3rd one and if that one is fail too than that will be my last CM product.
