Nitemare3219 Posted October 25, 2013 Share Posted October 25, 2013 I'm not sure if this is relevant to the stickied thread or not about this, and I'd figured it'd have been resolved with the H100i units. I purchased this unit about 3 weeks ago from Microcenter, so I'm not sure how long it was sitting on the shelf. Lot code is 13199434. Basically, at boot (usually cold boots) the pump will make a loud grinding noise (not the fans) and it gets worse as the RPM drops from 600 to 500. Once it gets there, it bumps up to 2200~ and is fine. My PSU is an Antec CP-850 with 12.288v on the rails. I do recall seeing it even hit 12.312v at times, usually around boot is when it fluctuated if I remember correct. Anyway, this is probably why it's happening. The pump has never done this once the unit is at normal operation. My question is, would it be a good idea to proceed with an RMA? Or is it likely this is just going to happen again... because I thought this issue was fixed and would hate to mess with it if the same result will occur. I submitted a ticket, but they just gave me a really generic answer. The noise doesn't bother me so much as it worries me something may go wrong later.
