skyboyextreme Posted October 2, 2013 Share Posted October 2, 2013 hey i'm from egypt, i bought this H100i at a local retail store last month the problem with it is majority of time on cold boot the pump RPM is quit low @ 700 ~ 800 RPM and when this happens the pump makes a loud crunching noise but sometimes after a few restarts the pump RPM becomes 2000 ~ 2200 and the noise is all gone .... it's not fan noise it's the pump as i've double checked without the fans even connected at all .... this is totally random sometimes it just works @ 2200 RPM which is silent but other majority of time it runs 700 RPM and make crunching sounds !! is there a fix for this ? what controls the pump RPM ? is RMA my only way ? i'm afraid that retail store will not return it and will give me a headache trying to get a replacement .... i'm on 1.07 firmware i have seen other people having the exact same issue as mine .... please advise !!
