I bought a DDC from coolercases a few weeks ago. Its been installed for two days, and was working fine but I go to switch on the pc and the pump doesnt want to start anymore. Any ideas what could be wrong with it? I havent drained the system yet, Im hoping I wont need to becuase it will take a few hours..
This occationally happens with one of my pumps. Hitting it does indeed start it. But also disconnecting and reconnecting the power one or a couple times does as well. I was planning on installing a switch on the back of my case so I can easily reset the pump in these rare cases.
when i was testing mine (hooked it up on its own with the res) it would do that, but never done it since, when in the full system very odd, thought it was broken at first...
This is a rare, but not unknown problem with the DCC pump. On Procooling.com there have been several mentions of this, one by cetoole here: http://forums.procooling.com/vbb/showthread.php?p=134533&highlight=problems#post134533 ...and also here: http://forums.procooling.com/vbb/showthread.php?t=11745 ...and elsewhere on the internet: http://forums.silentpcreview.com/viewtopic.php?t=19605 ...on that forum, eander315 states: If you have a pump with serial no: 3166546 or higher you should be OK. If not, RMA asap.
Thanks for the replys. The pump worked after hitting it a few times and it seems it might need hitting every time its turned on.. so I *might* send it back for refund.. dunno yet. Im very supprised as to not hear of this problem before (As its quite a major fault in the pump...). Ive not seen any threads either here or proforums about it before (usually the problem has been posted in existing threads so no threads have a name indicating a problem..). The pump serial number is 3225***. Ive read all I can find about the problem and it seems that the later serial numbers have exactlty the same problem and it occurs just as often. I think the only things they changed were: Currentlimit removed - so it can get slightly more power at startup Voltage limit removed - theprogrammed it not to start if it was higher than 13.3v People say it could be either of these things, and theres lots of other things it could be: Not enoough torque on startup if the rotor stops at certian positions or not enough lubrication for the bearings - so coolant mix could have an effect. Any air bubbles in the water. So Im going to try the pump at 9v, that should stop any air bubbles (at 12v there is a few - res not good enough air trap) Also could try at 13v, to see if the power will help it start.
