How do i know that my pump is getting 12v? Are all the molex connections delivering whatever the device connected to them wants? or is it more like each one is either 3v,5v, or 12v,? The former seems more likely.

My temps, for no good reason are out of control lately. Browsing gets me up into the 80s (C) wherease before, i was chillin in the 40s.

i'm planning on redoing the loop and even getting a nice eheim to replace my mpc500 or whatever swiftech throws at you..but like, any insight would do wonders.

oh, i suspect the pump cause well, it's not making as much noise as it used to. i got it last november.
 
Hard drive power connecters have two ground lines (black), one five volt line (red), and one 12 volt line (yellow). They are set up so that you can't mess things up unless you really try.

Is the pump pumping at all?
 
looks a lot like pump failure to me. no way you could shoot that high overnight unless you have a serious problem with your flow. check to make sure it's still plugged in. then check to make sure it still pushes water. even slow moving water won't get that hot.
 
When the machine turns on, you see water moving for an instant, cause it's getting it's flow on. Otherwise, the temps begin at a high 49 degrees and then get hotter. i was playing agame and the 85 degree alarm went off! Like, that's why I posted in the first place..i was just kinda shocked that the pump would die so quickly.

I'm gonna take the cooling loop out of the case and try air cooling for a bit. i'll do some tests on the loop to see if in fact water's being moved, look for a blockage, that kinda thing.


weirdest thing though, i put my hand to the back of the machine where the rad exhaust flows...the air comingout of hte rad was coool....so yah, the whole thing's shot. looks like getting the retail version of the chip was good, i'll use the stock cooler until i can sort things out.

Damn, i hate having to disconnect everything in the back....
