Temperature Spike of Unknown Cause

[A-Speck]

So about 15 minutes ago, I was cruising the forums, when all of a sudden my comp's temperature alarm came on. I immediately checked the temps, and I was at 89 degrees C. I immediately cut the power, then started checking my connections to make sure my fans were powered and my pump was running. No problems there. After giving it a while to cool down, I started her up again and went into the BIOS. Temps were holding steady at 44 C, so I went ahead and went back into Windows. No problems since. From the suddenness of the spike, it sounds almost like my pump just quit doing its job, but it's a brand new Swifty MCP600, and it's working fine now. I'm definitely keeping an eye on the temperature now, though.

Anyone have any ideas?

a big airbubble maybe??

I've got plenty of extra water in my T-line, so I don't know how an airbubble would get into the line.

How would a big airbubble cause a big temperature spike like that, anyway?

Your temperature monitor probably just malfuntioned for a second or two. Did you touch your waterblock right after you cut the power to see how hot it was? I have one thermal monitor on my computer that jumps sometimes, I am pretty sure it is because my rails aren't close enough to spec and just goes a little wacko. Like all the way up to 79ºC down to -52ºC. Though it doesn't happen very often. I would say something like a rail just jumped for a second and it reported an incorrect temp.

I actually booted it up about a minute after it turned off, but the temperature warning buzzer started right up again, so I turned it back off. That probably means the temperature monitor wasn't on the fritz, I guess. I've actually never overheated a system before this.

Hmmm. Now the pump is making strange creaky noises every once in a while.

Possible the pump died for a sec? Or a bubble in the pump and now some air is in it?

[ralf_c]

its possible that the molex connection failed, try moving the pump cables a bit to see if the pump stops.

How long have you run this computer?
I would run with case off and feel water block and see if it hot

My geuss is that the pump is dying, or you got a bad connection.

[A-Speck]

Just an update, here. My pump died on me. Out of all the brand new Swifty pumps out there, I had to get a bum one. I'm RMAing it, should have a new one by next week.

Was your first pump the revision 1 or revision 2 series?

[A-Speck]

When I called Swiftech, the guy had me look at the serial number. It started with an "S," which I believe means it's of the newer rev.
