77 degrees Celsius AMD CPU overheat issue !! Need input! - Page 2

post #11 of 14
Make sure your pump is actually running, I had the same kit and the pump failed after 1 month of use. My CPU was throttling at 105C.

So I've been running an AMD Phenom 955BE cooled by an XSPC rasa 750 RS360 kit (everything's still stock) for almost 2 years now. It's overclocked to 4.3Ghz from 3.2. I monitored the temps for over 4 months after I OCed it, and the temps never exceeded 62C, so I figured I'd let it run without supervision after that.

Well recently (in the past two weeks or so), my computer started crashing, like once every 30 mins when under load. So I opened up coretemp, and saw my CPU was at a whopping 77C !! Yes, that's seventy-seven degrees celsius - 12 degrees over the manufacturer's Max operating temp. That's [obviously] insane.

I immediately shut it down, emptied the coolant in my WC loop, rinsed the loop with hot water for 30 mins, then refilled it with fresh distilled water.... Which ended up decreasing the temps 2C........

I honestly don't really know what to do now.. I'm typing this on this very computer, in which I reset all AI tweaking settings back to factory, so 3.2Ghz @ 1.56v (I think). Not really sure if in reality, the CPU was running way overheat for an extended period of time, which quickly degraded it, and now, it's considered somewhat "fried"... or maybe there's something I'm completely missing to do with my WC loop? Now that I said that, it leads me to think I've forgotten something to do with my watercooling loop to maintain it..?!

More general info on my loop:
-As said earlier, everything I have is what came with the rasa kit
-The order is res>CPU block>rad>res
-Last time I remounted the waterblock was around November sometime I think.
-Running distilled water (Last time changed was 4 days ago)
-Killcoil
-6 120mm fans in push/pull all moving cool air from above the case into the case.
-3 fans are what came with the rasa kit, 3 are super-slim scythe 120mm fans.

I don't really know.. anyways, if you're reading this, thanks for reading everything above..

Here's the guts:

Thanks in advance, I really appreciate it.


Perhaps your waterblock is gunking up.

This is what the inside of the XSPC Rasa looks like

It is really easy for waterblocks with that design to gunk up, and when they gunk up the lose all their surface area thus making them very poor heatsinks tongue.gif

I would disassemble your waterblock and see if it's all gunked up.
