Liquid Coolers

So Himawari is equipped with an Antec Kuler H2O 950, which since I built it has been working splendidly.

Obviously this is no longer the case, or I wouldn't be writing this. And so I'm asking for help.

Basically every once in a while, especially when playing World of Tanks, I get what I'm calling a Thermal Runaway. The LED over the contact plate goes from Green, through Yellow, Orange, and Red in a matter of about 30 seconds while the fan goes into high gear. But nothing seems to stop the inevitable overheat shutdown.

Even exiting all the programs, so the processor load is 0%, it still goes into shutdown.

Once I was able to get it to sleep before it shut down, and it woke up almost immediately cooler, but typically if it shuts down, it stays hot for 5-10 minutes and won't finish booting before it snaps off again.

But it's not entirely predictable. I can play a dozen battles without getting above 45C (Motherboard readout). The last time I was just looking at a web page. It's not making any weird noises, and it hasn't leaked. so it appears to be working normally until this happens.

Any suggestions?

1 Pump is going bad, apparently. Mechanic's stethoscope confirmed it. Fortunately I still have my receipt from building the machine in 2013, and I think they might be replacing it for me. (Waiting on a reply to sending a scan of the receipt as proof of purchase).

2 And now that I've put down the deposit on the advance replacement, it's been behaving itself all weekend. (After a slight yank in the effort to get the pump to kick in again on Friday.)

But as all programmers know, problems that go away by themselves come back by themselves. So I'm not going to call off the swap.

3 New cooler installed, we shall see how it works....

4 Works very well, after install, I ran a 24 hour torture test using AMD's official unofficial overclocking tool. (Also went to 4.2 Ghz until certain programs proved not to like that). Now I have to get around to shipping the defective one back to get my $100 back. It's already been a week.

5 So of course, what happens next? The hard drive goes spotty and won't boot. Just like last time. I can't win. (And even worse, I ended up overwriting a lot of my backup with the older backup. Argh!). I just LOVE re-building my windows system from scratch every year....

One lesson learned though, Seagate: Never Again.

6 So, no more screwing around, I went to Fry's and bought two new Western Digital Red's, at 3 TB each, to dedicate to backups, and I'll make sure to have a bootable clone of my C: drive.

If I'm lucky, I'll even be able to keep the up to date.

(NAS units are a bit too expensive at this point in time, however.)

7 And Windows Backup fails with anything larger than 2 TB. Way to keep up with the times, Microsoft.  Gonna have to try third party backup software.
