A hard lockup - Page 3

I have used JB Weld in the past to attach a fan to a heatsink that wasn't designed to have a fan.

Super glue would probably work, too.

My guess would be that since a fan on the heatsink is working, then you probably have good thermal contact between the chip and heatsink. If the thermal paste was a big issue, then even a fan on the heatsink wouldn't help that much.

Another idea for direct air flow:

See this thread. http://forums.fedoraforum.org/showth...21#post1593321 (But give me a minute or two to get the photos up.)

Something is almost as hot as the sun.

Have you already tried to run a 'sensors-detect'?

I'd not discount an HD issue - perhaps involving grub sections ... sure sounds like a corrupt something. What throws me is it affects all the other OSs (except Win). Hmm. I think I still would vote heat though.

@marvin_ita. Regarding sensors-detect. Yes, several times. Doesn't find much of anything.
@lightman47. It's heat. The fan seems to have solved the issue.
@dbelton. Good point re: the fan is working so thermal paste is probably not the issue. That didn't occur to me.

It has been 20 days since I started this thread. From the time I set the small cooling fan on top of the GPU heatsink (18-19 days ago) there have been no lockups or reboots. Solved. The issue was definitely heat related. Now to jury rig that fan so's I can upright the computer and put the cover back on the side of the thing.

Thanks for all the replies and the interest.

Think this would hold that fan on your heatsink?

Dang.

Belton got there first. <..

Well, if you're gonna do sumthin.. Do it right.. or at least do it big.

Real funny. The best laugh would be provided by a picture of my final "attach the fan to the heat sink" solution. All it took was one zip tie.

I actually super-glued the fan to the 'sink first but that resulted in some audible vibration. Not acceptable.

***DBelton*** · #41 28th July 2012, 03:35 PM

Zip ties should be in every home.. Right beside the duct tape

Bought a tube of 1000 cheapos for $10 years ago. They're indespensible in my opinion.

I'm getting the same problem with a hard lockup. Random crashes aometimes with a message that one core is not in sync so I'm gressing it might be more serious and a new machine as well. I inititially thought on-board graphics but tried F17,F16,F15, Linux Mint and all the same result. Now using Nvidia GT520 and nouveau. Same.
My system:
F15 in Fallback mode.
Abit MB
Intel Duo Core G530 @ 2.4 Ghz
Sandybridge Series 6 / C200 series
Current Graphics Nvidia GT520 PCIe
RAM 2 Gb
Temperature on both cores never reaches 50C so not a temperature problem.
I'll try the Memtest and see if it is RAM
I'm running Linux Mint on my other two machines with no problems so I may switch one back to F17 and see if it's software or not.

Have you tried running memtest on your system?

***glennzo*** · #45 31st July 2012, 08:40 AM

I do have to say that although I *thought* my problem was solved, it may not have been GPU heat after all. That heat sink was extremely hot and the fan made a huge difference. The system had been stable for days after the addition of the fan. But Sunday last I did a fresh install of Fedora 17 to one of the partitions on the suspect desktop. At a point where the install was complete and I was tweaking things I figured it was time to do the first real complete yum update. It was during that update that something went wrong, very similar to what had been happening in the past. The screen became garbled as in my screen shot. I could tell through the mist that yum was still working. I let it complete and typed reboot. Things have been fine since. Maybe in this case it was the 3.3.4-5 kernel provided as part of the installation? Merely speculation on my part. The heat sink, when the problem occurred, was cool to the touch.
