Core i7 920 CPU hitting 100C, any tips?

I had a similar problem with one of my older rigs. I cleaned everything, put on a V8 cooler (on an Athlon 64), even turned a desk fan onto it on full blast. Nothing helped. So as HK said, its probably motherboard or CPU. I ended up replacing my CPU and board, but if OP has some spare parts he can pop in, he might be able to isolate the problem.

I would recommend taking a look at the 6 core AMD chips (or Intel if one is rich), if his video editing software takes advantage of the multi core setup, he may end up getting better performance.

Another suggestion would be to install some kind of CPU throttling software, and see if the problem persists if he caps it at some percentage.

But I think if you eliminate all the common problems, the most likely one is that the hardware has just reached the end of its life cycle.

There are still a few things I would try to at least isolate the underlying problem. Seems to me that it's one of three things:

1. The motherboard is overvolting the processor.
2. Not getting good contact between the cpu plate and cooler or maybe bad TIM application.
3. Outright cpu failure.

Still think it would be a good idea to disable Turbo Boost and Hyperthreading, would also manually set vCore instead of running it on auto. Would try a few different vCore settings and monitor to see how closely the changes are reflected.

Probably a good idea to check the cpu plate to make sure the surface is even and not warped, same for the cooler. Might also be a good idea to make sure the bios is current, if so ... it still wouldn't hurt to load default settings and then make the above changes.

I have had a similar experience before. I was running at 70c idle and about 90-100c when gaming etc.

The problem was due to my heatsink and I replaced with an Arctic cooling heatsink (and fan... why not). The idle temp dropped to 40c so double check there are no cracks etc on the heatsink that are preventing the heat from being drawn out.

Sounds like the heatsink is not clipped on properly or there is something like the plastic protector on. The stock heatsinks on Intel chips since the Core 2's have given great stock temps from my experience.

On my i7-920 under load I'm getting 52C. Ambient is probably around 20C atm.
