4670k hit 100c with Prime95

I just built my computer last week, and ran prime95 today to see if I had any room for a slight overclock but my temps shot up to 98-100c on all cores..

Once I noticed this I immediately closed prime95 but I didn't notice my CPU was still at full load until 5 minutes later when I pulled up realtemp. after that I just shutdown the whole computer.

Is there any way I damaged my CPU while it sat at 100c for 5 minutes?

I don't think so. unless you had some crazy voltage it's probably okay. What kind of cooling solution are you using?
No, your computer will shut itself down to avoid damage.

Sounds like your cpu heatsink is not seated properly, Take it off, remove all thermal paste, repaste and put it back on nice and tight

Ive yet to see anyone be able to get theirs above 100c

The CPU throttles its self so well that I believe that is the max you will see with a cooler attached and sane voltages.

Deffo no damage will be caused by a few mins of that.

Thanks everyone that's good to hear!

It's all stock (cooler and bios settings on the UD4H) so I think I just shouldn't be stress testing it.

It idles around 35-39c and hits max 69c when I'm gaming so I figured the cooler was seated correctly but maybe not. I'll give it a check tonight.

Thanks again everyone for the help!

Those seem like normal temps, my brothers was almost exactly the same way with stock cooling, when idle/playing a game when his room was about 30-35 Celsius.
Yeah, the stock cooler just isn't going to cut it for extensive stress testing with something like Prime95, especially in Auto volts (which can be significantly higher than needed). Spend $25 on a Hyper 212+ EVO if you intend to do anything demanding with the chip, or if you want to dabble in overclocking it.
Having a stock processor throttle on any workload even with the stock cooler is just pathetic and I would consider it a defective product. Intel please....

Welcome to Haswell.

You could say that about IBT or something but prime95 is an actual program and not just a stress test. Stock processor cooling solutions have always been enough to prevent throttling in any work load as long as the ambient temps weren't unrealistically high.

Intel needs fix Haswell's ridiculous TIM and glue problem or include a better heatsink. This is just unacceptable. Intel is a very smart and successful company, they know this problem is there but they know customers have to deal with it because the only alternative is a slow and very inefficient Vishera.

A CPU should ship with a cooler capable of controlling temperatures at stock frequencies at full out maximum loading or not include any cooler at all.

Ivy could operate at stock frequencies at maximum loading and so could all the AMD chips. This is with stock cooling.

At least they are doing right with the 2011 Chips.
