Core i5 750 getting insanely hot

My core i5 750 gets insanely hot while under heavy load (97-100% CPU usage). I was doing an H.264 encode, and within minutes the temps in Core Temp peaked at 100 degrees C before I canceled the rip. I'm using the stock cooler with Arctic Silver 5 thermal paste. I plan on ordering a Cooler Master Hyper 212+ at some point. My idle temps seem fine to me:

Core 0: 49
Core 1: 46
Core 2: 50
Core 3: 45

Here's my CPU-Z:



What's the problem, or what should I do or change, to lower these temps while under load before I get my new cooler?

Thanks,

Tony

LOL are you for real you expect to overclock over 1000mhz on a stock heat sink you are crazy the only thing you can do is put it to stock until you get a real cooler anything more then 400 mhz OC will be too much for a stock heat sink to handle. Intel's heat sinks suck to begin with and with an overclock like what you got it has no chance in hell of cooling that processor.

Well thank you for the compliment pal, but I didn't overclock anything.

Woah, Dude, Play nice!

Jeesh.

According to that CPU-Z something did. It could be reading it wrong or the BIOS messed up. The BCLK should be at 133, not 195. Try fixing that, and I bet your temps will go down.

^ Don"t OC on a stock cooler.

did you try re-setting thermal paste?

My stock i5 750 (2.8 GHz) hit 80s when doing the Windows Performance Index test. That was with Arctic Cooling MX-2. The stock HSs are total junk.

Your board probably AutoOCed your CPU, goto the BIOS and turn it off...
(BTW, Thats some good auto OCing BTW..)


Not realy, I tnearly killed his CPU!

I'm amazed the ram stayed stable. 195 BCLK is pretty high. And also, 19x multi? Should be 20x or 21x. Something really weird is going on with that PC.

The mobo is the Asus P7P55D-E. It had indeed "auto-OC" itself. The temps at idle are 24-25 on all cores.

Here is the new CPU-Z, look better now?



So this mobo OC's well apparently?

Much better. Is that a shot when stressed or at idle? All the power saving and Turbo options on?

That's at idle. I haven't stress tested it yet, I'll do it now. What are these power saving settings? I disabled C1E and SpeedStep. Are those the only ones? I read that those should be off. What are the options I should have on?

Those should definitely be on. I can't see why you'd want them off.

Yes, as it hasn't killed the CPU yet, it means you can push 3.7 pretty stable with your new cooler with that setting.
lol


Like an idiot, I have been running it as it was for almost 2 months now. I hadn't really ran it with a high CPU usage until I attempted to encode that movie. Guess it was a good thing.
