Intl I7 4770k displaying weird temps when running Prime95

post #1 of 10
Thread Starter 
I've owned a I7 4770k ever since December, and I just recently decided to get around to overclocking it. I've done some overclocking before so I know the basics and all I'm trying to achieve is a nice 4.4 ghz right now. Well I currently have it set to 4.4 ghz, have the voltage adjusted and everything. and at ideal my temps are around 30c but this is what is confusing me. As soon as I run Prime95, my cpu peaks out at 100% which is normal, but my temps instantly go to 90c and I mean instant. not a quick clime or anything. I just see it go from 30 to 90 with nothing in between. And I know that can't be right at all.

What cooler are you using and what voltage do you have the CPU running at?

Cooler Master Hyper Evo 212 with a push pull config and voltage is at 1.346v but still i don't get why it will instantly go to those temps during a stress test. there is 0 i mean 0 temp climb. its 30c ideal 1 second then a millasecond latter 90c

It makes sense that this is happening. Haswell chips run very hot and that cooler won't be able to keep up.

The worse the cooler is, the faster the temperature will hit it's maximum.

Dude. How can the chip instantly go to those temps. Ive never seen that happen with anything ive overclocked. It will climb up temps. But not go from 30 to 90 in a split second with no in between temsp.....

Haswell is a different beast. The chips just run ridiculously hot due to the TIM they use between the die and the IHS.

Well I guess I will be waiting to overclock it when I get a new case and a h105

You could always give delidding a try. At your own risk of course, it will void your warranty!

I will probably do that to my Haswell-E chip that I plan on buying since that's when I plan on making my own custom loop. I was just trying to get a little more power out of this chip while the HT is turned on.

When doing some full load temperature testing check out ThrottleStop. It has a few advantages compared to other monitoring programs. It monitors the CPU temperature sensors at a higher Windows priority level compared to other monitoring programs. This means it is first in line when getting temperature data from the CPU so it usually reports the highest and most accurate temperatures. It also has a More Data option so you can use that to sample the temperature sensors more frequently which also helps it record the highest temperatures. Combine that with the Log File option and you should be able to track the rapid increase in your Haswell temperatures a little more accurately.

An overclocked and over volted Haswell puts out some big time heat. Might as well use some monitoring software that can tell you how hot your CPU really is. I have seen some monitoring programs under report the peak core temperature by as much as 10C when the CPU is fully loaded with Prime95 or LinX.

ThrottleStop 7.00 includes offset voltage adjustment for the Haswell CPUs. Send me a PM if you need a copy of that.
