but are temps like that normal? of do you think something might be wrong?

Which version of Prime 95? IIRC version 28.5 does that to Haswell, a lot of people don't recommend to use prime with Haswell chips because of that. It's to do with a new instruction set in the chip

Now I think of it are you using adaptive/offset voltage to overclock? I believe what happens is the CPU adds .1v to the set Vcore in some stress test situations like Prime or IBT, I think if you use a fixed voltage and keep the speed step and the c-states enabled you can avoid the voltage 'boost' and still have it downclock at idle.

But hey I just recall this from reading threads around, hopefully I'm pointing you in the right direction.

Try that guide it will explain more then I can.

If I'm way off, apologies for the long lot of nowt tongue.gif Try remounting smile.gif

Edit I also have a feeling that 1.3 v on Haswell is pushing the limits on air to..

thanks!
thats a very useful link

They seem high but depends on how you were testing and what temps are.

Been using the x264 now. Temps are very good, but the cpu only seems to be able to get to 4.6 frown.gif

Going by the statistics on that guide I posted you have an average chip, not bad. My 3570k needs 1.32 volts to be stable at 4.4 ghz I can't get 4.5 to boot with less then 1.376 volts fixed in BIOS, and thats out of my personal voltage/temperature comfort zone. smile.gif

Huh. Guess I shouldn't be dissapointed by my results then.
Wish you better luck on your next CPU then,whatever that might be smile.gif

Cheers bud, you might well be able to tweak it a bit further yet, best of luck thumb.gif

I've tested with CP9, PH-NDC, NT-H1, MX-4, CF3, and DC1 and find them all to perform very well.
Except for a few very hard to you TIMs like Coollaboratory Liquid Pro, the difference between top 20 is about 2c. Once we allow for variables involved in testing that difference is more like 1c. Things like barometric pressure, humidity, slight changes in temperature, how good the TIM print is, etc. can easily skew results by 2-3c.

Thanks Doyll!

I'll stay with the CP9 save myself $10 USD then. hahaha

is there any chance i mounted the cooler wrong if im getting temps this high?

That's a lot of voltage for that clock speed on a 4690K. Are you sure the chip needs that much to get there? I have set up a number of 4690/4790K, and none of them needed more than 1.22V to hit 4.5GHz. Also, as a previous poster pointed out, using adaptive voltage can really skew things badly.
