I7 4790k high temps?

Hi guys, I've just upgraded to the following:

Gigabyte z97 s-oc force
4790k
8gb corsair vengeance 1866mhz

I'm using an xspc raystorm cpu block and 2 x ek pe240 rads with corsair sp120 fans.

I've got a couple of questions should probably be in the oc section but:

In the bios I set the cpu voltage to 1.3v. In hwmonitor I've got 2 readings, vcore in the mobo section =1.32v and cpu vid in the cpu section = 1.302v which is the same as CPUz is showing. Which one should I be monitoring?

Also at that voltage at 4.7ghz in a 19 deg c ambient room it's hitting 90 deg c socket and from 81-88 deg c on cores running Intel burnt test on very high (4gb) setting. Is that normal? I'm used to amd at 45 deg c haha.

I've got the basic gist of what I'm doing but if anyone could point me in the direction of a decent oc guide would be much appreciated. Many thanks in advance.
 
That is far too hot - shouldn't be that high but running a burn in test just loads the CPU unnecessarily.

Download and install RealTemp and monitor it while using the PC normally. You may also wish to re-seat the cpu cooler and check the contact it has to the CPU and replace the thermal paste/pad.
 
To add I've just enabled xmp for the memory and voltages now read 1.273v CPUz and 1.296v hwmonitor.

4.7ghz xmp enabled it scored 946 on cinebench r15 which looks about right comparing to the leaderboard on here.
 
Ok I downloaded real temp and the temps correlate with the hwmonitor ones. The cpu block didn't come with instructions so I had to trawl YouTube to find out how to fit it. I used ic diamond blob method. The block mounts in a wierd way the posts have a thumb nut on them which you do up to the top. Then you first screw all 4 down to the stop with the springs etc on then adjust the thumb nuts to tighten it the rest. Should those be tightened to the stops or just nipped as over tightening would cause high temps as well wouldn't it?
 
Ok I downloaded asus realbench to get a different perspective and running it in stress test mode at 8gb ram the max is 69 deg c so maybe it was just ibt hammers it far more?
 
The problem is most likely the heat-shield isn't making proper contact with the die. This is a common problem across all Haswell chips.

If you really want to bring temps down your best bet is to de-lid and go direct die contact with your waterblock (you may need an adjustment socket for your waterblock to make up for the difference in height). Alternatively don't run Intel Burn Test, what it does isn't a realistic representation of day to day a consumer CPU will typically be doing (rendering, gaming, coding, folding etc).
 
I havnt got the confidence to delid that's way out my comfort zone haha. I did notice power output differences between ibt and realbench. Ibt hwmonitor was reading 171w and realbench 119w. Realbench is definitely the more real world test so I'll use that for stability.

It's real test will come shortly when I run fsx as that's one of the main reasons I switched from amd to Intel so I can finally max it out. I've had it since 2006 and my fx8350 was close to achieving it but not quite.
 
Its normal on haswell, its to do with how they're pasted instead of soldered. Hence why you see people delidding them. Any stress test that uses AVX instructions will cause temps to skyrocket. Hence Intel themselves don't reccomend the likes of p95, IBT etc.
 
Ah I see okie dokie. I've been running fsx for about 3 hours now and max temp so far is 61 deg c. And I've finally done it. Fsx maxed out everything possible 110m cloud draw the lot and using the aerosoft Airbus x and gatwick extreme scenery was doing 31fps on the ground online on vatsim with other aircraft close by. Well happy :D
 
61c is pretty good, on air cooling mine on a similair voltage and clockspeed will run anything from 60-74c on the hottest core depending on ambient temp.
