Are those temps ok for a i7-4770k?

[Som3one]

Hi there,

yeah, it´s another one of those "are my temps ok?" threads.
Sorry about that.


Anyway, I already discussed my problem in another topic, I opened. But my original question back then was somewhat different and I have been adviced to open another one with a more suitable title.



Now, here my problelm. About two weeks ago I decided it´s time for a new rig and this is what came out:
CPU: i7-4770k
Motherboard: Asus Z87 Sabertooth
RAM: 8GB-Kit Corsair Dominator Platinum PC3-17066U CL9-11-10-27
CPU cooler (back then!!): Corsair H100i + 2 x SP120 QE
Graphics card: Gigabyte GTX780 Windforce
Soundcard: Soundblaster Z
PSU: Corsair AX760i


When I finished building it and making sure everything was running as it should (without overclocking anything), I ran Prime 95 and was a bit shocked by the temperatures.
With all the fans running at full speed I would easily hit the 72°C mark.
My old rig was a i5-2500k @ 4,2GHz and was running at only 55/56°C with the same cooler.

I mean, I knew Haswell would get hotter and everything. But 20°C difference is quite something.

I reassembled the H100i to make sure everything was installed fine and looked up some reviews. With the same CPU + cooler configuration, they would usually get around 60°C which got me worried even more.

I looked up some more reviews in which they were using the stock cooler and they would get something around 86°C using Prime or something similar.
I, too, switched to the stock cooler to make sure it wasn´t the H100i. And after 3 minutes I hit 103°C and stopped the test.

I contacted my retailer and they told me to send everything (mobo + CPU + cooler) in to check on it.
Unfortunately, they found nothing. Well, except for a damaged motherboard which kinda happened while packing it. Stupid me.

I told them to keep the CPU and the cooler and they only exchanged the motherboard.
I ordered another i7-4770k from another retailer together with a Kraken x60 and 2 Noctua fans.

After installing everything I would now get around 68°C with Prime running for 15minutes. Which still seems a bit high to me for a Kraken and a non-overclocked 4770k. (On my old rig with a Kraken, I wouldn´t even get over 55°C.)


What do you guys think? Did I maybe miss some hidden setting or something?
And also, how come all those reviewers got such low temps?


Oh yeah, almost forgot: According to Asus AI Suite, all voltages are as they should be.



Sorry for the long text. I wanted you to get the full story.

Haswell CPU's tend to get hot due to the poor IHS contact/heat transfer. Your fine, anything over 85C will be probably lead you to problems. You may of had a bad chip, if your concerned about the temps, (which in real world situations it won't be under load) exchange the CPU or try using a aftermarket thermal paste in order to knock off some degrees.

exchange the CPU

I did.

or try using a aftermarket thermal paste in order to knock off some degrees.

I am...but forgot to mention it.
I am using MX-4.

 

[tomdabomb]

That seems really hot. Is your h100 pumping?
EDIT: sorry i posted that before i finished reading it. i can't seem to delete it either :/

OP what is your Vcore set at with stock clocks? 1.2v? Could try lowering it to 1.1v and retesting

 

[Som3one]

I think it´s to auto.

When running Prime it goes up to a maximum of 1.312V.
According to AI Suite that is.

When running Prime it goes up to a maximum of 1.312V.

Holy crap, it really shouldn't need 1.312V at stock clocks. Unless you just got the absolute worst 4770K on the planet.

Go into the bios and set a fixed Vcore of 1.15v

 

[Som3one]

Now I am feeling stupid.

Looks like I forgot to set the vcore after the exchange of my motherboard.
And I am pretty sure I manually set the vcore to 1.13 on the old one. Which would explain why I didn´t really notice the wrong voltage at 1.31.

Problem with the 4770k and my h100i is definitely the IHS on top of the die. I have temp ofs 33c on my h100i and the CPU is @49-57c while encoding a movie. I am overclocked @4.5GHZ with an adaptive vcore @1.260 VRIN@1.780 to try to reduce heat while the vcore/vid is up but it is the damn heat transfer contact between the cpu and the die does not dissipate correctly without Dlidding. I should of stayed with my 2600k and my ASUS z77. I do notice a performance increase stepping up from the 2600k but was it significant enough to warrant the upgrade to the 4770k. That still need to be determined since I have only had it for 2 weeks.
