4790K Stock temperatures (curious if my chip may be bad)

I put together a system with the following specs:

i7 4790k

MSI Z97S Krait Edition ATX board (with latest available bios)

OCZ Trion 100 SSD 240GB

Cryorig H7 Cooler

G. Skill Sniper 1866MHz ram

Antec Neo 500W Power Supply

Gigabyte GTX 960 4GB GPU

I have not done any overclocking at all with this CPU, all motherboard bios options are at factory stock, I did notice with my XMP profile turned on that all cores go to 4.4Ghz, so I

am guessing that's something that the motherboard manufacturer did by default when XMP is turned on, I ran a small Prime95 26.6 FFT 10 minute tests and these are the results I came up with:

I have good case airflow, etc, but it was going into the 80s, an Aida64 FPU test would hit almost 90-99C, and a Realbench test would hit 80-85C.

I've seen several different issued with these chips, so I honestly dont know what should be normal or not, I'm using a better cooler than the stock cooler that came with the chip, everything is seated properly, and I even re-seated the cooler to make sure.

With the XMP profile off I ended up with these results after running the small FFTs in p95 26.6, Realbench was 71-75C, and Aida64 FPU was 83-88C:

Room temp during the testing was about 27C (80F) as I live in Florida, but even testing in the evening when the room temps were between 74-79F the temps were about the same

Gaming seems to range from 65-73C

Intel ETU tests range from 72-75C

The CPU that I have is from an X53 batch made in Vietnam if that makes any difference.

I've done everything I can think of off the top of my head, I've checked my airflow, added the aftermarket CPU cooler, re-seated it twice to make sure it was on good, and run all those tests, made sure my bios was up to date with the latest, etc. Seems like the highest temps come with the P95 26.6 tests, or the Aida64 tests, and the Realbench benchmark test going into the 80s with XMP on, and high 70s (72-75C) with XMP off.

So that leaves me with the question of is that normal for this chip with an aftermarket cooler, or is it possible this chip has bad paste on the IHS and should I consider finding out about an RMA?

Just curious as the last thing I want to end up with is a bad 300$ CPU that isn't working right.

Also wanted to add that I replaced the stock cooler because gaming temps were getting close to 80C and I didn't bother doing full stress tests, because within 20 seconds it was 90C and climbing so temps were high with stock cooler while I was waiting for the H7 to arrive (so I did not use it except for web browsing until I had gotten the H7).

Hello Xyele,

Thank you for joining the Intel communities.

Please check the following thread:

/docs/DOC-23517 https://communities.intel.com/docs/DOC-23517

This thread talks about CPU over heating with this Intel® processor.

I took a look at that thread, and tried using the settings recommended, and that did not seem to bring down my temperatures any, they were still about the same as my first post with Prime95 26.6 or Aida64.

I've re-seated my CPU cooler 3 times now, so I've triple checked that, and made sure I tried all the settings recommended in the ETU to bring down the TDP and lower the voltage, was still about the same.

Running Real-bench gave me 69/69/70/63 on the cores at max. Gaming seems to run in the 60-70C range still. I've turned the Bios feature off that runs all cores at 4.4Ghz, as that would hit 77C running Real-bench. Prime95 is about the same temperatures, so I have stopped using either Aida or Prime altogether now.

Although from what I have seen others were getting those temperatures with the stock cooler after changing the thermal paste, and I'm getting those with an aftermarket cooler, so I dont know if that is just normal at this point, or if the chip doesn't have good paste between the lid and IHS.

I ran the Intel ETU program and hit about 63-67C with the MSI feature off, with it on, was hitting about 73-75C.

This is my first time owning an Intel chip after having AMDs for so long, and after seeing all the problems that I have seen, I wanted to make sure this chip is running properly and isn't running too hot and isn't a bad one. I've pretty much tried everything that I can think of or have read to get the temps down anymore at all after seeing others with air cooling running in the mid 50s to very low 60s or so under load, maybe I just got unlucky with the chip or don't have a powerful enough cooler.

One other thing I'd like to add is that with the stock cooler my bios was showing 50-55C, it's down to 40-43C with the Cryorig H7 cooler I used now, even under the stress tests between the stock cooler and the new cooler it's a temp drop of 10 to almost 20C, so that's why I am thinking something is wrong, and the extra pressure from the new cooler is forcing somewhat better contact with the IHS on the chip.

The Intel® Core i7- 4790K Processor has a thermal specification or Tcase (case temperature) of

 

74.04°C. This is the expected temperature for this chip under normal use. Normal use will be considered anything that a user can run that doesn't stresses out the CPU. When running stress testes or heavy applications you can see the CPU temperature bypassing the Tcase and eventually going up to 80°C/85°C but as soon the processor is released it must go back to whatever normal temperature it is in normal use. The normal temperature of a processor will vary depending on the chassis type and the rest of the hardware used.

100°C is a critical temperature and can generate processor damages. There are a few reasons that can be causing the high temperatures when running the stress test I your system:

In this case please run the https://downloadcenter.intel.com/download/19792/Intel-Processor-Diagnostic-Tool-64-bit- Intel® Processor Diagnostic Tool. The purpose of the Intel® Processor Diagnostic Tool is to verify the functionality of an Intel® microprocessor. The diagnostic checks for brand identification, verifies the processor operating frequency, tests specific processor features and performs a stress test on the processor.

Please make sure you have the latest bios version with your motherboard and let me know the results when you run the Intel® Processor Diagnostic Tool, you can post the result here.

At the top of the Window is a Menu Bar. The "File" Menu allows you to open the TestResults.txt file using Notepad, and allows you to exit IPDT.

Just to make sure it was a good test run, I double checked my bios was up to date, then I cleared my CMOS and set everything to default in the bios, and only turned

on my XMP profile for ram speed, and then ran the test.

These are the results that I got from running the test, and I'm assuming the max temperature is 100/105C? Since I was watching my temps and saw them hit 68-70 during the test.

I can see that this temperature is fine and there are no errors with the processor, I would recommend turning off the XMP (Extreme Memory Profile) mode for a while and check the temperature to see what happens.

Do you get any freezing problems, blue screen of death or any problems when you run your system?

I have not noticed any freezing or BSODs with my system, I've mainly been concerned with making sure that I do not have a chip that has poor paste under the lid, as seems to be so very

common with this chip, as over 300$ for a chip that could possibly have bad paste is very worrisome.

I ran a new diagnostic with the MSI Enhanced Turbo disabled, which I noticed was enabling itself by default with XMP profiles and running all cores a 4.4Ghz instead of the x44 x44 x43 x42 Intel Specs for the chip. These are the results of that test:

Hello Xyele,

I appreciate you have posted this information for us to see it.

This processor is running perfectly fine and you don't need to worry about it, that temperature is OK, please bear in mind that the K processors are hotter than the rest.

Usually when you do a stress test you will see that the temperature will go up but after the stress is done it will go back to a lower temperature.

Best Regards,

Ivan
