I7 4790k high temp

[Sneakyone]

I recently built a rig with an i7 4790K cooled by a cooler master hyper 212 evo. It idles at around 30-33c but whenci ran intel burn test i peaked out at around 100c. I know that these chips seem to do that a lot. While gaming the hottest temp i got was 71c and it was after going into a heavily populated area in an MMO. Are these temps normal?

I am going to try what vmax recommended when i get home before i pull off the heatsink, sorry for making this a 2 day ordeal.

Do let me know how it goes. Definitely play around with the bios settings and do a few runs with different settings and check temps with intelburn to see where you are. Your Hyper 212 evo is more than good enough to keep temps low and in check. First set everything to stock in bios i.e everything in auto mode as a base line.

and as others have said, do reseat the Hyper 212 if temps are not idling mid to high 20's and in IntelBurn standard test at 50 to 60 degrees during 100% CPU load. I use MX-4 which is great but whatever you have at hand should do. A small pea size, rice grain.

The above is based on ambient at around 20 to 22 degrees

Also if you have your H100i to hand... use it for comparison.... it is a great cooler. I use it and have been using one for over a year. You should not have to worry about it at all.

I am using arctic 5 for my tim, this is was my first time applying it so its very possible i botched it. Like i said ill play around with the bios and post pics when i re-seat the heatsink

 

[vMax]

Arctic 5 is more than good enough.... just a very small amount is required.

 

[Sneakyone]

I unfortunately dont have the h100i anymore but if i am unable to get the temp down i might purchase it again or get a noctua nh D14 like Easylover recommended as liquid cooling with corsair coolers kind of intimidates me

 

[vMax]

The Noctua is an awesome cooler, probably the best but it is huge so make sure you have enough room in your case... can't go wrong with the Noctua. I think the Noctua NH-D15 version might be out now as well. it is...http://www.tomshardware.com/news/noctua-nh-d15-cpu-cooler,26498.html

With a HAF X, I'd go for the Noctua, you definitely have space.

Hi Sneakyone, have been through this with the core i7-4790kOk and we have managed to drop temps. Something to do with Bios settings... You will see some threads here about this already. So after looking at things in a bit more detail for me to get the temps of the i7-4790k to run at mid 20's idle and mid 60's 100% load in prime95 at 4.4ghz, 4.5 or (4.7GHZ temps reach 80 degrees) without touching voltage fully stable, (screen cap below) I have to run the following settings in bios on Maximus Hero vii (should work on other boards with similar setup).

Everything in auto except the following:

AI - Manual
BLK - 100.0 sure you could push this ever so slightly
Multi-core Enhancement - Disabled
CPU Core Ratio - Sync All Cores
44 i have set to 44 but have tested at 45 no problems (4.5ghz)
EPU Saving mode disabled
CPU level up - 4.00g
Extreme Tweaking disabled
Memory at stated speed... i.e mine is at 1866 set yours to whatever it is.

The above should make your cpu run full at 4.4ghz with no heat penalty and 4.5 as well... again being a noob i have no idea why. If i touch xmp it seems to set the temps high or could be mce or even epu mode not sure at all but the above will definitely keep things running cool and you can overclock at cool temps but will have to play with vcore to go above 4.6...

Again please be aware i am new at this but the above works for me and keeps temps very low mid 20's idle and no more than 63 degrees in prime95.

Screenprint 4.4ghz



Even at small fft or whatever the hardcore moment is with Prime95 it does not go over 64/65 degrees. I have a H100i watercooler but temps should be a bit lower for you.

Your temps are about right now... so everything should be ok.

I have set everything like you stated, except im confused as to the CPU level up part, I cannot set it to 4.00, I will be running stress tests in a second and will post results.

After a 10 minute test using Aida64 the highest temps reached were 87, 89, 87, and 82 measuring with RealTemp, average temp was around 64-77c across all 4 cores.

Using the Intel Extreme tuning utility for 5 minutes the temps were 78, 80, 77, 70 and it hung around 75 most of the time

Using Intel Burn test for about 2 minutes I got a max 100c for temp and it averaged everywhere from 75c to 95c

Using Prime95 blend test temps went up to 100c but not right away, it stayed around high 60s mid 70s then hit the 90s about 8 minutes into the test. I have heard that Prime 95 does not like to play with Haswell Processors so Im not sure about how it tests.

Are these temps normal for my configuration? Should I still re-seat the Heatsink?

 

[EasyLover]

Reaching 100c is still not a good sign. Remaining values are ok for this setup. There is nothing wrong if you redo HSF.

 

[vMax]

Agree with Easylover... temps still too high especially in Intelburn (was that the standard test). Do try reseating first.

I removed the heatsink, here are some pics of the Thermal paste contact surface, there was some on the sides of the CPU so I am assuming I put too much the first time.

Here is a pic of the bead of thermal paste I just put on

Spoiler

Upon booting the idle temps have not changed much, and running the intel burn test I still get temps that fluctuate between 70 and 100c

 

[ewok93]

That's a little too much, I think that's your problem.

 

[Sneakyone]

That's a little too much, I think that's your problem.

I do not have time to re-seat it before work, I will re-seat it again when I get home and post pics here. Can you post a picture of what it should look like? There are many methods ive seen people use when applying this stuff and im not sure which one is correct.

 

[ewok93]

This. http://www.tomshardware.com/reviews/thermal-paste-heat-sink-heat-spreader,3600-5.html This guide explains it well. You don't need to spread it manually and it doesn't need to cover the whole thing.

 

[EasyLover]

That is too much thermal paste you've applied.

 

[Sneakyone]

Im back and ive re-seated the heatsink, Here is the amount ive put this time

[Sneakyone]

After doing the same tests the temps appear to have gotten a bit worse, when I ran a CPU stress test in Aida 64 yesterday I did not get an overheat warning, today I did. really not sure where to go from here with this.

 

[ewok93]

That looks like too little haha. It's hard to tell with that perspective, but it doesn't seem like that's going to spread much. You don't want it overflowing, just enough to cover the hot spot. It takes practice to get it perfect.

 

[vMax]

Sorry away for a while. Yep you did have to much thermal paste but on your second run it seems to be about right. Still have no idea why you are hitting almost 100 degrees in Aida64... Aida64 is never that hard on the CPU. I still think it is a setting in the bios as I seem to have the same setup other than the cooler which I think on your side should not make a huge difference.. Sorry mate, now how you feel as I went through it as well. Have you set your vcore to adaptive and tried that... also are you running memory in XMP profile? as that might have a bearing. Try to run it without XMP and just set the memory to whatever yours is i.e 1600 etc.

I dont think im running it in XMP, my current bios settings are like this in the extreme tweaker tab
Multicore enhancement - Auto
CPU Core ratio - Sync all cores
DRAM frequency - 1333Mhz
Extreme Tweaking - Disabled
CPU Level Up - Auto
EPU power saving mode - disabled
Everything else is auto
CPU core voltage - 1.072 Adaptive mode
Offset mode sign - +
CPU core voltage offset - Auto
additional turbo mode CPU core voltage - Auto
CPU cache voltage - 1.204 Auto
DRAM Voltage - 1.513 Auto

Voltage for my vcore says 1.072 right now from mobo, I am idling at 35 degrees @ 4.0 GHz

Ran tests using Aida64 CPU stress test, FPU stress test, and Cache stress test shot my temps up to the 90s in the first minute of testing, average temps during the test were in the 80s. 4 minutes in Aida reported thermal throttling.
CPU Core voltage at 100% load was 1.279 according to CPU-Z, the same as yesterday

Tests using the Intel Extreme tuning utility made temps rise to no more than 86 degrees according to Realtemp, Core voltage under 100% load in that test according to CPU-Z was 1.260v


I could try to re-seat the fan again but at this point im not sure if it will even help, I am using bios version 1002 is that helps at all, My 212 Evo is running the stock fan and a Cougar fan in push/pull config at max speeds with a rear 140mm exhaust and 2 200mm top exhaust fans, im beginning to think this chip just runs really hot as tons of people have had these problems when running tests, it still concerns me though. It is an L4 batch chip by the way.

UPDATE; I updated Bios to 1004 and turned Turbo off in the options, Now at 4GHz I dont get temps exceeding 83c on 100% load with Prime, Aida, or Intel Burn Test, not sure if this is okay though.

 

[ewok93]

That's still a little high. It really isn't enough paste, it's tricky but you have to get it just right. If you take the heatsink off, I'm willing to bet it won't have spread to cover the whole hot spot.

 

[Sneakyone]

I will re-seat the heatsink again when i get home and post another pic, though the last time i reseated i noticed a mark on the cpu, its visible in the last pic i took down near the bottom right corner of the CPU, it wouldnt clean off when i removed the paste, should i be worried about it?
