Is this normal or worth worrying about i7 4790K temp

[Rushikesh K]

I bought new i7 4790K processor, and i am having 5 fans in my pc, 1 processor fan which came with the processor itself and rest chassis fans. When i play battlefield4 the highest temp reading in msi afterburner is 82 C. As soon as i close the game it drops to 60 C, I am not telling that the temp stays at 82 C , but the highest point is 82C, Intel tells that the high temp ratting limit is 72C, then why my cpu temp is reaching to much high, I also tested this with specs, it also show temp around 79C or so in the middle of the game, but drops to 60-65C as soon as i close the game? I am not at all doing any overclocking and stuff. And i believe my fans are more than sufficient for my setup, the mobo and GPU temps are very low , like 35C around , even at the middle of the game. The only thing alarming me is the CPU temp

don't overclock, disable turbo boost. go to bios and set voltage to manual at minimum voltage required by your procie (1.00v + or something search google for default voltage of your procie)

go get yourself an aftermarket cooler and a good thermal paste.

make sure your case has good airflow and the ambient temp at 22-25 degrees celsius at best.

Don't disable turbo boost or set voltage to manual. Leave any settings at default.

U guyz have been a great help till now, please do one more favour for me by suggesting a good cpy fan

Cooler Master 212 EVO OR Cooler Master Hyper 212X ????

I heard people telling that 212X is better than 212EVO........PLease conferm the same somebody, is it like so?
Any help would be much appriciated

The fact that the temperature rises very quickly suggests to me the issue is the CPU cooler.
If the issue were case cooling, it would take more time.
Cleaning the base and fins of the stock cooler, cleaning the CPU, reapplying thermal paste and reseating the cooler might be enough.
The stock coolers aren't great at the best of times though.
I recommend buying one of these Cooler Master coolers, removing the stock cooler, cleaning the CPU and correctly installing the cooler master CPU cooler with the supplied thermal paste.
212X looks to be a newer version. I can't see any detailed reviews for it, but it looks similar. You can use either.

I have been running a i7 2600k for the last 2 years mostly O/C'd at 4.2 gHz and have not ran into any temperature issues and or even a single crash with the same setup as I have described above. My cpu idles at ~38C and tops out somewhere near 55C even under stress testing. Also I use RealTemp to capture the temperature.

Picking a CPU cooler really doesn't take much effort. It's a little bit of physics. The more surface area the heat sink has and the better the airflow will allow for great temperatures. Just make sure it will fit in your case and motherboard so that it doesn't snag the memory or other components. Something like this will do great. It's $30 shipped after rebate and it does a really good job: http://www.newegg.com/Product/Product.aspx?Item=N82E16835103099&cm_re=heatsink-_-35-103-099-_-Product



However do not put off the most important part in a CPU cooler. Like many have suggested in this post, the method of installation is key. You almost have to be OCD about the process or you will get it wrong and end up hurting the CPU more than helping it.
The stock cooler does NOT help you understand this process because it seems so simple, however if you are overclocking you want to do some research on this topic. I literally spend 2 hours watching YouTube videos to see every expert's opinion. The fact is you have to get the contact points 100% clean and the CPU paste needs to be applied in the correct amount. a little too much or too little and you will end up hurting the temperature then helping it. So to help you understand here's my steps on how to install a CPU cooler:

1. Get a high concentrate bottle of rubbing alcohol. Something like this will do: http://www.walgreens.com/store/c/walgreens-isopropyl-alcohol-first-aid-antiseptic/ID=prod6056576-product?ext=gooMedicines_ampersand_Treatments_PLA_Antibiotics_ampersand_Antiseptics_prod6056576_pla&adtype=pla&kpid=sku6052670&sst=1262ea15-37b9-6368-4b34-000055f83fc5&kpid=sku6052670

2. Use cotton wipes and q tips and clean the heck out of them. I mean like lab clean.Also make sure there is no residue anywhere on the motherboard or socket

3. Apply the proper amount of cpu paste. I prefer making an X shape with the thermal paste and using the contact pressure from the cooler and the cpu to spread the paste without air bubbles. The total amount of paste should be no more than a dime swipe dot. Like making pancakes try to use the amount of paste that equates to a dime size pancake.

4. make sure the cooler is installed 100% correctly. I find after market cpu coolers easier to install properly than the stock twist on types because you get to screw mount the cooler on the motherboard. Make the contact tight but not too tight that it cracks your motherboard. Most importantly make sure nothing gets dirty and do not touch any of the contacts with your dirty fingers. Use gloves or use plastic wrap to keep your oily fingers off any of the contact points and also keep off the thermal paste.

5. So for thermal paste I prefer the non metallic ones. Even though benchmarks show a slight benefit when using metallic pastes the risk of getting a drop on your motherboard and fry the thing is too great for me to be comfortable with. I would suggest something like this. It has great performance and can't fry your motherboard:

yes after some research i have ordered 212X ,2days before. thanx for ur support, waiting for the new fan, will updat u all once i fit it

Ok m on it, will update u once i finish it, i have ordered 212X cpu fan and can i skip the cleaning alcohol, as i am not finding it in my city(Aurangabad), India, and really thanx , ur post was of much help, i think there is problem with the cpu fan, lets see what r the results after i install the new fan

 

[Rushikesh K]

just a recap here:

1. case fans are sucking into the case from the front and then exhausting out the top and back.

2. your CPU is running stock frequencies but have you watched the voltage while it is running that hwifo64 gives that info

3. the fan is clean and running at top rpm, hwinfo will also tell you speed percentage and also rpm.

4. CPU cooler fins have been dusted using compressed air or something.

5. CPU cooler is seated firmly on CPU.

in your bios you should be able to set fans speeds. I would think your CPU is fine. has it always ran this hot. your prime95 temps are way out of range so something is not right with that cooler.

As told by u i downloaded hwifo64, but i cant see fan rpm and temps?
And this is the new build by myself, the only issue i am facing is the temp, from the first day, i play battlefield 4, and i have noticed that the temp of the CPU goes to 91'C in just 9 min......from then i stopped doing all the work and m working on this issue.

this is where you should download that program from:

http://www.hwinfo.com/download.php

this is what mine looks like at startup:

http://prntscr.com/4swq7a

i click run then I see this:

http://prntscr.com/4swqzv

if you were to click on any of the sensors on the left column you will get a pop out window that will show you a line graph over time. you can open multiple windows that way. Like this:

http://prntscr.com/4swrxv

this is 12 passes through prime 95. there are better programs for your CPU i believe.

No. do not skip any steps. if you cannot find the alcohol try to see if you can get this: http://www.newegg.com/Product/Product.aspx?Item=N82E16835100010&nm_mc=KNC-GoogleAdwords-PC&cm_mmc=KNC-GoogleAdwords-PC-_-pla-_-Thermal+Compound+%2f+Grease-_-N82E16835100010&gclid=Cj0KEQjwtb6hBRC_57Pvyfn66LsBEiQAtlFVu4Gt6dyN8T29Dc9ZqjzD1EB_Tbg5uO9OtBjYgdJG3bcaAvAP8P8HAQ

usually drug stores can carry the isopropyl alcohol that is over 90% pure to clean the CPU. you can also use a coffee filter to wipe it down as it is lint free.

[Rushikesh K]

Sir , so i should ask them directly that i need a isopropyl with 90% alcohol, for cleaning Cpu ?

it is usually on a shelf at the drugstore here in the states but I always ask if I cannot find something.

then just use a coffee filter to wipe everything down.

Sir, please check these links and tell me which to buy, m confused with these isopropyl solutions

they both look good to me. I would use the higher rated seller. You can not tell how pure the solution is but it does not make that big of a difference, you just want the least amount of residue left on the CPU and cooler as possible.

Thanx a lot for ur quick reply, and i have mailed them both stating my use and requirnment, i will buy any one of the two options , as per their reply and our requirnment.


i bought cooler master hyper 212x, the temp redused only by 5%.......now m totaly frustrated and prime95 test for just less than 1minute is giving temps as high as 100C......plz suggest me what to do, i have also sent my cpu to itel support, and they told me that it is having no problem, got my processor back 8days before, but still my problem persists...

what are your idle temps and also what frequency is your CPU running at.

when running prime95 or any other CPU benchmark what is yor CPU frequency and also what voltage are you running at

cpu-z should give you voltage numbers.

Sir take a look at this pic http://prntscr.com/59x5m6
it is taken while running prime95 test for only 4seconds, and the Cpu temps goes straight from 55Cto100C(Note-My Cpu case lid is also open, still getting same high temps)

These are the results with Aida64 stress test (stress FPU)..... http://prntscr.com/59x7at

Both the results are almost same in just 1-3 seconds they reach 100C
My idle temp at start up is around 45-55C......after startup its around 51-55C
Any help will be much appriciated

If it is really running at 4.1GHz at a core voltage of 1.1 I can really only surmise that it is not mounted correctly. try laying your case so that the cooler is perpendicular to the floor and run a test and see if there is any improvement.

did you only use a small drop of thermal paste while installing

 

[RobCrezz]

As the paste off the stock cooler is quite new, you should be able to wipe it off without alcohol no problem.

Sir i have mounted the fan perpendicular only, and i have only used 1 drop of thermal paste, but is there any prob with 4.1Ghz running at 1.1V

 

[fkr]

so the motherboard is laying flat on the ground. I just want to use gravity to hold the cooler down. I think the cooler may not be tightened down enough

your voltages are fine if not below stock

[fkr]

i still think something is not right while testing, maybe do not use prime 95 anymore and try this one they recommend

http://www.overclock3d.net/articles/cpu_mainboard/how_to_manually_set_and_undervolt_your_cpu_vcore/1

the above will also help to lower temps with undervolting altho you should not need to.
