my 4790k is overheating and reaching 95°c

ajbuilds · Jul 11, 2015

i just built this new pc and went with a 4790k cpu , i'm using the stock cooler until the water cooler arrives ( btw it's a deepcool capitain 240) , idle temp is 43° but when i start battlefield 4 on ultra settings , temps go crazy , like 90°c is the average temperature , what should i do exactly ?

my configuration is :
mobo :msi gaming 5 z97
gpu : msi gtx 980
case : corsair 760t
psu : lepa b800m
hdd : 1tb seagate

Are all the clips in all the way, the same thing happened to me one time with the same CPU.
Also, you didn't put any compound on correct? Because it comes preapplied

Make sure the cooling fan for the CPU is actually working, turning, running. Double check your CPU cooler mounting to verify it's firmly seated all the way around. Make sure all case fans are connected and operating. Double check the bios settings and it would probably be a good idea to make sure to reset the bios to optimal default settings. There is definitely a thermal issue and I would not game with that unit until you resolve the problem. Your temps are way too high for a stock configuration. Are you overclocking the CPU by any chance?

all the clips are in all the way , no i didn't put any compound :/

ajbuilds · Jul 11, 2015

no i'm not overclocking , how can i reset the bios to optimal default settings ?

The stock cooler should provide enough cooling as the processor only uses 88 watts and I believe Intel's stock cooler is rated to 95 watts of cooling I would make sure the fan is spinning properly and its header is fully plugged in. if it is it's possible the problem is with the processor itself, this is a common problem with this chip. It would be a good Idea to contact intel support and get more information from a professional and possibly get a replacement chip.

ajbuilds :

you go into the bios and load optimized defaults

hopefully you took off the plastic film that covers new cpu coolers before putting it on

you are going to need to re-seat the cpu cooler

wipe all old paste with isopropyl alcohol and either cotton swabs or coffee filters

follow this guide:

Stock Intel coolers for high end CPUs are garbage.

Darkbreeze · Jul 11, 2015

Did you remove the plastic protective sheet that covers the thermal pad on the bottom of the stock cooler before you installed the cooler?

ajbuilds · Jul 11, 2015

of course i did , i've just updated the mobo bios , during the installation the temperature reached more than 100° , now it's on 38° , what are the exact voltage numbers that the mobo should be set on ?

Darkbreeze · Jul 11, 2015

The CPU and RAM voltages should probably be set to Auto unless you're manually overclocking. And I wouldn't agree with "Of course I did", as a general rule. You'd be surprised how many people I've seen who DIDN'T remove the protective sheet. Even a few that had built rigs before and just spaced it out.

So, what is the ambient temperature of the room where the unit is located? After having updated the BIOS, I'd go back in there and reset it again to optimal defaults if you're not overclocking. I'd also set the fan cooling profiles for the CPU fan and case fans to the "standard" setting in the BIOS if they're set to anything other than that.

How many case fans to you have installed and in what orientation? You didn't happen to remove the CPU fan from the heatsink before installing it did you. Probably not, but I gotta ask. I've seen people remove them for whatever reason and then put them back on facing the wrong way.

1. Have you overclocked your CPU? If so bring it back to stock.

2. Remove the CPU & the cooler, clean off the thermal paste with 70% or higher alcohol and properly reapply thermal paste and the CPU into the socket!

3. If these do not work my question is ... Do you have a small case with bad airflow? or Perhaps your ambient temp is quite high...

ajbuilds · Jul 12, 2015

after the bios update temps are significantly lower , 37° idle and a maximum of 84° during gaming ( stock cooler fan set to 100% ) , the case came with 2 front 140 intake fans and one 140 exhaust fan , the ambient temperature is about 25° , how can i reset bios again to optimal defaults ?

Darkbreeze · Jul 12, 2015

Power on the unit and begin pressing Delete to access the BIOS. Once in the BIOS press F6, save settings and reboot. During reboot press delete again to go back into the bios after resetting the default values and configure your fan profiles again as they will likely change if they were altered previously.

I'd set the fan controls to "Smart fan mode" so they are adjusted according to temperature. Having the case and CPU fans at full speed at all times will likely be annoying, but that's fine too until your thermal issue is resolved. Your newer temps since updating the bios are still pretty high for normal operation, even while gaming. There must still be some kind of issue. You should not have temps over 70°C unless you're running some kind of stress test that locks all cores at 100% usage or the process/game your running is taking it to 100% core usage on all cores.

well i did all the things you mentioned darkbreeze but nothing changed , in fact now i discovered more problems , in some games i can't turn vsync off , if i do , for 5 seconds the gpu makes a strage low noise then a sudden restart occurs , heat has nothing to do with it this time

Darkbreeze · Jul 13, 2015

Setting the bios to defaults should never cause an issue unless there is already an issue, or an incompatibility. I'd double check your settings in the bios manually. Make sure the RAM is configured for the correct speed, latency and voltage, according to the specifications for your modules, which you don't list above.

Try fiddling with the compatibility support module settings, if any are present. Sometimes enabling or disabling CSM can cause unexpected results with UEFI bios hardware devices and it may be that resetting to defaults has changed that setting although it really shouldn't be an issue unless you had manually changed that setting previously.

The fact is that optimal bios defaults and fan profiles should have little to nothing to do with any of the issues you're describing, and would seem to be more in line with a faulty motherboard or graphics card, but after several rounds of overheating the chipset or cpu, just about anything is suspect.

oh i forgot to mention that i'm using 2x4gb corsair vengeance lp , i was wrong about the creepy sound , it's coming out of the psu not the gpu , same issue with farcry 3 , if vsync is off pc restarts after 5 seconds

Darkbreeze · Jul 15, 2015

I'd replace the PSU. Lepa makes mostly crap anyhow, plus if it's making weird noises and you're having abnormal behaviors, the PSU would have been the first place I'd recommend convicting anyhow.

ajbuilds · Jul 15, 2015

and that's what will happen this week , i'll make sure to post every detail about this problem ,thanks for helping me out man

Darkbreeze · Jul 15, 2015

No problem. I wish we'd have known that was where the sound was coming from to start with, maybe we could have got this fixed for you already. Let me know how it goes. I'd use the following two links to help you with selecting a new power supply. Recommended capacities based on your card model, and recommended units based on quality and reliability, are shown at these two links. Stick to tier 1 or tier 2 units only on the PSU tier list if at all possible. Tier 3 units shouldn't be used with gaming cards or overclocked rigs, and tier 4 and 5 units shouldn't be used at all. What is the exact model of your LEPA power supply. It might not be one of their crappy models.

Darkbreeze · Jul 15, 2015

Nevermind, I see it's the B series modular. That's likely a tier 4 unit, as the B1000M is a tier 4 unit, which is junk.

Two of my friends offered to give me a brand new psu for free, should i choose the Cooler master G650M or an antec neo echo 620 ?

Darkbreeze · Jul 25, 2015

Neo Eco 620. That's a Seasonic built platform.

ajbuilds · Jul 29, 2015

bad news he sold that one , i took the cooler master , it's not that bad after all and i paid nothing for it , no more noise yet the cpu is still heating , i m going to RMA it soon

Darkbreeze · Jul 29, 2015

Cooler Master power supplies are terrible. Nearly all of them are incapable of providing their labeled capacity and are poorly built. There are a couple of exceptions, but that model is not one of them. I'd get my money back.

CM is well known for using liar labels and farming work out to disreputable OEM builders for their products. Those of us with some familiarity with the internal platforms try to avoid their power supplies, and lately, most of their products, as they've gone from bad to worse in most cases.
