I7 4790k 95 degrees on 20% load

[elliotairlines]

I am running an I7 4790k and a gtx 1060. As soon as i start to play a game that uses 20% or more load on my CPU then it reaches 90-95 degrees. i was using nzxt cam when getting this info however having used core temp i got the same results. I would assume that this isn't due to hot weather since the problem only started today so is this likely to be faulty hardware?

These temperatures are not justified by hot weather.
First of all make sure that the cpu fans and the others are working.
Have you recently touched something on the computer that may have moved the heatsink?

Hi thanks for the quick reply. firstly i haven't touched anything in my computer since my GPU installation almost 2 years ago. Secondly all fans seem to be running fine. For some additional info I noticed this whilst playing rocket league. Im currently testing out another more CPU intensive game called war thunder and its running at 20-30% load with 70 degrees temps and 1900 rpm fan speed. This still seems too hot but i hope this may help you.Edit: after 5 minutes it increases to around 80 degrees and 2500 rpm speed.

 

[gingerrankin]

air cooling or liquid cooling?


Are you sure that your CPU is only 20% 30%? The GPU that you load has?

 

[elliotairlines]

I am using stock air cooler. Worked fine for me many times in the past despite other people saying otherwise. My cpu load is 20-35 yes and gpu around 60-70% and is running around 50 degrees.

 

[elliotairlines]

Just some extra information to anyone who may be able to help I have reapplied thermal paste and it now reaches about 90 degrees on 40-50% load. Although an improvement still dangerous so i dont know what to try next.

 

[mdd1963]

I think I'd be at least confirming the fan is still working, then cleaning off heat spreader/bottom heat sink, and reapplying a new small amount of super thinly applied thermal compound...

 

[elliotairlines]

As i previously commented based upon rpm the fans seem to be working fine. I have reapplied thermal paste and as noted it made very little difference. I have now tried all options i can think of except clearing cmos and reinstalling windows. It seems very likely a hardware fault so i have a TX3 evo on the way although honestly i think there is more to the issue,

Have you checked your BIOS or possibly the Intel Extreme Tuning Utility to see if your voltages are fine? If your motherboard suddenly developed an issue where it was feeding too much to the CPU, or the CPU suddenly started pulling more power, it could cause these problems.

I'm not sure what else it could be. It seems like your cooling isn't the issue if nothing has changed.

 

[elliotairlines]

Thanks for the reply. After getting the program i noticed it was really in depth and i dont know where to find any info on voltages. Please could you guide me where to look and give me an idea of what numbers i should be seeing?

 

[elliotairlines]

Just to extend on what i previously wrote. I have a stress test cpu-z open. within 10 seconds of going to 96% usage the cpu reached 94 degrees and was measured to be about 1.2V. Hope this helps.

to view voltage in the bottom right hand sub-window or box, clik on the icon of a wrench to make sure all values are showing - then "core voltage" (circled should be showing current voltage - if you run a game, it will display voltage being supplied as it varies, depending on the load demand

for the time being, open XTU, make sure the lower right box is displaying all the values, minimize XTU and move to the side, run your game and note what voltage jumps to

 

[elliotairlines]

When on a game the voltage went from between 1.00 and 1.207. my cpu reached 84 degrees during the 10 minutes i was playing with a max load of 25%

 

[The Original Ralph]

your voltage is fine. Honestly, that isn't a bad temp given you're using a stock fan - there's a reason a number of people diss it - it under performs. Hell, it underperformed on my 4790(non-k)

you'd do yourself a favor upgrading to an aftermarket fan, On my 4790, with a noctua nh-U12S, with my cpu on 99-100% load, i see 66-68C temps, max. Ambient temp in the house is 77F (25C)

fwiw

 

[justin.m.beauvais]

That 1.207V is a little on the high side of normal. Just to confirm, you don't have any sort of overclock on it? And you are running the stock cooler?

Running the stock cooler you should have always been around 80-90 C under load at max turbo. It is the high clock speeds causing a higher power draw more than the actual load on the CPU that generates your heat. Even though you are only at 25% load, that 25% is taking the whole CPU into account, which means the CPU is cranking up to max turbo on 1 core/2 threads instead of spreading the work out across all 4 cores/8 threads. That is interesting and I have no idea what could be causing that. Have you done any updates lately? Installed anything new? Had any reason to tweak power settings or core affinity?

This could very well be a software issue if my theory is on the right track... or it is possible that the warm weather simply added to the problem that was already there.

 

[elliotairlines]

Firstly yes i have stock CPU cooler and no overclock. I have a friend who suggested that although very unlikely the windows update the night before could have triggered something that may have caused this issue. As for the weather its easily for the past few days of using the pc been around 10 degrees more than the average. My room doesn't help this because it keeps in heat really well. What i shall do is reinstall my windows and if that fails buy a new cooler to at least minimise the problem until i figure what is going on.

 

[elliotairlines]

Ralph thanks for your reply.I have had stock cpu temps on this for almost 3 years typically on 50+% load i would expect temps in the 80s. So my question would be why so suddenly? Although I agree they are not great from people who i have asked if the cooler is an issue then something else is also contributing so it would be useful to figure that aswell

 

[The Original Ralph]

could have been a lot of unknown issues, maybe it was the latest updates

if you're going to re-install windows, make sure to go into update history and note the last few updates so you don't re-install them after installing windows. If temps are as they were before, and then jump up after the last few updates are again installed, then you've identified the issue

 

[elliotairlines]

Reinstalling to base windows without doing any updates has made no difference. I'm really stuck on what to do next as I have almost tried everything software based.

 

[mdd1963]

Can you double check that all four plastic retaining pins taht hold on the heat sink are still locked down?

 

[elliotairlines]

After checking they are all in place.

 

[The Original Ralph]

check em twice - they're deceptive and can look correct - wiggle the cooler and see if it moves any

 

[elliotairlines]

Just in case this may not be normal since I don't claim to be a pc expert I'm running a bronze certified 500w psu which should run ok however when cpu gets hot it takes 100w or just a little bit more when my tdp is 88w. Not sure if this helps but ill share it anyway

 

[elliotairlines]

Yes ralph double checking confirmed the cooler is solid.

 

[elliotairlines]

Ive got some info that could really help here but I'm not sure. Ive disabled both turbo and hyperthreading in my bios. In doing this the idle temps have risen from 60 degrees to 70-75 and the load from 2% to 30%.
