Extremely hot CPU Temperatures with 4790K in games

If I should have posted this thread in the overclock/cooling section could a moderator kindly move it over, cheers.

Anyway, I bought this bundle from Overclockers a few years back https://www.overclockers.co.uk/reve...rable-enthusiast-gaming-bundle-bu-007-og.html and I remember being told by a friend at the time that my temps were high but not unreasonably so at the game temperatures stated with MSI Afterburner. I think I remember them being around about 75-80C in games. I have seen graphs online that show 80C maximum = Hot, still playable at this temperature + I saw quite a lot of threads at the time with people reporting similar issues. Benchmarks running at 100C, games running at 90-100C, idle temps like 60-70C. Many of those users experiencing the same issues as me. some of those with stock coolers, some with overclocks, some with liquid/water cooling on a wide range of different motherboard configurations. So instead of worrying myself about it I left it well alone and treated it as the norm with these CPU's running at insane temperatures (70-80 max load) and with my system being pre-overclocked by Overclockers I had faith that everything was safe to go. Fast Forward two years my current idle temp is around about 30-40 but as soon as I load a game, give it 10 minutes to kick in and my CPU slowly creeps up to 90-100C, ouch. As soon as I close the game this slowly drops to around about 30-40 again after a couple of minutes.

Why did I never bother to bring this up in the past 2 years? In all honesty I never leave CPUZ, GPUZ, HW Monitor, MSI Afterburner and all the other software open. I just like to load the PC and play games occasionally :). That was until I had a slight issue with my 1080TI with idle temperatures, since fixed with a custom fan curve with a idle fan temp of 20% <3, thanks whoever mentioned that in the 1080TI thread. Before this I had messed around with my case for airflow, taken off the side and top panel, windows open, door open, desktop fan on. GPU is now idling at 30 and temperatures in game are now decent, around about 65-70C.

This is when I began to notice the extremely high CPU temps with MSI Afterburner on screen display I think it's called, CPU temp in-game rises to 95-100C :(. Not sure if I am getting any throttling or not, fps seems to stay the same, no stutter but the temperatures report a staggering 100C on video games. I always knew my PC rig got a bit warm lol, thought it was normal, but if this has been the case for a while, surely I have caused damage :(? It seems to climb gradually. Tested Rocket League for an hour and it just rose and rose up until the point I had to close the game, minutes later the temps dropped dramatically.

Anyway I pulled my PC apart again today reapplying thermal paste, cleaned the comp of dust, taking the radiator/pump off and resitting or whatever you call it and the same thing happened. Start up temps 27C, load a game (15 minutes later idle) return to the comp and 100C CPU temp. GPU was sat at 67C, Motherboard according to Speccy was 37C, so a huge difference :(. Airflow could be a slight issue here, but not to this extent surely? I made sure my room was well cooled today, fans are all operating as far as I'm aware, side/top panel taken off yet it still jumps to ridiculously high numbers. Something is definitely wrong.

I'm hoping with this being a commonly reported fault in 2014/2015 that somebody knows what the heck is going on and how to fix it on my system. My BIOS Motherboard is on F6. Does this sound like an issue with in case airflow? Fans/pump issue? CPU dying? Overclock? BIOS tweaks needed? Read quite a few threads today dating between 2014-2016 about settings set to auto/enabled that can potentially fry your CPU given time. Trying to get this sorted is definitely a priority, need to get those in game temps down to a safe temperature.

I also tried the laptop high temp fix today on the Windows side of things by turning the maximum processor from 100% to 99%, in doing so this removed my overclock completely and the temperatures dropped to about 65-75%, never did a long game session to see if it increased any further. This still with the case wide open.

Intel Core I7 4790K @ 4.5GHz Devil's Canyon Haswell
Motherboard: Gigabyte Z97X-SOC Force
Cooler: Asetek 570LX 240MM
Case: NZXT H440 Midi-Tower

Rest of my spec should be in the signature. If I need to attach certain screenshots or even record something for 10 minutes no problem, I can do this. You may have to explain things in simple terms with responses though as I may not understand :p. Apologise for the long post. Hoping you lads can help, really don't want to be forking out another £1000 on hardware at the moment.

What voltage is the cpu running at?

You can find this in the bios or through cpu-z

4.4ghz isn't a huge oc on these chips and 1.231v isn't a problem voltage, sounds about right for that chip and the oc.

You can delid
Try and reduce back to stock settings and see what temperatures are

I tried that in the early hours of the morning. Went to the defaults, power management mode set to balanced instead of high power as well (not sure if that makes any difference) and Batman Arkham Knight still crept up to 80-85C :|. If the OC and voltage is fine I suppose I can rule out a a BIOS issue, good news actually. Must be an airflow issue, lack of fans in the case or fan/pump need to be working faster, not sure if they can be made to work quicker is it possible? Also is that liquid cooler adequate? With dual 1440P monitors, 100+ fps in most games the CPU seems to be frying lol, yet the GPU is fine. Decent at idle, decent with none gaming apps, decent with browsing, games however struggling. Usage isn't even high in most of them yet the temperature is rising and rising on the CPU. I will probably leave that delid as a last resort as I have absolutely no idea what that is, nor know anybody who could do this without damaging it.

What would be the best way to get a decent enough airflow in the NZXT H440 Midi-Tower as well? Could also do with buying a thermometer to check the room temperature. To be honest it seems quite cool, seems to be the CPU in games that causes room temperature heat issues :P, cool otherwise, do live in England afterall, always wet and windy.
 
Might be worth trying a different cpu cooler on it just to rule that out. It's possible that the pump is perhaps starting to fail thus not circulating the liquid enough. Have you got one you an borrow from a mate rather than having to buy one?
 
As said your voltage is fine, sounds like it is most likely your cooler or the seating of it, have even heard of people leaving the clear protective sticker on causing this. If you have another cooler you can fit to prove the cooler and seating?

Unfortunately I dont :(. Would need to go out and buy a replacement. Leaving the clear protective sticker on is something I would probably do actually lol... not in this case though, I checked for that yesterday :). The seating is fine I believe *concerned face*
 
Not even a standard intel one? You would have to remove the overclock though, but just to prove it? If not as there anybody nearby that could lend u one?

Hmm, I will go and have a look through the boxes, should have one of those stock coolers actually, definitely never throw anything away that may come in handy.

Will probably also be buying more fans for the case for extra assurance. Could do with someone telling me the best airflow or a better airflow for my case before-hand though :).

If the liquid cooler is the issue how much would it cost to replace for a decent one?
 
The bequiet 240mm jobby is about £120 iirc and that's. A good one.

In terms of case flow have fan(s) at the front i taking and fan(s) at the back expelling so there is movement through the case.

Have you also tried it without the case on? Whilst not a good idea for long term it will at least help in eliminating the warm air inside theory.

I took the front, side and top panel off yesterday, haven't dismantled the whole thing though. Still rises to around about the same temperature in games. Blowing my desktop fan inside the case brought it down a good 20C-25C though :p.
 
That case you're using is not so good for air flow , I actually stopped using mine ( had one about two years ago ) and went to a 750D , and as to that 4790k it runs @4.4 out of the box ( PC set to High Performance ) and with my PC is set to a lower setting ( Balanced) it only goes to 4.4 when I'm in games.
 
May be a silly one but are the fans on you radiator spinning up enough? Is their a possibility that you need to reset the fan curves on your Cpu too? Whilst you may not have the best airflow in that case the fact that your Gpu temps are ok says that you have adequate airflow. I would say it's seems related to your Cpu cooler, so if the fans are spinning up ok and it's seated ok then it's more likely a failing pump.
 
I wouldn't be surprised if the pump has had it or something else has gone awry with the cooler. Unless you are really concerned about aesthetics, all in one coolers are pretty bad.

Something like this Phanteks cooler will be nearly as good as the best AIO but costs half as much, has no pump to make noise and/or fail, and won't leak either.

One way of improving case airflow with the H440 is to remove the mesh strips from the top and front panels.

It might also be worth backing up your current bios, updating to the latest and overclocking manually. Or just leaving it at stock cause it'll boost to 4.4Ghz anyway
 
Those PhaNtek coolers are nice :)...and pretty quiet too :) big though
It's big but the H440 has ample room.

Honestly I have never heard of someone who damaged their mobo cause of strain by a large heatsink. I used an NH D14 for years on an cheap £80 Z68 motherboard without issue including multiple trips in a car between Cumbria and Norfolk.

Will definitely bare all of this in mind by the way, thanks a lot, also sorry for the double quote. I can see myself replacing the front (stock), rear (stock) and cover AF fans in the next few days. With the cooler also to be replaced if I find this to be the fault, looking likely.

Yeah, I was told this years ago :(. Read up a bit more on it recently, found it to be an excellent smaller case though and with the case closed it's silent. Everything in my case seems to be black/orange like the case as well :p. Replacing the case will only happen if all else fails.

They seem to be running fine, I will be replacing those in the next few days though. As for the fan curves those will have always been on default pal. Never messed with those. Yeah as for everything else it seems pretty cool, considering, and the idle temps are okay I guess across the board, in-game temps are also okay apart from the CPU. I have found the Intel stock cooler so will fit that on later and test it with the default clocks, see if that marks the Cooler/pump as faulty.

Thanks for this <3. I believe the current BIOS is up to date? F6 seems to be the last one for 4790K. The F7/F8 both say 5 series, or are these 4790K compatible?

What games have you been trying?

Pretty sure my 4790k is hot, but not that hot!

Rocket League, Overwatch, Battlefield 1, Global Offensive they all climb to the 90's :(. 3 of those games = high framerates so the temps seem to grow quickly :(. Now with the 1080TI in the system I also wanted to play Batman Arkham Knight, Watch Dogs 2, The Witcher 3: Wild Hunt expansions and some of the other unfinished games in my library, issue is these rising temperatures. Seems to be happening on them all.

F7/8 add compatibility for the 5 gen CPUs however they keep support for the older chips too. Right now the first thing I would do is try reseting your current BIOS to default. Make sure you backup your current profile before hand.
