CPU running at 98c when gaming. Not overclocked.

[Coptimas]

Hi Everyone,

Recently bought a new build and the ram failed after 8 weeks. Ram has been replaced but I am now noticing through core temp software that CPU gets up to 98c when running TW Rome 2.

The CPU is not overclocked. Details below;

Intel i7 4790k 4.0 GHz Haswell
Stock cooler

CPU fan is spinning and the actual tower does not seem warm, nor is it giving off any heat as my older computers have done in the past. The CPU temp cools down after finishing playing to around 30c within a minute or so.

I am not computer savy and could really use some cost effective advice as I am slightly concerned that the ram failed due to the heat (if that is possible) and that the same may happen to the CPU.

Many thanks for your time and any help is greatly appreciated.

Sounds like the cooler is probably not making good contact with the CPU. While the stock cooler isn't that good, it should at least keep you around 80C at the stock voltage and settings.

There is a good chance that you didn't get one of the plastic pins clicked in good on the cooler to lock it down. Though you might consider just buying a cheap CPU cooler to replace the stock one with. There are several ones that cost less than $20 and have reasonable performance and would even let you do a mild overclock.

Thanks for replying so swiftly. I shall check tomorrow to see if everything is fitted correctly. And if the problem continues I will indeed look to getting something better for cooling. Should I be looking at bigger fans, faster fans, water cooled etc. Once again sorry for the layman's terms but not clued up on these things.

Many thanks

Fans are important but the design of the metal is much more important, and in the low end how loud the fans are tends to come up as a greater concern.

In the end you will want to get one which looks like that. That one is actually known as one of the best so there are lots of ones similar to it. The copper looking tubes you see are filled with a liquid (varies from one to the next on what the liquid actually is). So the pipes at the bottom get heated and the water moves and transfers the heat up to the large metal block at top. This design is highly effective at cooling CPUs, which helps minimize the importance of fans. Fans are still needed, but just about any fan will do. Only reason I don't just straight advise the one I posted above is cause unless you plan to overclock you can save a few bucks on cheaper similar models.

There are several but there are two more of the cheaper ones for comparison.

That is something that I will consider but I am a little perplexed by all this. I have investigated the fan, which was working, and I have made sure that everything fits. I am now finding however, and this may be the route issue, that when I check the core temp program I downloaded to monitor the situation I find it says my processor is running 4.4, when it is only a 4 gig CPU. I have also checked in bios and in one area it states it is a 4.00 gig CPU but at the front where it monitors temp etc it say 4.40 gig.

I am now a little stumped as it appears that the CPU is overheating, and that the computer has set Overclocked its self??!!

I would really appreciate further advice as messing about in bios etc is not my cup of tea.

Many thanks again

Your CPU is working normally.

What you are seeing is what is known as Turbo Boost. Basically the idea developed as a result of multi-core CPUs. When all of the CPU cores are turned on and working in most CPUs, the power consumption increases to max, as does heat and so the CPU typically sits at its basic speed, which in this case is 4Ghz. However, when only one or two of the four cores are being used, the amount of heat and power being used is significantly reduced. So the PC is able to increase the clock speed of that one or those two CPU cores in order to improve performance for that program. This is a very helpful feature since there are lots of programs still that only use one CPU core or only use two.

There is a bit more to it than that, but that is 90% of all there is to it. If you check the link I sent above, you will see that it lists a max turbo frequency of 4.4Ghz so your CPU is running normally. I would say most likely your voltage and everything is set normally also. Since your temps are still high, I would say your best choice at this point is to buy a better CPU cooler. I know the Intel stock cooler was enough to keep an older and should be hotter CPU core running below 80C at full load, but there are some new innovations in the CPU you have that could cause the cooler not to be sufficient anymore.

Please take a look at this thread as it states that this is an on going issue.

As such I think I may have to get a refund and get a different CPU. Which other CPU's are comparable or better?

Many thanks again

Hi,

So still having issues. As already stated I have lost one set of RAM on this build, I have followed all the advice and still the CPU is running hot. Being a novice I was not aware that RAM could effect the CPU however it would appear from my reading that it can.

I now find that BIOS, CPU-Z and Intels extreme tuning utility are all telling me that my RAM is 1366 mhz instead of the 1866 mhz that I purchased and is in the motherboard.

I have tried to set it manually in BIOS at which point it BSOD'd.

Could this be the issue?
Also why is the RAM not being recognized at the right frequency?

I have checked and the motherboard is compatable and so is the CPU.

I really am stumped...again.

Any help really appreciated

Hello, Sorry I am off traveling so don't have a lot of time to help think of another solution, but no the RAM is not the issue. The RAM does directly effect the CPU in several ways, but in terms of effects it can have on power and heat are too limited to cause this kind of problem.

For your RAM frequency, almost all RAM runs at 1333Mhz/1366Mhz out of the box. You use predefinied memory profiles in BIOS to set it to the proper setting. So when you set it, it will make the RAM run at the right settings for 1866. The reason it BSODs when you change it manually is because there are other variables that need changed you are not changing. It is possible the RAM is defective but likely its fine.
