CPU getting too hot

Hi Everybody,

 

My CPU is running way too hot when playing games; it will get to 75 C with an old game and with FIFA 17 it will reach 90 C,

funny thing is it will not throttle and shut down but instead carry on working...

 

I've cleaned the interior of the case, purchased a beefier heatsink and applied a good thermal paste to no avail ... I was googling and read about things like: reducing the frequency multiplier of the CPU speed and altering the vcore voltage in BIOS; what are these? is anyone able to help me? 

Thank you in advance.

 

My OS is Windows 7, 64 bit, Home Edition and my processor is an i7 2600K

Hey, reducing the frequency multiplier in BIOS basically means under-clocking your CPU, so that it works slower, but at a lower temperature. Unfortunately, I don't know what the Vcore voltages are or why your processor is getting this hot even though you've done everything possible hardware-wise to prevent that. All I can advise you is to wait for a more knowledgeable reply and also to try restarting your PC before playing games, such as FIFA or Football Manager, waiting 1 minute after you've turned on your computer and then starting the game (So, that everything else is closed and your PC is only tasked with playing the game after you've restarted and everything has booted up properly). By the way, how are the other things with the your PC going, any other problems besides this one?

How are you obtaining the temperature reading? I would question its accuracy if you are not seeing any adverse effect from temperatures supposedly that high, and improved cooling hasn't altered them.

All other things seem to be fine, when browsing the internet I get 45- 50 C  :-)

I'm monitoring my temps by keeping CPUID HWMonitor on.

Utilities don't always read temperatures correctly. Is there monitoring software supplied by the manufacturer of the system mainboard? Otherwise, when the temperature is reported very high, if you reboot and immediately enter the BIOS setup and check the temperature reading there, is that consistent with the readings of up to 90C? The CPU will cool somewhat in the time it takes to reboot, but if it showed very much lower, then when you restarted Windows it was higher again, that would suggest CPUID HWMonitor may be misreading the temperature.

I'd guess it's misreading as well.  If you check cpu-world.com or the manufacturer's spec sheet for the processor in question its maximum is just below 73 degrees C.

 

I know that these temperatures are always well below critical, but they're generally not 20 degrees C below critical.

I'll check the temps by using another software (Piriform Speccy to be more precise), I can't however do the BIOS things, I mean, I CAN but it's pointless because the temps drop like 30° (down to 60) the very moment I quit the game.

Speccy is even less reliable to report correct temperatures than CPUID HDWMonitor.  The most accurate readings you can get from the computer are in the BIOS. 

_{Ok, here are the readings:}

 

_{I used three software programs at the same time: CPUID, Speccy and RealTemp GT; Speccy only displays the temp at any given moment, it does not record the highest and lowest temps, so when I Interrupt my game for a quick check, it displays 75 C, which is not alarming because, as I said before, I test it with the game FIFA, which is known to be cpu demanding; the other two display slightly higher temps (both give the same temps) now where it gets interesting is the highest temp recorded, BOTH CPUID and RealTemp Display 90 C  which is way too hot!}

_{It cannot be that those two pieces of software are wrong.}

 

_{Anyone any ideas?}

 

_{PS: 90 C  = 194 F}   

Speccy is even less reliable to report correct temperatures than CPUID HDWMonitor.  The most accurate readings you can get from the computer are in the BIOS. 

It may be so but it's pointless because I cannot play and be in BIOS at the same time and, as I've said, the temps drop way too quickly!

What heat sink have you fitted?  Is it making good contact with the CPU?

I'd imagine so, but opening the case (again) and messing with the heatsink (again) which would imply unscrewing and removing the motherboard (again) is, at this time, my last resort as I'd like to try all software (possible) issues before moving to the hardware.

Why would you need to unscrew the motherboard? Can't you just open the case when the computer is working, see if the fan spins properly and if it does, turn off the computer. Then, place your hand on the fan and try to wiggle it a little bit - if it can be wiggled easily, then you'd need to unscrew it, clean your CPU, place new thermal paste on it and screw the fan back on, but this time tightly. If it can't be wiggled, then there is no problem with it hard-ware wise. Since the case is opened either way, quickly also check whether your video card and everything else is well dusted off and properly connected. Then, screw the case back closed and at this moment if the temperatures are still high and we can't think of a software-related issue, that means that your CPU is probably faulty. If such is the case, then you'd either need to replace it or return it and get another one.

I would not conclude such, since it's the sensors which convey any indication of temperature.  The CPU can be functioning properly but there are any number of circumstances which might cause incorrect temperature readings.

 

I would suspect everything else...fan/heatsink, thermal paste, sensors to motherboard...before I would think "CPU".
