Question My cpu is reaching 75 - 89 while gaming

[Breaking431]

Hi all so i recently overclocked my cpu i7 6700k from 4.2ghz to 4.6ghz , i noticed a jump on the temp on a stock used to be 69 to 75while gaming , now with overclocked , it reaches 76 to 88 , my question is i know that last time i out thermal paste really long time ago probably a year ago , should i apply a new paste? Or i just leave it like that? And no worries
Thanks in advanc

What model cpu cooler are you using?
Can you show a photo of your system with side panel removed?

If you're using Intel stock cooler, then it is not suitable for overclocking.
Get a decent heatpipe tower cooler instead (at least 4 heatpipes).

Its a corsair a1225m12s
Its 2 fans actually on the right side is corsair
And on the other side is cougar ,but the cougar fan is not working , it always shows 0rpm on bios it just run very slow , i tried unpluging it still no luck

Sure can do

Its also an onboard , i didnt have a case cuz i traveled , so i have it on acardbooard for abit of time but anyway this is the heatink

You are good.
Overclocking does increase temperature.
But the processor monitors it's own temperature and will slow down or shut off to protect itself if it senses a dangerous temperature.
That is 100c.

Cheers dude , so should i apply a thermal paste? Also does 88c cause fps drops ? Or it doesnt matter

I'm having difficulty finding the maximum temperature rating of the i7-6700K. It's not mentioned on the Intel Ark web page I visited, nor is it stated in CPU-World.com, as far as I can tell.

There are numerous postings on Tom's and Reddit about safe overclock temperatures for the i7-6700K. Some people say up to 90C is OK, other's prefer 80C max.

This stress test on an i7-6700K (presumably not overclocked) reached a peak temperature of 73C.

The Intel TDP rating of your CPU (not overclocked?) is 91 W.

The Intel Thermal Solution Specification of your CPU is PCG 2015D (130W), (not overclocked?).

Hence, at the very least, as far as I can tell, you should be using a cooler rated for 130W at stock settings. I don't know how much power the CPU is dissipating with your overclock, but it might be more than 130W. Try running CPUID HWMonitor (or similar) and see what the CPU power readings are.

Looking at your heatsink and bearing in mind only one fan is working, I'd personally upgrade to a much bigger dual-tower dual-fan cooler such as the Thermalright Peerless Assassin 120 SE. The extra mass, two more heatpipes, increased surface area and two working fans should improve temperatures.

You'll knock a few degrees off your maximum temperatures with a more capable cooler.

so should i apply a thermal paste?

The only time I repaste my CPUs is when I take off the heatsink. Some of them have been running untouched for years.

does 88c cause fps drops ?

Possibly, especially if the CPU is hitting the thermal throttling point. I've no idea if the GPU or the CPU in your system is the bottleneck. The fps limit might be due to the GPU, not the CPU.

Only way to tell at the same overclock is to improve the CPU cooling and reduce the temperature by 5 to 10 degrees. If you get improved fps, you'll know the answer.

Thank you so much for ur time and info , thats helps actually , as of upgrading to a new cooler would be my next upgrade , well the temp is not reaching 90c , will close to i guess , why i thought this is a thermal paste problem is because 6 month ago with 1 fan , the temp doesnt reach above 65c while gaming , thats why i thought i might re apply thermal paste

Also im not experience with heatsink and stuff as my heatsink you can remove 1 fan if you like my question is can i get 1 fan and apply it to the other side of the heatsink as one is not working? Like for example this one

Thermalright BLACK ARGB CPU Fan 120mm 4pin PWM 1500RPM S-FDB

Thermalright TL-C12Cb BLACK ARGB CPU Fan 120mm 4pin PWM Case Cooler Fan, 4pin PWM Silent Computer Fan with S-FDB Bearing Included, Up to 1500RPM Cooling Fan |

Yes, adding another fan (the make isn't important) should bring the temperature down by a degree or two, but you would see a bigger improvement with more heatpipes to draw the heat away from the CPU. Just make sure you fit the second fan to blow air in the same direction as the first fan.

That's why I suggested a dual tower Thermalright cooler with 6 heatpipes. They do an even larger cooler with 7 heatpipes for a few dollars more. You'd see a bigger drop in temperatures with a larger cooler and more heatpipes.

As for changing the heatsink paste, go ahead, but unless you applied too much or too little, or it's "pumped out". I doubt it'll make much difference. Remember not to apply too much paste. A small blob the size of a pea (3mm to 4mm diameter) in the middle of the CPU will spread out and cover the heatsink when you screw it down.

You just need a bigger air cooler or a good sized AIO (at least 240mm) to get rid of the heat more efficiently.
