help, new to pc building and think my cpu is too hot

[Naxi_Mu]

so i Ooverclocked my i7 7700k using an XMP profile, runs at 4.8 GHZ but when i run aida64 it starts to thermal throttle, max about 28% avg. of 5-10% fluctuates every time i run it, i have an AIO on it, but its kinda cheap a Kraken x31. 

 

At idle it runs at about 30-45 degrees Celsius, and under-load it hits 100 on the hottest core

only thermal throttles when under 100% use, so during video encoding and rendering

 

is it okay to keep it like this or should i take mesaure to reduce tghis? if so how? 

 

thanks for any input you can provide

relid your cpu with liquid metal or better thermal paste, sometimes one core is hotter than others because the TIM doesnt cover the whole die

[Hiitchy]

You're overclocking with a radiator that only uses 1 fan. If you purchased a 240/280/360mm radiator with dual or triple fans you'd have much better cooling.

 

The x31 only has so much fin density and one fan the heat isn't being dissipated from the loop, at least not effectively.

Bad cooling and bad chip. Of course it will hit 100

He could try sandwiching it between two fans in a push-pull config for a bit better cooling, but I agree that a bigger rad or maybe a beefy air cooler is better.

delidding will help a lot AFAIK.

Agreed, but It's been my experience that doing that will yield poor results, hence the suggestion to up the radiator size, either that or just go back to air cooling

a noctua nh d15 is like 3°C cooler than a good 120 rad

You should first start by lowering volatage and clocks slightly as your AIO isnt keeping up with the heat. also i wouldn't recommend delidding as the risk isn't worth the minor temperature improvement. I would recommend buying some good thermal paste such as arctic silver 5. You might need to lower your overclock a bit due to the fact that you are still limited by your aio radiator. Also you whilst in a aida 64 run you should expect temperatures to be up to 80c when overclocked.

I would probably  get rid of the XMP profile and oc manually. It will take longer but if your aio (even though its a 120mm) cant cool it then your voltage is too high. This will give you far better temperatures as your voltage will be more stable and at a level your aio can cool. also i wouldn't recommend delidding as the risk isn't worth the minor temperature improvement.

XMP is for memory, it has no impact on CPU

Oh right yeah lol got a bit confused by "overclocked my i7 7700k using an XMP profile". but he still needs to lower the voltage

maybe you should settle for a lower overclock atm until AIO upgrade or as other suggested, until you decide to delid the CPU
