cooling issue

[quayyum94]

i'm currently using intel core i7 8700 with a cooler master 120mm aio,whenever i play regular games the temparature spikes upto 84 degree,but in two games like gears 5 and nfs heat,whenever i play these two games the temperature hits around 95-100 degree celsius,is it a game issue or my aio cant cool my cpu in heavy intensive games,plz suggest me shall i change my liqued cooler from 120mm to 360mm or shall i clam warranty for a cpu replacement?

Its a hot CPU.  I run a 65w CPU on a 120mm AIO and it does fine, can even mild OC on all core but quickly the AIO loses out.  I have mine in push/pull config to help its little radiator along.  I would recommend first checking your thermal paste, clean the radiator, and ensure no bubbles in the pump/block before replacing.

120mm is really low for watercooling but it shouldn't go that high either, what case do you have ? The airflow is maybe poor.

i did both changed the thermal paste and cleaned the pump as well but didnt worked out,case-cooler master mb500,2fans for intake in front and 2fans for exhaust in top and the 120mm in exhaust position!

Can you add a second fan to the radiator creating a push/pull which will slightly decrease the temp of the water in the loop while in the heat exchanger (rad)?  This will help with temps a few degrees for sure.

 

You could also look to undervolt the CPU and see if its still stable, which will vastly increase temps.

 

If not I wouldn't hook anything less than a 240mm rad to that CPU personally.

well to be honest couple of degrees wont be much bcz in both the games nfs heat and gears 5 it reaches 100 degrees,its a locked cpu and all the voltages in bios r in auto so any other suggestions?

Mount as intake so its getting only the coolest ambient temperature to reduce the heat in the radiator, rather than recycled heated up air from inside the case (in its current position as rear exhaust) - easiest way to test this is just take it off as rear exhaust, leave side panel off and let it sit outside the case doing its job and see if that helps (using ambient temps) - if it does, a second fan will help also.  I also highly recommend TG Kryonaut as thermal paste, as it drops temps 3-5c in all applications I test.  

 

The real fix is a better cooler for that hot CPU.  Its typically recommended (when running higher end components) to use 240mm rad per item (I.E. 1x240mm rad should handle any consumer CPU without an OC.  If you wanted to add a GPU to that loop it would be typically recommended to run a second 240mm rad.  I have ran a CPU and GPU on 2x80mm radiators before, but that was a 77w processor and a 130w GPU.

 

In my case, I have 2x240mm and 1x120mm rads on just my CPU (cause OC madness) - not even a 240mm rad could keep any decent OC on my chip (AIO) so had to build a custom loop.

thnx will try and let u knowm,also if u have any better ideas plz let me know!

Sounds like the pump is dying.
