Your CPU cooling setup is indeed doing the job it's supposed to do - the CPU isn't melting into a heap under load. That is why I am blaming the CPU / motherboard, not my CPU cooling. Therefore I feel my CPU cooling setup is doing its job as it should be, the CPU itself is using too much power, thus producing too much heat. It is capble to cool the CPU under 80 when aid64 test, with P1 set to 95W, but not so good when AUTO settings which set the P1 to 120W. I am expecting my setup to cool a 65W TDP CPU not a 95W TDP CPU, or now a CPU using 117W. For Intel test, it stays under 76 as far as I remember. It stays mostly around 77C when running aida64 stress test. I am allowing the fan to go 100% when CPU temp goes over 78C.

I am using the orignal heatsink plus the original fan, additionally, I am using another case fan over it to help. I believe any CPU cooler will have some conditions like that. I mean it's not crashing, it's limiting itself because you've put an insufficient cooler on it, ultimately. It does sound to me like you're expecting to cool a modern hex-core, dodeca-threaded CPU under a heavy artificial benchmark load with a very marginal cooler and wondering why it's struggling. "Some sources state that the peak power for a microprocessor is usually 1.5 times the TDP rating." "The TDP is typically not the largest amount of heat the CPU could ever generate (peak power), such as by running a power virus." If you read up on TDP (even on something as basic as Wikipedia - ) you'll see such statements as: Intel and Asrock will almost certainly say the solution is working as intended (throttling back at high temperatures under high artificial/benchmark load) under the thermal conditions the chip finds itself in. and that any deviations from this ideal set of conditions means you should chose a lower TDP CPU. That you're using the supplied fan (you said you're using a case fan rather than Noctua's fan)Īllowing the supplied fan to run at 100% under PWM control where necessary. Even Noctua themselves say that the cooler is only usable on 65w TDP chips on four assumptions: If you go to Asrock or Intel and say "I'm using this cooler, which has this list of caveats and disclaimers attached to it", they'll point to that and say that's the problem. I would give serious consideration to switching to a different cooler, if the physical dimensions of your case etc permit. The list of disclaimers and comments published by Noctua regarding this cooler is pretty scary: The "problem" is almost certainly with your choice of CPU cooler. this 8700 is more like a 8700k in terms of power consumption to me.
#What is turbo boost short power max Pc#
it is capble to keep it under 80 in Aida64 test if i set the power limit 1 to 95w, and keep the pc quiet. I am using low profile Noctua L9i CPU Cooler with a case fan to cool thr CPU. Howevrer, it looks like either get replacement or switch to AMD platform such as 1700. I am going to contact ASRock raegarding this too. I am seriously suspecting my i7-8700 is defective. i think i have tried all the poosible choice i can think of now. There isnot many things i can chaning in bios. I tried voltage 1.285, ran aida 64, system froze. The core frequency dropped by a lot.Īnother people's 8700 is just using 77 TDP at max. whatever power limit I set, it will hit that when running intel extreme utility to stress the CPU. limit the power limit 1 to 65 W, leave ram AUTO, the max TDP is capped to 65w and power liimit hit is reported.
