tempest toast Jun 10, 2019 @ 12:39pm
Average idle temp i9-9900k OC@4.98 ghz
Searched google but everyone is having diff temp give or take couple degrees. I idle at the low 40s and during games some cores can get as hot as 85. (I have a Corsair aio 360mm. Are these temps too hot?)

No that seems about right considering the overclock, the i9-9900K is known for getting very hot when overclocked high. People have their own preference at what they consider an acceptable temperature under load, but if you ask me 85°C is fully safe as long as it doesn't go much higher.

85C imo for games is quite hot but not to hot. The chip is fine up to 93C where thermal throtteling starts. At 100C it comences an emergency shut down.

Have you tried to lower voltages already? Otherwise delidding and Die lapping will highly reduce temperatures but the Die lapping in unexperienced hands is kinda dangerous.

Thats TOO hot. I bet you have one of those crappy Asus motherboards with the 4phase power dont you? My buddy has a Asus board that was like $350 or something when new and his i9 runs HOT and its on CUSTOM LIQUID! I have an i9 9900k in an MSI gaming edge AC mobo and it runs 55c ingame using the corsair H150i the 360mm like yours. Get rid of that ASUS board asap and get a brand that used proper power delivery and doesnt have buggy microcode and bios. Grab an MSI board or an ASrock board.

It might be "safe" but overtime your CPU is degrading much faster than if you were chillin at 60c or so ingames. running 85 all the time is going to wear that I9 down and make it slow, notice how laptops always get slower after a year sometimes 2 if your lucky? No matter what you do its the CPU degradation from being so hot all the time.

Why? What are you talking about? Having only 4 pins for power would deliver enough power to run a 9900K stable. Besides it wouldn't run hotter because of that but colder as you have less power.

A CPU is no degrading by high temperature which is far below the limit but spiking temperature.

So what are you talking about? You just guessing into the blue with technical nonsense any PC professional can call out easily.

PS: laptops CPU don't degrade after a year. It mostly dried out thermalbpaste that causes thermal throttle. Repast and you get old performance again.

85 degrees under load (a CPU demanding game) is not a cause for concern with an i9 9900K. When the BIOS temp reaches 100 degrees the PC will want to shut down but mine has been between 95-100 before and I've had no sign of throttling. It is a very resilient but very hot CPU. The most I've had out of mine since fitting a Corsair H100i is 82 degrees and that was editing a video at 1440p which put the load up to 97% which all things considered, a very good temp.

Where is your radiator located? I assume if it's a 360mm then it's as an intake? If you're super concerned then you could repaste or adjust your fan curve so it's slightly more aggressive.

Do you get any performance difference between stock and oc? Benchmarks that I have seen show no difference due to gpu bottlenecking.

Performance difference will vary from application to application. Some are GPU heavy in which an OC'd CPU wouldn't make much difference but some are CPU heavy in which an OC would make a difference.

This reply is a logical reasoning error called The Appeal To Ignorance. Things must be true or false. The reply hasn't provided any evidence, just a plausible statement, so most readers assume it must be true. And it didn't answer the question.

Well I guess I didn't personally answer your question... but it's hard to. If I am playing something CPU heavy and I'm overclocked then yes I see an improvement. Otherwise I don't. Thought that was pretty straightforward from my response but I guess you always get those who want to correct others.

I thought it answered your question, improvement in some application, nothing in others depends on where the bottleneck is.

So it is true for some application, false for others.

You mentioned you seen benchmark that shows no difference without providing any evidence, yet you are complaining about people not providing any evidence?

It is the norm that forums like this provides personal knowledge with no testing or evidence are provided. It is also true that these places has some incorrect fact, but you are asking a question on internet forum and that is the norm.

If you want evidence, ask for it up front.
