Question / Help High CPU Usage

Hello Community,
everytime when i streaming, my cpu usage goes about 95%-100%. And my CPU-Fan is also pretty loud.
I currently stream FPS and MMORPGs, like Battlefield 3 or WoW in Game Capute only (I never used monitor capture). Does the High CPU Usage hurts my CPU after a while?

My Computer:
50MB down / 2.5MB up
i5-2500k@3.3GHz
Asus GTX 660 TI

Stream is downscaled by 1.5 (1280x720) from 1920x1080.
Hope you may help me to improve my stream experience.

Sorry about my bad english :)


And ye...heres the log file:

The log seems mostly fine. Have you ever considered simply lowering the game's own settings a bit? "Modern" videogames are really hard on CPU and GPU, toning the settings tone even just a little might drop the CPU usage down quite a bit actually.

Settings you'll want to keep maxed are things like Texture Quality, Resolution (in-game), Framerate. Everything else can be toned down a little without hurting the stream quality.

Thanks for the quick reply.

I currently playing "Blacklight Retribution", its a FPS games and it needs about 60% of CPU. OBS needs 40% for rendering or other stuff, idk. i've tried to change the quality setting in the game, also in other games but it makes no difference. even not when i only stream with 30fps.

i mean my game or the stream isnt stuttering, but i'm scared if the high usage will damage my chipset.

nothing special had the i5 2500k at 4,5ghz its actually using that much cpu when you stream 720@60 go with the 720@48 settings kharay got in his guide i guess else you wont get any room on your cpu and as long as your cpu doesnt go over 98°C you'll be fine but if it reaches the temp it will throttle the cpu down

no matter what boxed fans are bullshit they are loud as fuck and only do the necessary cooling work on the cpu

Just keep an eye on its temperature. Use something like this to keep an eye on it during load. A high usage does not necessarily means its temperature gets to damaging levels.

Anything below 80 degrees C is tolerable. Ideally you'd obviously want it lower but, well... maybe you just have a poor cooler. If you do, consider replacing the cooler with something with a bit more punch. If you research the topic you can actually get some really good cooling going on air alone. My cooler sees my CPU at 50 degrees C at the most, on a hot day... during load. And that is on air alone. Imagine it on liquid cooling.

Hey thanks for your reply.

So you say when i buy a better and quieter cpu fan, it doesn't matter if the cpu is almost maxed out? The noise is annoying

Again, if the temperature remains at a reasonable level it's fine. CPUs were made to actually be used, so, 90% load is fine. As long as the temperature doesn't get to the same number. ;)

Haha ok :) Thank you guys. I will test my stream now and keep an eye on the temperature. I will post the results later :)

80 degree :) Fan is still loud like a screaming mom but it passed with music till i have a new fan. Question: which kind of cooling do you prefer? Or do you recommend a specific cooler? Let me know (if it costs less than 100 euro :D)

yep noctua is sick ....

i got a thermalright macho 120 cooling my i7 2700k@4,2ghz at idle to 21-26°C and under gaming+streaming load not over 60°C so far and the fan is running at 15-35% ;D

they are both actually quite cheap but they are highend cpu aircoolers

make sure it fits into your case if you go for an high end one because the heatsink itself is freaking huge


they also offer smaller ones which do the same work but are not really good for oc but still decent to get something around 4,2ghz on an i5 2500k without much temp problems but on stock they will do good

its possible that some ram modules dont fit under them

you can change the multiplier on bios no matter what chipset you use as long as you got the k version of the cpu

No thats not true, dude.
A H67 Board allows only 33x multiplier.
You can only overclock with a Z68 or P67 Board.

So, i will buy:
GigaByte GA-Z68AP-D3 for OC
Noctua NH-U12S CPU-Cooler or the U9B SE2 idk
