Quick cooling question

post #1 of 4
Thread Starter 
Sorry for a noob question. Does CPU efficiency/performance vary when the chip is cooler or not? Like, if I place a big cooler on a cpu running at 100% and it is a few degrees cooler than a small cooler on that cpu running at 100%, is the colder scenario better performance wise? Thanks!

No.

The only time this will happen is when your CPU reaches TJ max and downclocks the multiplier, in which case your CPU will run slower, but cooler.

But if your temps are below the TJ max, they will run at the same speed regardless the temperature.

Alright, thanks man. So I shouldn't bother with huge fans as long as I'm not reaching max? And does this concept apply with other components, such as a gpu(sorry if off correct forum now)?

The concern isn't so much whether you get the same performance at different temperatures. It's more so prolonging the life span of your components. On top of that is user preference too. I personally don't like my CPU reaching 90c even though by Intel's spec it is a safe temperature, and my CPU still operates at full speed.

The same concept applies to GPUs, yes. Except the overheating prevention mechanism in GPUs are slightly different. I know for my AMD card, at 90-92c it will downclock to a speed between 2D and 3D clocks. Not sure about Nvidia

Even though, I still suggest you invest in better cooling to keep your temps down.
