Is it bad to run your CPU warm?

post #1 of 11
Thread Starter 
I am currently using (Gigabyte's) Easy Tune 6 to control my fans, in my sig rig and HTPC.

I was wondering if it is bad to have NO fans running until the CPU reaches 40 degrees Celsius. They then aggressively increase to 100% PWM at 60 degrees Celsius.

A side question is, what is a safe operating temp for the GTX770 ? I know the older GPU's would happily reach 90+ Celsius on reference cooling. Is this still current ?

Wouldn't have though it would be a problem, other than it will get to 40*C very quickly.

Also my own gtx770 idles at around 30-40*C and runs games at a solid 80*C. thumb.gif

It shouldn't be a problem at all. I use Asus's AI Suite to shut off all fans when CPU temp is <40C, and then to run the fans at ~5-600 RPM until the CPU temp gets to 55C, at which time all the fans gradually ramp up to max RPM.

With it set up like this, my system is nearly silent most of the time, and the fans only rev up when I'm doing something CPU-intensive.

Currently around 20 Celsius ( 68F)

But come summer, 8 months or so, it can get up to 30 degrees Celsius (86F), even with the AC on devil.gif

I would reapply the tim on your cards,and the 770gtx being reference should be at 80-85c not more (unless you have a bad airflow oryou have your card oced or you have cards in sli )

Which is your case?which is ypur fan setup?which is your cpu and gpu cooling?

Sounds good to me for a video card.

I have a Alphacool NexXxoS XP3 for my CPU and a Alphacool NexXxoS NVXP for the GTX770, both have Arctic Silver 5 TIM used.

The coolant, Mayhems X1 UV Emerald Green, is pumped around by a D5.

Temperatures are high for.a watercooling system(if yoyr 770 reaches 90c)

s I dont know how good is the radiator/pump maybe is better than a midrange heatsink.then I would change the coolant/TI

Test your temperature with aida64
