Higher temps, and new monitor ?

post #1 of 4
Thread Starter 
I just bought a 120Hz monitor, and i see higher temps now, in idle and games too. Is this possible to get higher temps if i use the monitor on 120Hz ?
Also changed the PSU with a enermax revolution 750W, could also the PSU influence the temps ?
Temps, gpu and cpu.

The CPU stood some time ago in idle a 33 degrees, now is on 42 degrees.

    My guess is that your new PSU is moving less air than the old one, thus increasing your case temperature, which will cause an increase in idle CPU and GPU temperatures.
    I don't know if there is a link between your refresh rate and temperature or not.  I would be curious to know if the higher refresh rate is affecting CPU usage/temperature.  If your 120 Hz monitor also supports 60 Hz, you could try temporarily changing the refresh rate down to 60 Hz and see what happens.

Is the new monitor a bigger resolution? Might be more load on the gpu if it is.

Pretty much what $ilent and Techie007 have said, if your new monitor is a higher resolution or refresh rate you will probably find that your GPU memory clock sits higher at an idle (desktop) than it did with your old monitor..

If you GPU is hotter and exhausting hot air into your case it will effect your CPU temps as well.

Same issue when running multiple monitors.. I vaguely remember people trying to edit the GPUs BIOS to make it sit at a lower memory clock - however wouldn't recommend this as it tends to fail miserably more often than not.

TL;DR: Get more airflow through your case
