ATi HD 4870 idle temperature too high

Hello! The main reason that’s kept me from installing a Linux operating system on my desktop pc used to be that my ATi HD 4870 idle temperatures used to be insanely high - usually over 70C. Hearing of the new power management features in kernel 3.11 I got very excited.

Hoping the temperature issues would be a problem of the past I installed the new openSuse 13.1 and enabled DPM (by adding ‘radeon.dpm=1’ to the optional kernel options line in the boot manager). The OS booted up nicely and dmesg showed that dpm had been initialized. However, using sensors (or the kde temperature monitoring widget) the temperature is still 80C in idle.

Am I doing it wrong?

You have a running fan and heat sink?? maybe you need to reapply the silicon grease to the heat sink. You over clocking?

80 C is way too high you will burn out your CPU

Of course.

You over clocking?

No.

maybe you need to reapply the silicon grease to the heat sink.

Cleaning and reapplying the thermal paste would be a good start and I will try to do the job in the near future. However, I won’t believe for a second that this will bring a 30C degree drop in the temperature. The card has been working steadily at ~48C under Windows for a few years at 30% fan speed showing no sign of overheating.

Then run top and see if you have some process that is using a bunch of CPU. What desktop?

ATi HD 4870 is a GPU not a CPU, afaik top does not monitor GPU usage. Running KDE.

OOPS Should read closer LOL

What driver?

Default open source radeon driver. The whole system is running on default settings, haven’t messed around with it besides enabling dynamic power management.
