i7 iMac HDD temperature problem
I've just got my new 27'' iMac with i7 CPU / 4GB RAM / 2TB HDD
Now I figured out that the temperature of the 2TB Hitachi HDD is quite high.
At idle it's about 47°C. During a CPU stress test it climbing up to 59°C !
The ambient is at 16°C.
The default fan speeds (temps) are:
1.000 RPM OPD (36°C)
1.100 RPM HDD (47°C)
938 RPM CPU (40°C)
Under the stress test they are:
1.000 RPM OPD (44°C)
1.550 RPM HDD (59°C)
1.860 RPM CPU (63°C)
I've tried to use SMCfanControl and speed up all fans by +250 RPM. The CPU and the optical drive temps reduced about 2° - 3°C while the HDD temps stays that high. I than turned the HDD fan up to 2.000 RPM which didn't change anything.
Now, about 30 min after the stress test, all fans drops to normal as well as the temps. Except the HDD... while the fan is back to 1.000 RPM the temp is still at 58°C.
I wonder how long it will take under this conditions to fry it... spring and summer are still yet to come...!
Are there any tips and/or hints around here?
Thank you in advance.
