I have an HP 6305 Pro with an AMD A4-5300B processor (which features AMD Radeon HD 7480D integrated graphics). It is my understanding that it is not good to allow this CPU to get over 70 degrees Celcius. However, when I opened Speccy to look at my CPU temperature, I saw that it fluctuated between about 50 and 72 Celcius. It seemed to stay in the 60s most of the time, but frequently climbed into the 70s. I then stopped JDownloader (which I had running some downloads at the time), and it dropped significantly, staying mostly between 47 and 58 (with occasional climbs into the 60s), staying mostly in the lower 50s. However, it is my understanding that even this is fairly high for an idle temperature.
It seems to me that whenever I use even a moderate amount of CPU, my temperatures climb very high. I recorded a video of my Windows Task Manager and Speccy open side by side, so you can see how much CPU usage tends to correlate to what temperatures of my computer. Here's the video:
I'm now starting to think that the fan might be the cause. No matter how hot my CPU gets, the fan is always quiet.
I booted into the BIOS, and tried adjusting the "Fan Idle Mode" speed setting* (without saving the changes - just as an experiment to see what would happen). Even on the highest setting, the fan didn't get any louder. In contrast, on my old computer (an HP 6005) setting this BIOS option to the highest setting immediately made the fan run so loud that it sounded like a hair dryer. Unless something is different in this computer's BIOS and the fan speed changes don't take effect until they are saved or the computer reboots or something, it seems that the CPU fan on my new computer just doesn't speed up.
I could be wrong. I'm not 100% sure that the fan is the issue (or even whether the fan's seeming refusal to speed up is an issue with the fan itself), and I don't know of any better way to test the fan.
Do you know of any way that I could find out?
* I'm speaking of the setting seen in this photo from the HP website:
