I have read thru all the posts on the topic. But still confused...
Anyways, after searching thru google with hot, hard drive, fan = this post on this forum. Thanks to everyone who contributed.
Just wanted to post some questions here and may be some insights.
I have a PC that hard drives are running too hot (to me.) 2 hard drives stacked on top of each other but are separated about 1/2 inch in between (about thickness of a hard drive. The cage can hold 3 hard drives.) According to Smartfan they are running 47C and 50C. It started going to 52C for the 2nd hd since today where the weather turned warm here (it it 90F or 32 C).
The hard drives have been running in about same temp since I built this PC. Its has smart PSU (with 2 fan and one does not run at all at these temps.) So I added another case fan at the rear of the case (Some cheap case fans that runs all the time.) But this issue has not improved.
Wondering if moving the case fan to the front of the hard drive case would make a difference ?
Following are the results from Speedfan "in-depth online analysis" results from the SMART tab of the program.
This is for the HD that is running at 50C.
