February 6, 201016 yr I have an old Dell Optiplex GX 620 that I am using to test out unRAID. Love the fact that I can use all my free old equipment and upgrade as I go, great flexibility. I have 1 HDD floating unmounted in a 5.25 optical bay sitting on top of a unused DVD drive, 1 screwed into the 3.5" FDD slot, and 1 in the normal slot (bottom of the front grill the teal blue stock HDD mounting bracket peeking through). (see attached pic) Well during parity and long transfers these suckers heated right on up to 47 degrees C (ambient is 20.5 C)... I did some searches and that sounded pretty bad, so I promptly opened the case and stuck a small house blowing on it for the time being. seems to have stabilized at 33C. Looking for opinions on a cheap satisfactory way to cool these things. would something like this work: Option 1 (cleaner): 2x http://www.amazon.com/Drive-Cooler-Fans-fits-5-25-Inch-Silver/dp/B000YIWPA6 one in each 5.25" slot 2x ~60mm fans to cool part of the stock HDD enclosure (though still not ideal.. I have a 2 3/8" by 5" grate above the stock HDD mount where i can place them) Option 2 (ghetto fabulous) -Leave the optical driver bracket/cover completely off the front of the case and attach/zip tie/superglue a 140mm fan infront on the optical and FDD drive bays -Zip tie a 80mm fan to the bottom of the front grill to cool the stock HDD drive locations Option 1 is cleaner but would only cool 3 drives Option 2 is ghetto but would cool 5 drives (2 in optical, 1 in FDD, 2 in the stock lower grill area) if/when I upgraded to Plus Thoughts?
February 6, 201016 yr Author Forgot 1 more thing... is there a strategy I should be following for assigning drives based on airflow of its physical locations. IE areas with crappy airflow should (not) be parity or drive 1/2?
February 6, 201016 yr if you plan on using that case then it is pointless to have the DVD drive as it will not work in stock unRAID. If you want to cool the drives I would suggest going with something like this.
February 6, 201016 yr Author The DVD drive is only there as a spacer in between the HDD in the FDD slot, it is not even plugged in. It will be removed when I have 5.25 mounts for my HDD. ... Just uncovered the fan documentation here http://lime-technology.com/wiki/index.php?title=UnRAID_Topical_Index#Fans looks like I have some reading to do
February 8, 201016 yr They do have 3in2 brackets with fans on the front. When you grow past 3 drives, may consider getting out of the ghetto.. LOL I would not buy those 5.25 coolers from amazon. I've had them, when the fans start to get old they will get noisy. Better to get something you will use for a while after. I've had this cooling 2 10,000 RPM SCSI drives for years in a dual xeon rig. Works great with the right fan. http://www.newegg.com/Product/Product.aspx?Item=N82E16856999209 http://www.istarusa.com/rackmount_chassis/accessories/rack/tc-istorm7.aspx?AspxAutoDetectCookieSupport=1 Maybe you can find a used one or something similar on eBay.
