propergol Posted October 10, 2015 Share Posted October 10, 2015 Some picts of my quick but functional SAS expander mounting A very efficient 350W TFX PSU : SAS mount : Mounted in the case. The setup isn't complete yet (but working). When completed it would have 1x 240GB SSD + 3x240Gb caching SSDs, 6x4TB + 3x5TB HDs : virtualy 39TB with SSD write caching x3. On this picture I was testing dual link between the M1115 and Intel SAS expander : Single link : I need some more work on cable management... But cooling is now perfectly tunned with SpeedFan that controls 5 case fans. HDs are between 29°C and 34°C and both SAS card's CPU below 45°C (thanks to a case fan puching air between both SAS cards).

0 propergol Posted October 18, 2015 Author Share Posted October 18, 2015 Small update : I did replace the original heatsink with a bigger and 100% copper one. I did fixed it with Arctic Sylver Thermal Adhesive, so it's permanent but much more efficient than thermal paste in this case. Then I did bended the heatsink pins one by one. The result is an impressive 20°C temp drop from 45-50°C to 27-30°C. I plan to do the same for the top M1115.

0 Christopher (Drashna) Posted October 19, 2015 Share Posted October 19, 2015 Very nice! And it looks like you're very used to modding stuff! Quote Link to comment Share on other sites More sharing options...
0 propergol Posted October 19, 2015 Author Share Posted October 19, 2015 Thanks. Yes, after 10 years with watercooling cases (some were dual Xeon), I am now only doing air cooled stuff and even if its more challenging regarding temperatures, its way cheaper... A good controled air flow with positive air pressure can cool a lot of setup, with near to zero maintenance. Now that I use DrivePool, I would be able to keep the same case and if I need more data room, only change 4TB drives as price drop with 8TB, one by one... 72TB in a small mid tower with all HD under 35°C Christopher (Drashna) 1 Quote Link to comment Share on other sites More sharing options...
0 Christopher (Drashna) Posted October 20, 2015 Share Posted October 20, 2015 Water cooling is great, if you never plan on changing stuff. And yeah, air cooling is much simpler. And for the post part, there isn't really a huge gain one way or another. And yeah, I definitely agree with you on the hard drives. Though, I'm using a rackmount case.

0 CroneNot Posted November 21, 2016 Share Posted November 21, 2016 I like the idea - I did a mod to that effect, but I used a small power supply to power 6 drives, I ran out of power connector from my HDD and didn't want to use y-power connectors. With the supply you're using, did you set it up so when you power on it starts. or do you have a separate switch for it ?- I ran 2 pins from the new supply (green and black) to the main supply so when the main powers up the smaller powers on - power down is the same. I like it alot. Well done Quote Link to comment Share on other sites More sharing options...

Well done Have you seen these? https://www.servethehome.com/supermicro-cse-ptjbod-cb1-jbod-power-board-diy-jbod-chassis-made-easy/ http://www.newegg.com/Product/Product.aspx?Item=N82E16816101800 They're a lot more expensive than they have a right to be IMO, but allows you to handle a normal PSU with any case's power button.
