Jamr Posted December 21, 2012 Author Share Posted December 21, 2012 Here's another one to consider: http://www.thermalta...35&ID=1882#Tab2 I think the phantom power used by the power supply would be very close to the power used by the USB fan; these fans use very little power. Phantom power if there is any, does not even register on my meter. A typical computer fan draws roughly 4.5 watts. That is a huge difference over time 24/7 Link to comment Share on other sites More sharing options...

That is a huge difference over time 24/7 The Thermaltake cooler draws about 1 watt, which I think is more than reasonable. IMHO, 4.5 watts is not a big deal. It's only half of what a typical nitelite draws. You're talking about less than what it costs to power a 100 watt bulb for 1 hour. I'm all for energy efficiency, but I think worrying about these levels is a bridge too far. Link to comment Share on other sites More sharing options...
Just Checking Posted May 8, 2013 Share Posted May 8, 2013 I have a CRT for my server too. It's the only display I have besides the attached displays of the laptops in my network. I measured the power consumption of the CRT at 50 watts. The power consumption of the N54L with 5 HDD's, 1 SSD, a USB 3.0 PCIe card and the processor running at 100% is 75 - 83 watts. Power consumption at idle was measured at around 40 watts. Adding a RAC increases power consumption by 10 watts. External HDD's at idle take about 5 watts each. When spinning at full speed (7200 rpm) and transferring data at maximum rate, the Seagate 2TB & 4TB drives I measured consumed about 10 watts each. With my server operating at full capacity and with three external HDD's attached the power consumption went to 95 watts + the 50 watts of the CRT. From the picture, there are a couple 8-port switches (5-10 watts each), a 2-disk NAS (20-30 watts), a 4-disk NAS (40-45 watts), and possibly a router (25 watts). That closet looks to be about 1.25 meters wide by 1 meter tall. That closet should easily get 20 C. warmer than ambient. It would be higher if the doors didn't have louvers.

pcdoc Posted May 9, 2013 Share Posted May 9, 2013 I keep mine an the extra bedroom so I can easily work on it if I want to. Link to comment Share on other sites More sharing options...
ikon Posted May 9, 2013 Share Posted May 9, 2013 LOL. You need a couple of pictures on the walls pcdoc Or maybe some CCR posters Seriously, I am a little bit surprised you have the units on the carpet where they can suck in dust. I realise you likely don't go in that room all that much, but I would have expected them to be on a table of some kind. You have no issues with dust?
