Title: ZTEX infrared images Post by: Andows on August 27, 2012, 01:12:49 PM I took a couple of images of my ZTEX 1.15x. The images were taken with FLIR Systems InfraCam.
The ZTEX-board in question had an extra heat sink in the bottom and bit more powerful non-stock fan; SUNON MB40201V2-0000-A99 (http://www.sunon.com.tw/products/pdf/DCFAN/MB4020.pdf) running at 12V. Board had been mining for a couple of hours with 1.26V on VCCINT. Ambient temperature was about 23°C, air-conditioned room. There is really no point in this, I just wanted to see how hot the board was running and I thought to share these. :) https://i.imgur.com/rbLBs.jpg https://i.imgur.com/wXBWg.jpg https://i.imgur.com/3ZVUK.jpg https://i.imgur.com/QsA9Z.jpg Non-IR images of the board are available for example on the ZTEX homepage (http://www.ztex.de/usb-fpga-1/usb-fpga-1.15x.e.html). The component radiating the most heat (about 70°C) is MOSFET IRF8714PbF next to the buck regulator AOZ1025D. The MOSFET is rated -55°C to +150°C so it should be fine, but on a long run it might be a good idea to perhaps use a small heat sink for the sake of the other components next to the MOSFET...
