A third heatpipe ist connected to another heatsink in the back of the htpc.The groundplate itself is working as a heatsink while transferring heat to whole case / cooling the power supply.<img src="http://www.golffan.org/AV6/pics/IMG_5970.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />  <img src="http://www.golffan.org/AV6/pics/IMG_5971.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />The core system (Mainoard, Core i3 530, 4GB Ram, SSD) needs about 20W IDLE and 60W (full load). With all the other components (3,5" HD, DVB-C, DVD, Y.A.R.D., Display, Bluetooh Dongle) power consumption is between IDLE 35W (MePo in Basic Home) and load 50W (HDTV redording while playing a x264 1080p video).The IDLE temperature (MePo) of the whole system/case is 35°C, while the CPU/GPU is about 45°C. Under full load (Prime95 - 65W) for several hours temperature wil raise up to 45°C (system) an 70°C (CPU/GPU).OK, here two pics of the result:<img src="http://www.golffan.org/AV6/pics/IMG_5974.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /> <img src="http://www.golffan.org/AV6/pics/IMG_6133.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /> <img src="http://www.golffan.org/AV6/pics/IMG_6146.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />greetings,Christian</blockquote>
