Un rasp avec des radiateurs<\/p>\n

\"image\"<\/a><\/p>\n

L’ajout de radiateurs fait baisser la temp\u00e9rature du processeur de quelques degr\u00e9s pendant 1 minute, mais revient \u00e0 son niveau initial (soit environ 57\u00b0C).<\/p>\n

La t\u00e9p\u00e9rature du rpi est disponible ici :\u00a0\/sys\/class\/thermal\/thermal_zone0\/temp \u00a0 <\/strong>\u00a0(il faut juste diviser par 1000 !)<\/p>\n

voici un script munin-node pour superviser ce param\u00e8tre :

\n. $MUNIN_LIBDIR\/plugins\/plugin.sh<\/p>\n

if [ \u00ab\u00a0$1\u00a0\u00bb = \u00ab\u00a0autoconf\u00a0\u00bb ]; then
\nif [ -r \/sys\/class\/thermal\/thermal_zone0\/temp ];then
\necho yes
\nexit 0
\nelse
\necho \u00ab\u00a0no (missing \/sys\/class\/thermal\/thermal_zone0\/temp)\u00a0\u00bb
\nexit 0
\nfi
\nfi<\/p>\n

if [ \u00ab\u00a0$1\u00a0\u00bb = \u00ab\u00a0config\u00a0\u00bb ]; then
\necho graph_title CPU core temperature
\n# echo graph_args –base 1000 -l 0
\necho graph_args –lower-limit 30 –upper-limit 40
\necho graph_info CPU core temperature
\necho graph_category sensors<\/p>\n

echo temp0.label Core
\necho temp0.cdef temp0,1000,\/
\nexit 0;
\nfi
\necho temp0.value `cat \/sys\/class\/thermal\/thermal_zone0\/temp`

\nAvec une l\u00e9g\u00e8re ventilation (vitesse 1 sur 3 d’un ventilo de 8cm et aliment\u00e9 en 9v au lieu de 12v), les effets sont beaucoup plus impressionnants et durables sur la temp\u00e9rature du CPU : dans mon cas, j’ai perdu environ 15\u00b0C !!!<\/p>\n
