thank you very much Satesco for reply
I will tray with an other streamreader with TBS6903X
As for the card TBS6903X , I usually use it for a long time !
So, temperature is the same for both programs Crazyscan and IQmonitor .
Now my card is under the Graphic card in PCIe N°03, So I will try to put in PCIe N°01 which is closer to the processor fan, you know I don't have an fan for TBS6903X
for IQmonitor with this card I use scan with "dF and with auto SR" most of time for full Ku 10.7-12.75 GHz...yes it take time but it works ,
I have to be patient .
regards
