I have a force3D HD 5770 1GB and on the net everyone says this card doesnt allow fan speed changes,its not thats its hot but i want it cooler so i can oc properly,right now in summer time it reaches 75C in bf3 which is not that much but is there a way to change it somehow?
you will have to lay on the board electrical pcb and if the card is not made for this , you could end up with a non working card .if you could try the check the air flow in your system so it could cool daonw the card. ( side note my graphic card was made with this option for the fan speed and the revision number after of the same card is not having it )
you could but be carefull and monitor your temp . i use the gpu monitor from them to the desktop it read temp and fan speed +some other thing http://www.myfavoritegadgets.info/
Is it possible to use RBE and make fan spin 100%?(I have it open i see some numbers but im not sure,ive downloaded the force3d 5770 bios into it but when i go to acquire/flash button and do analyze it says it cannot find my gpu)
you will be restrain by the memory speed you have and your motherboard support a max of 1333 mhz also this psu is on the limit ,i would give a look at the 7790 or a bit lower . for all the parts you have on hand .
