are there any gadgets that have accurate thermal probes and fan control in one unit to fit in a drive bay? would be great if there was but cant find anything...
if not what do people do to get equal piece of mind and control? i'm fed up of wondering if temp software is accurate i want a second (hard wired) opinion
and fan control cuz my nice silent case just doesn't cut it... need more beef but without the noise for normal application -> fan controller...
