Sorry mate but I am a little confused as to what you want against what you need. On one instance you say you want an HDD that reports the temperature and then you say you need to keep it at a certain temperature (thermostat). Which is it? Surly the best thing would be to run the whole machine at absolute Zero -300 deg C (probably wrong but close enough) but let's be sensible. If the machine is set to run at, say, 30 deg C and you have the ability to maintain this temperature within an acceptable range, say, 5 deg C +/- then everything will be hunky dory. However, your main concern is not keeping the temperature static (thermostat) but keeping it @ 30C. If you have the means to fit a large enough fan (s) and shift a reasonable amount of air I can send you a fan control circuit plan with PCB routing that will give a reasonable "hysteris" (probably spelt wrong but means bounce or range between on-off) with stabilized supply running on 12vDC. I designed this for automotive cooling using electric fans but works Ok for other things. Temp range is easily adjustable. Fan speed is dependant on several things - see model slot cars and rewinding the motors. One being voltage another is amperage and obviously the resulting speed of rotation. Fans, like boat propellers and aircraft propellers, are suspectable to "cavitation" - in a boat this means the prop will create eddies and bubbles and eventually stop pushing water and rotate in "air". Likewise above a certain speed the airflow lessens to a degree that it becomes inefficient. Taking the above into account and presuming you have a reasonable ambient air temperature good ventilation of the computer case with good internal air flow with proper (sic) flow direction over, past, by way of - the hot drives etc you shouldn't really have a problem - or is the problem imaginary? Have a nice day! Sir Hugh of Bognor Intelligence is not knowing the answer but knowing where and how to find it!
