Yes the SSD itself will be quiet (I have one in my mac too), but I still hear the fans when they spin fast when my mac is hot. Add the iStat Pro widget to your dashboard if you haven't already to monitor the temperatures and fan speeds.
Thank you very much... I am still wondering why my mac is still so hot even if I just have my safari and messengers on. And maybe you are right that my mac's fan was making the noice because now, it is quiet again.
