I installed a crucial M4 SSD drive and upgraded the RAM to 8GB yesterday and since then I've noticed excessive fan noise. When the computer is working the fans start up and it sounds like a mini jet engine. I've never had a computer with such noisy fans. Is it normal to be so loud and to sound like a small jet engine? I assume it's more noticeable since installing the SSD as the processor has more demand on it due to the hard drive speed? It kicks in with 'simple' tasks such as importing photos into iphoto. They are importing much much faster than they did with the HDD though.
