yes mate relatively easy
Bit blurred your picture however I would think you could fit a normal 40mm fan on there if you can remove the chipset heatsink (some are glued to chip)
If you can remove (usually two small plastic retainers on corners) it the it can be replaced.
Had a quick browse around found this

Not sure about fixing tho unfortunately cant see properly.
Alternatively the Zalman heatsink at the bottom of that page may do. You wont need a fan if you have decent airflow

Your best bet is to send an email stating your board and ask if it will fit
