Fan won't stop running once it starts until I sleep my laptop

Hey guys,

I noticed recently that my laptop's fans won't stop spinning loudly once they start (usually during gaming). Sleeping the laptop will stop the fan (even if only for a second.) My temps are 65-75 during gaming but drop immediately after I stop an idle of 45-65. When this problem occurs cpu usage seems normal (core 0 ~ 10%)

I have also noticed that hot air only seems to come from roughly half of the vents at the back of the laptop.

I haven't dusted since I bought it (a year?), although I did vacuum the vents. :D

Any help or advice on this problem would be greatly appreciated. Thanks

specs:
nvidia gtx 765m
i7-4700mq
8gb ram

Thanks for the help.

I just realized that I might not have made myself clear about the vents thing- hot air is only coming from the right side of a single set of vents. Would this be dust too?
