65C isn't good but within what the cpu can handle, but 45-55C is more within tolerances. To increase cooling, simply open(leave open) the case and check all those fans. Inspect the current cpu heatsink fan setup(HSF). You can replace the OEM or factory HSF with a copper core if not already. Plus, install or replace entire HSF with copper core and larger fan setup. Get, what seems to fit and work for you, spend a few $$$, and certainly check the rest of the fans. Plus, make sure all dust is removed for best operation. The quickest and surest short term cure is to use a household fan place at open case and blow-in. I use a simple 6in. desktop fan and that works well and quiet. No central A/C here but my temp is 52C in summer, around 48C in winter. lower if window open. Arrange any wire harness.cabling is routed to allow best "air circulation" of what you do have, plus if possible add a 2nd case fan, possibly in an open spot for that. Of cosue if you can decrease the room temp, that's a plus.
Hey i'm in Jamaica.
I don't Have air conditioning and my athlon 2200+ is overheating. If it wasn't for the motherboard protection the chip would be fried. I basically compute with the risk of the machine shutting down at any moment because of the processor reaching critical temperatures. What can i do. and is 65 degrees celsius a good average operating temperature.
