Do you need to get a new fan/heatsink/thermal paste to overclock an hd3200 safely(I have a Gateway GT5694 desktop), even if you just overclock a little bit? What's a safe way/amount to overclock without risking anything, or at least risking VERY little. Sorry if I'm being a dumb noob. Thanks
Nah, a fan blowing on the heatsink can certainly help as the 3200 does run hot, but it's not necessary to overclock a couple hundred Mhz. If you're running a gateway you might just wish to check if AMD Overdrive is still available (it's been a while since I heard any mention of it) if not, you can check if an overdrive option is available in Catalyst Control Center (download latest driver package from AMD directly).
overdrive is still available as a download from amd.
also, I do not know how the OP clocked his, but I run my HD3200/780G at 700MHz up from stock 500MHz and never have an issue. Not to mention that it has never gotten above 59C.
