trying to overclock amd fx 6300 at 3.5 ghz updated

[mill1rbt2]

I did not want to update an old thread because the last one I posted is from may 2014 but I'm still trying to overclock to 4.5ghz as recommended from a previous reply...I tried googling and downloaded cpuid hwmonitor to test the temperature of my cpu and it look's like the temperature of the amd fx 6300 should be at a good cool temp...after I put the box fan on the open left side of the case it's gone down from 20C to going up and down from 13C to 14C and back..I have attached a picture to look at called cpuid hwmonitor info...also instead of my power supply having only 13 amps I googled to find out the +12v version 1 is 8 amps and the +12v version 2 is 13 amps and I should be at 21 amps with the two 12v rails combined..I also looked newegg at a corsair 750m that has 62 amps on one 12v rail in case I need it...in amd overdrive the cpu vid is currently at 1.1500 and I can up the meter to 1.2000 I did not press apply yet..when I up it to 1.2125 those number's are highlighted in orange and then a light pink when at 1.270 and finally highlighted in dark red at 1.3250...can I get to the 4.5ghz some how with this setup and the box fan sucking the hot air out and improving the cooling?
