CPU running hotter on Scythe Katana 3 than on stock cooler.

Greetings,I got this cooler for my CPU AMD Phenom II X4 B50 3.2ghz.I mounted it on CPU correctly,it is firm against the CPU.I mounted the fan+aditional fan blowing on it.After arround 20 minutes of BF4 multiplayer,I checked temperature in SpeedFan.It was 58c while on the stock cooler it is arround 54.I also applied new sylicone based thermal greese.Cooler cooper heatpipes and other parts of the heatsink are not even warm.Thanks in advance.

How did you apply the thermal paste?

How did you apply the thermal paste?

I applied it in a normal amount in a square.Yesterday after I removed the cooler I found it there has been alot of air bubbles like on this picture:

So I removed the paste and put a new one,with this ammount:http://lib.store.yahoo.net/lib/svcompucycle/article-thermalcompound2.jpg
Temperatures got just a bit better,now I am idling at 35-40,I will inform you what is the load temperature after some gameplay of BF4.Also I have undervolted the cpu to 1.25(not sure what is stock since this one is unlocked from X3 450) and I also overclocked it arround 3.471 Ghz.

After a round of BF4,max temp is 54C.Is that normal,I have reverted to stock speed of 3200 mhz,and voltage is arround 1.525

Yeah that cooler can't handle overclocking too well. If you'd like a new cooler for overclocking, I'd be happy to help.

As for the temps, I am unfamiliar with your CPU's general temps with that cooler so I cannot say if the temps are normal but I can say that they are ok.

OK after some time I finaly managed to make load temperatures only 43C.
First,heatsink wasn't properly fastened,if you fasten one side,other will be much harder to fasten and because of that I was afraid I could break something but even if you fasten one it will look like it is very firm,I tried to move it and it doesn't come off.
Second,for some reason cpu voltage was set at 1.6,so I put it to arround 1.25
