How CPU Overclock works?

Hello, i have slight concern about my overclock on AMD Athlon II X4 620 (2.6 Ghz Stock) Overclocked to 3.00 Ghz using FSB. I have locked processor with maximum multiplier of 13, and stock FSB at 200 Mhz (i added 31 to a total od 231Mhz), Stock Voltage is 1.404 Vcore.

There is multiplier for the HT Link and i lowered it to 9x = 2080 Mhz but there is no multiplier for the NorthBridge, there is only a set speed, even when i set it at 1800 for example it still run's at 2300Mhz.

Now i have looked at other people's athlon's and saw that they have much lower voltage on this chip, and i tried undervolting it but seems my motherboard doesn't support that, i only have option to add voltage (Foxconn A88GMV AM3) , I have tested Prime 95 for 2 hours, and it is stable, also i have been using it for the past 2 week's without stability issue's while gaming and surfing, i am using tower cooler LC CC 120 (cpu temps never go past 40), and i have 1 fan directly on the vrm's and mosfets.

Now the question :
can you hurt mobo, or cpu, if it's stable at stock voltage overclock ?
i know that adding voltage especially on low end mobo without heatsink on vrm's can harm it, but at stock voltage, is there any downside for the mobo/cpu ?

Thank's in advance.

Regards,
Aleximus.

It's about heat. If your vrms get too hot then that can be harmful, no matter what voltage you use. Increasing voltage also increases the possibility of overheating the component, but just because you run stock voltages doesn't mean temperatures will remain safe. Small heatsinks can be bought, and stuck on to the components with thermal tape if you want to lower the risk of damage.

Thx for the answer, that was bugging me, because i know at touch how hot vrm's were before OC and i noticed they are quite a bit hotter now after the oc, so i wanted to clarify that,tahnk you once more. About the heatsink, i will be making a custom one from a old gpu cooler, and will use termal tape to "glue" it to mosfet/vrm's as a side project.
