Okay, first off, here's my computer specifications
Motherboard : ASRock M3A770DE
CPU : AMD Phenom II X4 955e @ 3200MHz (Revision: RB-C3)
Memory : 8gbs of DDR3 RAM
Video Card : GTX 560(Non ti version,not Overclocked)
Case : Master Cooler 310

*Overclocking my CPU
    My AMD Phenom II X4 955 is running at clock speeds (3.2GHz) and I'm still using the stock AMD cooler. At idle it runs between 31C-33C and under 90-100% load, it runs between 55-58C. I'm curious to know if I can overclock with the stock cooler? I checked in Core Temp and when my CPU runs at max frequency (3.2GHZ) the voltage is at 1.4v; I have Cool n' Quiet enabled. Is this core voltage too high? I've read where some people have gotten their Phenom 955 up to around 3.6 GHZ using Lower voltage.

    If I do need a Aftermarket cooler, I have some limitations. The case that I'm using now is somewhat small, has only 1 intake and exhaust fan, and has poor ventilation due to the HDD cage completely blocking air intake from my front fan, so I've been using my computer with the side case off and that's been going good so far.

    I know that my system is pretty dated, considering I'm attempting to play games such as Battlefield 4, but I'm desperately trying to squeeze out a bit more performance without spending unnecessary amounts of money.

If you need a safe and long lasting CPU overclock a good cooler is recommended. I recommends you a Cooler Master Hyper 103 its and excellent compact cooler with it you can do a decent overclock.

Generally motherboards will use the max stock voltage a chip is rated for by default. This is to insure stability without needing your average consumer to make adjustments.

Since your CPU is already set at 1.4v you may be able to overclock it a modest amount without greatly increasing temperatures. Simply raise the multiplier by a couple and stress test while checking temperatures. Repeat this until you have reached your limit. Any serious overclocking will require a good after market heatsink.

You could probably also lower the voltage at stock speeds to help lower temperatures if you wanted to go that route. To achieve this you need to lower your voltage by 0.25 and test for stability, repeating until instability occurs. Then raise it back to your last stable voltage.

Thanks for replying. I did a Google search of Cooler Master: Hyper 103, and couldn't even find a purchase link to either Newegg or amazon.

Also, here's a link to my computer case http://
On my motherboard the RAM slots are pretty close to the cpu cooler. Do you think I would have any problems installing this cooler?

Thanks for replying. Honestly, I planned on Overclocking as much as someone with a lot of experience would recommend. I'm not sure how much I should OC or how much of a performance I would gain from it.

I guess it would be a good decision to get a aftermarket cooler though. It's just I'm pretty confused on what cooler to get. My case is pretty small and the RAM slots on my motherboard are close to the cooler. I would love to get a CM Hyper 212+, but it's more than likely too big for my case and motherboard.

I have a cooler master N520 found here http://www.newegg.com/Product/Product.aspx?Item=N82E168... that is a little shorter than a CM Hyper 212+ and may fit that case, It will be close.

Mine measured approx. 6.25 inches from the wall behind my motherboard to the end of my cooler. While not quiet as good as a 212+ it is very similar in performance. Test results that I have read put it within 2-3C of the 212+.

Good luck to you whatever you decide!

Your motherboard is a normal sized one and it will fit. In case if you feels the RAM a bit too close you can change the RAM to the next slot.

When I searched for online retailer I found a link that list the cooler and dont know whether the retailer is good or not......

Site seems a little sketchy to be honest haha. Think you could recommend me a small, reliable cooler for AMDs that's on NewEgg?
