Hello, i am upgrading my old rig from dual core to quad core

so my current specs are :

MOBO : Foxconn A88GMV (AM3)
CPU : AMD Athlon II X2 250 (2x 3.0Ghz, true dual core)
RAM : Patriot 2x2GB DDR3 1600 Mhz
GPU : ATI Radeon HD 4650 1GB (will upgrade to GT1030, for LoL and Overwatch is enough)
PSU : LC Power 600 W
HDD : WD Blue 1TB 7200RPM

I have ordered the
LC Power Cosmo Cool 120 (TDP up to 150-180W)
and an used
AMD Athlon II X3 425 2.7 Ghz

So the cpu is unlockable to Phenom II X4 B25 (2.7 Ghz @ 127W TDP) as specifed by previous owner ( i found it for around 20$ used so i didn't hesitate)

the Motherboard is
Foxconn A88GMV and i will provide the image :

As you can see on the motherboard there is no VRM Cooling, that is my concern and i tried finding the correct answer on the Internet, but some say you need cooling there when using tower heatsink, some say you dont need it at all and some say stick with the stock box cooler.

I just wanted to double check, all i need to do is swap the cpu ? do i need to clear bios by removing battery for 5 minutes? or i just install and play? After stable unlock and some stress testing i wil probably try to overclock a bit, but my concern is pushing 127W tdp even higher on the VRM's
the motherboard have 4+4Pin and psu is good enough so the power delivery shouldn't be an issue.

If VRM Cooling is advised, how can i do it on this board, any tricks and tips ?

Let me see what you guys think i should do/not do.
Would highly appriciate the Solution from you guys on this amazing forum!
Sorry for my English if it's not the Best.

Regards, Aleximus.

That cooler should move enough air around the CPU area. If you had an AIO liquid cooler, then you could have a VRM problem.
Your BIOS will notice the hardware change and will force you to go into setup.

Thx for replies, i wont forget the themral paste xD i bought some CM Essential

Yeah, Athlon II X3 425 is 95W TDP chip, however, once unlocked into quad core it draw's 1/3 from 95W more ( about 31.6 or so per core x4 = 127)

i just check that this mobo support some phenom x6's that draw 125 W, however, Stock cooler provides some airflow over the VRM area, and tower coolers, almost doesn't at all so that is my biggest concer... I dont know how to check if the vrm's are getting hot a lot (aside from touching them lol).

You only need to worry about that if you can't get enough Voltage for your overclock. Just decent airflow there is usually good enough. But I did get from 1.4V to 1.45V by cooling mine on the Dell in my sig. But then Dell wasn't planning on this thing going 4GHz.

Lol xD Intereseting, i would be happy for stable unlock and cooling, maybe push it to 3.0 Ghz if am lucky i geuss, but on the other hand how much am i acctually getting for pushing 4 core's by 300 mhz each ? The core is Deneb, so the IPC is horrible, will test it when it arrives, and then will try to OC to 3.0 Ghz if i get more than 10 fps (since cpu is bottleneck) i will leave it there, if it is <5 fps in benchamrks i will reverse it. Not worth strresing already old mobo for <5 Fps..

That was my frist thought, althou i will check for that later, my main concern is will mobo handle unlock ?

EDIT :
I just saw that people who unlock their CPU can't measure the Temps, in case i didn't use aftermarket cooler, how should they know it's stable ? prolonged stress test ?
