Cheap heatsink AM3+

[Shihanshu]

Looking for a nice heatsink to OC to 4-4.5ghz on my Fx 6300

Best deal is the 212 EVO , but I doubt you will get 4.5 or 4.6.

You can also find the 212 + which is the previous model for about $10 cheaper. I also doubt you'll get 4.5 or 4.6.

I think you can hit 4.5GHz with a decent motherboard (8+2 phase) if you keep your volts down.

Never happen with an el cheapo board without divine intervention.
