Regarding OCing, is the ThermalTake Riing12 fans good? Or the IDCooling 12025 Fans? I have a mATX PowerLogic Case (forgot model) with slot for an exhaust fan (I think, rear portion inner side) of the Casing. Both of these cost a little cheap but these are my only options as I'm somehow tight on budget. Also, what is/are a good fan to replace the stock AMD A10-7870K Fan? (Planning on using the stock heatsink) A cheap option would be great. I think the stock fan is 60mm or 70mm. Thanks in advance
