MSI 970-G43 for non-overclocked CPU

I have FX6300 and MSI 970-G43(I know everyone hates that mobo - but I didn't know that before I bought that). I don't plan overclocking the processor. And I know the mobo doesn't have VRM heatsinks. I can't go for mobo replacement because the online store is not offering me another product for exchange. All I can do is - I live with the mobo and the processor. Is it okay? Or is there anything else I can do? Like installing after-market heatsink like http://www.newegg.com/Product/Product.aspx?Item=N82E16835708011 ? Is it worth the bucks paid?

The heatsinks should help, but don't expect to overclock.
