I have the same cpu and heatsink (with Scythe gentle typhoons in push/pull). You may see a slight increase, but your cpu is running plenty cool. I run mine at 4.2 no problem.
Is there much of a difference in which case fans I use? I was going to get a 140mm coolermaster fan as an intake for the side and a 200mm for a exhaust on the top but now I'm wondering if maybe the typhoons would be better. Also, I've had this cooler for a while and I thought maybe I should get another fan for it on the other side but maybe thats overdoing it.
Grab a couple of 120mm Gentle Typhoons and set up a push/pull config with them. You can reuse the original fan from the Hyper 212 as the side intake fan. I currently have my i5 3570k at 4.2GHz on stock voltages idling at 28°c and pushing up to 50°c during heavy gaming sessions. I use a Xigmatek Dark Knight cooler with two 120mm F12PWM fans from Arctic Cooling and not only does it cool wonderfully, but it's damn near silent.
EDIT: My rig as she is at the moment
