I am looking at overlooking my i7 4790k for a performance increase but I am currently using the corsair h55 as my cpu cooler. I am looking to run around 4.4ghz and am wondering if this cooler is enough or if I shod upgrade?
I would try OCing with what you have initially. OC your CPU and stress test to see what temperatures your getting under load. Don't go right up to 4.4GHz in one hit. Raise the frequency in small steps with small adjustments to Core Voltage to maintain stability. You will see if the H55 can cope. Remember not all chips perform the same and voltage is what will create heat.
Download AIDA64 and HWMonitor for stress testing. Put them side by side on your desktop. Run AIDA64 CPU and FPU test and check your system temperatures during the test.
You can take screen shots at the 10min mark and post the results here for analysis.
