NZXT Kraken X61 - Abnormal Temperatures?

[g-unit1111]

I can post a screen from NZXT's Cam software if needed but last night after a round of gaming I was getting temps in the ~55'C range and I only have the CPU (Intel Core i5-3570K on Gigabyte GA-Z77X-UD3H) overclocked to 3.8GHz. The case I have is the NZXT H440 and I didn't make any real modifications to it other than replacing the stock fans with LED fans. Any reason I'm getting these high temperatures on this cooler? Does anyone have any remedies for this?

What LED fans are they? Were the temps okay before changing the fans? TBH 55c isn't that bad.

I'm using Corsair AF140s in place of the stock fans.

Were the temps the same with the previous fans?

I don't know since I didn't use the fans that came with the cooler initially. I might try cleaning off the pre-applied thermal compound and using some Noctua NH-TH1.
