CPU Temps too high / Fan config

I'm regularly reaching CPU temps of over 50C whilst under hardly any load, and as a result my H60 fan is pretty loud :/

My CPU (i7 2700k) is auto-OC'd by ASUS's AI Suite (on a P8Z77-V PRO) to 4.8 from 3.5Ghz, which could be the issue, but I still want to know the best configuration in terms of case fans.

I have the NZXT Phantom 410 with included 2*120mm, 1*140mm and another of the same 140mm from a friend's build, along with the H60's fan.

Currently, I have a 140 front intake, 120 side intake, 140 top exhaust and the H60 exhaust (in pull config) out the back. The extra 120 I have had on the other side of the radiator the past few days to have the H60 in a push pull config, but have just decided to remove it considering that the fans have different RPMs etc and only the pulling one is controlled as a CPU fan.

What do you guys recommend as the best setup (without buying new fans)?

Cheers in advance :)
 
What's the difference at idle between the temps inside your case (motherboard sensor) and your room temperature? What's the difference in temps between your motherboard and CPU? Looking at these variables will help assess whether the problem is with airflow within your case or a poorly performing cooler.

I have a mid range air cooler and a fairly well cooled case, at idle with fans running silently my cpu is 3c hotter than my motherboard which is 3c hotter than my room temps. Under load my fans kick in and the difference between outside the case and inside drops to 2c but obviously the CPU temps start climbing.

If the difference between outside and inside your case was the greater I would look at airflow, if the difference between motherboard and CPU temps was the greater I would look at your cooler.
 
What PieEater said.

Not to be harsh but your H60 is a noisy bottom level H20 cooler and compares with mid-level air coolers.

Temps on i7 920 @ 3.6GHz
32c delta and quiet NoctuaNH-D14
34c and loud H60
35c and quiet Noctua NH-U12P-SE (My Phanteks is 10c cooler than my NH-U12P-SE was)
45c stock cooler
 
Although I've never used them myself, from what I've heard some Auto Overclock programs set overly high voltages than what would be necessary. It might be worth checking the voltage it has set and seeing if you could manually reduce it - this should also reduce temperatures.

I know it wasn't what you asked but I thought I'd just suggest it!
