High temperatures for closed loop water cooling

Hello,
I have an i5 2500k with an Antec Kuhler H2O 620. I used to have a Gigabyte Z68X-UD3H-B3, and the CPU ran at around 37 degrees idle. However, now, I have a BIOSTAR TZ77XE3, and the i5 2500k is overclocked to 4.0ghz. However, I'm getting 55-65 degrees idle, and as hot as 80 degrees under load.

What exactly is going wrong? I've tried reapplying thermal paste. Also, the bracket at the back that is stuck to my motherboard has one side of it pushed against the ends of capacitors, but the bracket seems to be contacting the motherboard just fine.

Thanks

I would like to know as well.

I swapped back to the stock Intel cooler, and it still idles at 55 degrees.
However, I dropped back to stock clocks, and it reads at 45-50 degrees.

Is the Biostar motherboard really heating up my CPU that much?

Ambient temperature is 16 to 18 degrees Celsius.

I think it might have something to do with voltage right now. When idling, my CPU runs fluctuates between 1.07V and 1.27V.

Can someone here give me decent voltage/BIOS settings for idling and overclocking?

I don't own any more LGA 1156 cpus.
