Will a corsair H80i give more cooling performance than a corsair a50?

Solution
The H50/H80 won't give as much cooling as a Phanteks PH-TC14-PE, DH-14 or 15 or a Cryorig R1.

-Those air coolers provide more cooling than any 120/140mm CLC

-A H110 (1500 rpm) can match the 1st two air coolers, not the other two

-A H100i can edge the air coolers but at about 4 times the noise level.

There's nothing wrong with 68-70C ... but 100% running what ?

Solution
My son's 2600k box is setup with multiple BIOS Boot profiles so he can select which set of BIOS settings he wants to load:

1. 24/7 is it 4.6 Ghz
2. Extreme Gaming is at 4.8 Ghz
3. Testing is a highly customized group of settings (HT off for example ... saves 7C) that hits 5.0 Ghz.

He's using a Thermalright Siver Arrow Air cooler. These were our (1st day OC Settings) and Core Temps .... little tweaking dropped them some and also TIM cured so that we were at 75C at 4.8
