CPU running very hot

I currently have an AMD Phenom II X4 965 Black Edition. I was wondering what normal temperature ranges are for this cpu. Mine currently idles at around 60C and goes as high as 76C under full load. The cooling specs are as follows:

An Antec Skeleton case (almost completely open air)
A Bigwater 760is drive bay water cooling unit with included block radiator ect.

These temperatures seem high especially given that the CPU is the only block in my cooling loop and it is completely un-overclocked. I was wondering if i was over looking something obvious or if i had a possible fault in my cooling system. Any help appreciated.

I think it should idle around 30, 76 is too high for full load. If it is water cooled, something has to be wrong.

Never used water cooling myself so don't know what to suggest.

My friend has the same CPU on air and it hits 65 on full load.

Idles at 60? Way to high. You probably need to get the block on better/correctly. That or use thermal paste.

If your PC is a bit old then i would say the thermal paste should be your first option to try out.

That's way too high. I got the same cpu with a Corsair H100 and mine idles at 26 or so, 33 with a nice air cooler and 42 with a shitty air cooler.

you must have a low ambient temp in the room for it to idle that low.

I have plenty of paste on it. Ill check the block to see if its clogged.

Dusty/dirty heatsink and a heatsink that isn't on all the way are the two most common reasons for overheating. Glad you got your problem fixed.
