Is my block just bad I got a OCZ hydro flow.I have tryed every thing I can think of to get my core temps down.Water temp is around 40c coming out of pump to block.I use arctiic silver compound ,no air but CPU temp is 60c core temp runs 80c on i7 2600 idols 35c .Same block on a e8400 stock would hit 68c.Thanks for any help in advance. One more thing sec CPU is not under full load temp drops to 50c.Only a 4.5 OC at 1.33 volts

Yeah, OCZ is not known for their watercooling products.

It looks as good as any block .Think I mite have to see if a gpu block I got with strange size treads will cool better. just do not want to order fittings out of china.

The looks of a waterblock mean nothing. The fin density and water channeling, in addition to the size of the copper block itself, are the most important features of a waterblock.

u can get a raystorm  cpu head for 50$

Sadly with watercooling it is something like getting a PSU. Basically if you think of a PSU, you don't want to get a cheaper on just to function as your PSU because it has a touch on everything in your computer and if something goes wrong...BLAM everything is busted. Watercooling is similar in that you are cooling your computer in a potentially (I say potentially because it CAN happen) unreliable way sort of how a cheap PSU powers things. You want your waterblocks and radiator and pump to all be near or at the top of the line for its series. For me personally I don't like to risk my several hundred dollar equipment that I am cooling to save some money. Although trust me, I know what a tight budget is like and I would say if a new block such as an EK brand or even swiftech block isn't in your reach it would be worth it to set your computer to stock with the waterblock you have now and save up for a really nice block, you will see a difference.
 
Now if it isn't the waterblock that's causing issues you may want to look into how you mounted the block, too little or too much thermal compound can cause very abnormal temperatures. Keep us posted on your situation :)

OCZ HydroFlow compared to a couple of other blocks on an OC'd E6400 (you may need to scroll):

HydroFlow is +1 deg to an old EK Supreme, or +3 deg to an old HeatKiller 3.0 LC block.
 
http://skinneelabs.com/ek-supreme-hf-review/4/
This review shows a big comparison graph listing the performance of various blocks.
-The EK Supreme bottoms out at ~67.1 deg while the Supreme HF bottoms out at 64.3, a 3 degree difference.
-The HK 3.0 LC bottoms out at 66.8, a 2 degree to the Supreme HF.
- For comparison to the next graph, the Apogee XT bottomed out at 65 degrees, for a difference of ~2 degrees to the Supreme.
 
Lastly, http://www.pureoverclock.com/review.php?id=1392&page=6
- The Apogee XT is ~1.5 degrees higher than the Raystorm.
 
So.....
The OCZ HydroFlow cools roughly 4.5 degrees (follow the Supreme to Apogee XT to Raystorm) worse than the Raystorm comparatively speaking.  And yes, I know I abused maths to get this answer.
Considering that the top performance blocks all cool to within degree or so of each other, this is a substatial improvement.
 
tl;dr - your block doesnt look like its up to cooling your CPU and its time to get a new one.  The Raystorm linked above is a good block without the expensive price tag of the top dogs and cools to about the same.

try re-seating the block.  Only costs you time.  Make sure you have good contact with your thermal grease.

Thanks looks like I will be ordering a new block asap

Before you go out and get a new block try Nateman_doo's suggestion and remove the block, clean up all the old thermal paste and reseat the block. Don't use too much thermal paste, only need a rice grain amount on the CPU. Then check to see what your temps are like. If they haven't improved then at that point I would reconsider getting a new block.

Also what are you using to remove the heat from the water? Are your fans and rads dirty and full of dust? Are your rads getting enough air or are there any air restrictions preventing your fans from drawing fresh air and starving your rads? What else are you cooling in your loop?

Also, has your block been used for any amount of time, and if so, what coolants/additives were present in the loop?  You may have some buildup within the block.  I would also suggest, if you can, to disassemble the block and see if there are any obstructions within the block.

Well I hope its the cpu block just ordered a XSPC RayStorm. I did try every thing I could even put a big squirrel fan by the rad only dropped temps 2 c. that fan is around 800 cmf or more most likely a lot more.I reset block a lot of times with different amounts of tim. from all most non to to much was same temps each way with in 2 or 3 C.
 I blow every thing out only bunny's was in gtx260 and it was not bad.If the new block can not keep my temps down I will add 1 more 120mm x 2 rad.I think I got 2 good fans on rad now Noctua NF-P12-1300 120mm 1300rpm Fan x2 its rated at 54 cmf the rad is made for slow rpm fans.
Wish me luck want to start building a p67 comp to go with this z68 sli one.
Thanks for all the help
Will post here after I put new block on.

+ 1 to Fiius .Got the XSPC RayStorm and jumped my OC to 4.6 to see how it cools.CPU has not gone over 63 c cores 61c.Now that is nice before even at stock clocks that ocz was hitting high 70 s.I am only 20 min. into my occt linpack . I think if temps stay like they are I should be able to get a 4.8 24/7 OC.
THANK you all for the help

Your welcome but plz throw out the old cooler stomp on it hehe

Update getting second 120mmx2 rad.My temps are good running tests but when folding they are in mid 70s..Thinking on a black ice rad but not sure if a 140mm or a 2x120mm rad got room for ether. All this to fold what the hell. puts off building second comp a bit but.
